Analysis of production in the cable factory

This work analyzes various aspects of cable manufacturing taking into account the production process, overview of cable business and markets, and use and implementation of simulation in a cable factory in order to optimize machine utilization. The focus is on ELKA d.o.o., a Croatian cable manufacturer, which has been described in detail in every aspect, such as product mix, processes and department, layout and technology (machinery and software - CableBuilder and SAP). Simulation model has been built using the software package Siemens Tecnomatix 11 Plant Simulation. The input data involved number of orders, annual quantities expressed in kilometers and tons, production times, layout distances between machines and other. The simulation runs give results for different alternatives obtained by changing the number of production batches in one year in relation to the number of orders. The purpose is to evaluate the possibility of introduction of a Form Postponement strategy to accelerate the lead times of cable supply and to maximize the utilization of the existing machines. The results are shown in statistical diagrams that contain data about number of parts produced, machine load and total working times. A comparison of results of different alternatives is performed. On the basis of the comparison, in order to accelerate the lead times and to maximize the utilization of the machines, it appears that a Form Postponement strategy is convenient. A part of this work contains the calculation of the number of forklifts needed for internal transport.
