生产系统的多目标分析与优化

摘要

随着产业结构的调整,我国成为全球制造中心的趋势将越来越明显，但作为一个“劳动密集型”为主的国家，我国人均劳动生产率和产品合格率与国外相比存在着较大的差距。本文正是在这种背景下，结合系统工程、基础工业工程、人因工程、运筹学等学科的理论和方法展开研究的。

本文以天津耀华机械厂生产系统为研究对象，首先，利用系统工程的的方法对生产系统中生产效率、作业环境、成本、产品质量、安全多个目标进行分析，根据分析结果建立影响生产系统效率因素的结构模型图。其次，对影响生产系统因素运用层次分析法，对各因素进行排序，找出主要问题因素。最后，运用工业工程和人因工程学中的方法（如方法研究）对生产系统进行改善，得出改善结果，并进行改善后的评价，得到一个最优、满意、高效的生产系统。

Abstract

With the adjustment of industrial structure, China has become the world's manufacturing center of the trend will become increasingly evident, but as a "labor-intensive" based country, China's per capita labor productivity and product qualification rate compared with other countries there are large gap. This article is in this context that combines systems engineering, basic industrial engineering, human factors engineering, operations research and other disciplines, theories and methods for Research.

In this paper, Tianjin Yaohua machinery factory production system as the research object, first of all, the use of systems engineering approach to production efficiency production system, operating environment, cost, product quality, safety analysis of multiple targets, according to the results of the analysis to establish affecting production systems efficiency factor structural model diagram. Secondly, the factors affecting the production system using AHP to sort the various factors to identify key issues factor. Finally, the use of industrial engineering and human factors engineering methods in (such as a method of) the improvement of the production system, to improve the results obtained, and make improvements after evaluation, to get an optimal and satisfactory and efficient production systems.

Keywords: production systems; multi-objective; systems engineering; AHP; Methods
