An AHP-Fuzzy Complex Evaluation Method for MCR Human Factors Engineering Verification and Validation

Human Factors Engineering (HFE) design of Main Control Room (MCR) is very important to the performance of operators and the operation of Nuclear Power Plants (NPPs). In order to reduce potential human errors, the design of an MCR must consider appropriate human factors. Human factors verification and validation (V&V) evaluations comprehensively determine that the HFE design conforms to HFE design principles. HFE V&V enables plant personnel to successfully perform their tasks to assure plant safety and operational goals. However, in the design verification process, the evaluation of some qualitative design indexes is largely limited by the subjective factors of the tester. In order to improve this deficiency, this paper presents an AHP-fuzzy complex evaluation method based on nuclear industry standard and MCR design experience to assist MCR HFE design verification. The proposed method provides a set of MCR HFE evaluation indexes, the determination of weight factors and fuzzy complex evaluation model. Some preliminary evaluation results are provided and discussed.
