Research On Methods For Multiple Object Mould Heat-treatment Shop Floor Batch Scheduling Problem

Mold industry has a very high industrial importance, the level of mold production levels, has become the measure of a country’s manufacturing an important indicator of the level. With the increasingly fierce market competition, rapid pace of product updates, customer delivery punctuality increasingly valued. Also, because the heat treatment is a high energy consumption, high pollution industry and its energy efficiency is low, and energy companies also can not ignore the problem. In the presence of dynamic reach the workpiece and incompatibility situation, taking into account how energy efficiency and punctuality to form a compromise, which is the urgent need to address the problem.In this paper, a large domestic mold manufacturing enterprises as the background, a class of dynamic parallel machine batch transfer issue that weighted tardiness and energy consumption index for the optimization objectives and consider the work dynamic reachability and incompatibility First, the problem describe and propose a class of hybrid scheduling mechanism; followed by the establishment of different mathematical models for different scheduling mechanisms:(1) for event-driven scheduling mechanism, first of all. to build volume weighted tardiness and ineffective energy optimization goals the mathematical model, and propose a heuristic algorithm based on event-driven (TE-LAB); secondly, to verify the algorithm time complexity; finally verify its validity through a lot of simulation experiments and comparative analysis with other rules like algorithm verify its practicality.(2) For flexible cycle scheduling mechanism, first of all, to build a flexible cycle scheduling mechanism; Secondly, TE-LAB algorithm provides the initial solution (EE-GA) is a meta-heuristic algorithm, reuse EE-GA algorithm for optimal solution; last to verify the effectiveness of the algorithm through a large number of simulation experiments. Finally, based on the actual heat treatment shop of the enterprise business processes combined with results of this study, the development of a suitable mold heat treatment workshop production management system that provides decision support for the heat treatment shop managers, and improve its scheduling efficiency and speed.
