The production plan method based on limited capacity and the simulation system have the advantages of greatly enhanced scientificity and accuracy, high practicality, strong adaptability and high work efficiency.

Description

technical field [0001] The invention relates to the field of aero-engine manufacturing, in particular to a production planning method based on limited capacity and a simulation system thereof. Background technique [0002] The various types of housing parts of the aero-engine fuel regulation control system have complex structures and high precision requirements. During the production and processing of the housings of these regulation control systems, they have always been the key link that restricts the scientific research and production of the aero-engine fuel regulation control system. These casings The body line production method mainly adopts the method of manual overall planning. Although this method can largely meet the shell production of the aero-engine fuel regulation control system in a certain period of time, it also has the following disadvantages: [0003] 1. Poor accuracy and scientificity. [0004] Using the method of manual overall planning to produce this k...

AI Technical Summary

Problems solved by technology

[0003] 1. Poor accuracy and scientific quality

[0004] Using the method of manual overall planning to produce this kind of shell, the shell itself cannot be balanced and comprehensive, and there are many types of parts, which cannot be exhaustive. Only the most important components can be considered for production scheduling; and this method mainly relies on the long-term human resources. Accumulated work experience is carried out, seriously lacking in accuracy and scientificity

[0005] 2. Poor adaptability

[0006] The manual overall planning production method cannot achieve fast rolling, because the quality of various shells of the aero-engine fuel regulation control system produced according to it is unstable, and the product batch is small, which belongs to the typical multi-variety and small-batch production mode. It will soon be unable to keep up with the corresponding changes in production demand, and at this time the original production method will lose the role of the original plan to a large extent, and the production method needs to be re-established

The original production method cannot be well adapted to the new shell production, and the adaptability is relatively poor

[0007] 3. Low work efficiency, time-consuming and labor-intensive, high cost

[0008] Due to the large variety of various types of shells of the aero-engine fuel adjustment control system, the production methods and production organization are extensive, the information communication is not smooth, and the implementability of the plan is very poor.

The production organization is that the production section arranges production according to the weekly plan. In actual production, it often cannot be executed according to the plan, and the randomness is relatively large.

Production coordination is mainly through weekly meetings, meetings, oral communication, etc.; these methods are a waste of time, and the effect is very poor, and the work efficiency is seriously low

Moreover, when this method is used to produce the housing, the planning of key parts will take at least a few days to complete, and rapid response cannot be achieved. Moreover, due to lack of scientific optimization, parts are often delayed, and the utilization rate of production equipment is low, resulting in a large manufacturing cost of parts. Increase, time-consuming and laborious work

[0009] With the advancement of science and technology, some production methods have appeared on the market, but this method is based on the method of production scheduling. They mainly use genetic, artificial neural network, mathematical programming and other algorithms for overall planning, and these algorithms are NP-Hard. (Non-deterministic problems with polynomial complexity) problems cannot obtain complex optimal solutions, and the calculation time is very long, which cannot be applied to actual scheduling production
