Time-cost trade-off is one of the most important subjects in project management and of interest to contractors. The goal of time-cost trade-off is sensivity analysis of project costs to changes in activity duration in order to obtain the best combination of activity duration decrease, in a way that the sum of project costs is minimized. In the heuristics presented in this area, time crashing is...

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...

Security critical systems development needs to integrate both project and product risks assessment into the development. Such systems need to balance time to market constraints, cost demands, functional requirement, as well as security requirements. This advocate the use of techniques that support costeffective and risk-driven development. The aspect-oriented risk-driven development (AORDD) fra...

time, cost and quality are considered as the main components in managing each project. previous researches have mainly focused on the time-cost trade-off problems. recently quality is considered as the most important factor in project�s success, which is influenced by time acceleration that is the less time is spent the more success is gained. in time-cost-quality trade-off problems, each act...

This paper draws attention to project trade-offs significance in project management and critically reviews the current state of the knowledge on the elements to be considered and the methods to resolve trade-off decisions. Traditionally the elements to be considered in trade-offs are mainly limited to time and cost and to some extent quality or risk or the well-known Project Triangle. The trade...
