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...

Numerous studies have documented a high propensity for self-employment and business formation among return migrants relative to non-migrants. The literature points to the importance of remitted savings, migration duration, and number and types of jobs abroad for business formation upon return. Implicit in this scholarship is the assumption that migrants acquire not only financial capital, but a...

In this study, we aim to present a new model for the resource-constrained project scheduling problem (RCPSP) considering a working calendar for project members and determined the skill factor of any member using the efficiency concept. For this purpose, the recyclable resources are staff resources where any person with multiple skills can meet the required skills of activities in a given time. ...

In this research, we study the multi-skill resource-constrained project scheduling problem, where there are generalized precedence relations between project activities. Workforces are able to perform one or several skills, and their efficiency improves by repeating their skills. For this problem, a mathematical formulation has been proposed that aims to optimize project completion time, reworki...

This paper deals with 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. On the one hand, we focus on staff members, each of them having several skills, i.e, is able to perform more than one kind of activity. On the other hand, an activity has specific skill requirements that m...

The literature on practice effects and transfer from singleto dual-task performance and part-whole task learning are briefly reviewed. The results suggest that single-task training produces limited transfer to dual-task performance. Past theoretical frameworks for multi-task performance are reviewed. A connectionist/control architecture for skill acquisition is presented. The architecture invol...

Proper assignment of available human resources to software development tasks is a key issue in order to achieve successful results in a software development project. In this paper we present a fuzzy linguistic approach that utilizes fuzzy linguistic terms to support the selection of suitable human resources based on their skills and required skills from each project task. The approach follows a...

This paper addresses the multi-mode multi-skilled resource-constrained project scheduling problem. Activities of real world projects often require more than one skill to be accomplished. Besides, in many real-world situations, the resources are multi-skilled workforces. In presence of multi-skilled resources, it is required to determine the combination of workforces assigned to each activity. H...
