Solving Fuzzy Critical Path Problems Through R Software

A crucial tool for the planning and management of complicated and large-scale projects is the critical path method (CPM). A precise estimate of the period will be necessary for the CPM to be implemented successfully. However, in actuality, the length of time cannot be precisely calculated. Because of this, there is never a guarantee on how long tasks will take, which prompts the creation of the fuzzy critical path technique. Using software to solve problems has several benefits, including: (1) Reducing time complexity. (2) It enables us to resolve challenging issues. In this article two R software packages FuzzyNumbers and critpath are applied to develop an algorithm for solving fuzzy critical path problems.
