In this paper, a preemptive multi-objective multi-mode project scheduling model for resource investment problem is proposed. The first objective function is to minimize the completion time of project (makespan);the second objective function is to minimize the cost of using renewable resources. Non-renewable resources are also considered as parameters in this model. The preemption of activities ...

Aimed at coordinated resource sharing in distributed, heterogeneous dynamic environment, OGSA supports distributed simulation effectively in resource management. GT3 Core provides a structure of service container, based on which a new mode of distributed simulation system has been designed. The new mode realized the separation of simulation resource and simulation applications, and supplied a s...

the aim of a multi-mode resource-constrained project scheduling problem (mrcpsp) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). these goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...

This paper analyzes the actuality and requirements of the integration of different-structure and distributed education resources. At present, the service mode of the education resource library system based on the network is changing from Client/Server mode to Browser/Server mode which generally uses ordinary WEB Browser as the user interface. However, from the use effect of recent years, the qu...

This research proposes a preemptive fuzzy goal programming model for multi-objective multi-mode resource constrained project scheduling problem. The objectives of the problem are minimization of the total time and the total cost of the project. Objective in a multi-mode resource-constrained project scheduling problem is often a minimization of makespan. However, both time and cost should be con...

background and objectives: surgical cancelation is a significant source of time and resource waste, patientsafety risk, and stress for patients and their families. in this study, a risk management-based approach is developed to prioritize factors contributing to surgical cancellation. methods: factors leading to surgical cancellation were comprehensively classified based on literature review.a...
