Detta är en magisteruppsats i arbetsvetenskap utförd under vårterminen 2014. Studiens syfte har varit att undersöka arbetsmotivationen bland anställda i en tillverkningsfabrik som implementerat principer och verktyg från lean production. Utgångspunkten har varit att undersöka om element i lean production, så som teamorganisering och delaktighet, har en positiv inverkan på inre motivation. I studien operationaliserades inre motivation som arbetstillfredsställelse och engagemang.     Studien utgår från en kvalitativ ansats med ett hermeneutiskt perspektiv. Datamaterialet har insamlats från sammanlagt 12 respondenter, samtliga från samma fabrik i Svealand.

Generally in Macedonia keeping farm records and farm business planning is not often practiced like an ordinary activity in farming. Therefore one of the crucial things to do it is to comprise and continuously practice record keeping of farm data. The efficient and justified farm business planning should be based on farm records about the previous work of the farm, which will bring a structured approach for planning all the activities, as well as provide a good basis for attracting investors and creditors for the additional expansion of the business.Given that sheep breeding holds an important part of the livestock production in Macedonia, there is a need for adding analytical sheep enterprise budgets to support the farm business planning process at sheep farms.The aim of this research was to develop sheep enterprise budgets created on the best production practice for Macedonian conditions of breeding and test their applicability into the farm business plan model Agriwise Macedonia. The sheep budgets were composed with a process of data collecting consisted of direct farm data (for the cases), expert's consultation and relevant desk research, as well as a literature study. The aim of doing it was to attain more accurate calculations of the enterprise budgets, which will result in a more precise outcome in the farm business plan model Agriwise Macedonia.

Large areas have been ditched in Sweden during the past 100 years to improve the forest production. Ditching and also maintenance of old ditches are operations having mainly negative effects on water quality, flora and fauna and changing characteristics of soil. The purpose of this study was to suggest a method for inventory of the need for ditching maintenance in old forest ditches that takes biodiversity, water protection and forest production into consideration. Inventory methods from five Swedish and Finnish forest companies, agencies and organisations were compared. Their employees were interviewed about their handling with ditches, forest production and nature conservation.

Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household waste, slaughterhouse waste and liquid manure. Other than biogas production, the possible treatments for organic household waste and slaughterhouse waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders.

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts.

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.

AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.

The purpose of this essay is to apply Activity Based Costing on a Service and Support function in order to identify and allocate costs for providing support for IT deliverables..

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

The purpose with this bachelor thesis is to identify risks and insufficiencies concerning the production at WilloMaskin AB. The project is limited to only 4 machines, where theories as ?OEE? (overall equipment efficacy) should be illuminated and analyzed. The theory of ?Single Minute Exchange of Die? is also presented.The method used in this project is mostly based on qualitative studies but also quantitative studies are presented.

In this report presents a thesis by Frida Altskog performed in collaboration with Askersunds Kakelmakeri. The project?s goal has been to produce a ceramic ledge after the company?s specifications. The company?s desire and production facilities have been in focus.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

I och med den tillväxtprognos som Göteborgs Stad har så kommer även godstransporterna attöka. Syftet med studien är därför att identifiera slöserier i kommersiell godstrafik med hjälp avLean Productions 7 + 1 slöserier. Slöserierna skall sedan anpassas för att kunna framställas i enLeanbaserad slöserimodell för den kommersiella godstrafiken. Dessa kommer sedan teoretisktatt effektiviseras eller elimineras. Tillvägagångssättet har bestått av kvalitativa observationer,intervjuer samt teoriinsamling.Lean Production är ett produktionssystem och synsätt framtaget av Japanska företaget Toyota.Dess två huvudprinciper är att företagen alltid ska respektera människor och sina medarbetaresamt ständigt jobba med förbättringar för att bli så effektiva och produktiva som möjligt.Förbättringarna sker i form av att identifiera Leans 7+1 slöserier för att därefter reducera ellereliminera dem.Studiens resultat är häpnadsväckande hur ineffektiva vissa transporter är.
