Design and Management of Flexible, Electronic Assembly Systems

建立了一个描述大规模装配系统的暂态性能(比假设稳态性能更接近实际)的模型。该模型的计算机运行时间低且负担得起(例如，CPU成本为1.00美元)，而模拟运行的成本(例如，700美元)令人望而却步。该模型基于两个假设，这两个假设在前面的工作中得到了部分验证。本研究的目的之一就是完成验证。如果可以做到这一点，结果应该是一个指导系统设计者开发和评估替代设计的规划过程；一个确保有效材料管理的量化程序；以及一个量化测试/返工策略中所有相关权衡的描述性模型。该方法涉及四项任务。首先是发展操纵模型和减少由近似产生的误差所需的数学。第二是生成一个计算机程序，该程序可以将该模型应用于描述和处方。第三是对工具在实际生产情况下的评估。第四是结果的传播，包括以可用的形式提供计算机程序。

A model has been developed which describes the transient performance (which is more realistic than assuming steady state performance) of large-scale assembly systems. This model has computer run times which are low and affordable (CPU cost of $1.00, for example), compared with prohibitive costs for simulation runs ($700, for example). The model is based on two assumptions, which were partially verified in the preceding work. One purpose of this research is to complete the verification. If this can be done, the result should be a planning process to guide the system designer in developing and evaluating alternative designs; a quantitative procedure to assure effective material management; and a descriptive model that quantifies all relevant trade-offs in test/rework strategies. The approach involves four tasks. First is development of the mathematics required to manipulate the model and to reduce errors resulting from approximations. Second is generation of a computer program that can apply the model for both description and prescription. Third will be evaluation of the tools in actual production situations. Fourth will be dissemination of the results, including making the computer program available in usable form.
