The objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings. In the present specification, in adding reference numerals to the components of each drawing, it should be noted that the same components as possible, even if displayed on different drawings have the same number as possible. In addition, terms such as “first” and “second” are used to distinguish one component from another component, and the component is not limited by the terms. In describing the present invention, detailed descriptions of related well-known technologies that may unnecessarily obscure the subject matter of the present invention will be omitted.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is a flowchart of a polymer production scheduling method according to an exemplary embodiment of the present invention.
Referring to FIG. 1, the polymer production scheduling method includes a production information determination step S100, a sales information determination step S110, an ERP establishment step S120, a sales information estimation step S130, and a scheduling step S140. do.
Production information determination step (S100) determines the production information including the production status of the current scheduling period of the polymer and the production plan for the remaining scheduling period of the current scheduling period. When the production is scheduled for the next scheduling period at a predetermined time in the current scheduling period, the production information from the current scheduling period up to the point where the scheduling takes place becomes the production status, and thereafter, from the time point until the remaining scheduling period in the current scheduling period. Production information becomes a production plan. In the present specification, the production information refers to information related to the production of the polymer, such as the type of polymer, the amount of production, the property and shape produced, the grade produced, the cost of production, the cost, and the like of the produced polymer or polymer material.
The scheduling period and the production plan will be described later in detail with reference to FIG. 3.
In the following, repetitive description is omitted for simplicity of the specification.
When the production status of the current scheduling period and the production plan for the remaining scheduling period are determined in the production information determination step (S100), this time the sales plan for the remaining scheduling period of the polymer, the next scheduling period of the polymer in the sales information determination step (S110). The sales information is determined, including the available sales amount and the available sales amount for the next scheduling period. In the present specification, the sales information refers to information related to the sale of the polymer, such as the type of the polymer to be sold in the future, the property of the polymer to be sold, the grade and the target sales amount by the scheduling period.
As shown in FIG. 1, the polymer production scheduling method according to the present invention, when determining the sellable amount for the next scheduling period, corresponds to not only the sellable amount of the next scheduling period corresponding to the next scheduling period, but also the next scheduling period. Consider all the sales available for the next scheduling period. On the other hand, the saleable amount is information received as an example of how much a specific product can be sold to a specific company from sales representatives and may be displayed as a range of minimum and maximum values. Accordingly, the polymer production scheduling method according to the present invention has the advantage of scheduling the production of the polymer in the long term.
Once the production information and sales information is determined, the ERP establishment step (S120) determines and manages the inventory for each grade of the polymer and the resources for producing the polymer. In particular, the ERP establishment step may manage the appropriate period inventory for the next scheduling period, in this specification, the appropriate period inventory means the amount of inventory to be sold until the production point of the next scheduling period.
The present invention has the advantage of efficiently coping with price fluctuations in the mid- to long-term polymer by managing the available amount of the next scheduling period and the appropriate period inventory.
In the ERP establishment step, the inventory of each grade of the resource is not only monitored, but the inventory of the resources is actively managed so that the production can be performed smoothly as scheduled according to the scheduling result determined by the scheduling step described later.
Then, in the sales information estimating step (S130), the initial inventory amount of the next scheduling period is estimated using the production plan for the remaining scheduling period and the sales plan for the remaining scheduling period. At this time, the initial inventory amount of the next scheduling period may be estimated by adding the value of the polymer subtracted from the production plan for the remaining scheduling period to the sales plan for the remaining scheduling period.
If the initial inventory amount of the next scheduling period is estimated, the scheduling step S140 schedules the production during the next scheduling period in consideration of the estimated information and the sales information. As described above, the sales information considered herein may include the sales plan for the remaining scheduling period, and the available amount of the next scheduling period and the next scheduling period.
Through the scheduling step (S140), finally the production amount and sales amount of the polymer can be determined.
As described above, the polymer production scheduling method according to the present invention considers not only the sellable amount of the next scheduling period but also the sellable amount of the next scheduling period and reflects it in the scheduling process. Therefore, it is possible to draw up a cost-effective production plan.
2 is a flowchart of a polymer production scheduling method according to another embodiment of the present invention.
Referring to FIG. 2, the polymer production scheduling method includes a production information determination step S200, a sales information determination step S210, an ERP establishment step S220, a sales information estimation step S230, and a scheduling step S240. do.
Production information determination step (S200) determines the production information including the production status of the current scheduling period of the polymer and the production plan for the remaining scheduling period of the current scheduling period.
However, unlike the production information determination step of FIG. 1, the production information determination step S200 of FIG. 2 is facility related information such as facility information, maintenance information, and operation information of a factory related to the production of a polymer during the next scheduling period. Further determine specifics, including information on supply and demand for raw materials or personnel operations.
Specific details herein are information representing factors that may affect the production of polymers in production equipment. For example, even if a stock of a particular resource is sufficient, if the storage tank of that resource fails, it should be scheduled to produce the target polymer without that resource. On the other hand, manpower for the operation of the polymer production facility may not be available in some circumstances, in which case the operation of the plant is limited and all of these external factors are taken into account in the polymer production scheduling.
If the production status of the current scheduling period and the production plan for the remaining scheduling period are determined in the production information determination step (S200), the sales plan for the remaining scheduling period of the polymer, the sales available amount of the next scheduling period in the sales information determination step (S210). , And sales information including the available sales amount for the next scheduling period.
As shown in FIG. 1, the polymer production scheduling method illustrated in FIG. 2 also corresponds to the next scheduling period together with the available sales amount of the next scheduling period corresponding to the next scheduling period when determining the sellable amount for the next scheduling period. Consider all sales available for the next scheduling period. Therefore, there is an advantage in that the production of the polymer can be scheduled in the long term.
Once the production information and sales information is determined, the ERP establishment step (S220) determines and manages the inventory for each grade of the resource for producing the polymer and polymer. In particular, the ERP establishment step may manage the appropriate period inventory for the next scheduling period, in this specification, the appropriate period inventory means the amount of inventory to be sold until the production point of the next scheduling period. The present invention has the advantage of efficiently coping with price fluctuations in the mid- to long-term polymer by managing the available amount of the next scheduling period and the appropriate period inventory. The ERP establishment step of FIG. 2 is similar in operation to the ERP establishment step of FIG. 1. Therefore, repetitive description is omitted for simplicity of the specification.
Then, in the sales information estimating step (S230), the initial inventory amount of the next scheduling period is estimated using the production plan for the remaining scheduling period and the sales plan for the remaining scheduling period. The sales information estimating step S230 of FIG. 2 is similar in operation to the sales information estimating step S130 of FIG. 1. Therefore, repetitive description is omitted for simplicity of the specification.
If the initial inventory amount of the next scheduling period is estimated, an accuracy checking step (not shown) for checking the determined production information and sales information and the estimated initial inventory amount may be performed. In the present invention, the various information for which scheduling is used is an important factor in determining the production scheduling of the next scheduling period. Therefore, if any one of these pieces of information is lost during the communication process or during the delivery or in the morning, a huge loss may occur in the later production process. Therefore, in order to prevent this phenomenon, the accuracy check step checks the information used for scheduling.
The scheduling step S240 schedules the production during the next scheduling period in consideration of the estimated information and the sales information. As described above, the sales information considered herein may include the sales plan for the remaining scheduling period, and the available amount of the next scheduling period and the next scheduling period.
As such, the polymer production scheduling method according to the present invention takes into account the peculiarities of the next scheduling period when determining production information, and may check the accuracy of information used for scheduling before performing scheduling through an accuracy checking step. . Therefore, it is possible to easily cope with various failure situations that may occur in the production system, and to prevent scheduling errors.
3 is a graph illustrating a scheduling period meaning in the present invention.
In this specification, the scheduling period may correspond to various time periods such as 1 year, June, March, January, 2 weeks, 1 week. Shorter scheduling periods may mean shorter product lifetimes or a more sensitive polymer.
FIG. 3A illustrates a case where a scheduling period corresponds to one year, and FIG. 3B illustrates a case where a scheduling period corresponds to March, that is, a quarter year. 3C and 3D show the case where the scheduling period corresponds to January, that is, the production scheduling is performed monthly.
In particular, FIG. 3D is a graph illustrating the previous scheduling period, the current scheduling period, the next scheduling period, and the remaining scheduling period used in the present specification. Referring to the figure, scheduling occurs at time A of M-1 month. That is, time point A is any time point in the middle of M-January which is the current scheduling period. Then, the period from the time point A to the start of the next month, M, becomes the remaining scheduling period of the current scheduling period. On the other hand, the period from the end of M-February to the time (A) may be referred to as elapsed time. That is, if scheduling is performed at any point in the current scheduling period, the current scheduling period is divided into an elapsed period and a remaining scheduling period based on the corresponding time point.
In the present specification, the next scheduling period, the current scheduling period, and the previous scheduling period are denoted as M month, M-Jan, and M-February, respectively, but these are merely for convenience of understanding and the present invention is not limited thereto. Do.
4 is a flowchart of a polymer production scheduling method according to another embodiment of the present invention.
In FIG. 4, the polymer production scheduling method includes a first scheduling management step S405 and a second scheduling management step S455. At this time, the first scheduling management step S405 is performed in the middle of the current scheduling period, and the second scheduling management step S455 is performed at the expiration of the current scheduling period.
In addition, the first scheduling management step (S405) is the primary production information determination step (S400), the primary sales information determination step (S410), the primary ERP establishment step (S420), the primary sales information estimation step (S430), The first accuracy check step (S435), and the first scheduling step (S440).
The first production information determining step S400 is similar to the production information determining step S200 of FIG. 2, and determines the specifics related to the production of the polymer during the next scheduling period, and the production status of the current scheduling period of the polymer and the above. Primary production information is also determined including the production plan for the remaining scheduling period of the current scheduling period. Since the production status and production plan have been described above in detail with reference to FIG. 3, repeated descriptions are omitted for simplicity of the specification.
When the production status of the elapsed period and the production plan for the remaining scheduling period are determined, the primary sales information determination step (S410) includes the primary sales plan including the sales plan for the remaining scheduling period of the polymer and the available sales of the next and next scheduling periods. Determine estimated sales information.
As described above, the polymer production scheduling method according to the present invention has an advantage in that it is possible to schedule the production of the polymer in the long term because it considers the sellable amount of the next scheduling period when determining the sellable amount for the next scheduling period.
It should be noted, however, that primary sales information may change during the remaining scheduling periods, depending on market conditions, such as changes in the price of polymer products or raw materials, or changes in required products or quantities of trading companies. Secondary sales information described below is additionally received from the sales staff sales information that is changed in accordance with the above situation changes.
Once the first production information and the first estimated sales information is determined, the first ERP establishment step (S420) determines and manages the inventory by grade of resources for producing the polymer and polymer. To this end, in the first ERP establishment step (S420), the inventory amount of each resource of the polymer and the resource is determined in consideration of the sales performance of the previous scheduling period.
As described above, in the first ERP establishment step (S420), not only the inventory level of each resource is monitored, but also resources can be smoothly produced as scheduled according to the scheduling result determined by the first scheduling step (S440). Actively manage inventory
Then, in the first sales information estimating step (S430), the first initial inventory amount of the next scheduling period is estimated using the production plan for the remaining scheduling period and the sales plan for the remaining scheduling period. At this time, the first initial inventory amount of the next scheduling period may be estimated by adding the inventory subtracted from the production plan during the remaining scheduling period to the inventory amount of the polymer.
The estimated information is reviewed in the first accuracy check step S435. The accuracy checking step S435 checks the accuracy of the determined first production information, the first estimated business information, and the first initial inventory amount of the next scheduling period.
When the primary accuracy checking step S435 is performed, the primary scheduling step S440 schedules the production during the next scheduling period in consideration of the estimated information and the primary estimated business information. As described above, the sales information considered herein may include the sales plan for the remaining scheduling period, and the available amount of the next scheduling period and the next scheduling period.
When the primary scheduling management step (S405) is performed, the production amount and sales amount of the basic polymer can be determined.
As such, when the first scheduling management step S405 is performed during the current scheduling period, the second scheduling management step S455 is performed again at the end of the current scheduling period. However, the second scheduling management step S455 is not necessarily performed only at the end of the current scheduling period. Rather, the second scheduling management step S455 only needs to be performed later than the first scheduling management step S405 and only needs to be performed adjacent to the end of the current scheduling period.
The second scheduling management step (S455), the secondary production information determination step (S450), the secondary sales information determination step (S460), the secondary ERP establishment step (S470), the secondary sales information estimation step (S480), 2 A differential accuracy checking step S485, and a secondary scheduling step S490.
In the second production information determining step S450, the production information is determined again as in the first production information determining step S400. However, since the second production information determination step S450 is performed later than the first production information determination step S400, the production status information for the elapsed period will be increased and the production plan information for the remaining scheduling period will be less. Therefore, the secondary production information, which is the production information determined in the secondary production information determination step S450, may be more accurate than the primary production information determined in the primary production information determination step S400 in determining the final polymer production. .
When the production status of the elapsed period and the production plan for the remaining scheduling period are determined, the second sales information including the sales plan for the remaining scheduling period of the polymer and the available amount of the next scheduling period in the second sales information determination step (S460). Determine. Unlike the first sales information determination step (S410), in the second sales information determination step (S460), only sales information for a forthcoming scheduling period may be determined, and sales information for the next scheduling period may not be determined. In addition, as described above, additional business information such as market conditions, such as a change in the price of a polymer product or a raw material, or a change in a required product or quantity of a trading company is additionally input, which is referred to as second-definition sales information. Accordingly, the second sales information determination step S460 may determine more accurate sales information than the first sales information determination step S410.
Once the secondary production information and the secondary confirmation business information is determined, the secondary ERP establishment step (S470) determines and manages inventory by grade of the resource for producing the polymer and polymer. Similar to the first ERP establishment step (S420), in the second ERP establishment step (S470) in consideration of the sales results of the previous scheduling period determines the inventory amount of each resource of the polymer and resources. In addition, the secondary ERP establishment step (S470) also monitors the inventory amount of each resource grade, as well as inventory the resources so that the production can be made smoothly as scheduled according to the scheduling result determined by the secondary scheduling step (S490). Manage actively
Then, in the second sales information estimating step (S480), the second initial inventory amount of the next scheduling period is reestimated using the production plan for the remaining scheduling period and the sales plan for the remaining scheduling period. At this time, the second initial inventory of the next scheduling period may be estimated by adding the inventory subtracted from the production plan for the remaining scheduling period to the inventory of the polymer.
The estimated information is reviewed in the second accuracy check step S485. The secondary accuracy checking step (S485) checks the accuracy of the determined second production information, the second confirmation business information and the second initial inventory of the next scheduling period.
After the secondary accuracy check step S485, the secondary scheduling step S490 schedules the production during the next scheduling period in consideration of the estimated information and the secondary confirmed business information. As described above, the sales information considered herein may include the sales plan for the remaining scheduling period, and the available amount of the next scheduling period and the next scheduling period.
When the secondary scheduling management step S455 is performed, the final polymer production amount and sales amount may be determined.
Referring back to the drawings, the polymer production scheduling method according to the present invention production information determination step (S400, S450), sales information determination step (S410, S460), ERP establishment step (S420, S470), sales information estimation step (S430) , S480), accuracy checking steps S435 and S485 and scheduling steps S440 and S490 are performed twice. Therefore, it is possible to actively cope with rapid market changes.
5 is a flowchart of a polymer production scheduling method according to another embodiment of the present invention.
In FIG. 5, the polymer production scheduling method includes a first scheduling management step S505 and a second scheduling management step S555. At this time, the first scheduling management step S505 is performed in the middle of the current scheduling period, and the second scheduling management step S555 is performed at the expiration of the current scheduling period.
Similar to FIG. 4, the first scheduling management step S505 includes the first production information determination step S500, the first sales information determination step S510, the first ERP establishment step S520, and the first sales information estimation step. (S530), the first accuracy check step (S535), and the first scheduling step (S540), the second scheduling management step (S555), the second production information determination step (S550), the second sales information determination A step S560, a second ERP establishment step S570, a second sale information estimation step S580, a second accuracy check step S585, and a second scheduling step S590 are included.
Primary production information determination step (S500), primary sales information determination step (S510), secondary production information determination step (S550), secondary sales information determination step (S560) and secondary ERP establishment shown in FIG. Step S570 is similar in operation to the corresponding steps shown in FIG. 4, respectively. Therefore, repetitive description is omitted for simplicity of the specification.
The first ERP establishment step (S520) determines and manages the inventory by grade of the polymer and the resources for producing the polymer. In addition, in the first ERP establishment step (S520), unlike the first ERP establishment step (S420), the inventory amount for each resource of the polymer and the resource is determined by further considering the sales performance and the cost of the previous scheduling period. Therefore, in the primary ERP establishment step (S520), not only the inventory level of each resource grade is monitored, but also the inventory of the resources so that the production can be smoothly performed as scheduled according to the scheduling result determined by the primary scheduling step (S540). Manage actively
In the first sales information estimating step (S530), the first initial inventory amount of the next scheduling period is estimated using the production plan for the remaining scheduling period and the sales plan for the remaining scheduling period. At this time, the estimation method of the initial inventory amount of the next scheduling period is the same as the estimation method of the first sales information estimation step S430 of FIG.
In addition, the primary sales information estimating step (S530) basically estimates the selling price and cost of the next scheduling period and the next scheduling period of the polymer. In this specification, the estimated basic selling price and cost are defined as the first estimated selling price and cost of the next scheduling period and the next scheduling period. As such, the primary sales information estimating step (S530) not only considers the inventory of polymers and resources but also estimates the sales information by considering the cost of each grade and the selling price.
In this case, as described above, the first initial inventory of the next scheduling period may be estimated by subtracting the sales plan for the remaining scheduling period from the production plan for the remaining scheduling period and adding it to the inventory of the polymer. In addition, the selling price of the next scheduling period may be estimated based on the actual selling price and the cost of the previous scheduling period. The reason is that since the current scheduling period has not yet ended, the selling price of the current scheduling period cannot be determined.
However, the present invention is not limited thereto, and it is also described above that the current market price of the polymer and the resources for producing the polymer can also be referred to to determine the selling price and cost of the next scheduling period.
When the primary sales information estimation step S530 is completed, the primary accuracy checking step S535 is performed. In the first accuracy checking step (S535), the accuracy of the determined first production information and the first estimated sales information, the first initial inventory amount of the next scheduling period, and the first estimated selling price and cost of the next scheduling period and the next scheduling period are examined. do.
The first scheduling step S540 schedules the production during the next scheduling period in consideration of the estimated information, the next scheduling period and the selling price and cost of the next scheduling period, and the first estimated business information. The sales information considered here may include the sales plan for the remaining scheduling period, the sales amount of the next scheduling period and the next available scheduling period, and the selling price and cost of the next scheduling period estimated in the first sales information estimating step (S530). Is as described above.
In particular, when producing polymer products, several products are produced sequentially in a single process. Since the product is continuously changed, the off specification has intermediate characteristics before and after the change. Polymer products are produced. Because these products have a lower selling price than genuine products, each process manages and maintains a production sequence to minimize the production of non-genuine polymer products. It will be produced according to.
However, in the first scheduling step (S540) proposed in the present invention, in addition to the selling price and cost of the next and next available sales, the next scheduling period, and the next scheduling period, the (non-genuine) of the polymer product that occurs in each case of product change Because quantity, selling price, and cost can be taken into account, there may be optimal sequence scheduling for scheduling polymer products based on such selling price and cost.
That is, in the first scheduling step (S540), in order to schedule the polymer product to be produced, not only fixed sequence scheduling that schedules the polymer products in a predetermined order, but also the selling price and cost of the genuine and non-genuine polymer products Optimal sequence scheduling considering all of them is also possible.
When the primary scheduling management step S505 is performed, the production amount and sales amount of the basic polymer may be determined.
When the first scheduling management step S505 is performed during the current scheduling period, the second scheduling management step S555 is performed at a subsequent time point in the current scheduling period.
In the second production information determination step S550, the production information is determined again as in the first production information determination step S500. However, since the second production information determination step (S550) is performed later than the first production information determination step (S500), the production status information for the elapsed period is increased and the production plan information for the remaining scheduling period is decreased. As it is. Therefore, the secondary production information, which is the production information determined in the secondary production information determination step (S550), may be more accurate than the primary production information determined in the primary production information determination step (S500) in determining the production amount of the final polymer. .
After the secondary sales information determination step S560 and the second ERP establishment step S570 are performed, the secondary sales information estimation step S580 is performed. Unlike the second sales information estimating step S480 of FIG. 4, the second sales information estimating step S580 of FIG. 5 finally not only sells the second initial inventory amount of the next scheduling period but also sells the unit price and the cost of the next scheduling period. Estimate. In this case, the method of estimating the second initial inventory amount in the next scheduling period is the same as the method of estimating the second sales information in step S480 of FIG. 4, and the unit price and the cost of the next scheduled scheduling period are 2 It is the final selling price and cost.
The estimated information is reviewed in the second accuracy check step S585. In the second accuracy checking step S585, the accuracy of the determined second production information and the second confirmed business information, the second initial stock amount of the next scheduling period, and the second confirmed selling unit price and cost of the next scheduling period are checked.
After the secondary accuracy checking step S585, the secondary scheduling step S590 is performed during the next scheduling period in consideration of the estimated information, the second final sales price and cost of the next scheduling period, and the second final sales information. Scheduling
When the second scheduling management step S555 is performed, the final polymer production amount and sales amount may be determined.
Similar to the polymer production scheduling method shown in FIG. 4, the polymer production scheduling method shown in FIG. 5 also includes production information determination steps S500 and S550, sales information determination steps S510 and S560, and ERP establishment steps S520 and S570. ), The sales information estimating steps S530 and S580, the accuracy checking steps S535 and S585, and the scheduling steps S540 and S590 are performed twice, respectively, to actively cope with sudden market changes. Furthermore, since the polymer production scheduling method shown in FIG. 5 schedules the production in consideration of the selling price and the cost of the next scheduling period, the polymer production scheduling method can increase the polymer production profit in response to the change in the value of the polymer in the market. Has an effect.
