面向产品生命周期的部分柔性技术选择

Partial Flexible Technology Selection in Product Life-cycle

本文研究随机需求下产品生命周期不同阶段的部分柔性技术选择与生产能力规划问题。部分柔性技术是相对于完全柔性技术而言的,一种生产技术的柔性程度定义为能生产一产品类中产品个数多少的能力。不同柔性强度的生产技术,其投资成本和运行成本不同。本文首先建立了以计划期上总成本最小为目标的技术选择和生产能力规划模型,然后根据产品在其生命周期不同阶段的特点与市场需求的特点,应用所建立的模型进行仿真并总结产品导入期和成熟期技术选择的特点。

This paper concerns the issues of technology selection among different stages of a product′s lifecycle,in an environment characterized by multiple products,multiple periods and random demand.Partial flexible technology,defined as the ability to produce a subset of a product family,its investment and operational cost are highly related to its flexibility.Based on demand scenarios,a mathematical programming model for determining technology selection and capacity planning is developed to minimize the expected total costs;the described model is then applied to analyze the technology selection difference between a product′s introduction stage and mature stage.
