The hub location problem appears in a variety of applications including airline systems, cargo delivery systems, and telecommunication network design. When we analyze an application separately, we observe that each area has its own characteristics. Hub location problems deal with finding the location of hub facilities and with the allocation of demand nodes to these located hub facilities. This...

What is the best distribution strategy to ship materials from a source to multiple destinations on a regular basis? This is a common question confronting logistics planners in many industries. This paper examines this issue in the context of the ocean freight industry. In particular, we tackle the economics of freighting raw materials through a transshipment hub, and propose a method to synchro...

Gear plunge shaving is one of the most efficient ways to finish gears. It has been a challenge for a long time to design and manufacture a plunge shaving cutter to induce gear tooth modification. This paper proposes a method for designing plunge shaving cutters to manufacture gears with modifications analytically. By integrating B-spline interpolation, differential geometry, and design optimiza...

Somer M. Nacy, Member, IAENG, Mohammad Q. Abdullah, and Mohammed N.Mohammed Abstract The Wildhaber-Novikov gear is one of the circular arc gears, which has the large contact area between the convex and concave profiled mating teeth. In (June 28, 1999), a new geometry of W-N gear with parabolic profile in normal section has been developed. This paper studies the generation of rack-cutters for p...

As a result of the analysis work on rock destruction by cutters milling machines, it was found that existing developments do not allow us to proceed derivation calculation d dependencies for determining fracture resistance, or can be used only in preliminary calculations known design parameters machines. To eliminate these disadvantages, combined physical and mathematical model process interact...

Conventional document and discussion websites provide users with no help in assessing the quality or quantity of evidence behind any given idea. Besides, the very meaning of what evidence is may not be unequivocally defined within a community, and may require deep understanding, common ground and debate. An Evidence Hub is a tool to pool the community collective intelligence on what is evidence...

Hubs are special facilities that serve as switching, transshipment and sorting points in many-to-many distribution systems. The hub location problem is concerned with locating hub facilities and allocating demand nodes to hubs in order to route the traffic between origin–destination pairs. In this paper we classify and survey network hub location models. We also include some recent trends on hu...

This paper presents a new method for optimizing the hub height of a wind turbine. In general, wind turbine energy production increases with the hub height, but so does the cost. Therefore, we must optimize the hub height. Here, we calculated the annual energy production using a wind probability function. This is a function of the hub height and the roughness, which is a surface characteristic. ...
