Abstract
V današnjem svetu podjetništva so načrtovanje in z njim povezane dejavnosti bistvene za doseganje konkurenčnih prednosti, izboljšav v poslovanju, optimizacijo proizvodnje in zniževanje stroškov. Podjetja vse bolj stremijo k optimizaciji proizvodnje z namenom krajših pretočnih časov izdelave izdelka, pri čemer je za doseganje zastavljenih rokov naročil, ključnega pomena uskladitev dejanskih in načrtovanih pretočnih časov. Cilj je odpraviti oz. zmanjšati dejavnosti, ki ne dodajajo dodane vrednosti izdelku; odpraviti čakanja med delovnimi mesti, odvečni notranji transport, nepravilno postavljene proizvodne sisteme in izboljšati pretočnost materiala. V sklopu magistrskega dela smo s pomočjo analize toka materiala in podatkov o potrditvah delovnih nalogov iz SAP-programa definirali glavne vzroke daljših pretočnih časov in zamujanja naročil. Na podlagi dobljenih podatkov analize smo tako podali rešitve in predloge za izboljšave ter tako povečali kapacitete in produktivnost proizvodnje. Za novo postavitev oddelkov in delovnih mest smo uporabili Schmigalla-ovo trikotno metodo, s katero smo odpravili in minimalizirali notranji transport. V SAP smo z izvedbo analize podatkov o potrditvah delovnih nalogov ugotovili, da je pri podrobnem načrtovanju MRP-datuma začetka naročila uporabljen neustrezen čas čakanja med tehnološkimi operacijami, kar vpliva na zastavljen datum konca naročila. Novo definirani časi čakanja v veliki meri odpravijo zamujanja zastavljenih rokov naročila.

Title:
Reengineering of the production process for the manufacture of equipment to order
Abstract:
In today's world of entrepreneurship, planning and related activities are essential for improving business, optimizing production, reducing costs and gaining competitive advantage. Companies are increasingly looking to optimize production and shorten product lead times in order to meet deadlines. It is critical to harmonize actual and planned lead times. The aim is to eliminate activities that do not add value to the product, reduce waiting times between orders, prevent unnecessary internal transportation and fix improperly installed production systems to improve material throughput. As part of the master's thesis, we defined the main causes of longer lead times and order delays using material flow analasys and order confirmation data from the SAP program. Based on obtained data, we provided suggestions and solutions for the improvement of production capacity and productivity. For the new arrangement of departments and orders we used the Schmigalla triangular method, which eliminates and minimizes internal transports. In SAP we carried out an analysis of the data linked to order confirmations and found, that during the detailed planning of the disposition of the orders start date, an unreasonable waiting time was used, which later affected the orders end date. Due to the newly defined waiting times, delays in the order dates are largely eliminated.
