Allocating resources to a software project and assigning tasks to teams constitute crucial activities that affect project cost and completion time. Finding a solution for such a problem is NP-hard; this requires managers to be supported by proper tools in performing such an allocation. This paper shows how search-based optimization techniques can be combined with a queuing simulation model to a...

In concurrent engineering projects, tasks are usually interdependent among each other that require much iteration before completion where the critical path method/program evaluation and review technique (CPM/PERT) may not be applicable to help estimate the project duration. In addition, carrying out a large-scaled project in a dynamic environment has to deal with various factors at the same tim...

in this paper a network comprising alternative branching nodes with probabilistic outcomes is considered. in other words, network nodes are probabilistic with exclusive-or receiver and exclusive-or emitter. first, an analytical approach is proposed to simplify the structure of network. then, it is assumed that the duration of activities is positive trapezoidal fuzzy number (tfn). this paper com...

naturally all activities are along with risk and uncertainties. project risk has the concept more than the financial concept. in project management, risks are events that can occur during the project implementation and has negative effects on project completion and meeting goals. identification, analysis, prioritizing and having plan for dealing with these events are playing an important role i...

In this chapter we study a team dynamic problem in which a group of agents collaborate over time to complete a project. The project progresses at a rate that depends on the agents’ e↵orts, and it generates a payo↵ upon completion. First, we show that agents work harder the closer the project is to completion, and members of a larger team work harder than members of a smaller team both individua...

OBJECTIVE The purpose of this article is to describe a step-by-step approach to the successful mentorship of trainees completing retrospective radiology research projects. The topics addressed include selection of a mentor and mentee and the selection, planning, initiation, and completion of a retrospective research project. CONCLUSION Mentoring a trainee in the completion of a retrospective ...

I study a dynamic problem in which a group of agents collaborate over time to complete a project. The project progresses at a rate that depends on the agents’ efforts, and it generates a pay-off upon completion. I show that agents work harder the closer the project is to completion, and members of a larger team work harder than members of a smaller team—both individually and on aggregate—if and...

In this paper, we transform a PERT network into a mixtures of truncated exponentials Bayesian network. We use the Shenoy-Shafer architecture to propagate the MTE potentials in the resulting MTE PERT Bayes net and thus to find the marginal distribution of the project completion time. Finding the distribution of the project completion time is important because there is no closed form expression f...
