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...

This paper, we presents a new primary-secondary-criteria scheduling model for resource-constrained project scheduling problem (RCPSP) with uncertain activity durations (UD) and cash flows (UC). The RCPSP-UD-UC approach producing a “robust” resource-feasible schedule immunized against uncertainties in the activity durations and which is on the sampling-based scenarios may be evaluated from a cos...

In this paper, we study the problem of how to react when an ongoing project is disrupted. The focus is on the resourceconstrained project scheduling problem with finish–start precedence constraints. We begin by proposing a classification scheme for the different types of disruptions and then define the constraints and objectives that comprise what we call the recovery problem. The goal is to ge...

In this paper, we present a variant of classical scheduling problems which deal with restricted resources. Unlike other models studied in the literature, the proposed model has no upper bound for the amount of available resources. The objective of this variant is to find a solution that maximises this amount at the end of the planning horizon. A hybrid evolutionary algorithm is proposed for thi...

This paper gives an overview of a new approach to Resource Constrained Project Scheduling. The approach is based on the combination of a novel optimization technique with limited discrepancy search, and generates the best known solutions to benchmark problems of realistic size and character.

Resource-constrained project scheduling with activity pre-emption assumes that activities are allowed to be interrupted and restarted later in the schedule at no extra cost. In the current paper, we extend this pre-emptive scheduling problem with setup times between activity interruptions and the possibility to fast track pre-emptive subparts of activities. The contribution of the paper is twof...

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

Multi-Mode Resource-Constrained Project Scheduling is an NP-hard optimization problem intensively studied due to its large area of applications. This paper concentrates on the evolutionary approaches to Multi-Mode Resource-Constrained Project Scheduling based on permutation encoded individuals. A new recombination operator is presented and a comparative analysis of several recombination operato...

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...
