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...

The Workforce Scheduling Problem (WSP) concerns the scheduling of a multi-skilled workforce to geographically dispersed tasks. An effective solution to the problem is critical to companies’ performance and success. Organizations are becoming increasingly aware of the importance of enhancing employee empowerment and involvement in decision making. However, traditional approaches implemented to t...

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...

This work presents a set of protocols for scheduling a meeting among agents that represent their respective user's interests. Four protocols are discussed: a) the full information protocol when all agents are comfortable with sharing their preference profile and free times; b) the approval protocol when only the preference profile can be shared; c) the voting protocol when only free time can be...

In this paper, we present an extension of the classical Resource Constrained Project Scheduling Problem (RCPSP). We present a new type of resource constraints in which staff members are involved. We present a new model where staff members can have several skills with different proficiency, i.e., a staff member is able to perform more than one kind of activity as well as the time need is complet...

A non-preemptive, zero time lag multi-project scheduling problem with multiple modes and limited renewable and nonrenewable resources is considered. A 2stage decomposition approach is adopted to formulate the problem as a hierarchy of 0-1 mathematical programming models. At stage one; each project is reduced to a macro-activity with macro-modes. The macro-activities are combined into a single m...
