A stochastic model for project selection and scheduling problem
Resource limitation in zero time may cause to some profitable projects not to be selected in project selection problem, thus simultaneous project portfolio selection and scheduling problem has received significant attention. In this study, budget, investment costs and earnings are considered to be stochastic. The objectives are maximizing net present values of selected projects and minimizing v...
متن کاملa model to solve project scheduling and staff assignment problems
the allocation of human resources to project activities in order to schedule them is one of the closest states to the actual conditions of scheduling problems. but regarding the fact that this problem belongs to the class of np-hard problems; so far the exact methods have only been able to solve the small size problems. in this study, the renewable resources are humans in a way that every staff...

متن کاملan inventory–scheduling model for supply chain of construction project
one of the important problems in project management is lack of available resources in proper time at project site that leads to lack of project implementation in due date. this problem may be lead to time delay in sending resources from suppliers and related origins in supply chain to project site. therfore, to better resources managmenet and also the improvement of supply chain condition, the ...
متن کاملdeveloping project scheduling model with makespan and robustness objectives
the research on project scheduling has widely expanded over the last few decades. the vast majority of these research efforts focus on exact and suboptimal procedures for constructing a workable schedule, assuming complete information and a static deterministic problem environment. project activities are scheduled subject to both technological precedence constraints and resource constraints, mo...
