Problems solved by technology

[0003] In the existing technology, the research on production scheduling mainly focuses on the design of the scheduling algorithm, ignoring the improvement of the scheduling model. There is no literature mentioning the decoupling point of the production process, and no literature involves the production The introduction of process decoupling point into the production scheduling research of mass customization

Embodiment Construction

[0025] The following is a systematic detailed description of the production scheduling method based on the location of decoupling points in the PPDP production process.

[0026] 1. The premise of system production scheduling.

[0027] as attached image 3 , the front-end input of the production schedule is the self-made part BOM table, which gives information such as the name and quantity of the self-made part, as well as the production data of the self-made part such as the process card, that is, the content of the bill of material in the system.

[0028] 2. Set up the production process.

[0029] as attached Figure 4 ,, in the production process, fill in all the production processes required in the order production schedule, as well as the processing equipment required for each process and the time required for single-piece processing.

[0030] 3. Set up the part process.

[0031] as attached Figure 5 , select different processing parts from the smallest component, an...

Abstract

The invention provides a production scheduling method based on production process decoupling point positioning. A concept of production process decoupling points is provided. Multi-object positioning models of production process decoupling points are built on the basis of production process analysis. Production scheduling models under an MTO (make to order) production mode and an ATO (assemble to order) production mode according to two positioning positions of production decoupling points, and solving the two types of production scheduling. By the method, personal requirements of customer order can be met, production system dynamic randomness is reduced, scheduling target and production process are simplified, customer requirements are satisfied at short time and low cost, for orders with complex conditions and large number, and scheduling solving results are accurate and effective. The method is wide in application range, high in extensibility, fast in calculation and good in optimal performance.

Description

technical field [0001] The invention relates to a production scheduling method, in particular to a scheduling method under two production modes of MTO and ATO based on production process decoupling point (PPDP) positioning. Background technique [0002] Production scheduling (Production Scheduling) problem, also known as production job planning or production scheduling. From the perspective of limited resources, production scheduling is a decision-making process, which means that the production department arranges the limited resources to complete the order issued by the sales department according to the determined production plan and order delivery schedule, and according to the product processing route. Different jobs, and decide when to start, which equipment to process, and which job to complete, and try to achieve the predetermined goals such as delivery time requirements and improve equipment utilization. These limited resources mainly include: machinery and equipment...
