This paper addresses a project scheduling environment in which the activities are partitioned among set of agents. The owner is interested completing as soon possible. Therefore, she/he defines rewards and penalties to stimulate agents complete faster. offers per-day reward for early completion intermediate milestones be met within specific due dates, with associated penalties. Each agent can, ...

Growing concern in the management of energy due to the increasing energy costs, has forced managers to optimize the amount of energy required to provide products and services. This research integrates an energy-based resource investment project-scheduling problem (RIP) under a multi-skilled structure of the resources. The proposed energy based multi skilled resource investment problem (EB-MSRIP...

One of the primary jobs a software project manager is to assign available resources development tasks in such way that results high-quality product at low cost. Software Project Scheduling (SPS) allocates most appropriate human resource activities right time reduce failure risks and minimise makespan. In literature, SPS problem referred as Multiple Resource-Constrained Problem (MRCPSP). The MRC...

The science of construction scheduling has gained importance in the past few decades and has become the focal point of construction management practitioners. Scheduling involves listing of a project's milestones, activities, and deliverables with intended start and finish dates. These are estimated in terms of resource allocation, budget and duration. Resource limits (manpower, machinery, mater...

this study aims to deal with a more realistic combined problem of project scheduling and material ordering. the goal is to minimize the total material holding and ordering costs by determining the starting time of activities along with material ordering schedules subject to some constraints. the problem is first mathematically modelled. then a hybrid simulated annealing and genetic algorithm is...

There are no analytical solutions for the problem of dynamic scheduling of resources for multiple projects in realtime. Mathematical approaches, like integer programming or network based techniques, cannot describe complexity of real problems (multi-projects environments have many interrelated elements), and have difficulties to adapt the analysis to dynamics changes. However, this complex prob...

This paper presents a multi-mode resource-constrained project scheduling problem (MRCPSP) with maximizing the net present value (NPV) form the project contractor’s point of view. Positive and negative cash flows are considered in this model. Furthermore, to make the model close to the real situations, four different models for positive cash flows are considered. Two meta-heuristics, called simu...
