GA Based Multi - Objective Time - Cost Optimization in a Project with Resources Consideration
نویسندگان
چکیده
Project planner’s main goal is to complete project with minimal time as well as minimal cost. Much effort (e.g. resources which demand cost) is required to complete the project in shorter time. There is a trade-off relationship between activity duration and its resources. This study employed a GA based multi-objective approach for time-cost tradeoff using resources-time tradeoff as input. Combining with modified adaptive weight approach (MAWA), this proposed optimization model can find out best optimal solution and Pareto front which provides flexibility to planners and decision makers in making efficient time-cost decisions. This proposed model was developed in MATLAB and applied to test problems. However, it is illustrated that this model could be useful to solve bigger networks in practice.

In this paper, we present a genetic algorithm (GA) for optimization of a multi-mode resource constrained time cost trade off (MRCTCT) problem. The proposed GA, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. Beyond earlier studies on time-cost trade-off problem, in MRCTCT problem, resource requirements of each execution mo...

Safety risk management has a considerable effect on disproportionate injury rate of construction industry, project cost and both labor and public morale. On the other hand time-cost optimization (TCO) may earn a big profit for project stakeholders. This paper has addressed these issues to present a multi-objective optimization model to simultaneously optimize total time, total cost and overall ...

Smooth implementation and controlling conflicting goals of a project with the usage of all related resources through organization is inherently a complex task to management. At the same time deterministic models are never efficient in practical project management (PM) decision problems because the related parameters are frequently fuzzy in nature. The project execution time is a major concern o...

Project success is assessed based on various criteria, every one of which enjoys a different level of importance for the beneficiaries and decision makers. Time and cost are the most important objectives and criteria for the project success. On the other hand, reducing the risk of finishing activities until the predetermined deadlines should be taken into account. Having formulated the problem ...

Today's competitive conditions have caused the projects to be carried out in the least possible time with limited resources. Therefore, managing and scheduling a project is a necessity for the project. The timing of a project is to specify a sequence of times for a series of related activities. According to their priority and their latency, so that between the time the project is completed and ...
