A mathematical model for crashing projects by considering time, cost, quality and risk

The present study also considers the impact of risks, which is highly applicable in projects with a high level of uncertainty. Results are presented using integer programming approach with the aim of minimizing the costs of the project. | A mathematical model for crashing projects by considering time cost quality and risk Journal of Project Management 2 2017 27 36 Contents lists available at GrowingScience Journal of Project Management homepage A mathematical model for crashing projects by considering time cost quality and risk Amin Mahmoudia and Mohammad Reza Feylizadeha a Department of Industrial Engineering Shiraz Branch Islamic Azad University Shiraz Iran CHRONICLE ABSTRACT Article history Employers are looking for reducing execution time and maintaining the quality of the projects Received March 5 2017 that are the main objective of the projects.

For the proposed integer linear 16 2017 model cost of conformance and cost of non-conformance are considered as parts of the costs of Accepted July 15 2017 Available online quality of deliverables in projects. The cost of conformance consists of the costs of training the July 15 2017 project team inspection and test of deliverables. The cost of non-conformance also includes Keywords costs of rework and scrap. Project risk management is one of the important aspects of the pro- Crashing jects.

Integer programming 1. Introduction Nowadays project management is used as a significant skill in many industries. For this reason the knowledge of projects and their management are of high importance. The term project designates a temporary effort with a starting point and a unique product or a service as an ending point. Projects are mainly characterized by .
