Examensarbete Flödesanalys och processförbättring vid Nautor Frank Enqvist Examensarbete för ingenjörsexamen (YH) Utbildningsprogrammet för produktionsekonomi Vasa 2017 EXAMENSARBETE Författare: Frank Enqvist Utbildning och ort: Ingenjör (YH), Vasa Inriktningsalternativ/Fördjupning: Produktionsekonomi Handledare: Mikael Ehrs, Tomas Halmesmäki Titel: Flödesanalys och processförbättring vid Nautor _________________________________________________________________________ Datum: 19.4.2017 Sidantal: 43 _________________________________________________________________________ Abstrakt Uppdragsgivaren för detta examensarbete är Nautor. Nautor är beläget i Jakobstad, Finland och dess produkter exporteras över hela världen. Företaget är ett av de ledande företagen i världen på tillverkning av segelbåtar i lyxklass. Syftet med arbetet är att utreda problemen i Nautors interna logistik med hjälp av en flödesanalys, och sedan ge förslag på lösningar till de problem som framkommer under analysen. Flödesanalysen ger en uppfattning av hur viktigt det är att i en produktion ha ett bestämt flöde, och hur kraftigt detta kan påverka effektiviteten inom produktionen. Problemen som uppstår löses sedan med hjälp av Lean tankesätt och olika lösningar baserat på Lean metoder. Resultatet av arbetet är en lista av de problem som uppdagats, tillsammans med lösningar och standardiserade flöden. Vidare presenteras ett Lean baserat pilotprojekt med daglig planering inom en del av produktionen. _________________________________________________________________________ Språk: Svenska Nyckelord: Flödesanalys, Processförbättring, Lean _________________________________________________________________________ BACHELOR’S THESIS Author: Frank Enqvist Degree Programme: Bachelor's degree Specialization: Industrial management Supervisor(s): Mikael Ehrs, Tomas Halmesmäki Title: Process Mapping and Process Improvement at Nautor _________________________________________________________________________ Date: 19.4.2017 Number of pages: 43 _________________________________________________________________________ Abstract The client of this thesis is Nautor. Nautor is located at Pietarsaari, Finland and their products are exported worldwide. The company is one of the leading companies in the world producing sailing yachts. The purpose of this work is to investigate the problems within Nautors production, this is done by mapping the process. Then the purpose is to further give suggestions on how to solve the problems that might occur. Flow analysis gives an idea of how important it is in a production to have a certain flow and how this can facilitate the production efficiency. The problems that occur is later solved with Lean thinking and methods based on Lean systems. The result is a list of problems found in the production presented together with solutions, and a standardized process within the production is presented. Later a suggestion with daily planning is presented together with a result. _________________________________________________________________________ Language: Swedish Key words: Process mapping, Process improvement, Lean _________________________________________________________________________ Innehållsförteckning 1 Inledning .............................................................................................................................................. 1 1.1 Bakgrund ..................................................................................................................................... 2 1.2 Problembeskrivning ................................................................................................................ 2 1.3 Arbetets syfte ............................................................................................................................. 2 1.4 Avgränsning ................................................................................................................................ 3 1.5 Disposition .................................................................................................................................. 3 1.6 Centrala begrepp ...................................................................................................................... 4 2 Företaget .............................................................................................................................................. 5 2.1 Historia ......................................................................................................................................... 5 2.2 Nautor idag ................................................................................................................................. 5 3 Teori ...................................................................................................................................................... 7 3.1 Flödesanalys ............................................................................................................................... 7 3.1.1 Varför genomför man en flödesanalys?
