Time-cost tradeoff in fuzzy critical path analysis based on (1α) × 100% confidence-interval estimates
2008 Edition, October 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Project crashing is a method for shortening the project schedule by reducing the time of one or more critical activities to less than its normal activity time. The objective of crashing is to reduce project duration while minimizing the cost of crashing, which is also...

One New Method to Solve Time-Cost Tradeoff Problem
2010 Edition, December 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Time-cost tradeoff problem is one core problem in project scheduling, and also is one difficult problem which project manager have to face. Methods of solving the problem mainly contain method of network flow and method of mending the minimal cost. There into, for...

Time-Cost Tradeoffs Method for Hydropower Project Construction
2008 Edition, October 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

On the basis of the enactment data and information in workout plan, there are some traditional time-cost tradeoff methods, which optimize time-cost in the practice projects. It is difficult for these methods to achieve anticipate purpose as a...

Time-Cost Tradeoff Dynamic Scheduling Algorithm for Workflows in Grids
2006 Edition, May 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Service resources allocation and scheduling is one of the challenging and complex problems in computation-economy-driven open grid service architecture. This paper proposes a time-cost tradeoff workflow scheduling algorithm in which cost is optimized for...

One Improvement Algorithm of Solving Time-Cost Tradeoff Problem
2010 Edition, December 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a new algorithm is designed to solve time-cost tradeoff problem. Conventional algorithm is to reduce length of longer paths in activity network first, and then reduce shorter ones step by step. The contrary idea is adopted in the...

Pareto archived PSO optimization for time-cost tradeoff analysis
2007 Edition, September 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The present study proposes a bi-objective particle swarm optimization algorithm to find the cost profile over the set of feasible project durations, i.e., the time-cost tradeoff analysis. The proposed algorithm aims to achieve two goals: (1) to obtain the...

Impact of budget uncertainty on project time-cost tradeoff
2005 Edition, Volume 52, May 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Any project has to be supported financially. The budget allocated to the project, however, is subject to uncertainty due to various financial, market, and political risks. The present paper incorporates budget uncertainty into project time-cost tradeoff. The proposed model...

MOGA-based time-cost tradeoffs: Responsiveness for project uncertainties
2007 Edition, September 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Existing methods for analyzing the responsiveness of time-cost tradeoff (TCT) profiles with regard to project uncertainties ignore the cost parameter of project activities. To comprise this problem a novel method is developed in this work - it examines the effects...

The impact of time-cost tradeoff on the Internal Rate of Return for hydropower construction
2010 Edition, April 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The previous approach solved the time-cost tradeoff problem without considering the impact of Internal Rate of Return (IRR) of the project. The present paper incorporates it into project time-cost tradeoff for hydropower construction. The research on...

Time-Cost Tradeoff Problem of Human Resources Based on Hybrid GA
2011 Edition, Volume 2, November 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

As the duration of a large project is long, its consumption is significant. In order to complete the project efficiently, the project duration and the resources should be scheduled. During the project execution, if more resources are allocated, the make-span of an activity may be compressed....
