An Efficient Approach for Fuzzy Project Network Analysis

1　 IntroductionProject network analysis is a successful instrument in the planning and control of large,complex project.A network G( N,A) is a picture of a project with node set N and arc setA.The network representing the project is acyclic,compact and directed.The nodesstand for the events,while the arcs stand for the activities of the project.Each activity isdefined as a task requiring time for its completion,and each event represents a point intime that signifies the completion of some …

An Efficient Approach for Fuzzy Project Network Analysis

In this paper we present two-level linear programming method for determining latest dates and slack times in project network models with triangular fuzzy number or trapezoidal fuzzy number. Compared with the well-known fuzzy network techniques in literature, the approach always produces the meaningful latest dates and slack times. Practically we have generalized critical path method by accepting imprecise, fuzzy data for the duration of the activities.
