Item type:Publication, Secuenciación de trabajos en una línea de SMT con enfoque multiobjetivoA partir de 1850, los sistemas productivos han evolucionado de forma muy rápida, especialmente a partir del último tercio del siglo xx, debido a la globalización y a la competencia empresarial, regida por la capacidad de los países para producir de manera más eficiente que los demás. De esta manera, estos países tienen dominio, a nivel mundial, de los ámbitos industrial y tecnológico; las naciones más desarrolladas son, por consecuencia, los Estados más ricos, en su mayoría producto de sus estrategias de producción. Esta situación es efecto, precisamente, de dicha evolución que incluye la administración de los sistemas, los procesos y la tecnología. En este sentido, cuando inició la revolución industrial, el esfuerzo del empresario se enfocó en lograr producir lo máximo posible, aun a costa de la seguridad de su personal. Sin embargo, esta forma de proceder tuvo que mejorar al avanzar el tiempo y desarrollar una mejor experiencia en actividades productivas, logrando la evolución e identificar así diferentes medios para lograr la administración de operaciones, a finales del siglo xix y principios del XX. La administración de operaciones tiene como razón de ser, la utilización de técnicas y metodologías que logren la coordinación de las áreas funcionales de la empresa con el área de producción. En esta administración se agrupan técnicas de mejora continua, control de producción, cuidado de la planta y la maquinaria, la logística de la empresa, así como la optimización de procesos, sin importar que sea empresa de bienes o servicios.66 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Insular Biobjective Routing with Environmental Considerations for a Solid Waste Collection System in Southern Chile(2017) ;Daniela S. Arango González; Pablo A. Miranda<jats:p>This paper presents a biobjective problem for a solid waste collection system in a set of islands in southern Chile. The first objective minimizes transportation cost and the second one reduces the environmental impact caused by the accumulation of solid waste at the collection points. To solve this problem, biobjective mixed integer linear programming is used. In the model, an itinerary scheme is considered for the visit to the islands. The model decides which collection points are visited per island, the collection pattern, and quantity of solid waste to be collected at each site. The quantity of solid waste is obtained dividing the solid waste generated in the island by the number of collection points selected in that same island and the frequency of visits. For this problem, we considered that the environmental impact function varies through the days during which solid waste is accumulated at each collection point. We present an instance based on real data for a set of islands in Chiloe and Palena regions in southern Chile, in which the deposit node is Dalcahue. We used the epsilon-constraint method and the weighted sum method to obtain the Pareto front, using commercial optimization software.</jats:p>Scopus© Citations 11 17 1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Combined Use of Mathematical Optimization and Design of Experiments for the Maximization of Profit in a Four-Echelon Supply Chain(2018) ;Daniel Arturo Olivares Vera; ;Eleazar Puente Rivera ;Mónica López-CamposPablo A. Miranda<jats:p>This paper develops a location-allocation model to optimize a four-echelon supply chain network, addressing manufacturing and distribution centers location, supplier selection and flow allocation for raw materials from suppliers to manufacturers, and finished products for end customers, while searching for system profit maximization. A fractional-factorial design of experiments is performed to analyze the effects of capacity, quality, delivery time, and interest rate on profit and system performance. The model is formulated as a mixed-integer linear programming problem and solved by using well-known commercial software. The usage of factorial experiments combined with mathematical optimization is a novel approach to address supply chain network design problems. The application of the proposed model to a case study shows that this combination of techniques yields satisfying results in terms of both its behavior and the obtained managerial insights. An ANOVA analysis is executed to quantify the effects of each factor and their interactions. In the analyzed case study, the transportation cost is the most relevant cost component, and the most relevant opportunity for profit improvement is found in the factor of quality. The proposed combination of methods can be adapted to different problems and industries.</jats:p>Scopus© Citations 6 20 2 - Some of the metrics are blocked by yourconsent settings
