Task parallelism is difficult to implement in a distributed setting due to machine unreliability and communication latency. HTCondor, an existing distributed computation framework, is insufficient for addressing these shortcomings. In this report, we present a high level abstraction built on top of HTCondor called the Distributed Completion Service (DCS). The DCS uses multiple different methods...

When the software projects are developed, in earlier years, many of these projects fails or dropped because of not completion of projects. To resolve these problems and to provide the on-time delivery of project, an effective project plan is required along with project schedule. The project scheduling is effective to achieve the maximum benefit of available resources as well as to control the p...

We present a scheduling model which is tailored to the dynamics of software projects. In the model, activity times are stochastic, resources are constrained and non-identical, and scheduling is preemptive. As opposed to other stochastic project scheduling models, the completion time of an activity explicitly depends on the amount of feedback received from concurrent activities. As a consequence...

We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that the project is completed. The principal pays only on completion of the project. We characterise the co...

In practice, a project usually involves cash inand outflows associated with each activity. This paper aims to minimize the payment failure risk during the project execution for the resource-constrained project scheduling problem (RCPSP). In such models, the money-time value, which is the product of the net cash in-flow and the time length from the completion time of each activity to the project...

Many of the challenges facing the ATM research community are well-known and include substantial technical risk and difficulty demonstrating benefits for stakeholders. To these concerns, we propose to add another: inadequate understanding of the cost and schedule risks of development programs. Of these risks, political influences are particularly difficult to analyze. Political decisions can eff...

This paper addresses the multi-mode multi-skilled resource-constrained project scheduling problem. Activities of real world projects often require more than one skill to be accomplished. Besides, in many real-world situations, the resources are multi-skilled workforces. In presence of multi-skilled resources, it is required to determine the combination of workforces assigned to each activity. H...

Every construction project is always faced with the possibility of problems in project. In reality, implementation projects experiences obstacles that result delays completion work, so time work not accordance plan has been set. Delays occur will cause losses for related parties, especially owners and contractors, because they are generally accompanied by conflicts, demands costs, deviations qu...
