Abstract (Croatian)

Rad analizira razne aspekte proizvodnje kabela kao što su proizvodni proces, poslovanje i tržišta te korištenje i implementacija simulacije u tvornici za proizvodnju kabela u svrhu optimiranja iskorištenja strojeva. Deatljno je opisana hrvatska tvornica ELKA d.o.o., uključujući proizvodni program, proizvodne procese i ustroj, prostorni raspored i tehnologiju (strojevi i softver CableBuilder and SAP). Simulacijski model načinjen je korištenjem softvera Siemens Tecnomatix 11 Plant Simulation. Ulazni podaci uključivali su broj narudžbi, godišnje proizvodne količine (u kilometrima i tonama), tehnološka vremena, udaljenosti između strojeva i druge. Izvođenjem simulacije uz variranje broja serija u ovisnosti o broju narudžbi, dobiveni su različiti rezultati. Rezultati su prikazani statističkim dijagramima koji sadrže podatke o proizvedenim količinama, vremenskim opterećenjima strojeva i ukupnim vremenima proizvodnje. Na temelju usporedbe rezultata, a za skraćenje ciklusa proizvodnje i povećanje iskorištenja strojeva, kao prikladna se iskazala tzv. strategija Form Postponement (odgoda otpočinjanja proizvodnih aktivnosti koje ovise o specifičnom zahtjevu kupca). Dio rada posvećen je izračunu potrebnog broja viličara za unutarnji transport.

Abstract

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.
