SIMULATION OF PRODUCTION PROCESS REORGANIZED WITH VALUE STREAM MAPPING

The philosophy of Lean production offers a wide variety of advantages. Lean production concept is understood as the realization of Lean principle through the efficient application of methods and tools, with faster and more effective discovering of wastes and mistakes in the production systems. This article contains a presentation of the simulation application on production process previously analyzed with Value stream mapping tool. The model was applied to a production line in the shipbuilding industry in Croatia. The production line current state is simulated with varying market requirements. Using Lean management tools, future improved state was developed and simulated. The simulation provides dynamic models with varying production performance results, unlike by applying only a Value stream mapping tool. During simulation runtime, adaptation of production process by varying resources assignment to continuous working cell was done to fulfill order requirements on time.Original Abstract: Filozofija Lean proizvodnje nudi siroku paletu prednosti. Lean koncept proizvodnja predstavlja ostvarenje Lean principa kroz ucinkovitu primjenu metoda i alata, za brze i ucinkovitije otkrivanje gubitaka i pogresaka u proizvodnim sustavima. Ovaj clanak sadrzi prikaz koristenja simulacije proizvodnog procesa koji je prethodno analiziran i reorganiziran pomocu Mapiranja toka vrijednosti. Model je primijenjen za jednu proizvodnu liniju u hrvatskoj brodogradevnoj industriji. Trenutno stanje proizvodne linije je simulirano s varijabilnim zahtjevima trzista. Koristenjem alata Lean proizvodnje, razvijeno je i simulirano buduce stanje toka vrijednosti. Simulacija omogucava dobivanje i analizu dinamickih modela s promjenjivim performansama proizvodnog sustava, za razliku od primjene samo alata Mapiranja toka vrijednosti. Tijekom simulacije, koristena je prilagodba proizvodnog procesa variranjem pridodavanja resursa radnoj stanici, koja je sluzila za ispunjavanje zahtjeva trzista na vrijeme.
