Flödeseffektivisering genom metoder för effektivitetsberäkning och processkartläggningar : En fallstudie på ett massproducerande företag

Nilsson, Erik, Rydergren, Jonas January 2017 (has links)
Today it is important for production companies to create an overview of how the company is conducted to maintain its competitiveness. Mapping processes and material flows visualize production areas that create a direct value for the customer, while remaining areas or activities that do not add a direct value  should be minimized or eliminated. In order to identify material flows and non- value creation activities, complex models are required that can be combined in different ways. The study is based on a case study of an international mass-producing company that is partly located in the middle of Sweden. The factory studies four production lines, each producing the same product type but of different sizes. The aim of this survey is to create a deeper insight in a production process cost and material flows by combining a process-calibration method with methods for calculating the efficiency of processes. The first model used is a mapping process and material flow model to shorten lead times. The 2nd model used is a model that graphically shows which value and non-value creation activities to use the result in an efficiency calculation. The result consists of efficiency calculation, which shows that production Line 1 was streamlined by 19.12%, Line 2 by 6.68%, Line 3 by 18.73% and Line 4 by 4.77%. The goal of efficiency calculations is to achieve an optimal method where the efficiency is 100%. / I dagsläget är det viktigt för produktionsföretag att skapa en överblick över hur verksamheten bedrivs för att upprätthålla sin konkurrensförmåga. Att kartlägga processer och materialflöden synliggör områden i produktionen som skapar ett direkt värde för kunden, medan de resterande områden eller aktiviteter som inte tillför ett direkt värde bör minimeras eller elimineras. För att kunna identifiera materialflöden och de icke-värdeskapande aktiviteter krävs komplicerade modeller som kan kombineras på olika sätt. Studien är baserad på en fallstudie på ett internationellt massproducerande företag som delvis är beläget i Mellansverige. I fabriken studeras fyra produktionslinjer som alla tillverkar samma produkttyp men av olika storlekar. Syftet med den här studien är att skapa en djupare insikt i en produktionsprocess kostnader och materialflöden genom att kombinera en processkartläggningsmetod med metoder för att beräkna effektivitet. Den första modellen används för att kartlägga processer och materialflöden med avseende på att förkorta ledtider. Nästa steg är att använda en modell som grafiskt visar vilka aktiviteter som är värde- och icke-värdeskapande för att sedan kunna använda resultatet i en effektivitetsberäkning. Det sista steget består av effektivitetsberäkning och resultatet blev då att produktionslinje 1 effektiviserades med 19,12%, linje med 2 6,68%, linje 3 med 18,73% och linje 4 med 4,77%. Syftet med effektivitetsberäkningarna är att nå ett optimalt läge där effektiviteten är 100%.

Optimalizace logistických procesů v konkrétních organizacích / Optimization of logistic processes in specific organizations

Miksová, Michaela January 2017 (has links)
The thesis is concerned with logistic processes optimization in automotive industry companies that assemble car components. In the theoretical part of the thesis, areas and a structure of industrial logistics are defined and frequently used terms are explained. Then, theoretical approaches and practical applications used in the practical part are described. In the practical part, two particular companies are presented. The aim of the thesis is to optimize a tool that is used in the first organization during the process of logistic preparation of manufacturing. Secondly, the aim of the thesis is to analyse the process of material picking and handling before the supply of assembly line that is performed in the second organization and to suggest a solution that would eliminate non-value added activities. In the end, benefits of the thesis for both the organizations and the author are summarized.

Optimalizace logistických procesů v konkrétní organizaci / Optimization of logistic processes in a specific organization

Kubát, Michael January 2015 (has links)
This thesis is focused on some ways of optimizing logistic processes. In the theoretical part are described important terms which are going to introduce the reader to the processes, their analysis followed by optimization. Then there is the space devoted to the metrics by which processes are possible to be evaluated and managed. The practical part offers case study. It contains introduction to the organization, mapping of their processes, analysis of warehouse processes, and their subsequent evaluation and proposed improvements. Suggested improvements were made in the spirit of Lean Management. As another proposal to improve warehouse processes an analysis of inventories have been made and evaluated, which resulted in proposal for new layout of the warehouse, which will encourage further optimization.
