Abstract
Estimation of activity duration is a basic problem for project scheduling. However, the uncertainty of activity duration originates from both probability and fuzziness in the real world. This paper develops a linear programming method with LR type fuzzy numbers, which aims to estimate activity duration and identify critical path, and applies the λ - cut to indicate the degree of optimism of a decision maker. Finally, an example is given to demonstrate the application and validity of the proposed method.
