Fire Risk Assessment of PVC Cables Based on Proved Fuzzy-AHP
Evaluating and assessing the fire risk of combustible materials is a very important subject of fire scientific research. Fuzzy evaluation method provides an easy access for comprehensive fire risk assessment, and also avoids the shortcomings in previous methods. But the weights algorithms of judgment matrix suffer from two problems, unsatisfied consistency of judgment matrixes and calculated results instability, which have a significant impact on the results of final assessment. This paper proposes an initiative method based on accelerating genetic algorithm to combines weight calculation with consistency test of judgment matrix, and adjusts the weights of indexes to improve the consistency index approach satisfactorily. On the stability of the calculated results, this paper proposes an improved Fuzzy-AHP method, making stable the computing of weight. The result of data sensitivity analysis shows that the improved method produces stable weight computing. The promising performance of the proposed Fuzzy-AHP method is demonstrated by PVC cable fire risk assessment, and the result can be used for scientific decision.
