Abstract

Software evaluation and selection have begun to be addressed as a topic title along with the fact that microcomputers and then personal computers have become widespread and have been used in the operations of businesses. In this study, it was focused on the selection of software for identifying the physical effect distances of the explosion, fire and toxic emission, which is an important need for industrial institutions containing, using or storing hazardous chemicals. The evaluation and selection of software for the hazard analysis and consequence modeling (HACM) of potential accidents was studied at first. In means of methodology, questionnaires consisting of original questions were applied to the experts. With the use of Likert Scale, experts were asked to rate the questions on a level of agreement within the responses. The values obtained from questionnaires according to five-point relative importance Likert scale were aggregated and then converted into Analytical Hierarchy Process (AHP) suggestion matrices. During this process, the weighting assignment process based Likert Scale is used to overcome the inconsistency problem in the pairwise comparison matrices evaluation. As a result, evaluation and selection were made among the HACM softwares.
