The main aim of this report is to identify customer needs of outdoor products (jackets, pants, shoes etc.) directly through customer interviews and their consciousness about environmental and social sustainability. And my report can be used as a base for „product design‟ of Outdoor clothing. Also from my report both the suppliers and customers can get a good idea of „Environmental and social aspect of clothing technology‟.

When implementing an Enterprise Resource Planning (ERP) system, the system has to be adapted to the organisation. But just as important, the business processes of the organisation have to be reengineered in order to take full advantage of the ERP system. Noblessa Sverige AB, which is a sales company to the German kitchen producer Nobilia, has been growing remarkably since the start 2001 and has begun discussing an ERP system purchase. The order process of today has reached the limit of its capacity and something has to be done in order to meet the increasing sales volume. The purpose of this master’s thesis is to analyse and reengineer the order process as a preparation for an ERP system implementation. The outcome of this thesis is a suggestion of a process model of the order process, which also can be used as a foundation for a requirements specification for the ERP system purchase. In order to take advantage of the benefits of the existing order process, the reengineering starts with mapping the current process. Noblessa Sverige AB is a company that is growing and changing from one day to another. Changes have arisen during the writing of this thesis which has made the work even more interesting and challenging. The most important change is the opening of a central warehouse in Norrköping, which has been taken in consideration when we designed the new process model. After mapping and achieving an understanding of the current order process, we found a few things that could be improved. Above all, there exist many manual tasks that can be automated with the ERP system. Furthermore, there are tasks that should be moved from one department or function to another because it is more suitable to perform them there. We also found that Noblessa Sverige AB should improve the integration and cooperation with its suppliers, especially Nobilia. Nobilia is the main owner and main supplier of Noblessa Sverige AB, the conditions for cooperation are therefore very good.

<p><p>Isaberg Rapid AB is a company that manufactures for instance staplers and glue guns. Headquarters and main factory is located in Hestra but there are also subsidiary companies in Denmark, Netherlands, France, Spain, China and England. There are also two filial factories in France and China.</p><p>Today has the company no logistic guidelines committed and that leads to problems since the salesmen promise different things to the customers. This contributes too many different logistic solutions for Isaberg Rapid AB. The company has also noted problems with returns of goods.</p><p>The purpose with this task is to standardize and compile logistic guidelines, usable to all Isaberg Rapid AB's small to midsize customers. The aim is to increase the flow of information and reach a more standardized way to work than previously within the company and between the company and their customers. The task also includes development of a functioning system of returns usable to all customers.</p><p>Choice of methods has changed from literature studies to focus on interviews and document collections at the company. A large part of the implementation is comprised of interviews. This because the task were directed to Isaberg Rapid AB and it were therefore difficult to find any appropriate theory. Some visits, both in Hestra and Saint Amé, have been made. In development of the logistic guidelines have two other logistic guidelines from the company's customers been studied.</p><p>In the result part is the compiling of the logistic guidelines presented. The logistic guidelines are based on the collected documents from the company but also include parts from interviews and the studied logistic guidelines. This document should work as a tool for customers and concerned people at Isaberg Rapid AB. It contains important information before, during and after ordering. There are two versions of this document, one for the customer and one to use internally with extra comments.</p><p>In the end of the report there are some discussions about the difficulties that have been discovered. Finally, the questions given in the problem description will be answered in the conclusions.</p></p>

<p>Detta examensarbete har genomförts på Schenker Logistics AB där målsättningen har varit att analysera den nuvarande returprocessen och därefter presentera eventuella förbättringsförslag.</p><p>Den information som ligger till grund för resultatet av detta arbete har införskaffats via observationer och intervjuer med de personer som arbetar i returprocessen.</p><p>Analysen som utfördes resulterade i att ett flertal brister kunde identifieras i returprocessen. Alla dessa brister bidrog till att komplikationer uppstod vid returhanteringen av gods på Schenker Logistics AB. Några exempel på brister som identifierades är att gods som var i godkänt fysiskt skick, returnerades till Schenker Logistics AB utan angiven orsak till returleveransen. Dessutom dokumenterades inte skadeorsaker hos någon part i försörjningskedjan, vilket bidrog till att Schenker Logistics AB var ovetande om skadans uppkomst samt vem/vad som bidrog till att skadan uppstod. Ytterligare brister som kunde identifieras i returprocessen är att fraktsedlar med ett specifikt nummer ofta försvann, fraktsedlar som är synnerligen viktiga för att Schenker Logistics AB ska kunna hantera returgodset. Vidare identifierades brister i form av omotiverat antal hanteringsställen av returgodset både internt på Schenker Logistics AB men även externt. Detta utgör en risk till att returgodset kommer i kontakt med vanligt gods, men även att det kan uppstå fysiska skador på både returgodset och det vanliga godset. Utöver dessa brister finns det några fler som omnämns och förklaras mer i rapporten.</p><p>De förbättringsförslag som presenteras i denna rapport innefattar förändringar som kan leda till att returprocessen på Schenker Logistics AB, men även i hela försörjningskedjan, blir mer kontrollerad och hållbar jämfört mot dagens situation. Förutom en halvering av antalet scenarier som uppstår på Schenker Logistics vid mottagandet av returgods, kan dessa förändringar även bidra till kostnadsbesparingar i form av hanteringskostnader och administrativa kostnader hos både Schenker Logistics AB och deras kund Shell.</p> / <p>This examination report has been carried out at Schenker Logistics AB where the objective has been to analyze the current return process and then to present possible improvements.</p><p>In order to analyze the return process there was a necessity to obtain information of the present situation. The information has been acquired through observations and interviews with persons that work in the return process. The information that was obtained made it possible to analyze the return process.</p><p>The analysis that was carried out resulted in identification of several shortcomings in the return process. Every of these shortcomings contributed to complications with handling of returns at Schenker Logistics AB. An example of a shortcoming that was identified is that undamaged goods were returned to Schenker Logistics AB without specified reason for the return delivery. Moreover, there was lack of documentation of damaged goods, which contributed that Schenker Logistics AB was unaware of what causes the damages. Additional shortcoming that could be identified in the return process is that waybills with a specific number often disappeared; waybills which are highly important to Schenker Logistics AB in order to handle the returned goods. Furthermore, several unjustified transportations of the return goods took place both internally at Schenker Logistics AB but also externally. This was a risk as the return goods could come in contact with ordinary goods; but also that it could contribute to physical damages on both the return goods and the ordinary goods. In addition to these shortcomings some more is mentioned and explained further in this report.</p><p>The proposed improvements presented in this report include changes which can highly improve the return process at Schenker Logistics AB, but also in the entire supply-chain. The return process would most likely, after an implementation of the improvements, become more controlled and sustainable compared to today's situation. These improvement proposals can reduce the number of scenarios by half, scenarios that arise at Schenker Logistics AB when receiving the return goods. These changes can also contribute to saving in costs, in form of handling costs and administrative costs, at both Schenker Logistics AB and their customer Shell.</p>

<p>This master thesis presents a theoretical analysis of the interface between the Research&Development units and manufacturing. Streamlining this interface becomes more and more crucial for the smooth and high volume production. A literature research and a theoretical analysis of the crucial elements of inter-departmental communication between design and manufacturing build the basis for an improved communication model. The model acts as a guideline for the implementation of change processes. It emphasises the importance of both structural and individual elements of interventions. Both elements are important and necessary for the success, but their moment of result separates them. Hybrid methods counterbalance these differences. A first questionnaire issues the actual level of communication at the involved companies; a second questionnaire ascertains the attitude of the employees towards the proposed interventions. The model as a framework can be applied in general to all organisations, since the interventions that are necessary to be implemented are resulting from the analysis of the specific environments.</p>

Intensive competition on the global market puts great pressure on manufacturing companies to develop and produce products that meet requirements from customers and investors. One key factor in meeting these requirements is the efficiency of the product development and the production preparation processes. Design automation is a powerful tool to increase efficiency in these two processes. The benefits of automating the manufacturability analysis process, a part of the production preparation process, are shortened lead-time, improved product performance, quality assurance, and, ultimately, decreased costs. Further, automation is beneficial as it increases the ability to adapt products to new product specifications with production preparations done in a few or in a single step. During the automation process, knowledge about the manufacturability analysis process is collected and stored in central systems, thus allowing full control over the design of production equipments. Topics addressed in this thesis include the flexibility of design automation systems, knowledge-bases containing alternative design rules, the automation of the finite element analysis process, manufacturability analysis over several productions steps, and the determination of production limits by looping the automated manufacturability analysis process. These topics are discussed in connection with the rotary draw bending of aluminum profiles. It is concluded that the concept of design automation can be applied to the manufacturability analysis process at different levels of automation depending on the characteristics of the implemented knowledge. The concept of object orientation should be adapted when implementing a knowledge-base and when developing the geometrical representations of the products. This makes a design automation system flexible enough to edit underlying knowledge and to extend the targeted design space. It is possible to automate the process of setting up, running, and interpreting finite element analyses to a great extent, enabling the design automation system to evaluate its own design proposals. It is also possible to enable such systems to consider sequences of manufacturing steps and loop them to develop decision support guiding engineers early in the design process, saving time and money while still assuring high product quality.

<p>Fiskeby Board tillverkar returfiberbaserad kartong som oftast används till livsmedelsprodukter. Fiskeby producerar mot kundorder. När en order är färdigproducerad så lagras den i väntan på att kunden ska avropa delar av ordern. Korta leveranstider är en av de viktigaste faktorerna för att lyckas i kartongbranschen.</p><p>På senare år har marknaden för livsmedelstillverkning flyttats från norden, söder ut, till och omkring Tyskland. Detta faktum har gjort att avståndet från Fiskebys produktionsanläggning till deras kunder har ökat vilket har lett till ökade leveranstider.</p><p>Uppgiften med examensarbetet var dels att som oberoende part, hitta ett nytt logistiskt upplägg som innebar kortare leveranstider och högre leveransservice och dels att göra en totalkostnadsanalys över företagets logistiska verksamhet för att underlätta för Fiskebys fortsatta arbete.</p><p>Det enda sättet att minska leveranstiden är att minska avståndet mellan produkterna och marknaden och därför togs beslutet att gå vidare med att hitta en strategisk lagerpunkt.</p><p>För att hitta en strategisk lagerpunkt gjordes flera olika tyngdpunktsberäkningar där varje analys tog hänsyn till en eller flera faktorer så som efterfrågan, vinstmarginal, geografisk belägenhet och kundrelation. Av alla Fiskebys kunder så analyserades bara de kunder som är belägna på kontinenten. Det sammanvägda resultatet av analyserna visade att lagret bör placeras i närheten av Frankfurt, Tyskland.</p><p>Utöver denna analys undersöktes möjligheten att lagra Fiskebys produkter i närheten av en hamn i Tyskland och en hamn i Polen. De två senare alternativen visade sig vara ekonomiskt oförsvarbara och därför utgick allt vidare arbete ifrån tyngdpunktsanalysens resultat.</p><p>För detta resultat undersöktes skillnader i kostnader, leveranstider och miljöpåverkan gentemot det nuvarande logistikupplägget.</p><p>Kostnader ökade med ca 40 % där högre transportkostnader var den främsta bidragande orsaken. Leveranstiden minskade med ca 44 % mot nuvarande system, detta beror på att avstånden till kunden minskar betydligt. Minskade leveranstider leder också till ökad leveransservice vilket förbättrar Fiskebys situation på marknaden.</p><p>Eftersom miljön påverkas olika mycket beroende på vilket transportslag som används så beräknades diverse utsläppshalter för alla transportlösningar. Det visade sig att det blir en miljöförsämring då enbart lastbilar används som transportslag, övriga lösningar visade en klar miljöförbättring.</p> / <p>Fiskeby Board AB is manufacturing packaging boards based on first class recycled fibre to be used in the food industry.</p><p>Fiskeby begins their production when they receive a customer order. When a complete order has been produced it gets transferred to a nearby warehouse. Customers then send a delivery request for a partial part of the order to be transferred. One of the most important factors to be successful in the packaging board industry is to be able to deliver the product within the shortest amount of time.</p><p>The food industry has in the past years slowly been centralized in and around Germany. Fiskeby has therefore ambitions to gain new customers in that region since they are at the same time losing customers in Scandinavia. The lead times have increased due to the fact that the distance between Fiskeby and its customers has grown.</p><p>The goal of this project is to reduce the lead times by changing the existing logistical approach. Another goal is to make a total cost analysis to simplify future logistical evaluations, which will be made by consultants.</p><p>Our work showed that the only way of reducing the lead times is to get closer to the current market. We decided to evaluate the possibility of renting a warehouse by a third party logistic company.</p><p>To find a strategic place of storage, several centre of gravity analysis were made. Every analysis used different factors as input such as customer demand, margin of profit, geographical suitability, and ability to cooperate. The result showed that the warehouse should be located around Frankfurt, Germany.</p><p>Besides this result, two other studies were made. The first study evaluated the alternative of placing the warehouse close to a Polish harbour. The second study evaluated the alternative of placing the warehouse close to a German harbour. Both of these alternatives where proved to be too costly and a decision were made to continue the project by only looking at the result from the centre of gravity approach.</p><p>A comparison between the current logistic approach and the centre of gravity approach were made. Cost, lead time, and the environmental effects were compared and results showed that the cost associated with transportation and storage will rise by approximately 40 %.</p><p>The lead time however will decrease by approximately 44 % compared with the current system, due to shorter distances to customers. This will improve delivery service and also improve the current market situation.</p><p>A change of systems will increase emissions only if Fiskeby decides to use truck as the mode of transportation. In all other cases emissions will decrease.</p>

<p>Glue board is the base for much solid wood furniture produced by the IKEA-owned companySwedwood. Glue board is glued together from lamellas which can be produced in different waysbut in all cases is produced from boards coming from a saw-mill. In a saw-mill there aredifferent techniques for producing boards from logs. This thesis is about the Adaptive sawingconcept and its implementation at the Swedwood site in Kostomuksha. The idea with the conceptis to raise the output from the raw material, the yield. This is partly achieved by edging away islittle as possible from the boards in the saw-mill. The boards in the saw-mill are sawn in a waynot unlike through-sawing. When brought to the glue-board factory they are scanned in order tooptimise how to rip out as much lamellas as possible. The ripped lamellas are then cross-cut intodifferent sizes which later are glued to glue board. The objective of this thesis is to examine theyield from log to glue board for the log classes 135-148 mm and 110-120 mm, to try to improveit and to identify problem factors.In order to achieve that it was necessary to be sure of the volume figures at all stages. Theincoming volume was given by the scanner at the log sorting; effort was therefore put down tomake sure the figures could be trusted. For the smaller log class the logs were instead measuredby hand and the volume was calculated. The logs were then sawn in the saw-mill. This was donewith a low production speed and some problems were noted compared with when sawing with astandard technique. The absence of edging was the main reason for these problems. The saw-millline was deemed inappropriate for sawing the smallest log class but could handle the 135 -148mm class and the yield for that class was in line with what could be expected.In the lamella production line some minor problems were noted and the boards from the fourdifferent batches from the 135 – 148 mm log class got different yields mainly due to differencesin wood quality. The yield from log to glue board for these four batches varied from 17.6 % to21.5 % with an average at 19.3 %. The yield was lower than what was achieved for earlieradaptive sawing test batches on other places. Those tests were however done on other diameterclasses and with material that was slightly different than the one in Kostomuksha. Simulationswere done to check how much the yield could be raised if other lamella widths than just thestandard 46 mm lamella width was used. A raise to an average of 20.9 % could then be expectedwhen using the lamella widths 46, 55 and 60 mm.A similar simulation was done for the adaptive material that was produced from the 110 – 120mm log class. The total yield for that material rose from 19.4 % to 22.4 % when using morelamella widths. Lamellas from this material were tested as there was fear, that they would notmeet the standards for glue board production. This did however not prove to be the case. To usethe lamella production for producing such material is however not ideal, since a very smallvolume is produced.</p> / <p>Limfog är basen för de massivträmöbler som görs av IKEA:s helägda leverantör Swedwood.Limfog består av lameller som kan produceras på olika sätt.

Det här examensarbetet behandlar konceptet adaptiv sågning och dessimplementering på Swedwoods anläggning i Kostomuksha. Den grundläggande idén medkonceptet är att höja utbytet på råvaran. Detta uppnås bland annat genom att så lite som möjligtkantas bort på brädorna i sågverket. Brädorna sågas upp med vad man kan kalla genomsågning.När brädorna sedan förts till limfogsfabriken scannas de så att så mycket som möjligt ska kunnafås ut av varje bräda i form av lameller. Lamellerna som sågats ut kapas sedan upp i olikastorleksklasser beroende på kvalitet. Dessa limmas sedan ihop till limfog. Syftet med det härexamensarbetet är att ta fram utbytet från stock till färdig limfog för stockklasserna 135 – 148mm och 110 – 120 mm. Dessutom ska problemfaktorer identifieras och utbytet om möjligt höjas.För att uppnå detta syfte var det nödvändigt att ha säkra siffror för alla inblandade volymer isamtliga skeden. Stockarnas volym gav av en mätram vid timmersorteringen. Mycket kraft lasdärför ner för att säkerställa att dessa siffror var trovärdiga. Stockarna i den mindrediameterklassen mättes istället för hand och volym beräknades utifrån mätningarna. Stockarnasågades sedan på sågverket. Produktionshastigheten under sågningarna var låg och en delproblem i jämförelse med när sågning sker på mer traditionellt vis kunde noteras. Avsaknaden avkantning var huvudorsaken till dessa problem. Sågverkslinan visade sig vara olämplig för attsåga den mindre stockklassen, men kunde hantera stockar med en diameter på 135 – 148 mm.Utbytet för dessa var i linje med vad som kunde förväntas.I lamellproduktionslinjen kunde en del smärre produktionsproblem noteras och brädorna från defyra olika omgångarna av 135 – 148 mm stockar fick olika utbyte mest beroende på skillnader iråvarukvalitet. Utbytet från stock till limfog varierade från 17,6 % till 21,5 % och låg i snitt på19,3 %. Detta utbyte var lägra än vad som uppnåtts för adaptiv sågning på andra platser vidtidigare tester.

Totalutbytet för denna klass steg från 19,4 % till 22,4 % när fler lamellbredder användes.Eftersom det fanns viss oro att lamellerna skulle hålla lägre kvalitet övervakades de ilimfogsproduktionen.
