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

该项目是一个探索性的一步， 方法，以帮助设计的可维护性， 计算机集成制造系统。 将研究 维护停机时间和故障诊断的根本原因 计算机集成生产系统的困难。 该项目 两个组成部分。 首先是收集和分析 基于工厂的现场数据， 各种故障，包括频率信息， 故障和每次故障的停机时间。 第二部件 是一项实验性的研究， 很难诊断。 实验研究将利用 专业的故障诊断仪，以诊断故障的计算机为基础的 制造单元的过程控制模型。

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.
