Abstract

Failure Modes and Effect analysis (FMEA) is a widely used technique for inductive safety analysis. FMEA provides engineers with valuable information about failure modes of system components as well as procedures for error detection and recovery. In this paper we propose an approach that facilitates representation of FMEA results in formal Event-B specifications of control systems. We define a number of patterns for representing requirements derived from FMEA in formal system model in Event-B. The patterns help the developers to trace the requirements and allow them to increase automation of formal system development by refinement. Our approach is illustrated by an example - a sluice system.
