Good project scheduling is an essential yet extremely hard task in software management practice. The time needed to complete a development activity usually is known only roughly. Often, the completion of an activity is delayed due to unanticipated rework. In this paper, we show how process simulation can be utilized in order to support software managers in finding good schedules for their proje...

Good project scheduling is an essential, but extremely hard task in software management practice. In a software project, the time needed to complete some development activity is difficult to estimate. Often, the completion of activities is delayed due to unanticipated rework which is caused by feedback in the process. In this paper, we show how process simulation can be used to support managers...

The earned value technique is a crucial technique in analyzing and controlling the performance of a project which allows a more accurate measurement of both the performance and the progress of a project. This paper presents a new fuzzy-based earned value model with the advantage of developing and analyzing the earned value indices, and the time and the cost estimates at completion under uncerta...

In decentralized construction projects, costs are mostly related to investment, material, holding, logistics, and other minor costs for implementation. For this reason, simultaneous planning of these items and appropriate scheduling of activities can significantly reduce the total costs of the project undertaken. This paper investigates the decentralized multiple construction projects schedulin...

Project preemption allows resources flow passively from one project or task to another. Due to high-cost and high-risk characteristics of software development, project preemption might have a significant impact on the ultimate completion time of a software project. This article examines the feasibility of the Taguchi’s parameter design to achieve robust resource assignment for multiple software...

Some manufacturers impose a time-based contract on their suppliers under which each supplier is paid only when all of the suppliers have completed their tasks. We investigate whether or not the manufacturer ought to demand such a delayed payment contract. In our model with one manufacturer and two suppliers, we compare the impact of both a delayed payment regime and a no delayed payment regime ...

If a public project is Þnanced through private contributions with convex costs, project completion may be delayed. The paper examines how asymmetries, the order of moves, and the absence of commitment will affect the completion time. All three factors are shown to cause delay, although for different reasons. Without commitment, individual contributions are strategic complements in the completin...
