Embodiment
Fig. 1 is the hardware structure figure of production schedule automatic arrangement program of the present invention system preferred embodiment.This system mainly comprises main frame 10 and the database 30 that is connected with main frame 10.
The description of the goods that database 30 stores the order data, begun to put into production (work in process, WIP), production capacity deploying situation, month shipment plan of needs table and the material at each worker station advances data such as factory's planning chart on the production line.Wherein, the order data comprises friendship phase, the client of each order, the kind of order goods, the quantity of order demand, finish the related task of order (feed intake, cut, gum is fitted ... assembling, warehouse-in), the worker station that need pass through of each task, task be through the sequential scheduling information at worker station.Production capacity is meant production equipment fertile product quantity in the regular hour.The production capacity deploying situation at each worker station comprises average production capacity, the maximum production capacity at each worker station, and the board quantity that each worker station comprises, reaches production capacity deploying information that each worker stands every day etc. at the fixedly production capacity of each board, working time.Month shipment plan of needs table comprises the plan information that dispatches from the factory of all goods in certain in January, as shipment date, shipping Qty. etc.What material advanced material that factory's planning chart comprises that various goods are related advances factory's plan information, as advances factory's date, quantity etc.
Described main frame 10 also is connected with display 20, keyboard 40 and mouse 50.Keyboard 40 and mouse 50 are being provided with calendar data and scheduling parameter input data for the user.Display 20 provides a display interface to browse above-mentioned various data and data that scheduling produced for the user.
Described main frame 10 comprises that data read module 110, parameter are provided with module 120 and production schedule arranging module 130.
Parameter is provided with module 120 and is used for calendar being set and the scheduling parameter being set for the user.Calendar wherein being set being meant normal workday and the overtime that each worker station is set, can be that unit is provided with calendar for unit or with the month in week.The scheduling parameter is set comprises the priority level of setting the order scheduling.The scheduling parameter is set comprises being arranged on whether consider current WIP inventories in the follow-up scheduling process.The WIP stock is meant the quantity that the goods of order has put into production, if consider current WIP stock, then in follow-up scheduling process, the quantity required of respective orders should be reduced current WIP stockpile number.
Production schedule arranging module 130 is used for carrying out production schedule scheduling automatically according to the multiple restrictive conditions such as priority orders that described month shipment demand information, material advance factory's plan information and set the order scheduling, and the task that each order is related is assigned to each worker station according to the production capacity situation at each worker station.
As shown in Figure 2, be the process flow diagram of production schedule automatic arrangement program method of the present invention preferred embodiment.At first, in step S10, data read module 110 accessing databases 30 read the production capacity data at each worker station of the order data that need carry out production scheduling and enterprises from database 30.Wherein, the order data comprises friendship phase, the client of order, the kind of order goods, the quantity of order demand, finish the related task of order (feed intake, cut, gum is fitted ... assembling, warehouse-in), the worker station that need pass through of each task, task be through the sequential scheduling information at worker station; The production capacity data at each worker station comprises average production capacity, the maximum production capacity at each worker station, and the board quantity that each worker station comprises, reaches the information such as production capacity deploying that each worker stands every day at the fixedly production capacity of each board, working time.
Next, in step S12, data read module 110 accessing databases 30 read a moon shipment plan of needs table from database 30, obtain the shipment plan information of of that month all goods.In general, " first shipment is produced earlier " is one of main principle of production schedule deploying.
Further, in step S14, data read module 110 accessing databases 30 read material and advance factory's planning chart from database 30, and that obtains the related material of each order advances the factory situation condition." material first in first out " also is the main principle of production schedule deploying, if two order A are identical with the plan shipment date of B, but the advanced factory of the processing starting material of order B then earlier carries out production schedule scheduling to order B.
In step S16, the user is provided with the layout setting calendar that module 120 provides by parameter, and promptly be set the normal workday and the overtime at each worker station.Calendar setting can be a unit for unit or month in week, if be that unit then is provided with normal workday and the overtime in the week with the week; If with the month is that unit then is provided with normal workday and the overtime in certain January.
Calendar after setting completed, in step S18, the user is provided with the layout setting scheduling parameter (as shown in Figure 3) that module 120 provides by parameter, described scheduling parameter comprises the priority level of setting the order scheduling, as sets the fate in advance (as shipment time in advance be 1 day) of certain work station of a certain order.Advance under the identical situation of factory's time at each order shipment date and material in the original plan, according to the production schedule of each order of priority level deploying of the order that sets.Further, in step S20, the user judges whether the parameter setting considers the WIP Inventory Performance.The WIP stock is meant the quantity that the goods of order has put into production.If do not consider the WIP Inventory Performance, then directly enter step S24, the multiple restrictive conditions such as priority orders that production schedule arranging module 130 is advanced factory's plan information according to described month shipment demand information, material and set the order scheduling carry out production schedule scheduling automatically, and the task that each order is related is assigned to each worker station according to the production capacity situation at each worker station.
If be the current WIP stock of consideration in step S20 user judged result, then enter step S22, data read module 110 accessing databases 30, the WIP inventory information of current each goods of inquiry, production schedule arranging module 130 should be reduced current WIP stockpile number with the quantity required of respective orders; Afterwards, flow process enters step S24.
