A mathematical model for an optimal appointed delivery date on a home delivery market

Hidefumi Kawakatsu, Hiroaki Sandoh (2010)

RAIRO - Operations Research

In recent years, the home delivery market has rapidly been growing since customers can purchase a variety of products very easily via Internet. At the same time, however, customers tend to switch from a supplier to another seeking for better service for them. For this reason, it is necessary for suppliers to enclose their customers by means of various kinds of service and strategy. An appointed delivery date of a product ordered by a customer is one of important factors of supplier's services....

An analysis of supply chain decisions with asymmetrical retailers : effects of disruptions and static service cost on coordination mechanism

Kebing Chen, Lei Yang, Yanxia Liu (2012)

RAIRO - Operations Research - Recherche Opérationnelle

The risk of demand or production cost disruption is one of the challenging problems in the supply chain management. This paper explores a generalized supply chain game model incorporating the possible disruptions. We find that a nonlinear Grove wholesale price scheme can fully coordinate such a supply chain even when both market demand and production cost are disrupted. The nonlinear Grove wholesale price scheme has three sides to coordinate the decision behavior of the players. One is that the...

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.

Flexible measures in production process: A DEA-based approach

Alireza Amirteimoori, Ali Emrouznejad (2011)

RAIRO - Operations Research

Data envelopment analysis (DEA) has been proven as an excellent data-oriented efficiency analysis method for comparing decision making units (DMUs) with multiple inputs and multiple outputs. In conventional DEA, it is assumed that the status of each measure is clearly known as either input or output. However, in some situations, a performance measure can play input role for some DMUs and output role for others. Cook and Zhu [Eur. J. Oper. Res.180 (2007) 692–699] referred to these variables...

Un modelo para validar productos en un proceso de compra-venta.

Miguel Sánchez García, Carlos González Martín (1990)

Trabajos de Investigación Operativa

Uno de los problemas que se plantea en los procesos de compra-venta es el de determinar el conjunto de objetos que satisfacen las necesidades de los posibles compradores. Para resolver este problema es conveniente caracterizar los productos que, potencialmente, se desean adquirir a través de un número finito de atributos. Los objetivos válidos serán aquellos para los que los atributos asociados superen unos valores prefijados. Ahora bien, determinar los verdaderos valores de los atributos suele...
