Fig. 1 is a flowchart of a contract set batch production control method provided by an embodiment of the present invention, and as shown in fig. 1, the method includes:
step 101, determining production parameters of contract batch production in a target month.
In this embodiment, the production parameters include the type and number of contracts that need to be produced in batches by the whole plant in the target month, the monthly maintenance schedule of each step of the whole flow of the target month, and historical production data in a set time period before the target month.
For example, the types of the contracts are the types of materials requiring processing, for example, the types of the contracts are cold rolling contracts, and the cold rolling contracts may include materials such as automobile outer panels, high strength steel (DP steel), low alloy steel, zinc-aluminum-magnesium layers, aluminum-silicon-plated layers, and aluminum-zinc-magnesium layers. The amount of the contract is the amount of material to be processed, such as the number of materials or the weight of the materials.
For example, the monthly service plan may include a service date and a service time period of each process, that is, a service date and a service time period of the processing machine corresponding to each process.
For example, the historical production data may include the type and amount of each material actually processed and produced each month, and the execution sequence and production cycle of each corresponding process. Historical production data in a set time period before the target month are stored and can be obtained by calling. The set time period can be freely selected according to needs. For example, historical production data for 6 or 12 months prior to the target month may be selected.
In an implementation manner of this embodiment, a special attribute contract classification definition base table may be created, and the multidimensional definition requires batch production of contracts. And automatically extracting the contract quantity and the historical production data of the target month. And the contract structure and the number of the multi-dimensional set batch production are compared transversely and longitudinally.
And 102, determining a production plan of contract set batch production in the target month according to the production parameters.
The production plan comprises the execution sequence of all the procedures in the whole flow, the production period of all the procedures and the material preparation date of all the procedures.
In this embodiment, step S102 may include:
the method comprises the following steps of firstly, determining the execution sequence of each procedure and the production cycle of each procedure of the whole flow of a target month according to historical production data and the types and the number of contracts.
And secondly, determining the material preparation date of the last procedure according to the historical production data and the types and the number of contracts.
Specifically, the production plan of the historical month in which the type and quantity of each material actually processed and produced is the same as or similar to the type and quantity of the contract to be processed in the target month may be referred to, so as to determine the execution sequence of each procedure in the full flow of the target month, the production cycle of each procedure, and the material preparation date of the last procedure according to the production plan of the historical month.
And thirdly, determining the material preparation dates of other processes except the last process according to the material preparation date of the last process, the production period of each process and the monthly maintenance plan.
Specifically, the third step may include:
coding the material preparation date of the last procedure according to a set coding rule to obtain a first code;
respectively sending the first codes to other processes except the last process;
and other processes determine the material preparation time of the last process according to the first code, and respectively reverse the material preparation time of each process according to the production cycle of each process, the overhaul date and the overhaul duration of each process.
In this embodiment, the encoding may be performed according to the arrangement order of the first field, the second field, the third field, and the fourth field. The first field is the code of each process, the second field is the material preparation date of each process, the third field is the batch reason code of the contract, and the fourth field is the number of the contract.
Specifically, the first field may include two bytes, the second field may include four bytes, i.e., month 2 bits + day 2 bits, the second field may include three bytes, and the fourth field may include three or four bytes, and the intra-system delivery is realized by coding information.
For example, in the present embodiment, taking a cold rolling contract of the type of galvanized automobile outer panel as an example, the working totally includes four steps: steel making, hot rolling, acid rolling and hot galvanizing. When the first field is a steel-making process, the corresponding code can be represented by A5/A6/A7; when the first field is a hot rolling process, the corresponding code can be represented by H5/H6/H8; when the first field is the acid rolling process, the corresponding SA/SB/SC code can be adopted for representation; when the first field is a hot galvanizing process, the corresponding DA/DB/DD/DE/DK/DG code can be adopted for representation.
The batch reason is the kind of contract. For example, the batch reasons for a cold rolling contract may include, for example: the steel plate comprises an automobile outer plate, a zinc-aluminum-magnesium coating, an aluminum-silicon coating, an aluminum-zinc coating, high-strength steel (DP steel) and low alloy, wherein the corresponding codes are WB, ZM, AS, AZ, DP and LA respectively.
It should be noted that the above encoding method is only an example, and the present invention includes but is not limited thereto.
Optionally, the first code may be transmitted to a production planning, production planning management and operation department inventory management interface of each process of the whole flow.
Specifically, the information transmission of the batch contract in the plan scheduling interface and the plan management interface of each upstream process in the whole process in the system comprises five processes including a material application process, a steel making process, a hot rolling process, an acid continuous rolling process and a cold rolling process. Therefore, each process planner can see the time node required by the last process set batch in the first time of scheduling, and the situation that the production cost of the next process is increased or the batch contract is finished due to the fact that the latest preparation period of the process and the last set batch production date are missed because information is omitted when work is handed over between planners outside the system is avoided.
The method establishes the production plan of the procedure set batch contract at the end of the current month by summarizing the characteristics of the historical contract set batch plan, combining the structure and the quantity of the current month set batch contract and referring to the monthly maintenance plan.
Optionally, the method may further include:
the method comprises the steps of firstly, judging whether the contracts needing batch production in a target month have various production plans, wherein the contracts can be produced among a plurality of parallel working procedures in the various production plans.
If yes, calculating the preparation date of the whole process. If not, calculating the ready date of the process under the current process route.
And secondly, judging whether the material preparation date of each process in various production plans meets the date requirement or not.
In this embodiment, the material preparation date T of the last process in each production plan can be judged i Whether or not at the earliest prepared date T mix And latest ready date T max In between.
Wherein the earliest prepared date T mix The latest preparation date T is the preparation date of the material processed by all the procedures in the whole process from the current date max A date of delivery specified for the contract.
If Ti ∈ (Tmix, Tmax), namely the prepared date of the current process is between the earliest prepared date and the latest prepared date, the system automatically calculates the prepared date of the whole process, and simultaneously, the batch date and the batch reason code of each process set can be synchronously transmitted to each process scheduling interface and each inventory management interface.
If it is
That is, the prepared date of the current process is earlier than the earliest prepared date or later than the latest prepared date, at this time, the prepared date of the process cannot be met in the actual organization production, error information needs to be prompted, and then the planning personnel resets the final process set batch date.
And thirdly, selecting a production plan with the material preparation date of each process meeting the date requirement as a final production plan.
In this embodiment, each process integration planner can review whether the currently determined production plan is feasible.

Through monitoring of two main lines of contracts and materials, the node arrival rate of each procedure is improved. This process is the C-phase operation of the PDCA cycle.
And then, acquiring analysis statistics of reasons for incompletion of the contract of the 3# hot-galvanized automobile outer panel by means of a system platform, analyzing historical data according to incompletion actual results of the contract of the 3# hot-galvanized automobile outer panel, and using a pareto chart to concentrate main efforts to attack 20% of problem points by adopting a twenty-eight rule so as to solve 80% of problems. This process is the operation of the A phase of the PDCA cycle.
