We consider the optimal pricing problem in a service facility in order to maximize its long-run average profit per unit time. We model the facility as a queueing process that may havefinite or infinite capacity. Customers are admitted into the system if it is not full and if they are willing to...

In the first section, a firm with two servers must decide how to dynamically route arriving customers and allocate servers to two separate queues. The servers may work together or separately, and we provide insights into how the firm should optimally route customers and assign servers to queues....

In this thesis, we study the repair shop scheduling problem(repair-to-stock) and the production/inventory system pricing and production scheduling problem(make-to-stock). For both types of problems, we compare the performance of different scheduling policies. For the make-to-stock type problem,...

Der Call Center-Markt hat Ende der 90er Jahre und Anfang des neuen Jahrtausends einen rasanten Aufschwung mit zum Teil sehr hohen Ums?tzen erfahren, was zur Folge hatte, dass immer mehr Auskunftsdienstleister auf dem Markt kamen. Als Konsequenz daraus resultiert nun eine versch?rfte...

Nitrate pollution from agriculture is an important environmental problem, caused bythe excessive use of inorganic fertilizers. The internalization of this externality, via a tax onmineral nitrogen, could lead to a second best solution, reducing nitrate emissions. Severalauthors suggest that a...

We analyze the current state and future requirements of an agricultural income stabilization mechanism in a transition country – namely, the crop insurance system in Kazakhstan. Three objectives will be pursued: First, factors influencing the development of the crop insurance market will be...

A mathematical programming model is developed and associated to a spatial pattern index (Ripley L function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and...

The biological nature of agricultural production processes induce a higher degree ofuncertainty surrounding the economic performance of farm enterprises. This has contributedto the development and acceptance of forms of public intervention aimed at reducing incomevariability that have no...

A water-crop simulation/mathematical programming model of irrigation water demand in northeastern Colorado is formulated to develop an original concept of derived demand for consumptive use of water. Conventional demand functions for water deliveries are also developed, and the effect of...

Recently, Branzei, Dimitrov, and Tijs (2003) introduced cooperative interval-valued games. Among other insights, the notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we will present a general mathematical programming algorithm...
