In this paper, we show that for an almost locally separable metrizable space X, if its Wijsman hyperspace induced by one compatible metric is Baire, then X itself must be Baire. We also provide an example to demonstrate the necessity of separability.

This paper aims to build integrated forward and reverse logistics model, and to optimize it with closed loop supply chain (CLSC). After that, we evaluate the effectiveness of the proposed model with the numerical examples, and simulate it with a bottles distilling/sale company in Korea. This paper designs the method of calculation for a solution using optimization algorithms with the priority-b...

We present a deterministic kinetic data structure for the facility location problem that maintains a subset of the moving points as facilities such that, at any point of time, the accumulated cost for the whole point set is at most a constant factor larger than the current optimal cost. At any point of time, the cost that arise for a point depends on the status and the position of the point. In...

Inventory control is an important field in supply chain management, and a great deal of research efforts have been devoted to it over past few decades. In previous researches, there are some assumptions like that the lead time is an incontrollable variable, and all the items replenished are of perfect quality, and so on. However, those assumptions may not be fit for the real environments, and t...

Online mobile payment systems based on mobile cash provide privacy to customers and are feasible for real point of sale, virtual point of sale, and person-to-person mobile commerce scenarios. The merchant does not perform complex operations and the bank verifies the validity of the mobile cash before the merchant delivers the product. The bank must store the mobile cash spent in a database to p...

The introduction of electronic means of sale and dissemination of information goods has made a new set of pricing and bundling strategies possible. In particular, information goods have a negligible marginal cost. This provides producers with an incentive to sell goods in bundles. This new space of strategies also presents producers with a set of problems to solve. In most cases, a producer wil...

The problem of determining the optimal warranty period, assumed to coincide with the manufacturer’s lower specification limit for the lifetime of the product, is addressed. It is assumed that the quantity sold depends via a Cobb–Douglas-type demand function on the sale price and on the warranty period, and that both the cost incurred for a non-conforming item and the sale price increase with th...

conclusions chronic hepatitis c-related liver diseases impose a substantial economic burden on patients, families and the society. the current study provides useful information on cost of treatment and work loss for different disease states, which can be further used in cost-effectiveness evaluations. results the total annual cost per patient for chronic hepatitis c, cirrhosis and hepatocellula...
