In this paper we review different approaches for scheduling projects in multi-project environments. We show the evolution of the methodologies from the Resource Constrained Project Scheduling Problem to the Decentralized Resource Constrained Multi-Project Scheduling Problem. We argue that traditional methods used in project scheduling cannot cope with the complexity of current real portfolios p...

Managing multiple project is a complex task involving the unrelenting pressures of time and cost. Many studies have proposed various tools and techniques for single-project scheduling; however, the literature further considering multimode or multiproject issues occurring in the real world is rather scarce. In this paper, design structure matrix DSM and an improved artificial immune network algo...

Fuzzy project scheduling has interested several researchers in the past two decades; about 20 articles have been written on this issue. Contrary to stochastic project-scheduling approaches that are used by many project schedulers, and even if the axiomatic associated to the theory of probabilities is not always compatible with decision-making situations, fuzzy project-scheduling approaches that...

one of the important problems in project management is lack of available resources in proper time at project site that leads to lack of project implementation in due date. this problem may be lead to time delay in sending resources from suppliers and related origins in supply chain to project site. therfore, to better resources managmenet and also the improvement of supply chain condition, the ...

Dynamic, adaptive, real-time embedded control systems are present at any level(s) of an enterprise— e.g., devices in the defense domain such as multi-mode phased array radars and battle management. These embedded systems often include“soft”as well as“hard” time constraints. Jensen’s time/utility functions [4] (or TUFs) allow the semantics of soft time constraints to be precisely specified. A TU...

In project scheduling, the durations of activities are often uncertain. Delays may cause a massive disorganization if large number must be rescheduled. “The Anchor-Robust Project Scheduling Problem,” Bendotti, Chrétienne, Fouilhoux, and Pass-Lanneau propose novel criterion for solution stability in scheduling under processing times uncertainty. They define anchored jobs as whose starting can gu...
