In a merchandise depth test, a retail chain introduces new products at a small sample of selected stores for a short period prior to the primary selling season and uses the observed sales to forecast demand for the entire chain. We describe a method for resolving two key questions in merchandise...

This paper indicates how an information theoretic approach via the MDI (minimum discrimination information) statistic can be used to help provide a uniform approach to both statistical testing and estimation in various kinds of marketing analyses. Extensions to versions of the MDI statistic also...

This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws...

In this paper we propose an iterative method to solve an optimal control problem, with fuzzy target and constraints. The algorithm is developed in such a way as to satisfy the target function and the constraints. The algorithm can be applied only if a method exists to solve a crisp parametric...

Die starke Abhängigkeit von exogen determinierten Zuständen der Welt (Wetter, Krankheiten, Schädlinge etc.) ist konstituierendes Element der meisten landwirtschaftlichen Produktionsprozesse. Während diese Zustandsabhängigkeit auf der einen Seite eine Unsicherheitssituation entstehen lässt,...

This paper serves to document the REPA Forest Trade Model – a global model of forest trade that consists of ten products across two horizontal layers in a vertical chain. The model includes 20 regions: Five Canadian regions (Atlantic Canada, Central Canada, Alberta, BC Interior and BC Coast),...

In this paper, we analyze the potential impact on producers’ land-use decisions in moving from support payments based on entitlements to a single farm payment (SFP). Further, we then consider a single farm payment with a greening component as part of the 2013 CAP reform. Using data for...

В статье дан обзор существующих математических моделей оптимального управления финансовым портфелем коммерческого банка. Основной целью работы является...

Weakening demand for livestock and dairy produce, historically high prices for feed ingredients and increasingly strict regulations on animal waste management continue to put significant pressure on livestock and dairy operating margins. In this paper, we use representative farm mathematical...

The U.S. Energy Independence and Security Act of 2007 mandates the production of 16 billion gallons of cellulosic biofuels by 2022. Desirable feedstock properties, biomass to biofuel conversion rate, and investment required in plant and equipment differs depending on which of several competing...
