Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper Mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the Mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper Mill? We have found that the problems are strongly connected to the low amount of information sharing between the Mill and the suppliers.

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the Mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling Mill was actually designed for rolling low carbon steel.

This paper is a case study on Bradley E. Manning, famous for leaking classified intelligence to media, or in the charge sheet?s words: ?knowingly give intelligence to the enemy, through indirect means.? My opinion is that this sort of dilemma is a question of values, how you view the world and, most important of all, human rights and the philosophy of rights. Therefore I decided to sort out the arguments regarding the issue of freedom of speech versus the state?s need for protection.

This study was made for the round wood transport company MT Transport AB. Time studies were made in order to analyze time consumption on the Mill site for timber trucks delivering round wood at the Södra Cell Mörrum Mill. The most interesting was to see how much of the time spent at the factory that was waiting time. In three weeks the study was going on and the drivers were clocking it themselves..

During the summer 2007 was a scrubber tested at Gruvön papper Mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. One possible solution is to clean the scrubber liquid in Gruvön biologic cleaning construction.Microorganisms in the biologic cleaning construction need to assimilate nitrogen. There are environments free from oxygen in the cleaning construction.

The purpose of this study is to explain how the value of sawn wood changes when sawn wood are cut in 30 respective 60 cm lengths. The raw material into the saw Mill will mainly be bucked in 30cm and 60 cm modules. There will also be two alternatives where the timber will be bucked special lengths, 370, 490 and 550 cm but also in 490 and 550 cm.The method used for the study is to simulate both cutting and sawing the woods. For cutting the simulator Timan is used and for sawing the simulator Timberopt is used. When data is generatedfrom the simulators, calculations of some key figures is done and also how much the revenue need to be increased for the sawn wood in order to cover for the increased costs of changing sawn woodfrom 30 cm to 60 cm modulesThe conclusion is that the single biggest reason, impacting the value of the sawn wood is the cutting at the saw Mill.When going from 30 to 60 cm modules, the impact will be that the customers to the saw Mill must pay more to increase the revenue by at least 10% for the sawn wood in order to justifice the changein production.It is also possible to increase the value of the products further by bucking the timber in three lengths, 370, 490 and 550 cm, in order to get 12 % increase of the share of longer sawn wood (>= 480 cm)..

By Analyzing the data & the data through the visits and the interviews, this Research Project Has Been Combined to give in-depth knowledge about the Activities Which merchandisers performer in a Mill and into buying a house..

The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.

Title: Bottleneck management through materials administration Course:  4FE05EAuthors:  Mikael Karlsson and Johannes Mueller  Examiner: Helena ForslundKey words:  Bottleneck management, material management, process description, timber, proceduresPurpose:   The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing Mill to keep a continuous  flow, and thereby minimizing the risk for production stops at LB-Hus.  Part.  1:  Identify  and  analyze the material management  connected to  the planing Mill  in order to identify problem areas.Part.2:  Identify  improvement potential  in the material management connected to the planing Mill.  Part.3: Suggest improvements in the material management connected to the planing Mill. Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions.Empirical foundation:  Interviews carried out at LB-House,  illustrated with the help of process maps and a description of each process.  Conclusions:  To work with  the  suggestions  given  and  to  follow  clear procedures  in  all  processes would  result in  a more  efficient  inventory management,  it would also present  a  solution  to  the problem regarding the planing Mill being a bottle neck.Suggestions for further research: Review and map the information flow from demand to production start.

Hallstaviks paperMill is an industry plant within Holmen Paper. Hallstavik is a mechanical Mill and produce newspaper and journal paper. During year 2000, Hallstavik used approximate 1.200 m3f spruce, either as logs or chips from sawMills. Due to that the production is running continuously the Mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper Mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper Mill work. Study 2 was a survey among people with experience in assessing the posture of paper Mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

An often encountered problem when implementing a mass flow regulator in a rolling Mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling Mill.
