dc.description.abstractThis study presents a decision support tool (DST) developed in Visual Basic for Applications (VBA) for managing the logistics of a Yard in the Chemical Industry with the objective to minimize operational costs. It describes the current operational challenges in a typical Chemical Industry’s Yard and the development of the DST focusing on the optimization problems related to decisions previously identified. The DST takes in consideration tankers, chemical tanks, truck scheduling, among others. The solution from the proposed DST reduced the costs associated with the Internal Truck movements by 34% and Yard operator duties reduced in 60% with the use of a Linear Assignment Problem, decision making heuristics and the Analytical Hierarchy Process as part of the methodology. The proposed DST can also be used to estimate the number of Dam parking spaces required in the facility. The simplicity of the software (i.e. only requires Excel to collect and administer information) and the quality of the results prompted interest from our collaborator’s management to implement the proposed DST.en_US
dc.description.abstractEste estudio presenta una Herramienta para Toma de Decisiones (HTD) desarrollada en VBA para el manejo de la logística en la industria de químicos con el objetivo de minimizar costos operacionales. El estudio describe los retos operacionales de la actualidad en el patio de la industria y el desarrollo de la herramienta enfocado en problemas de optimización relacionados a la toma de decisiones. La solución obtenida de la HTD reduce los costos asociados a los movimientos del camión por un 34%, tareas del operario del patio en un 60%, y tiene la capacidad de reportar la localización exacta y el estatus de cada tanquero mediante el uso del Problema de Asignación Lineal, Proceso Analítico Jerárquico y heurísticos para el manejo y toma de decisiones. La HTD propuesta también puede ser utilizada para estimar en número de estacionamientos en el dique necesarios en una compañía. La simplicidad del uso de la herramienta y la calidad de los resultados inspiraron interés de nuestros colaboradores en la facilidad para implementar la HTD propuesta.en_US
