Resource leveling is a variant of resource-constrained project scheduling in which a non-regular objective function, the resource availability cost, is to be minimized. We present an exact branch-price-and-cut approach together with a new heuristic to optimally or near-optimally solve the more general turnaround scheduling problem. In addition to precedence and resource constraints, also resour...

The changing competitive dynamics in the online environment has resulted in an increased pressure for organizations to gain IT resources and capabilities much ahead of their rivals. This has resulted in a surge in strategic IT alliances and online partnerships among organizations engaged in E-commerce. Combining resource based view of firm and contingency perspectives, we offer a framework to u...

—Power-consumption reduction, resource optimization and cost reduction are inevitable on geophysical instrument design. We propose a new method for serial data clock domain crossing (CDC) transmission to solve the resource utilization problem of data acquisition interface in geophysical instrument design, combining with the use of digital programmable logic chip FPGA/CPLD. This method changes ...

This paper presents a categorized-registry model for Grid Resource Publication and Discovery(GRPD) using software agents. We use Common Resource Model(CRM) specification to describe manageable resources as Open Grid Services Architecture(OGSA) services. We also adopt two-level registry mechanism to register corresponding resources of a Virtual Organization(VO) in order to obtain high GRPD effic...

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...

The transformation of traditional offline operations into digitally integrated offline-online environment has been a difficult challenge for firms from both operational and strategic perspectives, and has become a major topic of research for scholars. We conducted a comparative case study to explore an emerging trend – the convergence of offline and online operations and strategies. This study ...

Makespan and cost minimization are two important factors in project investment. This paper considers a multi-mode resource-constrained project scheduling problem with the objective of minimizing costs, subject to a deadline constraint. A number of studies have focused on minimizing makespan or resource availability cost with a specified deadline. This problem assumes a fixed cost for the availa...

The unique advantages of Bluetooth such as low power consumption capability, cheap hardware interfaces and easy set-up offer new application areas. This is a reason why Bluetooth is even considered for a Service Oriented Architectures (SOAs) consisting of a large number of resource-constraint devices. Although several proposals are available for reducing power consumption for intra-piconet comm...

The problem that we address in this chapter is an extension of the Resource-Constrained Project Scheduling Problem (RCPSP). It belongs to the class of project scheduling problems with multilevel (or multi-mode) activities, that permit an activity to be processed by resources operating at appropriate modes, where each mode belongs to a different resource level and incurs different cost and durat...

The multimode resource-constrained project scheduling problem (MRCPSP) is an extension of the single-mode resourceconstrained project scheduling problem (RCPSP). In this problem, each project contains a number of activities which precedence relationship exist between them besides their amount of resource requirements to renewable and non-renewable resources are limited to the resources availabi...
