An allocation method of reliability goal for a compact fusion device

Abstract

Currently Southwestern Institute of Physics (SWIP) is performing the conceptual design of a compact fusion device. With the top-level objectives and operation plan determined, the top-level reliability goal has been established. Once the reliability goal is established, the goal must be translated into subsystems or main functions. Currently, there is no relevant literature to study the allocation method suitable for the fusion device systematically. This paper provides an allocation method suitable for the currently designed compact fusion device, namely Analytic Hierarchy Process (AHP), which combines qualitative and quantitative analysis. It uses expert experiences to deeply understand the nature, influencing factors, and internal relationships between complex subsystems. By establishing the hierarchical structure model and constructing the judgment matrix, the distribution weight of each subsystem is given, and the allocation of the reliability goal is completed.
