We show that transportation cost inequalities can be used to derive bounds for isotropic constants of convex bodies. We state a conjecture about transportation costs (and discuss support for it) which would have strong consequences for the slicing problem.

the economic burden of human immunodeficiency virus/acquired immunodeficiency syndrome (hiv/aids) is far greater than its direct medical costs. this study estimated annual indirect costs of the hiv/aids epidemic in islamic republic of iran in 2006-2007 from societal perspective. a patient cost diary in sets of six booklets covering a total of 6 months (from october 2006 and fallowed until march...

ABSTRACT NETWORK 2001 has been developed to provide transportation planners with additional flexibility in analyzing road systems. While NETWORK 2000 was limited to minimizing costs, NETWORK 2001 can use weighted objective function components to minimize road system length. This paper presents NETWORK 2001 and the new algorithm implemented in the program with its applications. Total open road l...

in this study the location routing problem with fuzzy parameters is taken into account, this problem involves determining the location of the depots and routing of the vehicles in order to serve the customers. in this study a location routing problem with fuzzy travel times and due dates is considered and two objective models are proposed. the considered objectives are minimizing the total cost...

in this paper, a supplier-retailer transportation system is investigated as a two-echelon environment. there is a single location in each echelon; the unique supplier at the first echelon has to replenish the retailer's warehouse at the second echelon. by the way, the shortage situation should be avoided. for this situation, a model is provided based on the traditional eoq model. the inven...

Electronic ticketing in public transportation based on smart cards is gaining momentum worldwide. It is widely recognized that a smart card system can deliver benefits to both passengers and operators, but due to its complexity, implementation can come at a considerable cost. Therefore, it is likely that a commercial appraisal from the perspective of the public transportation operator alone wou...

The principal focus of this research is to quantify opportunity costs in sequential transportation auctions. This paper focuses on the study a transportation marketplace with time-sensitive truckload pickup-and-delivery requests. In this paper, two carriers compete for service requests; each arriving service request triggers an auction where carriers compete with each other to win the right of ...

The question of which costs admit unique optimizers in the Monge-Kantorovich problem of optimal transportation between arbitrary probability densities is investigated. For smooth costs and densities on compact manifolds, the only known examples for which the optimal solution is always unique require at least one of the two underlying spaces to be homeomorphic to a sphere. We introduce a (multiv...
