Razvoj metode za izboljšanje proizvodnih, montažnih in logističnih procesov v podjetju

Seljak, Cene (author), Berlec, Tomaž (mentor)

Zaradi dviga potreb na trgu po proizvodih, z zahtevo po bolj konkurenčnih cenah in krajših dobavnih rokih, podjetja pogosto posegajo po izboljšavah proizvodnih, montažnih in logističnih procesov. V magistrskem delu je bila razvita metoda za izboljšanje proizvodnih, montažnih in logističnih procesov, ki vsebuje korake za popis obstoječega stanja in korake ter smernice za izboljšanje montažne celice, skladišča sestavnih delov in materialnega toka med proizvodnimi koraki. Uporaba metode za izboljšanje proizvodno montažnih in logističnih procesov se je prikazala na primeru podjetja, ki proizvaja hidravlične sestavine in sisteme. Na podlagi analize izboljšav ocenjujemo, da metoda razvita v magistrskem delu podjetju izboljšuje proizvodne, montažne in logistične procese. Podjetje je po vpeljavi metode na izbranem procesu doseglo 29,3 % krajši pretočni čas. Povprečno uteženi čas obdelave enote izdelka v montažni celici se je skrajšal za 19,99 %, pripravljalni čas montažne celice pa se je v povprečju izboljšal za 66,21 %. V skladišču sestavnih delov je podjetje v povprečju doseglo 21,68 % krajši čas obdelave enote izdelka in za 43 % krajši pripravljalno zaključni čas.

• Title: Development of a method for improving production, assembly and logistics processes in a company

Abstract

With growing market demand for products at more competitive prices and faster delivery times, companies often seek to improve production, assembly and logistics processes. In this master’s thesis a method for improving production, assembly and logistics processes was developed which contains steps for analyzing the current state and steps and guidelines for improving the assembly cell, warehouse for small components and material flow between production steps. Usage of the method to improve production assembly and logistics processes was demonstrated on the example of a company that produces hydraulic components and systems. Based on the analysis of the improvements, we estimate that the method developed in the master's thesis improves the production, assembly and logistics processes of a company. After implementing the method on a selected process, the company achieved 29.3 % shorter lead time. The weighted average cycle time in the assembly cell was reduced by 19.99 % and the assembly cell change-over time was reduced by an average of 66.21%. In the warehouse for small components the company achieved an average of 21.68 % shorter cycle time and 43 % shorter change-over time.
