Construction AHP Safety Comprehensive Evaluation

Construction AHP comprehensive evaluation is the Analytic Hierarchy Process in the field of construction safety an important application. Based on the construction of a major injury accident Fault Tree Analysis (high -altitude crash incident as an example), a comprehensive understanding of the cause of the accident, the basic factors, and then through the AHP these basic factors of weight calculation shows that the accident occurred in their relative importance in the final combined with mathematical methods are subjective evaluation factors from the way a comprehensive evaluation. Construction safety AHP comprehensive evaluation takes full account of man, machine and environment of three factors, combined with the subjective and objective evaluation of the merits, is a relatively comprehensive and effective evaluation methods. AHP comprehensive safety evaluation is to determine the key factors affecting the accident occurred weights, thereby judgment matrix structure, which is based on a thorough analysis of the incident on the basis of. Construction of a major injury accident Fault Tree Analysis, understanding the causes of the accident. Using Boolean algebra tree for simplification of the accident and make equivalent map, making impact on the root causes of the accident clearly. The accident affected by many factors, and some factors have a more or less logical links, and some are among factors still exist in sequence. In the incident on Fault Tree Analysis, these factors impact on the accident, the surface will be different categories, the relative importance of which can also be corresponding know. After this analysis down, the key to control of the accident is not hard to see the point. The traditional evaluation models are generally made vague, general evaluation, and comprehensive evaluation AHP has a clear purpose, its security system against the existence of various factors accordingly informed analysis, combining people, machinery and environment three factors, which can be made effective, comprehensive evaluation. In this regard isthetraditional evaluation method can not and, therefore, that AHP comprehensive safety evaluation of the evaluation is a well-established pattern.
