Abstract
El presente trabajo muestra una aplicación de un modelo de optimización en la asignación a turnos semanales de mano de obra operativa de manera unificada y centralizada entre dos centros de distribución. La principal decisión consiste en asignar la dotación existente de tres cargos operativos a los turnos de ambos centros de distribución, de forma de cumplir con la demanda de servicios requeridos por los clientes. Adicionalmente, se debe respetar que cada colaborador permanezca el turno completo en el CD asignado, que la cantidad total de personas por turno en un centro permanezca constante en la semana y que se respete la normativa de 2 horas extras máximo por persona. Todo esto minimizando el costo total de las horas extras incurridas. Este modelo fue resuelto y contrastado con las decisiones adoptadas las primeras 43 semanas del año 2016 en dos centros de distribución del operador logístico MULTILOG S.A. Para ello se utilizó como datos la dotación existente en dicho periodo y las horas hombre requeridas para prestar los servicios solicitados en ambos centros de distribución y turnos. Las horas hombre se obtuvieron producto de los flujos operativos de dicho periodo y la productividad de los mismos, obtenidos el primero desde el WMS1 del operador logístico y lo segundo de los presupuestos operacionales del mismo. Finalmente se compararon las horas extras incurridas en el periodo en cuestión y el obtenido producto del modelo de optimización. Se obtuvieron importantes resultados que serán la base para decidir gestionar de manera centralizada la mano de obra operativa de los distintos centros de distribución de este operador logístico.
The present work shows an application of an optimization model in the allocation to weekly shifts of operative labor in a unified and centralized way between two distribution centers. The main decision is how to assign the existing staffing of three operational positions, the shifts of both distribution centers, in order to meet the demand for services required by the Clients, respecting that each employee stays the entire shift on the assigned DC, The total number of people per shift in both centers is a constant amount each week and the norm of two extra hours maximum per person is respected. All this minimizing the total cost of overtime incurred. This model was solved in the period of the week01 to week43 of year 2016 in two distribution centers of the logistics operator MULTILOG S.A. For this purpose, the data used in this period and the man hours required to provide the services requested in both distribution centers and shifts were used as data. The man hours were obtained as a result of the operational flows of this period and the productivity thereof, obtained the first from the WMS of the logistic operator and the second of the operational budgets of the same. Finally, the overtime incurred in the period in question and those obtained by the optimization model were compared. Important results were obtained that will be the basis for deciding to centrally manage the operative labor of the different distribution centers of this logistics operator.
