Project scheduling with limited resources is a challenging management problem that is of immense importance to both practitioners and researchers. This problem is known to be NP-hard even under the simplifying assumptions of single renewable resource constraint, its constant availability over time and minimization of makespan as objective. This paper presents an improved Genetic Algorithm (GA) ...

This paper presents a Multi-objective Hyper-heuristic Evolutionary Algorithm (MHypEA) for the solution of Scheduling and Inspection Planning in Software Development Projects. Scheduling and Inspection planning is a vital problem in software engineering whose main objective is to schedule the persons to various activities in the software development process such as coding, inspection, testing an...

This paper introduces a multi-factory scheduling problem with heterogeneous factories and parallel machines. problem, as major part of supply chain planning, includes the finding suitable factory for each job assigned jobs at factory, simultaneously. For first time, this studies multi-objective in production network which has its customers demands can be satisfied by itself or other factories. ...

In practice, organizations work in general on more than one project which share some or all the available resources. In this work hybrid heuristics that combine Random Sampling heuristics and Backward-Forward methods are developed for the Resource-Constrained Multi-Project Scheduling Problem (RCMPSP). This heuristic approach has been successfully applied to resource-constrained single project s...

Effective project management requires reliable knowledge of cash required in different stages of project life cycle. Getting this knowledge is highly dependent on sophisticated consideration of project environment. Nature of projects and their environments are associated with uncertain conditions. In this paper, a new project cash flow assessment method based on project scheduling is proposed t...

The project resource leveling problem was proposed to smooth resource usage and reduce resource fluctuation, while the resource-constrained project scheduling problem focuses on minimizing the project duration with limited resources. Solving the two interrelated problems separately is unlikely to result in a globally optimum schedule. The few integrated optimization methods that have been devel...

In this paper the multiple projects resourceconstrained project scheduling problem is considered. Several projects are to be scheduled simultaneously with sharing several kinds of limited resources in this problem. Each project contains non-preemptive and deterministic duration activities which compete limited resources under resources and precedence constraints. Moreover, there are the due dat...

In many real-world scheduling problems (eg. machine scheduling, educational timetabling, personnel scheduling, etc.) several criteria must be considered simultaneously when evaluating the quality of the solution or schedule. Among these criteria there are: length of the schedule, utilisation of resources, satisfaction of people’s preferences and compliance with regulations. Traditionally, these...
