Investigating Causes of Maintenance Downtime and Trouble- shooting Difficulty in Computer-Integrated Production Systems

该项目是开发新方法的探索性步骤，以帮助设计计算机集成制造系统的可维护性。它将研究计算机集成生产系统中维护停机和故障诊断困难的根本来源。该项目有两个组成部分。第一个涉及收集和分析与各种故障相关的停机时间量的基于工厂的现场数据，包括有关故障频率和每次故障的停机时间的信息。第二部分是一项实验研究，以了解是什么原因导致这些故障难以诊断。这项实验研究将利用专业的故障排除人员来诊断基于计算机的制造单元过程控制模型中的故障。

This project is an exploratory step into the development of new methodologies to aid in the design for maintainability of computer-integrated manufacturing systems. It will study the underlying sources of maintenance downtime and fault diagnosis difficulty in computer-integrated production systems. The project has two components. The first involves collecting and analyzing plant-based field data on the amount of downtime associated with various kinds of failures, including information on frequency of failures and the amount of downtime per failue. The second component is an experimental study to understand what makes these failures difficult to diagnose. The experimental study will utilize professional troubleshooters to diagnose faults in a computer-based model of the process control of a manufacturing cell.
