Inventory models in which the demand rate dependents on the stock- dependent are based on the common real- life observation that greater product availability tends to stimulate more sales. In this study we develop an inventory model to determine an optimal ordering policy for quantity dependent demand rate and time dependent holding cost items with delay in payments permitted by the supplier un...

This paper develops a model to examine the impacts of uncertainty about crop production and irreversibility of program participation on determining land rental payments and least-cost land retirement targeting in the Conservation Reserve Enhancement Program. Results show that under risk aversion only, the marginal cost of abatement and the average land rental payment are less than those under r...

Let G be a finite group and C(G) be the family of representative conjugacy classes of subgroups of G. The matrix whose H;K-entry is the number of fixed points of the set G=K under the action of H is called the table of marks of G where H;K run through all elements in C(G). In this paper, we compute the table of marks and the markaracter table of groups of order pqr where p, q, r are prime numbers.

We consider the design of multicast networks when both edges and nodes are sel sh agents. Our objective is a budget-balanced, strategy-proof mechanism which selects the set of clients to receive service and extracts payments from those clients. It constructs a network to provide the service, pays edges to participate in the network, and aims to maximize pro t from the transaction. We introduce ...
