In this research, we study the multi-skill resource-constrained project scheduling problem, where there are generalized precedence relations between project activities. Workforces are able to perform one or several skills, and their efficiency improves by repeating their skills. For this problem, a mathematical formulation has been proposed that aims to optimize project completion time, reworki...

this study is related to an islamic project financing with a major focus on investigating the role of islamic finance in financing infrastructural development projects (toll roads, power plants, airports, and plants, as well as natural resource exploitation projects, such as hydroelectric dams, mining projects, oil and gas assets, and paper mills), especially in the context of pakistan. infrast...

Many project managers of a large scale project shortened delivery period of his or her projects unwillingly by the request of clients. However, some of them believe there is no difference between a large scale project and a small scale project in shortening the delivery period and accept shortening finally. This is because they are not informed theoretically of what impact can be made by shorte...

measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in irrigation and drainage project schemes. sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...

organizations need to evaluate project proposals and select the ones that are the most effective in reaching the strategic goals by considering sustainability issue. in order to enhance the effectiveness and the efficiency of project oriented organizations, in this paper a new multi-objective decision making (modm) approach of sustainable project portfolio selection is proposed which applies in...

In this study, we aim to present a new model for the resource-constrained project scheduling problem (RCPSP) considering a working calendar for project members and determined the skill factor of any member using the efficiency concept. For this purpose, the recyclable resources are staff resources where any person with multiple skills can meet the required skills of activities in a given time. ...

An ordinary steam turbine retrofit project is selected as a case study; through the retrofit, the project activities will generate emission reductions within the power grid for about 92,463 tCO(2)e per annum. The internal rate of return (IRR) of the project is only -0.41% without the revenue of carbon credits, for example, CERs, which is much lower than the benchmark value of 8%. Only when the ...

the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...
