Management-Control Integration for Safety-Critical Integration for Safety-Critical Discrete Operation System

Abstract

The safety-critical discrete operation system is safety-critical, discrete and flow driven. The application of dispatching command system and process control system reduces the work intensity. However, information isolation and human operation may lead to insecurity, inefficiency and high cost. In order to ensure production safety, reduce attrition and increase efficiency, firstly, based on the unified multi-dimensional information integration platform, a broader safety-critical management-control integration (SCMCI) theory was put forward. Then, the hierarchical information interlocking (HII) model of SCMCI was established. Finally, the principles, rules and constraints of SCMCI model were proposed. SCMCI technology can realize automatic management of operation planning, automatic execution of control system, and automatic feedback of execution status. The SCMCI technology has been used in production operations management of metro rolling stock base to validate the feasibility of structure, model and algorithm.
