并行工程中面向多目标的目标决策方案

Multiobjective Coordination Approach in Concurrent Engineering

目标决策(Goal programming,GP)是一种常用的多目标分析管理技术。在实施并行工程（Concurrent engineering,CE)期间结合目标决策技术能够很好地协调工程中多个目标间的冲突。如何压缩产品开发时间和降低耗费一直是生产中决策者关心的问题。文中采用目标决策的方法，引入了ＧＰ／ＣＥ数学模型，针对产品并行开发中耗资与耗时两个相冲突的目标，对产品并行开发的过程进行ＧＰ／ＣＥ模型建摸，达到优化并行工程的实施效果。

How to balance and coordinate different conflicting objects in concurrent engineering (CE) has long been a disturbance in manufacturing industry. Goal programming (GP) is a commonly used engineering and management technique to improve decision making by conflicting objectives criteria. The conflicting objectives can be harmonized when using GP as an aid to CE in new product development. In the practical situation, reducing both cost and time tolerance has always been an interesting area for the decision maker. This paper shows how to construct GP/CE model using GP technology in CE process according to the double conflicting objectives──cost and time,to enhance the performance of CE. A simple and effective methodology algorithm for the problem is presented to generate efficient solutions with respect to cost and time.
