Approach to Implementing Health and Environmental Safety System in Construction Projects Using Fuzzy Logic

Abstract

The present study's objective is the implementation of the general Health and Safety Executive(HSE) Plan in civil projects; at first, it is required to formulate the Work Breakdown Structure(WBS) in the relevant project with the aim of coming to a proper time plan. In this study, the scope of the implementation of this system includes two items in which the probability and risks of timing projects can come to light.The two substantial items in timing projects are activity and time itself which, in some projects, given the un-clarity of the scope of these two items, one is required to take into consideration the probable and approximate value of such scope with the analysis of the fuzzy expert method. And, one of the methods used for the analysis of the scope of timing probabilities is the use of the practical implications of fuzzy logic in engineering sciences; thus, in the essay at hand, the basic information required for risk assessment, fuzzy logic, the theory of fuzzy numbers, and the method used for analyzing, disintegrating, and composing them, with the purpose of applying them in projects' risk assessment, is presented.Fuzzy logic can be introduced as a powerful and flexible tool for analyzing the scope of risk of projects which is enabled to provide us with the mathematical formulation of the unclear or unspecific parameters and, eventually, represent the analysis and evaluation of data in a numerical format.
