Reliability Analysis of the Proposed Hierarchical Computer Control System for Large Steel Manufacturing Complexes,

摘要

The proposed hierarchical computer control system is an interconnected network of computers/controllers designed to coordinate and operate a large steel production complex. This report demonstrates how reliability/availability analysis is used to assist in the design of the control system. In a brief description of the control system the hierarchy,interconnections,redundancy,the main computer,other computers,and consoles are discussed. The GRASP simulation program and its application to U.S. Steel's computer system is summarized. An assessment of component failure and repair characteristics of the system is made,and results of the reliability analysis of the control system are presented. Two programs are presented in the appendices: (1) Disc Analysis Program;and (2) GRASP Program Data for Model 8. (Portions of this document are not fully legible)
