The scheduling problem under study may be viewed as an extension of the standard Multi-mode ResourceConstrained Project Scheduling Problem (MRCPSP) including Multi-Skilled Labor and will be called as MRCPSP-MS. This problem requires an integration of resource limitation, labor skills, and multiple possible execution modes for each task, and the objective is to minimize the overall project durat...

Many processes within production scheduling and project management involve the scheduling of a number of activities, each activity having a certain duration and requiring a certain amount of limited resources. The duration and resource requirements of activities are commonly the result of estimations, and thus generally subject to uncertainty. If this uncertainty is not taken into account the r...

We consider the problem of joint power control, signal-to-noise-and-interference-ratio (SINR) target setting, mode selection and resource allocation for cellular network assisted device-to-device (D2D) communications. This problem is important for fourth generation systems, such as the release under study of the Long Term Evolution Advanced (LTE-A) system standardized by the Third Generation Pa...

This paper studies the relationships between the choice of a sourcing mode for information systems, the value of the resources used in systems development activities and the presence of those resources at sufficient level within the firm. The objective is to better understand the factors underlying the decision to keep the development of an information system inside the firm or to entrust it to...

The radical technological improvements, the low cost and the popularity of Intel processors are leading the major multiprocessor system integrators to design and build the new parallel systems based on Intel microprocessors, which are interweaved historically with the Windows operating system. In this paper, we present the development of a kernel-mode device driver that performs efficient sched...

This paper addresses a general class of nonpreemptive resource-constrained project scheduling problems in which activity durations are discrete functions of committed renewable and nonrenewable resources. We provide a well known 0±1 problem formulation and stress the importance of themodel by giving applications within production and operationsmanagement. Furthermore, we prove that the feasibil...

In this work we propose a roadmap towards the analytical understanding of Device-to-Device (D2D) communications in LTE-A networks. Various D2D solutions have been proposed, which include inband and outband D2D transmission modes, each of which exhibits different pros and cons in terms of complexity, interference, and spectral efficiency achieved. We go beyond traditional mode optimization and m...

Many studies on the resource-constrained project-scheduling problem have been published, but literature further considering multi-mode or multi-project issues often occurring in the real world is rather scarce. In this research, two heuristic algorithms are developed to solve a multi-mode resource-constrained multi-project scheduling problem (MMRCMPSP). The first, a parallel scheduling algorith...

A recurring problem in project management involves the allocation of scarce resources to the individual jobs comprising the project. In many situations such as audit-staff scheduling, timetabling, and course scheduling, the resources correspond to individuals (skilled labour). This naturally leads to an assignment-type project scheduling problem, i.e. a project has to be performed by assigning ...
