Abstract In most vehicle routing and crew scheduling applications solved by column generation, the subproblem corresponds to a shortest path problem with resource constraints (SPPRC) or one of its variants. This chapter proposes a classification and a generic formulation for the SPPRCs, briefly discus...
However, so far only the theoretical properties of shorter-path constraint filtering have been studied. We provide the first extensive experimental evaluation of the new algorithms in the context of the resource constrained shortest path problem. We show how reasoning about path-substructures in ...
Projects can fail, or not be completed if you cannot resolve resource constraints. Resource-constrained scheduling is often a balancing act. If you can’t hire enough people to manufacture a product and meet demand, then you might seek cheaper materials or reduce inventory. ...
The RRS-LRP integrates a number of classical optimization problems, such as the location problem and the vehicle routing problem with an embedded Resource Constrained Shortest Path (RCSP) sub-problem as its key building block. The generic RCSP has been well studied by Handler and Zang (1980), ...
For instance, in response to the need for more practical research, traditional resource-constrained project scheduling problems have been expanded to include non-preemptive multi-skill resources such as human resources, resulting in the Multi-Skill Resource Constrained Project Scheduling Problem (MCRCPSP...

However, while minimizing the task execution delay of resource-constrained mobile users, the potential power delay trade-off is a basic challenge to be solved. In addition, the high mobility of vehicles makes the task scheduling decisions more complicated in the presence of heterogeneous wireless ...
For data sharing in the TS of multi-layer deadline-constrained scientific procedures, few Virtual Machines (VM), which are heterogeneous in nature, are provided with remote storage services by each supplier. One of the TS techniques that optimizes cost and makespan objectives is the earliest ...
The classic Resource Constrained Shortest Path (RCSP) problem aims to find a cost optimal path between a pair of nodes in a network such that the resources used in the path are within a given limit. Having been studied for over a decade, RCSP has seen recent solutions that utilize heuristic...
