A Fuzzy Approach for Risk Analysis with Application in Project Management

Abstract

A new fuzzy approach is developed for defining the general criticality of activities where some other features such as probability of finishing on time zone, probability of impact, impact threat and ability to retaliate are considered as criticality factors of activities in project management process. In this way the risky situation (vulnerability) of activities are calculated by using fuzzy inference system. Activities are prioritized and classified by means of a fuzzy decision making procedure. The effect of considering such factors on project duration and cost are compared with classic PERT - where only the slack times are considered as criticality factors of activities. The calculated factors of criteria are used for path planning of rescue robot in disaster situations by means of GERT.
