Abstract

Mathematical models of fuzzy time characteristics of operations are proposed. These models are obtained as a result of direct application of the Zadeh extension principle to the critical path method. Based on the decomposition of a graph and selection of essential collections of operations, an efficient method of computation of fuzzy time windows for float times and late start and finish times of operations is developed. The method is illustrated by an example.
