Abstract  Title: A messy story – a case study of Secorocs process flow of DTH-pipes  Presentation date: 2010-06-02  Course: Bachelor thesis in business Author: Kristoffer Forsman Advisor: Kjell Gustafsson Keywords: Management control, process control, lean production, process flow analysis Purpose: The purpose of this bachelor thesis is to develop an overview of the process flow for a specific product, and with the help of this mapping based on a lean production philosophy show possible improvement proposals and how these can lead to a more efficient process flow. Methodology: I have used a case study of Secorocs DTH-pipes and my primary data are gathered through interviews and observations. I have used theoretical framework to establish a process flow analysis. This is to obtain data on process activities and whether they are creating value or not. This leads to a current mapping of the situation in Secoroc on DTH-pipes and then analyzed and suggestions for improvement are developed. Conclusions: That by using the above mentioned mapping of process flow of DTH-pipes, problem areas could be illustrated. Subsequently proposals for improvement could be produced from a lean production philosophy. Process flow analysis showed the non-value-adding process activities as primarily transport and delay. These activities could be rationalized and eliminated from developed proposals for improvement which resulted in a layout flowchart (bilaga3) as a proposal on how a better flow might look for Secoroc.

Följande examensarbete har genomförts på Cloetta i Ljungsbro. Syftet med följande examensarbete är att undersöka hur processen för allergenrengöringen kan effektiviseras.Allergenrengöringen som undersökts i detta arbete är den som utförs på produktionslinjen linjen Conbar. Examensarbetet har haft sin grund i att undersöka tillverkningsprocessen för att få en förståelse för allergenrengöringen och dess process. Därav kunde flödet för allergenrengöringen tas fram, även kritiska moment och eventuella förbättringsområden framtogs. Denna granskning har också legat till grund för en analys av verktygen/metoderna processflödesanalys, processflödesschema och SMED för att finna vilken av dessa som hade varit mest optimal vid effektiviseringsarbete av en allergenrengöring.Metoden är baserad på en explorativ undersökning där primärdata samlats in genom observationer och intervjuer. Samtlig data har sedan sammanställts i de olika mallarna för allergenrengöringens granskning. Sammanställningen ligger tillsammans med teori till grund för analys, resultat och de potentiella förbättringsområden som presenterats.Resultatet av undersökningen är att processflödesanalysen kan användas för att visualisera flödet och förbättringsområden. Aktiviteterna som genomförs i allergenrengöringar har visats till stor del enbart bestå av interna aktiviteter som inte går att ställa om till externa. SMED som har till syfte att omvandla interna aktiviteter till externa uppfyller då inte sitt syfte och användandet av processflödesanalys eller processflödesschema har istället rekommenderats. Resultatet har också bidragit till tre potentiella förbättringsområden som är; dubbel uppsättning av pumpar till chokladdoppen, införande av 5S på redskapshanteringen och att anpassa redskapen för det specifika arbetet som utförs. / The following bachelor thesis has been done at Cloetta in Ljungsbro. The purpose with the thesis was to investigate how the process for the allergen cleaning can be more effective.The allergen cleaning which have been investigated in this thesis is the line called Conbar.The bachelor thesis has been based on the review of the allergen cleaning and analysis template to describe the process flow, identify critical stages and to visualize potential improvement areas. The analysis template has also been the foundation to the analysis regarding which method (process flow analysis, process flow chart, SMED) is the most optimal to use when working to make the allergen cleanings more effective.The method is based on an explorative survey where primary data were collected through observations and interviews. All data has then been compiled into the different templates for the first step of analysis a process. The compilation constitutes together with the theory the foundation for the analysis, the result and the proposed potential improvement areas.The result of the survey is that the survey can be used to visualize the flow and improvement areas. The activities carried out in allergen cleanings have been shown to consist almost exclusively of internal activities that can not be switched to external activities. SMED, which aim is to transform internal activities to external, does not fulfill its purpose and the use of process flow analysis has been recommended instead. The result has also contributed to three potential improvement areas that are; doubling pumps for the chocolate caps, introducing 5S for tools handling and adapting the tools for the specific work performed.

LKAB Mekaniska i Kiruna, Sverige är en ståltillverkare som bland annat producerar avropsartikeln lingenomföring till moderbolaget LKAB. Målet med detta examensarbete är att minska på leveranstiden för sistnämnda artikel. För att åstadkomma detta undersöktes produktionsflödet i affärssystemet Monitor. Därtill genomfördes en litteraturstudie och intervjuer hölls med avdelningschefer och operatörer från LKAB Mekaniska. Utifrån detta identifierades tre faktorer som påverkar leveranstiden negativt. Dessa är kötiderna mellan operationerna, den bristfälliga planeringen som skedde vid skär- och maskinavdelningen, samt begränsningarna som höll upp produktionen i maskinavdelningen Vi hävdar att leveranstiden minskar om följande åtgärder genomförs: eliminera kötiderna mellan tillverkningsprocesserna, öka beläggningen och kapaciteten på tillverkningsmaskinen, implementera ett kanbansystem, ändra ordningsföljden i tillverkningsprocessen och slutligen införa ett säkerhetslager med färdigsvarvade stänger. / LKAB Mekaniska in Kiruna, Sweden is a steel-manufacturer that, among other things, produces lingenomföring for its parent company LKAB. The aim of this thesis is to decrease the delivery time of the aforementioned product. In order to achieve this, production flow in the business system Monitor ERP (Enterprise Resource Planning) was examined. In addition to this a literature study was conducted and interviews were held with department heads and machine operators from LKAB Mekaniska. Based on data collected, three factors were identified as negatively affecting the delivery time. These are queue times between operations, inadequate planning for the cutting and machinery department, as well as the limitations that kept the production back in the machinery department. We claim that the delivery time decreases if the following measures are realized: eliminate queue times between stages in the manufacturing process, increase personnel capacity related to the manufacturing machine, implement a kanban system, change the order of the manufacturing process and lastly to introduce a storage of ready-turned bars.
