Abstract

The invention relates to an optimized scheduling method applied to a distributed production and manufacture process of notebook parts. According to the method, a distributed permutation flow shop scheduling model with limited buffers and an optimization object are determined, and the optimization object are optimized via an optimization method with effective estimation of distribution algorithm. The scheduling model is established according to processing time of each part in different machines, and the object is to minimize the total completion time. According to the invention, effective estimation of distribution algorithm is used to solve a distributed production scheduling problem of the notebook parts, and the EDA based intelligent algorithm is used to solve such type of problems for the first time; an earliest completed factor mapping rule MECF is provided for the first time according to a factory distribution rule ECF, and the problem that distribution information of the parts isdisorganized after local searching of optimal individuals; and the local searching capability of the algorithm is further reinforced via local searching based on Swap and Inverse neighborhood.
