In the facility location problem usually reducing total transferring cost and time are common objectives. Designing of a network with hub facilities can improve network efficiency. In this study a new model is presented for P-hub covering location problem. In the p-hub covering problem it is attempted to locate hubs and allocate customers to established hubs while allocated nodes to hubs are in...

The series Hybrid-Electric Drive (HED) architecture brings a significant range of potential benefits to military ground platforms. Electric-drive wheeled vehicles can feature electric traction motors in a conventional driveline, but also offer potential for motor incorporation into the axle or the wheel hub. The implementation of in-wheel hub drives presents challenges both in their design and ...

This article presents an analysis of Reception, Staging and Onward Movement hub (RSOM-hub) concept to support Canadian Forces (CF) Northern operations and provides insights into the optimal RSOM-hub locations. RSOM-hubs are permanent or temporary staging bases for cross-loading between strategic and tactical lift during military deployment and sustainment operations. Performance measures were d...

Organizations are being confused by simplistic, technology-driven models of e-business that allegedly enhance competitive and co-operative capability. Re-examining the perceived wisdom of electronic markets finds shallow, overlapping networks competing for membership, isolated pockets of collaboration and irregular flows of revenue, resembling an ad-hoc arrangement of spokes rather than a hub s...

In this paper, electro-magnetic design and thermal analysis of wheel hub motors, incorporated into the hub of a wheel and driven it directly, of electric vehicles were performed by using analytical and CFD methods. Since thermal management impacts the continuous power capability of electric machines, thermal analysis coupled electro-magnetic analysis are needed to reduce size and improve its pe...

For building trust in information services the criteria reliability, rightness/correctness, security, transparency, reputation, believability, completeness, and competence are particularly important. A comparison with four frameworks, which are used to evaluate information quality of information services outlines that trust relevant criteria can be found at the content and data security level. ...

Galaxy-ii is the designated initial common architecture for the DARPA Communicator project in the U.S. Its key feature is the ability to control system integration via a run-time executable scripting language. This paper describes our experience in developing complex systems based on the galaxy-ii framework. Our current system consists of four domains and two languages (English and Mandarin). U...

The Canadian Forces (CF) is seeking to establish permanent and temporary operational support hubs at strategic locations around the globe to improve its logistics support effectiveness and responsiveness for deployed operations. This paper addresses two logistics problems associated with the hub-based support concept, namely, hub location optimization and aircraft routing problems. A discrete f...

in this paper we present the problem of designing a three level hub center network. in our network, the top level consists of a complete network where a direct link is between all central hubs.  the second and third levels consist of star networks that connect the hubs to central hubs and the demand nodes to hubs and thus to central hubs, respectively. we model this problem in an incomplete net...
