Construction project budgeting including time buffers and costs

Predicting project time and costs using earned value management based on trapezoidal fuzzy numbers

Projects include activities that must be carried out at certain dates, with specified costs and determined qualities in order to satisfy the stakeholders. Project control is one of the most important and widely used issues in project-based organizations and it has attracted a lot of attention. So far, in the field of project control, there have been a lot of research that were done in different...

On project scheduling with irregular starting time costs

Maniezzo and Mingozzi (Operations Research Letters 25 (1999), pp. 175–182) study a project scheduling problem with irregular starting time costs. Starting from the assumption that its computational complexity status is open, they develop a branch-and-bound procedure and they identify special cases that are solvable in polynomial time. In this note, we present a collection of previously establis...

Time/Performance Budgeting for Software Designs

Optimizing a reverse supply chain including transportation, operation, maintenance and remanufacturing costs

Reverse supply chain is a process dealing with the backward flows of used/damaged products or materials. Reverse supply chain includes activities such as collection, inspection, reprocess, disposal and redistribution. A well-organized reverse supply chain can provide important advantages such as economic and environmental ones. In this study, we propose a general framework and formulate a m...

Influence of Project Type and Procurement Method on Rework Costs in Building Construction Projects

While it is widely recognized that additional costs due to rework can have an adverse effect on project performance, limited empirical research has been done to investigate the influencing factors. The research presented in this paper aims to determine the influence of different project types and procurement methods on rework costs in construction projects. Using a questionnaire survey, rework ...
