Modern processors come close to executing as fast as true dependences allow. The particular dependences that constrain execution speed constitute the critical path of execution. To optimize the performance of the processor, we either have to reduce the critical path or execute it more efficiently. In both cases, it can be done more effectively if we know the actual instructions that constitute ...

A considerable problem in competitive trade world is choosing the best supply chain. As a result in much more serious circumstances of competitions looking for the best supplier for manufacturing, for preparing raw material, is very significant. Meantime suppliers have different scenarios to be fulfilled, such as changing selection variables like lead-time, transportation cost and transportatio...

The multi-constrained path (MCP) selection problem occurs when the quality of services (QoS) are supported for point-to-point connections in the distributed multimedia applications deployed on the Internet. This NP-complete problem is concerned how to determine a feasible path between two end-points, so that a set of QoS path constraints can be satisfied simultaneously. Based on the branch-and-...

of a thesis at the University of Miami. Thesis supervised by Associate Professor Dilip Sarkar. No. of pages in text. (37) A GPS system selects routes between two points with minimum physical distance or minimum driving time. Here we address a different type of route selection problem. Given a road map with driving distance and wireless connectivity for each road segment, find a driving route th...

Supplier selection is one of the most critical activities of purchasing management in supply chain and managers increasingly face sourcing decisions of how to selected suppliers. This paper illustrates the development of a sourcing decision that provides support for the buyer firm in supply chain.The models developed here, involved selecting between single and dual sourcing. Outside and local s...

This paper presents a new algorithm for dynamic routing of bandwidth guaranteed tunnels where tunnel routing requests arrive one-by-one and there is no a priori knowledge regarding future requests. This problem is motivated by service provider needs for fast deployment of bandwidth guaranteed services and the consequent need in backbone networks for fast provisioning of bandwidth guaranteed pat...

Path selection is one of the critical aspects in emergency evacuation. In a fire scene, how to choose an optimal evacuation path for firefighters is a challenging aspect. In this paper, firstly, a dynamic triangular network model formed by robots is presented. On the basis of this model, directed graph is established in order to calculate direct paths. Then multiparameter information fusion whi...
