Reworking in developing software exists widely in IT project management. But the current estimating methods on project duration cannot deal well with this problem. In this paper, some key concepts, such as adjusted activity, adjusted GERT network, expected project duration, expected critical path, are firstly defined. Then authors study estimating method on project duration for different rework...

| The reduction of power consumption for a system level pipeline is addressed in this paper. The pipeline is composed of several stages. Each stage has several behaviours. Di erent behaviours have di ering execution times. The speed of the pipeline is only a ected by the behaviours on the critical path of the slowest stages. Other behaviours can be slowed down to decrease the power consumed in ...

Multi-processor scheduling is an NP-hard problem, so heuristic solutions must be found. Several critical path heuristics have been proposed, but these must be empirically tested to see if their solutions are adequate. This paper examines the performance of four critical path heuristics and nds that they are unable to perform well on the types of graphs which are likely to be created by compiler...

A new method for finding fuzzy optimal solution, the maximum total completion fuzzy time and fuzzy critical path for the given fully fuzzy critical path (FFCP) problems using crisp linear programming (LP) problem is proposed. In this proposed method, all the parameters are represented by triangular fuzzy number. The fuzzy optimal solution of the FFCP problems obtained by the proposed method, do...
