The Limitation of Free Float and the Introduction of Composite Free Float in CPM Network

Abstract:

This paper analyzes the advantages and disadvantages of the two free float definitions in CPM network. Definition1 is put emphasis on without affecting the immediate succeeding activities; therefore the responding calculation method is simple and regularity. However, the definition1 may not meet the demand of resource leveling optimization. While definition 2 can satisfy the demand of optimization, for it focus on without delaying the successor activities, except the successor dummy activities. But the calculate method of definition 2 is difficult. This paper introduces the new concept of composite free float, absorbing the advantage of two definitions and conquering the disadvantages. So that the new concept not only easy to calculate but also convenient to apply in optimization, meanwhile, it will further be used in studying the generalized precedence network.
