Effektivisering av materialflöde via lagerlayout : En fallstudie på ett mindre underhållsföretag
Sammanfattning: Purpose - The purpose of this study is to evaluate the non value creation which can occur within smaller maintenance companies’ warehouses. Utilizing a status analysis potential solutions as well as deficiencies will be found. Two issues have been created to answer the purpose; they are. Which parameters are vital for a well-functioning warehouse connected to smaller maintenance companies’? What aspects are important to take into consideration for restructuring of a warehouse layout for smaller maintenance companies’? Method – A pre-study was conducted at the case company, a smaller maintenance company for vehicles, to create a greater understanding of the company's problem area. In order to answer the two issues due to the purpose of this study, a case study was conducted. The case study consisted of a literature study, an interview, an observation and a document study. Six interviews were conducted with seven respondents to study the case companies current and preferred state. Two observations were conducted, of which one is the basis for a spaghetti-diagram the other was used to ascertain the collected data coincided with reality. Results – The choice of strategies and principles is of significance for a well-functioning storage, a combination of multiple principles is preferred also for smaller maintenance warehouse set storage location is preferable since it enables a well-known storage layout for the coworkers. This in turn creates non value creation activities can be reduced. This, in combination with classifying articles in the shape of an ABC-analysis, family groups, modern storage layout, popularity and similarities etc. Furthermore, a correct removal of articles is essential for a well-functioning storage. Utilizing a company's work power can result in non value creation activities being reduced or be used more efficiently, this being one issue for the case company. There are multiple aspects to consider during restructuring of a storage layout. Knowledge of the product which is being stored and what will potentially be stored is essential for the company. By identifying articles, the company will be able to create a new storage layout. A maintenance company should to execute an ABC-analysis and a Kraljics matris to create an overview of what is being stored. When choosing storage methods, strategies and principles are complimentary to each other and the company's internal functions. For smaller maintenance companies’ storage has restrictions regarding storage space which in turn necessities thorough survey of articles. Implications – The case study is based upon well-known theories within the subject of logistics and warehousing. New theories are not presented in the study; the authors however consider finding a lack of how the existing theories can be linked to warehousing operations for a maintenance company. The conducted study can be replicated in terms of work, however, the chosen strategies and principles are selected specifically according to the circumstances of the case company. Whit theory as a pillar it has justified why the material flow is not optimal and which theories are considered to be compatible with the case company. Limitations – The study was conducted as a one-case study. If the study had instead involved more companies, it had resulted in a multiple-case study which had generated in increased generalizability in the case study. The case study is limited to the internal material flow on the case companies warehouse. A larger number of interviews and observations could have led to increased reliability, as common deficiencies and potential solutions had resulted in greater credibility.
