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.

Recently, the production control problem in stochastic manufacturing systems has generated a great deal of interest. The goal is to obtain production rates to minimize total expected surplus and production cost. This paper reviews the research devoted to minimum average cost production planning problems in stochastic manufacturing systems. Manufacturing systems involve a single or parallel failure-prone machines producing a number of different products, random production capacity, and constant demands.

It is very important to improve shop production performance in manufacturing process. The main manufacturing management methods include Kanban and Drum Buffer Rope (DBR) systems. In this paper computer simulation is used to evaluate the performance of these manufacturing systems. A simulation model was developed to collect and analyze some key performance indexes including total system output, flow time and average WIP invention. The optimal buffer size was found out by studying the two manufacturing systems at different capacities. The systems were also compared with and without machine breakdowns. The simulation model provided a significant insight into the two systems and the benefits of both the systems were realized
