The DYLAM Approach to Systems Safety and Reliability Assessment

A SURVEY OF THE PRINCIPAL FEATURES AND APPLICATIONS OF DYLAM (DYNAMIC LOGICAL ANALYTICAL METHODOLOGY) IS PRESENTED, WHOSE BASIC PRINCIPLES CAN BE SUMMARIZED AS FOLLOWS: AFTER A PARTICULAR MODELLING OF THE COMPONENT STATES, COMPUTERIZED HEURISTICAL PROCEDURES GENERATE STOCHASTIC CONFIGURATIONS OF THE SYSTEM, WHEREAS THE RESULTING PHYSICAL PROCESSES ARE SIMULTANEOUSLY SIMULATED TO GIVE ACCOUNT OF THE POSSIBLE INTERACTIONS BETWEEN PHYSICS AND STATES, AND, ON THE OTHER HAND, TO SEARCH FOR SYSTEM DANGEROUS CONFIGURATIONS AND RELATED PROBABILITIES. THE ASSOCIATION OF PROBABILISTIC TECHNIQUES FOR DESCRIBING THE STATES WITH PHYSICAL EQUATIONS FOR DESCRIBING THE PROCESS RESULTS IN A VERY POWERFUL TOOL FOR SAFETY AND RELIABILITY ASSESSMENT OF SYSTEMS POTENTIALLY SUBJECTED TO DANGEROUS INCIDENTAL TRANSIENTS. A COMPREHENSIVE PICTURE OF DYLAM CAPABILITY FOR MANIFOLD APPLICATIONS CAN BE OBTAINED BY THE REVIEW OF THE STUDY CASES ANALYSED (LMFBR CORE ACCIDENT, SYSTEMS RELIABILITY ASSESSMENT, ACCIDENT SIMULATION, MAN-MACHINE INTERACTION ANALYSIS, CHEMICAL REACTORS SAFETY, ETC.).
