The research aims to improve AMA Group’s project management address delays and identify the root causes. It uses PMBOK as a problem-solving approach, utilizing expert judgment historical data causes assess aspects. cause of is related scope, schedule, resource management. Work Breakdown Structure (WBS) Critical Path Method (CPM) are recommended tools for scope management, scheduling, These tech...

projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. an integer programming model is formulated for the project portfolio selection and scheduling.two heuristic algorithms, genetic algorithm (ga) and simulated annealing (sa), are presented to solve the problem. results of cal...

Large-scale projects often have several activities which are performed by subcontractors with limited multi-resources. Project scheduling with limited resources is one of the most famous problems in the research operations and optimization cases. The resource-constraint project scheduling problem (RCPSP) is a NP-hard problem in which the activities of a project must be scheduled to reduce the p...

It is a special resource allocation problem to adjust 2N paralleling activities into N activity pairs within resource limits in a CPM (Critical Path Method) network planning; also it is a hot topic in the field of project scheduling. So far, no simple and effective method has been designed to solve this problem. In this paper, an optimized algorithm is developed to adjust 6 paralleling activiti...

This paper solves a complex PS problem by employing a reproduction mechanism which is closer to natural than the common GA methods. The PS problem consists of: operations sequence constraints, alternative modes per operation, multi renewable resources, resource setups, and other properties. The resulting model is very complex; hence, common GA methods produce unfeasible solutions very frequentl...

My proposed work is inspired by the experiment that uses expert judgment for estimation of the cost on the basis of previous project results. In this paper estimator can use Analogical strategies as well as Algorithmic Strategies as they wish. The proposed method is divided into two phases. First phase computed the probability of each selected factors by ant colony system. Second phase combines...
