“…En concordancia con [7] y [8], para el SVRP se distinguen cuatro tipos de modelos: el VRPSD (VRP Stochastic Demand) es un VRP con demanda estocástica, m de vehículos cuya capacidad limitada atienden clientes con demanda desconocida que puede ser mayor a la capacidad del vehículo. Pueden presentarse dos escenarios: se incurre en costos por déficit al incumplir al cliente o, el vehículo debe retornar al punto de distribución para reaprovisionar la demanda restante [77], [78]. En el VRPSTT (VRP Stochastic Travel Time) cada cliente tiene que ser atendido en una ventana de tiempo [79], el modelo fue introducido por [80] y contempla ventanas de tiempo aleatorias para las rutas, planifica un conjunto de rutas antes de que se conozca el tiempo requerido para atender a cada cliente, de modo que se cumplan con estas restricciones [81].…”

“…Las comparaciones entre las soluciones obtenidas por el modelo estocástico y determinista han validado las ventajas y robustez de considerar los tiempos de viaje y de servicios estocásticos [77]. En ese sentido, [94] presentan un caso de estudio para una empresa de cuidados de la salud, modelan con programación estocástica un problema de VRPSTT con entrega de medicamentos e instrumentos y recogida de desecho y pruebas de laboratorio.…”

El presente artículo se realiza con el objetivo de establecer el estado del arte de los modelos de localización, inventario y ruteo con parámetros estocásticos. Se realizó una revisión sistemática de la literatura en las bases de datos ScienceDirect, ScholarGoogle, SpringerLink, Scopus, SemanticScholar, Scielo y ResearchGate. A través de preguntas orientadoras, se seleccionaron 99 artículos, de los cuales el 74% es literatura reciente entre 2015 y 2019. Se clasificaron los modelos individuales logísticos estocásticos, se propuso una taxonomía con un enfoque de investigación de operaciones, a partir de sus características, parámetros, restricciones, funciones objetivo y métodos de solución utilizados. Asimismo, se identificaron las tendencias y las futuras líneas de investigación. Como conclusión se identifican nuevas estrategias y políticas operativas que permiten mejorar el desempeño de la cadena de suministro, igualmente la ausencia de métodos de solución eficientes ha sido evidente en grandes instancias, según la vida real.

“…This requires the analysis of cargo capacity and the definition and the number of routes to be calculated. The planning of these activities can lead to additional problems and costs [31][32][33][34]. The definition and pricing of freight is an important activity for logistics systems.…”

The main purpose of this article is to present an overview of the applications of sustainable practices in logistic operations performed by Brazilian companies. To reach this objective, the following steps were carried out: (1) a review of the literature on logistics systems and sustainability in logistics activities; (2) the collection of sustainability reports published by companies that perform logistics operations, which are recognized in Brazil; (3) a content analysis of the reports collected and (4) a discussion of the results, cross-checked with the literature and the extrapolation of conclusions. It was possible to identify 22 sustainable practices, and these practices were grouped into five macro areas. The authors of this paper believe that the findings presented here can be useful for professionals and researchers in the implementation of sustainability practices in logistics systems.

“…This method identifies the main findings, trends, and future routes in multi-dimension of multimodal transportation [15]. Mandi et al presented a grouping formula based on the branch pricing to study the opportunityconstrained vehicle routing problem with stochastic demands and enhanced the solution quality by simulation experiments and sensitivity analysis [16]. Hu et al proposed an urban traffic model (AUTM) for predicting and avoiding the traffic congestion.…”

With the rapid development of online shopping in recent years, logistics distribution has received much attention from enterprises and online consumers. Logistics distribution involves many factors and complex processes; conventional qualitative methods are unable to provide an effective analysis. Thus, this paper sets a framework to solve the above problem. A case study of an E-commerce enterprise in Shanghai on logistics distribution is proposed to discretize the whole process and minimize the total costs. Then the AnyLogic software is used to simulate and optimize the system from three aspects, including routes selection, warehouses quantity, and warehouses layout. Finally, this paper analyzes the simulation results, which would provide some valuable references for practical logistics.
