Abstract

The invention discloses a reliability assessment method of a DCS system. The method comprises the steps of conducting a computing process according to an equipment reliability score corresponding to asub-system, obtained sub-system assessment data and recorded sub-system objective data to obtain a sub-system reliability score, wherein the equipment reliability score is obtained through a computing process according to obtained equipment assessment data and recorded equipment objective data; conducting a DCS assessment computing process according to all the sub-system reliability score and weight coefficients to obtain a DCS system reliability score. According to the reliability assessment method of the DCS system, the reliability assessment score of the DCS system is computed by dividingthe DCS system into three levels of equipment, the sub-system and a total system, and reliability assessment of the DCS system is achieved. The invention further discloses a reliability assessment device, a server and a computer readable storage medium, wherein the reliability assessment device, the server and the computer readable storage medium have the advantages.

Description

technical field [0001] The present application relates to quantitative analysis technology, and in particular to a DCS system reliability assessment method, reliability assessment device, server and computer-readable storage medium. Background technique [0002] Distributed control system is referred to as DCS system, and it can also be translated literally as "distributed control system" or "distributed computer control system". The distributed control system is an instrument control system based on the microprocessor, which adopts the design principles of decentralized control functions, centralized display and operation, taking into account the design principles of division and autonomy and comprehensive coordination. The DCS system mainly adopts the basic design concept of decentralized control, centralized operation and management, and adopts a structural form of multi-layer classification and cooperation and autonomy. The main features are centralized management and d...
