This thesis has analyzed the design process within the Lean Manufacturing Equipment (LME) department of Virtual Manufacturing AB. This department offers customized solutions to improve the flow, processes, and ergonomics in internal logistics and material handling. The work incorporates scientific theories within Lean, such as Just-in-Time, Kaizen, and Jidoka. Additionally, theories on lean waste were also utilized.By examining an LME-project conducted in the summer of 2023, where several problems arose, a root cause analysis was performed. This was done by first identifying the responsibilities of the designers in the LME-process. Subsequently, an Ishikawa-diagram was created, focusing on the involvement of the designers. Finally, three areas of causation were selected and analyzed more thoroughly using the "5 Whys?" Method.The result of this method provided solutions in the form of three improvement suggestions, which are: • Automated tool for wheel selection.• Standardization of categorization of Karakuri products.• Improvement of documentation for revisions.These improvement suggestions were analyzed from a Lean perspective as well as their social, economic, and environmental sustainability. / Detta examensarbete har analyserat konstruktionsprocessen inom Virtual Manufacturing AB:savdelning Lean Manufacturing Equipment (LME). Denna avdelning erbjuder kundanpassade lösningar för att förbättra flödet, processer och ergonomin inom internlogistik och materialhantering. Detta arbete omfamnar vetenskaplig teori inom Lean så som Just-in-Time, Kaizen och Jidoka. Utöver detta nyttjades även teori om lean-slöserier.Genom att undersöka ett LME-projekt som genomfördes sommaren 2023 där flertalet problem uppstod gjordes en rotorsaksanalys. Detta gjordes genom att först konstatera konstruktörernas ansvar i LME-processen. Vidare skapades ett Ishikawa-diagram som sedan avgränsades till konstruktörernas involvering. Slutligen valdes tre orsaksområden som analyserades mer noggrant med hjälp av metoden “5 Varför?”.Resultatet av denna metod gav lösningar i form av tre förbättringsförslag, vilka är:• Automatiserat hjälpmedel för val av hjul.• Standardisering av kategorisering av Karakuri-produkter.• Förbättring av dokumenteringen av revisioner.Dessa förbättringsförslag analyserades från ett lean-perspektiv samt deras sociala, ekonomiska och miljömässiga hållbarhet.

Bakgrund: Intresset för processer och framförallt utveckling eller förbättring av processer har på senare år ökat. Detta kan ha sin grund i att många företag har behållit föråldrade rutiner och processteg samtidigt som verksamheten utvecklats, något som resulterat i onödigt komplexa processer som påverkat företags ekonomiska och praktiska prestationer. En annan orsak kan vara att företagsklimatet blivit allt tuffare. En process som under senare år fått ökat intresse inom företagvärlden samt kommer sätta stor prägel på denna uppsats är materialanskaffningsprocessen. Materialanskaffning beskrivs som en process innefattande samtliga de aktiviteter som krävs för att säkerställa att material tillförs en organisation. Syfte: Syftet med denna uppsats är inledningsvis att kartlägga samt identifiera brister i Holtabs materialanskaffningsprocess. Vidare är syftet att komma med eventuella förslag till hur Holtab kan reducera kvalitetsbristerna i materialanskaffningsprocessen för att på så sätt minska företagets kvalitetsbristkostnader. Metod: Denna uppsats är en fallstudie på Holtab AB. Studiens metod är i huvudsak kvalitativ med kvantitativa inslag. Uppsatsen har vidtagit en deduktiv forskningsansats med ett positivistiskt synsätt. Det empiriska materialet samlades in genom semi-strukturerade och ostrukturerade intervjuer samt en kvalitetscirkel. Vidare har uppsatsens teoretiska referensram baseras på litterära källor samt vetenskapliga artiklar. Slutsatser: Holtabs materialanskaffningsprocess har beskrivits genom en processkartläggning. Vidare har författarna identifierat materialanskaffningsprocessens kvalitetsbristkostnader samt dess orsaker. Avslutningsvis har författarna tillsammans med medarbetare på Holtab AB tagit fram förbättringsförslag till de brister som identifierats. / Background: In the recent years, the interest of processes and especially the development or improvement of processes has increased. This may be because many companies have kept obsolete routines and process steps while the businesses have developed. As a result the processes have become unnecessarily complex and affect the companies’ financial and operational performance. Another reason may be that the business environment has become tougher. A process that in the recent years has received an increased interest in the business world and will put its mark on this essay is the material procurement process. Material procurement is described as a process including all activities necessary to ensure that all the required material is supplied to an organization.  Purpose: The purpose of this essay is initially the map and identifies poor quality in Holtabs material procurement process. Further the purpose is to present suggestions on how Holtab can reduce their poor quality in order to reduce the company’s cost of poor quality. Method: The following essay is a case study on Holtab AB. The study is mainly performed in the form of a qualitative study which is supplemented by some quantitative elements. The study emanated from a deductive standpoint with a positivistic approach. The empirical data were collected by the usage of semi-structured and unstructured interviews as well as a quality circle. Further the theoretical framework was collected by literature and scientific articles.   Conclusions: Holtabs material procurement process have been defined and mapped through process mapping. Furthermore have the authors identified cost of quality deficiencies and the causes behind said deficiencies. Finally the authors have derived and presented suggestions for improving Holtabs material procurement process by reducing the quality deficiencies and therefore the related costs.

At ABB’s high voltage cable factory in Karlskrona, there is a line production that is regarded as a bottleneck. The production rate at this workplace as well as the large variations of setups has created two major problems. The first problem is that it has become difficult for the planning department to determine the lead times for delivery to the customers. The other problem is that the long setup times has made this line production the bottleneck of the whole production. The factory at ABB HVC includes a number of line productions, where each line has their own purpose and value adding processes. The armoring line AR50 that this project has the focus to improve has the last value adding processes for the factory’s main product. The factory’s main product is the Cross-Linked Polyethylene cable, shortened XLPE. There are several different advantages with the XLPE-cable system. First of all they are maintenance-free and environmentally friendly. The main reason that the XLPE-cable is environmentally friendly is because it have low electrical losses. Since the submarine cables are underground the cables are invisible and not effected by weather conditions. This project implements the method SMED as well as various methods from the LEAN transcript in order to reduce the setup times and create a more stable and effficient production. An Ishikawa diagram were used in order to determine the root causes of the problems. Later both technical and management solutions were proposed and implemented. The project has concluded impressive results regarding setup time reduction and annual cost savings. It also enlightens the large potential for further improvement. This project will be continued during the year of 2014 in order to implement the proposed solutions. The future improvements are not just technical but also related to management and group dynamics.

The Moelven Valåsen AB sawmill will within a 5-year period increase production from 375,000 𝑚3to approximately 500,000 𝑚3per year by building a new saw line. This has more led to the company going up from 2 shifts to 3 shifts to be able to meet this demand. This has led to the finished goods inventory before the customer has become full, and as a result the company has had to stand still. To investigate this, this thesis has investigated what the flow of the finished goods inventory looks like with the help of some tools to analyze the flow but at the same time develop the problems that may be the basis for this problem of the inventory becoming full. What has been concluded is that there are many different challenges to solving this problem. This thesis has provided an overview of where the problem may be in the flow and what it is due to. What has also been developed are some improvement proposals that could benefit the company and be developed so that the capacity of the warehouse can increase and become more efficient. / Sågverket Moelven Valåsen AB kommer inom en 5 års period att utöka produktionen från 375 000 𝑚3  till ca 500 000 𝑚3 per år genom att bygga en ny såglinje. Detta har mer fört att företaget har gått upp från 2 skift till 3 skift för att kunna möta denna efterfrågan. Det har lett till att färdigvarulagret innan kund har blivit fullt, och resultera i att företaget har behövt stått stilla. För att undersöka detta har detta examensarbete undersökt hur flödet på färdigvarulagret ser ut med hjälp av en del verktyg för att analysera flödet men samtidigt ta fram problematiken som kan tänkas ligga till grund till detta problem med att lagret blir fullt.  Det som har kommit fram till är att det finns många olika utmaningar för att lösa detta problem. Detta examensarbete har gett en överblick vart problematiken kan tänkas ligga i flödet och vad det beror på. Det som också har tagits fram är en del förbättringsförslag som skulle kunna gynna företaget och utvecklas till att kapaciteten på lagret kan öka och effektiviseras.

This diploma thesis deals with application of quality tools in production plant. Theoretical part deal with history of quality, current situation in quality management and describe some of quality tools. In practical part will be applied some of described quality tools. Some of them are already implemented in production but only partially and they are not used in full for more flexible and efficient production. Conclusions and results of this diploma thesis should prove that if we are using these tools in full, we can decrease extra cost in production.

Denna rapport utreder möjligheterna till att reducera ledtiden, med en uppskattning av minst 10%, för plockprocessen på den utlevererande avdelningen som kallas den ”avgående avdelningen” hos EJOT Sverige AB i Örebro. Företaget vill i dagsläget skapa sig en tydlig helhetsbild av processen samt få underlag, för eventuell framtida implementering, i form av förbättringsförslag för en ledtidsreducering. Under arbetets gång beskrivs nuläget utifrån datainsamling, intervjuer och observationer, i kombination med ett spagettidiagram som presenteras. De möjliga rotorsakerna till problemen kartläggs genom att skapa ett fiskbensdiagram som sedan analyseras. Analyserna visar på att processen är komplex och därmed även problemen. Orsaker som valts för vidare analys är: layout, körslinga och placering av låga gods.  Tre förbättringsförslag har tagits fram utifrån analyserna och dessa handlar om att skapa en ny optimerad layout, en ny optimerad körslinga samt att eliminera placeringen av låga gods.  Det fortsatta arbetet bör vara att optimera en ny lagerlayout samt se över och standardisera en ny körslinga. Företaget bör också se över möjligheterna att eliminera placeringen av gods på markplan. / This report investigates the possibilities of reducing the lead time, with an estimate of at least 10%, for the picking process at the delivery unit called the “outgoing department” at EJOT Sverige AB in Örebro. The company currently wants to create an overall picture of the process and get a basis, for possible future implementation, in the form of improvement proposals for a lead time reduction. During the work, the current situation is described based on data collection, interviews and observations, in combination with a spaghetti diagram that is presented. The possible root causes of the problems are mapped by creating an Ishikawa diagram which is then analyzed. The analyses show that the process is complex and thus also the problems. Reasons chosen for further analysis are: layout, driving loop and placement of low goods. Three improvement proposals have been developed based on the analyses and these are about creating a new optimized layout, a new optimized driving loop and eliminating the placement of low goods. The continued work should be to optimize a new warehouse layout and review and standardize a new driving loop. The company should also review the possibilities of eliminating the placement of goods on the ground floor.
