Abstract

Abstract: The configuration of logistics networks for waste oil and fats collection services is a strategic point of great importance, since their disposal contributes to a number of environmental disturbances, problems in sewage pipes and wastewater treatment systems. Starting from this premise, this paper proposes location of ecopoints in the city of Montes Claros-MG, capable of optimizing the collection of the waste oil and fats in all urban area of the municipality. This proposal of location was constructed in two stages: in the first, the collection network was constructed by integrating a location model of facilities with a geographic information system (GIS). It was possible to model a collection network in the city of Montes Claros - MG containing 87,748 points referenced by geographic coordinates and representatives of residential points considered as potential generators of these residues. During the creation of the model, due to the high density of the network and the low quantity of facilities (p), which causes limitation in the solution, it was observed the need for thematization of the map and consequently the network partitioning in zones, which allowed to determine the initial amount of installations that were to be found in the solution. Finally, an application in the native language of Transcad, GISDK, was developed with a programming interface that was developed to automate the process of integration of the model in the GIS. The model allowed the creation of 12 networks with densities below 12000 points, allowing gain in the solution of the problem.

利用p-中值模型与地理信息系统集成实现生态点的定位

摘要:废油和油脂收集服务的物流网络的配置是一个非常重要的战略点，因为它们的处置会导致许多环境干扰，污水管道和废水处理系统的问题。从这个前提出发，本文提出了在Montes Claros-MG市的生态点的位置，能够优化该市所有城市区域的废油和脂肪的收集。该选址方案分两个阶段构建:第一阶段，将设施选址模型与地理信息系统(GIS)相结合，构建收集网络。可以在蒙特克拉罗斯- MG市建立一个收集网络模型，其中包含87,748个由地理坐标参考的点和被认为是这些残留物潜在产生点的居住点代表。在创建模型期间，由于网络密度高，设施数量少(p)，这导致了解决方案的局限性，因此观察到需要对地图进行主题化，从而将网络划分为区域，从而可以确定解决方案中要找到的初始安装数量。最后，利用Transcad本地语言GISDK开发了一个应用程序，并开发了一个编程接口，实现了模型在GIS中的集成过程的自动化。该模型允许创建12个密度低于12000点的网络，从而在解决问题时获得收益。

期刊介绍： Gestão & Produção is a journal published four times a year year (March, June, September and December) by the Departamento de Engenharia de Produção (DEP) of Universidade Federal de São Carlos (UFSCar). The first issue of Gestão & Produção was published in April, 1994. Actually, G&P was result of experience of professors of DEP/UFSCar in editing, in the beginning, "Cadernos DEP" in the 1980s, followed by "Cadernos de Engenharia de Produção". The last three issues of "Cadernos de Engenharia de Produção" were a test previous to the launch of Gestão & Produção because most of the journal characteristics were already established, like regularity.
