Purpose - The purpose of this study is to examine how a warehouse of finished goods can be made more effective with warehouse design, warehouse control, new technologies and how the current way of work must be adjusted to the new technologies. In order to achieve the purpose of the study, the writers had two research questions connected to the purpose. Method - A case study has been conducted as research strategy in collaboration with Smurfit Kappa AB. The study began by researching possible theories that could be relevant to the study. This was followed by an empirical study where interviews and observations were carried out. Documents with floor plans have also been studied to understand the current state of the warehouse. The empirical findings have been compiled, discussed, and compared to the theoretical findings. Results - At the time of the study, the warehouse house of finished goods did not have a system for storing goods. They also do not have an ERP-system and therefore the communication possibilities are limited. The company will implement an ERP-system and barcode scanners in the future which makes it possible to improve the efficiency of the warehouse with design, control, layout, zones, scanners, and standardize movement. There is also new finding of wastage that can be controlled. Findings - Even though the case company of this study can achieve improved efficiency in the warehouse by using the management methods and tools presented in this study, the most important part is to provide the employees with the right information. Thereafter the management methods and tools such as zone sectioning, barcode scanners, and standardized create more effectiveness. In addition to previous findings, two new forms of waste that can occur in a warehouse has been identified. Research limitations - Because of the decisions made by the case company of future implementation of barcode scanners, the researcher felt that there were limitations to the possible improvement proposals. If the researchers could have proposed a different tool, the outcome of the work could have looked different. If there were more interviews or several business cases the generalization it would strengthened the case study. / Syfte - Syftet med detta examensarbete var att undersöka hur färdigvarulagret kan effektiviseras med hjälp av lagerutformning, lagerstyrning och ny teknik och hur arbetssättet måste anpassas till den nya tekniken. För att kunna uppnå syftet med studien har författarna två forskningsfrågor som stöd för att uppnå effektivitet. Metod - För att besvara studiens syfte samt frågeställningar har författarna utfört en fallstudie som undersökningsstrategi på Smurfit Kappa AB. Studien började med att undersöka vilka befintliga teorier som kan kopplas till arbetet. Därefter genomfördes observationer och intervjuer på fallföretaget. Författarna fick även ta del av ritningar för att få förståelse av det nuvarande flödet. Empirin har sedan sammanställts, diskuterats och jämförts mot det teoretiska ramverket. Nulägesbeskrivning - Fallföretagets färdigvarulager använder i dagsläget inget system för lagring av artiklar. De har heller inget affärssystem vilket gör att information inte kan kommuniceras ordentligt. Företaget ska införa ett affärssystem och streckkodsläsare. Detta gör att det finns möjligheter att effektivisera färdigvarulagret. Resultat - Företag kan öka sin effektivitet med hjälp av flera metoder, principer och verktyg. Författarna tror dock att det viktigaste är att medarbetarna får tillräckligt med information för vad som ska göras. Därefter kan olika utformningar och styrningar som layout, zonindelning, streckkodsläsare och standardiserade arbetssätt anpassas för att få ett effektivt färdigvarulager. Utöver detta har två nya slöserier som kan förekomma i ett färdigvarulager identifierats. Begränsningar - Då fallföretaget som undersöktes redan bestämt sig för vilket affärssystem och vilket verktyg som skulle användas i lagerverksamheten, i detta fall streckkodsläsare, upplevde författarna att det fanns begränsningar vid framtagning av förslag på förbättringsåtgärder. Om verktyg inte redan bestämts hade andra lösningar kunnat presenteras. Om studien hade fler intervjuer eller jämförts med fler fallföretag hade generaliseringen ökat.

I dagens samhälle med en växande marknadsglobalisering och snabbt föränderlig marknadsmiljö är det viktigt att företag driver sina logistiska processer på ett effektivt sätt för att bemöta kundernas behov, hålla kostnaderna nere och bibehålla en konkurrenskraftig position. Lagrets utformning har stor påverkan på effektiviteten i hanteringen av artiklar och ett välskött lager kan minska leveranstiderna, öka kundnöjdheten och minska kostnaderna. I många företag används stora resurser på saker som inte tillför något värde. Syftet med denna studie var att undersöka och identifiera problem inom lagerhantering genom en egenutvecklad modell. Studien syftar också till att utvärdera och identifiera förbättringsförslag som kan effektivisera lagerhanteringen. Tre frågeställningar utvecklades för att tydliggöra för läsaren att studien fördjupat sig i lagerhanteringsaktiviteter som sker på lagret. Studien använde en kombination av kvalitativa och kvantitativa metoder för att uppnå en djupare förståelse av resultaten. Intervjuer, observationer och viss uträkning har använts för att undersöka lagerhanteringsaktiviteter. Undersökningen visade att det finns åtta aktiviteter på lagret som är viktiga för effektiviteten och att det uppstår slöserier i sex av de åtta aktiviteterna på det undersökta företaget. Modellen har hjälpt studien att komma fram till vilka lagerhanteringsaktiviteter som bidrar till icke-värdeskapande slöserier. Onödig bearbetning och väntetid uppstår i godsmottagningen, transport i ompaketering, transport och onödiga rörelser i inlagringen, lager, onödiga rörelse och överproduktion i lagring, transport och onödiga rörelser i orderplock samt väntetid vid utleverans. Resultatet i denna studie bringar klarhet i olika förbättringsförslag som kan minimera slöserier för att effektivisera lagerhanteringen. Studien visar att företaget kan minska transporttiden, hitta artiklar enklare, undvika onödig bearbetning samt minimera onödiga rörelser. / In today's society with growing market globalization and a rapidly changing market environment, it is important that companies run their logistics processes efficiently in order to meet customer needs, keep costs down and maintain a competitive position. The layout of the warehouse has a significant impact on the efficiency of handling items, and a well-managed warehouse can reduce delivery time, increase customer satisfaction, and reduce costs. In many companies, large resources are spent on things that add no value. The purpose of this study was to investigate and identify problems in inventory management through a self-developed model. The study also aims to evaluate and identify improvement proposals that can make inventory management more efficient. Three questions were developed to make it clear to the reader that the study focused on inventory management activities that take place in the warehouse. The study used a combination of qualitative and quantitative methods to achieve a deeper understanding of the findings. Interviews, observations and some calculation have been used to investigate inventory management activities.The investigation showed that there are eight activities in the warehouse that are important for efficiency and that waste occurs in six of them at the investigated company. The model has helped the study to determine which inventory management activities contribute to non-value-added waste. Unnecessary processing and waiting time occurs in goods reception, transport in repackaging, transport and unnecessary movements in storage, warehouse, unnecessary movement and overproduction in storage, transport and unnecessary movements in order picking and waiting time at delivery. The results of this study bring clarity to various improvement proposals that can minimize waste in order to make inventory management more efficient. The study shows that the company can reduce transport time, find products more easily, avoid unnecessary processing and minimize unnecessary movements.

In recent years, Hallsta Paper Mill has experienced significant changes in the demand for paper. The ordershave become smaller and more customer-specific, while the graphical paper industry has steadily declined.As a result of these changes, the employees at Hallsta Paper Mill feel that the finished goods warehouse isno longer optimally designed, and they have identified that waste occurs in the warehouse. Therefore, thepurpose of the study was to provide suggestions on how the activities in the warehouse could become moretime-efficient and investigate how the finished goods warehouse could be designed to suit today’s demandbetter. To facilitate the answering of the purpose, three research questions were formulated: What areas ofimprovement exist in the finished goods warehouse regarding its activities and layout? What effects can beobtained by addressing the identified areas of improvement? and What solutions are recommended for thefinished goods warehouse at Hallsta Paper Mill? The study’s first research question was answered by conducting interviews, a spaghetti diagram, and ananalysis of produced paper rolls. The interviews were conducted with employees who either workoperationally or administratively in the warehouse to get a comprehensive picture of how the work isperformed and where waste occurs within the activities. The spaghetti diagram identified the movementpattern for the trucks in the warehouse and provided indications if unnecessary long transports occurred ornot. The analysis of produced paper rolls examined how well the storage compartments in the finishedgoods warehouse were dimensioned based on today’s demand. Based on the collected data, nine areas ofimprovement were identified, seven areas linked to the activities in the warehouse and two areas linked tothe layout of the warehouse. After the areas of improvement were identified, the study’s second research question was answered bydeveloping solutions within each area of improvement. To develop the solutions linked to the activities inthe warehouse, root cause analyses were performed, where each area was examined to find the root causeof the problem. For the solutions linked to the design, inspiration was instead taken from the warehouselayout and article placement literature. A total of 23 solutions were developed, 19 linked to the activitiesand four linked to the layout. For each solution, it was then analysed what effects an implementation of thesolution would provide, focusing on possible time savings. The effects were analysed with help from theliterature and the authors’ knowledge of logistics. After the effects had been analysed, each solution was assessed based on the effects identified in theprevious research question. The solutions were placed in effort-impact diagrams based on how much effortis required to implement the solution and how much impact is expected from the solution. When assessingthe impact, extra consideration was given to possible time savings, as it was the highest priority accordingto the directives from Hallsta Paper Mill. The assessment then resulted in a recommendation on how thesolutions should be approached. The less effort required and the more impact a solution would bring, thehigher priority was given to the solution. To summarise, two solutions were recommended to beimplemented immediately, nine solutions should be implemented in a second step, seven solutions shouldbe considered and investigated further, and two solutions should be rejected. The solutions aimed to makethe warehouse activities more time-efficient and suggest how the warehouse could be designed to suittoday’s demand better.
