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.

Titel: Value Stream mapping in practice ? A case study at Light MyFireAuthors: David Rydman and Tomas ÖnnemarMentor: Veronica Ülgen SvenssonExaminer: Åsa GustafssonBackground: Companies push their prices in today's markets to be competitive, which means that companies need to find ways to reduce costs while maintaining profits. (Cudney, 2009) According to Bergman and Klefsjö 2007, the basic rule of quality improvement says "there is always a way to achieve higher quality at a lower cost". One way is to improve a company's processes to get a more efficient flow and improvements that may cut costs. (Bergman & Klefsjö, 2007) Why it's important to look at the processes are that they often contain waste that can be eliminated.

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to Streams, thereby reducing the eutrophication of lakes and seas. The agriculturalStream Lillån, a tributary to Stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from Stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural Stream and from a nearby smaller Stream. Retention in the Stream was suggested to decrease along with the nutrient concentration in the water.

Den planerade gasledningen Nord Stream, eller ?den ryska gasledningen?, har varit föremål för enintensiv debatt sedan hösten 2006 i såväl pressen som i riksdagen. Debatten har spänt över ett brettfält där miljöhänsyn och säkerhetspolitiska aspekter har avlösts av inlägg rörande Sverigeshandlingsfrihet inom ramen för internationella havsrättsliga avtal och hur Nord Stream skahandläggas för att denna handlingsfrihet inte ska begränsas inom ramen för svenskförvaltningslagstiftning.Föreliggande arbete analyserar debatten runt Nord Stream från det att projektet presenterades påvåren 2005 och fram till den särskilda debatt som hölls i riksdagen samma dag som Nord StreamAG inlämnade sig ansökan om miljöprövning till regeringen. Källmaterialet har hämtats fråndebattsidorna i Sveriges två största morgontidningar samt från riksdagens kammare och därefteranalyserats med en argumentationsanalytisk modell enligt Arne Næss..

The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small Stream. The samples were taken in a small Stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upStream and downStream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the Stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.

Big dangerous Russia, environmental thief or house warmer? The Nord Stream pipelines are a highly debated theme in Europe and the EU. A number of different countries will be subject to the pipelines direct or indirect. This paper aims to figure out what kind of threats and possibilities Denmark, Finland, Sweden and Germany consider to be the consequences with the pipelines.The study takes as a standpoint the area of security studies and the widened of the same. The three standpoints within the security study that will be used are military security, environmental security and energy security.

Value Stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value Stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value Stream analysis on production and planning.

Volvo Penta has been producing boat engines since 1907 and are world leading in this seg­ment. They have today an extended range and also sell industrial power stations. Quality, safe­ty and environmental care are three core values for Volvo and together they strive to give their customers the right product with the right quality.Volvo has developed a production system named Volvo Production System, VPS, and one of the pillars is continuous improvements. Within this pillar you can find value Stream map­ping, which is used to analyze the value Stream through the process. This tool gives a wide perspective and helps to keep focus on the entire process instead of just parts of it.Volvo Penta in Vara has earlier done value Stream mapping but without good results since they didn?t take set-up times and imbalances in account.

För att beräkna de kostnader som uppstår i produktionen använder VCBC produktkalkyler. Representanter vid VCBC anser att företaget har problem med höga plåtlager, överproduktion samt problem med att se kostnadssamband. Ett value Stream där förbättringsmöjligheter finns är Flöde 1 vid VCBC.

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating Stream crossings with minimal harm to the Stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the Streams had been crossed concerning the number of crossings, visible damage to the Stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the Stream and amount of large woody debris in the Stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

Headwater Streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of Stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and Stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different Stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the Stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish Streams. Dead wood are an important structure for the biodiversity in forest Streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the Stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.
