Implementering av Lean genom TAK och SMED

This graduation work is a result of implementing Lean Production using OEE and SMED at Enics Sweden AB in Malmö. Enics doesn?t have an established improvement concept and therefore should this work serve as an introduction to possibly start with Lean Production. A result in this report is that an OEE value has been identified within a common order at Enics. Other results are that an implementation of a Lean-board has been implemented and furthermore, within SMED, a flag that indicates changeover..

Lean Construction applicerat på betongkonstruktion : The Last Planner och visuell metodik för reducering av produktionstidsvariationer

Bakgrunden till detta examensarbete är byggföretagens utmaningar med att bedriva byggprojekt där nya och unika objekt skall konstrueras, med många nya förutsättningar och allt som oftast även en ny sammansättning av personalstyrkan. Ett gemensamt behov för dessa byggprojekt är att effektivt kunna hantera en mängd av olika och nya variationer.Oden anläggningsentreprenad AB presenterade ett problem gällande oönskade variationer av produktionstider för betongmonoliter som innefattar mycket repetitiva arbetsmoment. Examensarbetets syfte blev att besvara följande frågor:Vilka är faktorerna som påverkar variationer i produktionstiden vid bygget av betongmonoliter?Vilka är lösningarna till att reducera faktorerna som negativt påverkar produktionstiden?Hur ska de nya lösningarna implementeras?I examensarbetet har teorier kring lean production, Lean Construction, organisationsförändring och betongkonstruktioner undersökts. Det empiriska materialet har hämtats genom att författaren deltagit i produktionen och fört en fältdagbok över dagliga problem som produktionspersonal påtalat.

Lean som styrmodell i offentlig sektor : en kvalitativ fallstudie av kommunala förvaltningar i Växjö

Lean har ökat i populäritet inom den offentliga sektorn men den forskning som finns om lean i detta sammanhang är fortfarande begränsad. Syftet med uppsatsen är att analysera hur lean tillämpas i svensk offentlig sektor och om lean är en meningsfull satsning försvenska kommuner. Detta görs genom en kvalitativ fallstudie där vi intervjuar medarbetare på två kommunala förvaltningar i Växjö kommun. Analysen jämför datan med 14 principer som leankonceptet bygger på och diskuterar speciella förutsättningarför lean i offentlig sektor. Leansatsningen ställs i relation till effekterna av lean hos verksamheterna.

Lean Construction i teori och praktik

Höga byggkostnader, kvalitetsproblem, dyra kostnader för omprojektering och låg lönsamhet för entreprenörer är exempel på problem inom byggbranschen. Statistik pekar på att byggkostnaderna för att producera byggnader har stigit kraftigt under de senaste åren. Byggnadsentreprenörer har börjat utveckla alternativa metoder för att genomföra kostnadseffektiva projekt. Denna studie kan delas upp i två delar, en teoretisk och en empirisk del. Den teoretiska delen utgörs av litteraturstudier för att få djupare kunskap och förståelse om Lean konceptet. Den andra delen avser en empirisk studie.

Studien ämnar vidare undersöka vilka faktorer som påverkar utfallet samt undersöka hur Lean har påverkat effektiviteten på stationerna. För att besvara detta har intervjuer genomförts med personal på OKQ8. Studien analyserar hur faktorer så som stress, arbetskraftsflexibilitet och delaktighet har påverkat utfallet av implementeringen. Vidare har även nyckeltal använts för att analysera om Lean har lett till att organisationen har blivit mer effektiv.

Flödesoptimering på sjukhuslaboratorium: En praktisk implementering av lean

This study has investigated the possibilities of implementing lean in a division of a hospital in Stockholm. The goal was to reduce the lead time for the patient to get his diagnose by implementing lean in the two production flows of this division. In order to accomplish it, a complete map over the value stream has been done. With the help of the value stream map and lean theory a list over the processes in contradiction with lean has been made. Finally propositions to implement lean and by this way reduce the lead times in this stream have been made out.

En sjuk arbetslinje? : En studie av rehabiliteringskedjans hälsoeffekter

This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.

Turbuhaler - Kvalitetskontroll : En kvalitativ studie av årets Leanpristagare

Problem: How is Lean, a production-focused model being applied to non-productive focused industries.Purpose: To examine how Lean has been applied to the department of Turbuhaler-Kvalitetskontroll and which parts have been successfully applied.Problem statement: How does the implementation of Lean?s basic concept, which originated in the car industry, differentiate itself from the implementation of Lean in the pharmaceutical industry, in this case the department of Turbuhaler-Kvalitetskontroll at AstraZeneca.Conclusions: The department has had success in its implementation of lean. They have developed and modified the basic concept in order to apply it and excluded the parts they did not consider necessary. Through their work they have accomplished numerous improvements in, among other things, the reduction of lead time. .

Effektiv Planering enligt Lean Production : En fallstudie på Sandvik Mining and Construction

Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.

Visuell planering enligt Lean : Optimering av samordning i syfte att höjakvaliteten i grundläggningsprojekt

Construction production always contains different disciplines whose priorities andinterests can be very diverse. Good communication and coordination are essential tominimize misunderstandings and achieve good quality in the end result. This makesplanning a central part of the production management. In a world where conditionscan change as often as daily, being well prepared increases the opportunities to stayflexible and decrease negative effects of the changes.This study has been done in association with Skanska Foundations district North inStockholm in order to investigate how visual planning can be used in the productionmanagement to optimize the coordination and the quality.The history of Lean started at Toyota, but the concept are now spread over theworld and are used wide outside of the car industry nowadays. What?s challengingabout Lean in foundation projects is to embrace a long-term perspective and invest insolutions that are profitable in the longer term, instead of solve problems by onlytreating the symptoms.A holistic perspective is crucial in order to truly understand Lean.

Ledarskap och relationer vid implementering av lean i sjukvården: en utveckling av yrkesidentiteten

The aim of this case study was to investigate the role of leadership and interpersonal relations among staff during implementation of lean at a University Hospital in Sweden. The 15 respondents were leaders and staff members from different wards and clinics, who had started working according to lean principles. One of the methods used was explorative, low structured interviews. Other methods used for gathering information about the case was attending lectures about lean healthcare at the hospital, part-taking in the lean game and reading articles about lean and the implementation in both daily press and on the intranet of the hospital. The results showed that an open and accessible leader that coaches his/her staff and supports their work, helps the staff to develop a lean identity.

Från frihet till fängelse: En studie av klientflödet på Häktet Kronoberg

In the last decades, lean production has proven to be one of the most important organizational paradigms in manufacturing. The lean concept has also spread into the service industry where it is applied within a range of different areas. The wide applicability of lean principles has spurred the authors of this study to apply the principles in the context of the operations of a Swedish remand prison. The thesis examines the process a client of the remand prison Häktet Kronoberg goes through from the time of arrest until he/she is released or convicted and transferred to jail. Based on lean tools and principles, the thesis maps and analyses this process.

Planering & produktionsstyrning : Lean filosofin vid produktion av asfalt

Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.
