We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...

Earned Value Management (EVM) is a method used to monitor and predict project completion time. This uses linear approach in predicting time completion. Unfortunately, most of the projects run dynamic environments with complex characteristics, causing progress require non-linear approach. That why use EVM monitoring less effective. study proposes more realistic alternative using non-Linear based...

In this study, we aim to present a new model for the resource-constrained project scheduling problem (RCPSP) considering a working calendar for project members and determined the skill factor of any member using the efficiency concept. For this purpose, the recyclable resources are staff resources where any person with multiple skills can meet the required skills of activities in a given time. ...

Rigorous and automatable approaches to software process measurement are a technology essential for supporting decision makers, such as project managers, in obtaining reliable estimations of relevant properties of the development project and in controlling it. We introduce a methodology, called Propean (Project Performance Analysis), which applies classical techniques of performance analysis to ...

In this paper, a preemptive multi-objective multi-mode project scheduling model for resource investment problem is proposed. The first objective function is to minimize the completion time of project (makespan);the second objective function is to minimize the cost of using renewable resources. Non-renewable resources are also considered as parameters in this model. The preemption of activities ...

This paper seeks to add contributions of the innovation and industrial Economics to more used techniques of crashing, in the Projects Management domain. First, it presents the brute force method, improved for the use of the MSProject. Second, it develops a linear program approaches for determining the earliest crash completion time and for determining a least costly crash schedule, for the same...
