Resource-constrained Project Scheduling Approach Under Fuzzy Conditions

This work presents a fuzzy resource-constrained project scheduling problem that is one of the operational research problems that can be defined as a combinatorial NP-hard problem of constructing a special plan for performing a number of precedence related tasks subject to limited uncertain resources. It is relevant to use fuzzy numbers when activity durations rely on human estimations and due to lack of historical data there is no opportunity to predict them accurately. The goal is to construct a fuzzy heuristic-based approach to obtain a near optimal solution in a reasonable computational time.
