Abstract: This paper explores a Mathematical model for obtaining the minimum total cost of Multi-items with Mult-objectives in a Fuzzy Environment. The paper incorporates four constraints such as warehouse space and the constraint, investment amount constraint, percentage of utilization of volume of the ware house space and the shortage level constraint by allowing shortages. The previous resea...

Reducing costs of manufactured products is one of the key issues of companies. Bar turning companies (mechanical subcontracting companies) are faced with the following dilemma: use a pull strategy or use a push strategy. Instinctively these companies produce more than demand required by customers. This strategy allows them to respond to requests forecasts and reduce their cost of changeover tim...

In this paper, we concentrate on discussing the inventory problem under bifuzzy environment and develop a class of multi-objective inventory model with bifuzzy coefficients. We give the bifuzzy transform operarion and prove the method of solving satisfied solution of multi-objective inventory model. These are applied to a practical inventory problem in which all inventory costs, purchasing and ...

ISPs selling IP data transmission with negotiated QoS need to prove to their customers the compliance of actual transmission quality with the negotiated QoS from their contracts. For this it is necessary to monitor the quality of end-to-end connections. Whereas passive monitoring of all traffic is prohibitively expensive, active test traffic can be sent regularly between routers and/or end-syst...

Unlike derivatives of financial contracts, commodity options exhibit distinct particularities owing to physical aspects of the underlying. An adaptation of no-arbitrage pricing to this kind of derivative turns out to be a stress test, challenging the martingale-based models with diverse technical and technological constraints, with storability and short selling restrictions, and sometimes with ...

We study the microeconomic effects in a reputation brokered Agent mediated Knowledge Marketplace, when we introduce dynamic pricing algorithms. We study the market with computer simulations of multiagent interactions. In this marketplace, the seller reputations are updated in a collaborative fashion based on the performance of the user in the delegated tasks. We investigate the different equili...

In Kenya, the marine sub-sector, though a significant source of livelihood and employment, remains small in terms of contribution to the national economy. This study, undertaken between October 2000 and March 2001, examines and provides an insight into the structure of marine fish marketing as well as identifies constraints in the marketing system in Malindi and Kilifi districts. Through the us...
