ABSTRACT

This work focuses on internal logistics (IL), which is defined as the flows of materials inside the same business or the same plant. We centre on the IL activities of a car-assembling company. The main objective is to propose simulation models’ concepts that evaluate assembling lines under the IL point of view. We present a real case study based on SEAT S.A., a company in the Volkswagen group. We developed a Discrete-Event Simulation model through the Plant Simulation software. The company set the main Key Performance Indicators, which are related to the logistics flows’ performance (LFP) and an assembly lines’ aisles utilisation. The results expose which aisles are overused, the disturbs among the logistics flows, and the LFP, regarding the total of backorders, the trips duration, and the routes’ length in terms of distances and time. Moreover, we offer aset of best practices for further applications in that field.

摘要

这项工作的重点是内部物流 (IL)，它被定义为同一企业或同一工厂内的物料流。我们以汽车组装公司的 IL 活动为中心。主要目标是提出模拟模型的概念，以在 IL 的角度评估装配线。我们以大众汽车集团旗下的 SEAT SA 公司为基础展示了一个真实案例研究。我们通过 Plant Simulation 软件开发了离散事件仿真模型。该公司设定了主要的关键绩效指标，这些指标与物流流程的绩效 (LFP) 和装配线的过道利用率有关。结果揭示了哪些过道被过度使用、物流之间的干扰以及 LFP、关于延期交货的总数、行程持续时间以及路线在距离和时间方面的长度。而且，
