Problems solved by technology

[0006] Since the production and assembly line scheduling problem of mobile phones is an NP-hard problem, the traditional mathematical programming method cannot solve the problem. Therefore, the present invention designs an improved adaptive distribution estimation algorithm (Modified AdaptiveEstimation of Distribution Algorithm, MAEDA) optimal scheduling method, which can obtain an excellent solution to the scheduling problem of the production and assembly process of mobile phones in a short period of time.

Abstract

The invention relates to an optimizing scheduling method of a handset in a production assembly process and belongs to the production workshop intelligent optimizing scheduling field. According to the method, a scheduling mode and an optimizing target of the handset in the production assembly process are determined, and an optimizing scheduling method of an improved adaptive distribution evaluation algorithm is utilized to optimize the optimizing target; the scheduling mode is established according to processing time and final assembly completion time of parts of the handset on each machine, and the optimizing target is to minimize the longest completion time. The method makes expression of the production assembly process of the handset be clear and accurate; relatively fine local search on excellent areas searched through global search is carried out, and relatively good balance between the global search and the local search is realized.

Description

technical field [0001] The invention relates to an optimal scheduling method for the production and assembly process of mobile phones, and belongs to the technical field of intelligent optimal scheduling of production workshops. Background technique [0002] At present, domestic auto interior parts production companies have entered the stage of low-profit development. How to produce higher-quality, lower-cost products is related to whether the company can continue to survive. Faced with such a crucial issue, all companies are considering various aspects. There are several countermeasures, and one of the good ways is to try to optimize the production assembly process and shorten the working hours to reduce costs and improve the price competitiveness of products. [0003] In modern mobile phone manufacturing enterprises, the assembly workload accounts for a considerable proportion of the entire product workload, and the technology for producing mobile phones is becoming more a...
