critical path method (cpm) is one of the most popular techniques used by construction practitioners for construction project scheduling since the 1950s. despite its popularity, cpm has a major shortcoming, as it is schedule based on two impractical acceptance that the project deadline is not bounded and that resources are unlimited. the analytical competency and computing capability of cpm thus...

We examine whether cooperative planning and uncertainty affect the magnitude of rework in concurrent engineering projects with upstream and downstream operations, and explore the impact of such rework on project delays. Using survey data from a sample of 120 business process (BP) redesign and related information technology (IT) development projects in healthcare and telecommunications, our resu...

The time - cost tradeoff problem is one of the most critical issues in the project scheduling field and so far, a lot of research has been done with a variety of quantitative and qualitative approaches on this subject. In this research, we intend to provide a two - objective mathematical model which balances crash and delay for activities. So that it provides the right tools for decision makers...

Delay discounting in Lewis and Fischer 344 was compared using a novel concurrent-chains procedure. In the initial-link, two levers were available and a random-interval schedule was in effect. One terminal link provided a smaller reinforcer (1 pellet) and the other terminal provided a larger reinforcer (4 pellets). Terminal-link entry was scheduled randomly, with the constraint that entries to e...
