Economic assessment of the Champagne wine qualitative stock mecanism

Jacques Laye, Maximilien Laye (2006)

RAIRO - Operations Research

In the wine AOC system, the regulation of quantities performed by the professional organizations is aimed to smooth the variations of the quality of the wine due to the variations in the climate that affect the quality of the grapes. Nevertheless, this regulation could be damaging to the consumers due to the price increase resulting from the reduction of the quantities sold on the market. We propose a stochastic control model and a simulation tool able to measure the effects of this mechanism...

Ergodic properties of multidimensional Brownian motion with rebirth.

Grigorescu, Ilie, Kang, Min (2007)

Estrategias óptimas de publicidad y precio.

María del Carmen Castrodeza Chamorro, Rafael Caballero Fernández, Trinidad Gómez Núñez (1991)

Trabajos de Investigación Operativa

El modelo de control óptimo no lineal, considerado en este artículo, posee una variable de estado x proporción de clientes y dos variables de control: precio p y gastos en publicidad u. Realizando un análisis de estabilidad en diferentes planos de fase se demuestra, bajo ciertas hipótesis, que es óptimo introducir un producto en el mercado con un precio reducido y realizando una fuerte inversión al comienzo de la campaña.

Explicit formulae of distributions and densities of characteristics of a dynamic advertising and pricing model

Kurt L. Helmes, Torsten Templin (2015)

Banach Center Publications

We analyze the optimal sales process of a stochastic advertising and pricing model with constant demand elasticities. We derive explicit formulae of the densities of the (optimal) sales times and (optimal) prices when a fixed finite number of units of a product are to be sold during a finite sales period or an infinite one. Furthermore, for any time t the exact distribution of the inventory, i.e. the number of unsold items, at t is determined and will be expressed in terms of elementary functions....

Extensions of convex functionals on convex cones

E. Ignaczak, A. Paszkiewicz (1998)

Applicationes Mathematicae

We prove that under some topological assumptions (e.g. if M has nonempty interior in X), a convex cone M in a linear topological space X is a linear subspace if and only if each convex functional on M has a convex extension on the whole space X.
