The recent global economic downturn has increased an already perceived need in organizations for cost savings. To cope with such need, companies can opt for different strategies. This paper focuses on optimizing processes and, more specifically, determining the optimal lot production. To determine the optimal lot of a specific production process, a new software was developed that not only incorporates various productive and logistical elements in its calculations but also affords users a practical way to manage the large number of input parameters required to determine the optimal batch. The developed software has not only been validated by several companies, both Spanish and Mexican, who achieved significant savings, but also used as a teaching tool in universities with highly satisfactory results from the point of view of student learning. A special contribution of this work is that the developed tool can be sent to the interested reader free of charge upon request.
La crisis económica mundial ha acrecentado en los últimos años una necesidad, de por sí ya manifiesta en las organizaciones: el ahorro en costos. Para hacer frente a esto, las empresas pueden optar por diversas estrategias.
Este trabajo se enfoca en una de estas estrategias: la optimización de procesos y más concretamente, en la determinación del lote óptimo de producción. Para determinar el lote óptimo de un proceso productivo y concreto, se desarrolló un nuevo software que además de incorporar en sus cálculos diversos elementos productivos y logísticos, permite a su vez, gestionar de forma práctica el importante número de parámetros de entrada que se requieren para determinar el lote óptimo. El software que se presenta en este estudio, no solo ha sido validado en diversas empresas tanto españolas como mexicanas alcanzándose importantes ahorros, sino que también, ha sido utilizado como una herramienta docente en diversas universidades, logrando resultados muy satisfactorios desde el punto de vista del alumno y su aprendizaje. Un particular aporte de este trabajo, es que la herramienta desarrollada puede ser enviada al lector interesado de forma gratuita y con previa solicitud.
