Optimal ordering time interval taking account of time value

In this paper, the optimal inventory policies for an infinite lime span taking account of time value is discussed. First, bounds for the optimal ordering time interval are derived. Second, with these bounds, a simple algorithm to compute die optimal ordering time interval is developed. Numerical examples are given to illustrate the algorithm.     

RATIONING BY SELLER'S PREFERENCE AND PACIAL PRICE DISCRIMINATION

This paper investigates the behavior of a seller who has a preference for a certain group of customers. The seller maintains stable prices over time and supplements price rationing with a nonprice rationing. In this situation the preferred buyers would have priority over nonpreferred buyers in purchasing the commodity, and if the latter purchase the commodity they may be paying higher prices. It is proposed here that the premium paid by the nonpreferred buyers is a necessary bribe to induce the seller to forego his search for the preferred buyers.     

COMPUTER-INTEGRATED MANUFACTURING: A TAXONOMY OF INTEGRATION AND RESEARCH ISSUES

The past decade has seen an upsurgence in the number of manufacturing companies that are attempting to transform into computer-integrated enterprises. However, much of the computer-based integration efforts in these manufacturing organizations have been limited in scope and localized within certain areas of the organization (particularly, technology-intensive areas such as the shop floor). Such compartmentalized and myopic approaches to the development of computer-integrated manufacturing (CIM) systems undermine the ability of these systems to reach their fullest potential. CIM is much larger in scope and can impact an organization along various dimensions and at various levels. The fact that no completely integrated manufacturing enterprise has been developed to date can be attributed, in part, to a lack of understanding of the scope and implications of CIM. The purpose of this paper is, therefore, twofold. First, the paper presents a meta-schema (called TRIAD) for multidimensional and multilevel integration of a manufacturing system. Second, on the basis of the proposed meta-schema, the paper develops a taxonomical framework for defining key integration issues in CIM system design and discusses critical research needs that exist in this area. It is hoped that this paper will serve as a road map for research efforts that will enable the emergence of comprehensive CIM systems.
