Operational Excellence

Currently, manufacturing is characterized by increasing complexity both on the technical and organizational levels. Thus, more complex and intelligent production control methods are developed in order to remain competitive and achieve operational excellence. Operations management described early on the influence among target metrics, such as queuing times, queue length, and production speed. However, accurate predictions of queue lengths have long been overlooked as a means to better understanding manufacturing systems. In order to provide queue length forecasts, this paper introduced a methodology to identify queue lengths in retrospect based on transitional data, as well as a comparison of easy-to-deploy machine learning-based queue forecasting models. Forecasting, based on static data sets, as well as time series models can be shown to be successfully applied in an exemplary semiconductor case study. The main findings concluded that accurate queue length prediction, even with minimal available data, is feasible by applying a variety of techniques, which can enable further research and predictions.

Este artigo estuda o problema de projeto de fábrica focalizada envolvendo a partição da instalação (planta) em subplantas e a alocação de capacidade em cada estação de trabalho das subplantas. O sistema de manufatura job-shop é representado por meio de uma rede de filas aberta genérica, e aproximações baseadas em métodos de decomposição são utilizadas para avaliar e otimizar o desempenho do sistema. O objetivo é reduzir a complexidade do sistema do ponto de vista da gestão do produto ou da gestão da estação, por exemplo, limitando-se a variância dos leadtimes dos produtos na rede. Apresenta-se um modelo de programação não-linear inteira para o problema e um algoritmo heurístico para resolvê-lo. Aplicando-se o algoritmo em alguns problemas testes, mostra-se que a partição da instalação em subplantas pode reduzir a variância dos leadtimes dos produtos na rede, sem necessidade de investimentos adicionais em capacidade. Além disso, algumas vezes é possível manter (ou até melhorar) o desempenho da rede, particionando-a em subplantas que necessitam de menos capacidade do que a configuração original da rede como uma planta única.
