Resumen
La optimización del diseño de cadenas de suministro se ha convertido en un área de interés para académicos y ejecutivos, y ha sido densamente tratada en la literatura científica. Sin embargo, escasas investigaciones integran simultáneamente decisiones asociadas al flujo material y al flujo financiero, y muchas veces la integración solo se basa en el análisis de sensibilidad de algunos parámetros financieros. En la presente investigación se desarrolló un modelo para optimizar el diseño de cadenas de suministro directas abordando razones financieras como aspecto financiero a integrar. La aplicabilidad del modelo de programación lineal entera mixta (MILP) propuesto, se sustenta en un caso de estudio donde se diseña una cadena de suministro de tres eslabones que permite maximizar los beneficios y tomar decisiones como cantidad y ubicación de instalaciones, penalizando la función objetivo por demanda insatisfecha de los clientes.
El modelo propuesto fue resuelto usando el software WinQSB versión 2.0, específicamente el módulo de programación lineal y entera el cual utiliza el método de solución Branch and bound. Los resultados de la investigación demuestran que es posible y recomendable la inclusión de aspectos financieros, como razones de liquidez, en la optimización de la cadena de suministro.
The supplying optimization of the chains design he has become an of concern area for academicians and executives, and he has been densely tried in the scientific literature. however, scarce investigations integrate simultaneously decisions associated to the material flow and to the financial flow, and many times the alone integration is based on the sensibility analysis of some financial parameters. In the present investigation the chains design supplying developed a model for optimizar itself direct discussing financial reasons as financial aspect to integrate. the entire applicability of the lineal- programming model mixed ( MILP ) once was proposed, he is sustained in a study case where designs a supplying three- links chain that it permits to maximize the gainings itself and taking decisions as quantity and position of facilities, penalizing the objective show for unsatisfied request of the clients. The model once was proposed was solved using the software WinQSB version 2.0, specifically the lineal- and- entire- programming module, which utilize the solution method Branch and bound. The investigation's aftermaths prove that it is possible and commendable the financial- aspects, reasons inclusion of liquidity, in the supplying chain's optimization.
