Diseño método de solución en cadena de suministro integrado a políticas de fijación de precios

El presente trabajo resuelve un modelo de optimización no lineal asociado a la gestión de cadena de suministro que integra decisiones de fijación de precios de venta de diferentes productos sustitutos, con decisiones de niveles de inventarios en todos los nodos de la red y decisiones de trasbordo de producto. Un aspecto clave en el modelo es la determinación de la demanda de los productos que tiene influencia en las distintas decisiones logísticas (inventarios y transporte) y mercadeo (fijación de precios) de la cadena. El objetivo es maximizar la ganancia de las empresas que pertenecen a la cadena de abastecimiento mediante un modelo multi periodo y multi producto.The next document presents a distribution and pricing model for a retailer that sells heterogenous products to maximize the profit. Given a supply chain that consists of N warehouses, M wholesalers and L retailers two heuristics are used for the deterministic approach to determine the inventory levels. We assume that price and travel cost are two mainly factors considered by the customers, and adopt the multinomial logit model to reflect the migration of clients between stores. Research puts in consideration the use of a genetic algorithm to establish an efficient price. The methodology is organized as follows. First, the best method in the deterministic approach is determined through the comparison between the inventory method POQ (Period order quantity) and the heuristic Silver-Meal both adapted to the proposed problem, taking in consideration how much to send, sale and receive. Second, the best method is integrated to the multinomial logit model to observe the migration of clients because of the sensitivity towards price and distances. Finally, the genetic algorithm is used to establish the price to sell in the retailer. Results shows that the profits obtained are far greater in the integrated approach than in the deterministic one. We evidence the importance of considering migration of clients and pricing policies to improve logistic decisions.Ingeniero (a) IndustrialPregrad
