Studien har utförts på ett företag för att öka förståelsen för hur kartläggning av tjänsteprocesser och förbättringsarbete inom det området går till. Det har identifierats sex olika problem i form av otydlig planering, mycket ställtider, överarbete, dålig struktur i projektarkiv och brist på förbättringsarbete som leder till att processen står still i utvecklingen. Med hjälp av fyra förbättringsförslag syftar studien till att öka produktiviteten i processen.

The production process has been carefully observed and the capacity has been calculated for each station. The production capacity included the capacity of each station within the production line but also information from previous time studies has been used during the research. The time studies have been performed by a consultant though because the production process has developed since these studies were performed, the information had to be updated. The updated information together with the calculated capacity of each station, have been used to create a spread sheet which can be used as a planning tool. Recommendations for future actions have been developed, with help from the analysis and conclusions. These recommendations will support ABB in their future work.

Studien har undersökt Botrygg ABs ställtider och uppkomsten av byggavfall. Målet har varit att optimera ställtiderna och minimera byggavfallet. Metoderna som ansågs vara lämpligast för studien var intervjuer, framtagning av statistik samt observationer. Detta genomfördes på två av Botrygg ABs byggarbetsplatser med specifikt fokus på platsen Kv. Duvkullen. Intervjupersonerna representerade inköp, logistik, plats -och byggchef. De uppnådda resultaten sett till olika moment i avfallshantering och planering mot ställtider gav möjlighet att dra slutsatser mot vad Botrygg AB kan göra för möjliga ändringar för en förbättrad produktion sett till kostnader, tidseffektivisering och ge en reducerad miljöpåverkan. Framtagna resultat är statistik av byggavfallet vid en av byggarbetsplatserna, intervjupersonernas resonemang och åsikter kring de två berörda frågor, sett till vad som kan göras bättre samt vad som i nuläget fungerar. Dessa resultat jämfördes och följande slutsatser kunde dras: närmare samarbete med leverantörer, vidareutveckla Just-in-time, kontinuerlig kommunikation mellan berörda aktörer, uppföljningar av projektens byggavfall för att se vad som genereras, sätt upp ett tydligt mål om mängder byggavfall genom att t.ex. använda statistik.

Detta är ett examensarbete på 22,5 hp för högskoleingenjörer i innovationsteknik och design. Arbete tilldelades av Camatec Industriteknik AB i samarbete med Barilla Sverige AB. Projektet gick ut på att utveckla regleringsmöjligheterna för en av Barillas borststationer som borstar bort överflödigt mjöl från brödkakorna efter bakning. Idag är problemet att det tar lång tid och är mycket omständigt att göra en enkel reglering och det vill Barilla komma ifrån. Önskemål från Barilla var att kunna applicera den nya lösningen till flera maskiner då det finns liknande problem på andra produktionslinor. De metoder som använts under examensarbete är väl beprövade metoder inom produktutveckling. Dessa metoder har studerats och tillämpats under utbildningen gång och är därmed väl beprövade. Metoder som idégenerering, elimineringsmatriser och konstruktionsteknik är några av de som används i detta projekt. En teoretisk ställtidssimulering har tagits fram för koncepten för att kunna se om koncepten lyckats minska ställtiderna. Kostnadskalkyler för de främsta koncepten togs också fram för att kunna jämföra konceptens kostnad och dess simulerade omställningstider. Detta för att kunna ta ut ett bra koncept att jobba med. Den nya produkten har visat sig ge en minskad teoretisk ställtid med hela 43%. Detta då en minskning av andelen skruvar som måste lossas för att kunna göra omställningen, samt att de skruvar som var svåra att komma åt är nu lättåtkomliga, precis som Barilla önskat. Vid en omställning av den nya maskinen kan alla skruvar lossas från utsidan av sidoplåtarna. Den nya maskinen kommer att underlätta för operatören då alla skruvar som måste lossas innan en omställning kan göras är placerade på utsidan av gavelplåtar. Detta betyder att operatören inte behöver komma åt skruvar som är placerade på trånga och svåråtkomliga ställen. Den nya produkten har även standardiserats genom att enbart använda en typ av mutter. Detta gör att operatören inte behöver mer än ett verktyg för att göra en omställning av maskinen. / This project for students in Innovationsteknik och design, 22,5 ECTS credits is the final process of the education. This project has been assigned by Camatec Industriteknik AB in cooperation with Barilla Sverige AB. The project is all about to make it easier to make changeover on one of Barillas brushing machines. One of their requests was that the final solution could work on more than just one of their machine. The methods that has been used in this project has followed the product development methods that been a large part of the education. Processes like brainstorming, failure mode and effects analysis and two difference elimination matrix to choose a concept, this are some of methods that has been used in this project. To ensure that best concept is chosen the concept is tested in a theoretical changeover simulation to see if the changeover time has been reduced. There was an estimate of cost that was made in this project. Both the simulation and cost is compared to each other. Out of this result the best concept could be made. The new product has shown result from the theoretical changeover simulation that the changeover time has been reduced by 43%. The amount of bolts and nuts that need to be loosened to obtain a changeover has been reduced. The client ordered a new technical solution that will make it easier to make a changeover, by reducing the nuts that was hard to reach and make it possible to just loosened everything from the outside of the endplate the request has been solved. The new product will make it easier for the operator to make the changeover and adjust the machine. The biggest change is that all the nuts or bolt that you need to released to make a changeover is now located on the outside and the endplate. That means the operator doesn’t need the extra effort to get to the nuts or bolts that are hard to reach. The new product is only using one type and bolts and nuts which means that the operator only need one tool to make the changeover. This will reduce time and make it easier for the operator.

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented. Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production. To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events. The purpose is to present the objective cold figures that show the use of capacity for all machines and totally. The compilation of the seven CNC cutters shows that the use of capacity reaches 33 %. The lack of machine operators is the single largest reason, 45 % of the total use of capacity. The set up time reaches 6 % totally of the 36 hours of observation of the machines. The study of the separate CNC cutters shows that the result follows the result of the compilation of all machines; the main reason why the use of capacity is low depends on the lack of machine operators. This means that if the demand increases there will not be enough operators to meet this demand. If using SMED, the set up time percentage share of the total use of capacity are too large, but the production of prototypes that supplies great value to the company may justify the set up times. By using Total Productive Maintenance (TPM), based on the elimination of breakdowns and defective products, the stability in production and the use of capacity may increase.
