| dc.description.abstract | In the initial stages of a project, apart from defining a clear project scope, project managers and stakeholders care most about the project duration, resources, and costs. However, conventional methods of project scheduling and resource allocation often fail to consider the cross impact of numerous variables, despite considerable amounts of time being spent on planning.
This study created an integer programming model that considers duration limits, work items, resource allocation, remuneration and costs, and other complex factors. This model was then run on general PCs using professional computer software programs to achieve more accurate results in less time than ordinary project scheduling. To validate the feasibility of the proposed mathematical programming model, the digital video recording software development project of a technology company was used as a test case and a two-stage solution was deployed using a proposed model. The results were then compared with those for manual experience–based scheduling. In terms of solution effectiveness and efficiency, this study demonstrated that the solution of test case outperformed that of manual experience–based scheduling. In addition, sensitivity and solution analyses were conducted for project costs, time, and labor resources—factors that are crucial to project stakeholders. The analysis results can assist in the planning process and can facilitate project scheduling.
