in this paper, we proposed an algorithm for solving the problem of task scheduling using particle swarm optimization algorithm, with changes in the selection and removing the guide and also using the technique to get away from the bad, to move away from local extreme and diversity. scheduling algorithms play an important role in grid computing, parallel tasks scheduling and sending them to appr...

This paper presents a Multi-objective Hyper-heuristic Evolutionary Algorithm (MHypEA) for the solution of Scheduling and Inspection Planning in Software Development Projects. Scheduling and Inspection planning is a vital problem in software engineering whose main objective is to schedule the persons to various activities in the software development process such as coding, inspection, testing an...

  Uncertainty plays a major role in any project evaluation and management process. One of the trickiest parts of any production project work is its cost and time forecasting. Since in the initial phases of production projects uncertainty is at its highest level, a reliable method of project scheduling and cash flow generation is vital to help the managers reach successful implementation of the ...

agricultural mechanization project must be identified in a short time frame to do a certain way; otherwise, cost is not the time to come and will also result in reduced yield. to avoid these costs in farming systems is necessary in any region that agricultural mechanization projects are and scheduling and planning as well as scientific until activities included in the project to fruition are do...

During project execution, especially in a multi-project environment unforeseen events arise that disrupt project plans resulting in deviations of project plans and budgets due to missed due dates and deadlines, resource idleness, higher work-in-process inventory and increased system nervousness. Therefore, project schedules should also include solution robustness to cope with the uncertainties ...

nowadays organization especially r&d; centers are dealing with project portfolio selection decisions under uncertainty. moreover in the most of the past research, project portfolio selection and scheduling are often considered to be independent problem. this leads to insufficient result in real world. so in this research simultaneous project portfolio selection and scheduling problem is modelin...

This is the second part of a paper considering the multi-mode resource-constrained project scheduling problem. The rst part presents an exact solution procedure for solving several variants of the multi-mode resource-constrained project scheduling problem including the commonly known makespan minimization problem. The basic scheme is enhanced by powerful search tree reduction schemes considerab...
