Utformning av operatörsverktyg för åskådliggörande av rörliga kostnader

Syftet med detta arbete som utförts på Kvarnsvedens pappersbruk i Borlänge har varit att framställa ett operatörsverktyg. Ett operatörsverktyg som ska åskådliggöra processens rörliga kostnader, som kan benämnas en produktkalkyl för stunden. Verktyget skall senare möjliggöra förbättrade utsikter för kontroll, styrning och uppföljning av rörliga kostnader inom företaget samt öka möjligheterna till att minska de rörliga kostnaderna som är kopplade till processen. Massafabriken på Kvarnsvedens pappersbruk och pappersmaskin 11 har utgjort arbetets grundläggande måltavlor för operatörsverktyget. Arbetet innefattade kartläggning och granskning av pappersprocessen för att skapa en så heltäckande bild av uppdragsbeskrivningen som möjligt. När processen studerats och processflöden kartlagts mer ingående påbörjades utvecklandet av operatörsverktyget. Vidare utfördes en litteraturundersökning för att urskilja potentiella handlingsalternativ vid utformningen av operatörsverktyget samt för en ökad förståelse för verksamheten och ämnesområdet. I dagsläget saknas direkt återkoppling, i realtid, för den kontinuerliga utvecklingen av de rörliga kostnaderna eftersom nuvarande uppföljning är baserad på månadsrapporter. Operatörsverktyget som arbetet utmynnade i kommer med hög sannolikhet vara av betydelse för utvecklingen av verksamheten på företaget. Operatörsverktyget kommer även att understödja både styrningen och kontrollen av processens rörliga kostnader. Förhoppningen är att verktyget skall fungera som ett hjälpmedel i arbetet med att optimera arbetet och processen. Några av de fördelar som operatörsverktyget förväntas ge är bland annat att operativa prestationer omedelbart kan kopplas till företagets resultat, ett snabbt synliggörande av exempelvis resultat vilket öppnar för faktabaserad beslutsstrategi samt att viktig information inte behöver gå förlorad. Operatörsverktyget kan framöver anpassas och utnyttjas på fler av verksamhetens pappersmaskiner.

An Analysis of the Telecommunications Business in China by Linear Regression

In this paper, we study the influence of the National Telecom Business Volume by the data in 2008 that have been published in China Statistical Yearbook of Statistics. We illustrate the procedure of modeling “National Telecom Business Volume” on the following eight variables, GDP, Consumption Levels, Retail Sales of Social Consumer Goods Total Renovation Investment, the Local Telephone Exchange Capacity, Mobile Telephone Exchange Capacity, Mobile Phone End Users, and the Local Telephone End Users. The testing of heteroscedasticity and multicollinearity for model evaluation is included. We also consider AIC and BIC criterion to select independent variables, and conclude the result of the factors which are the optimal regression model for the amount of telecommunications business and the relation between independent variables and dependent variable. Based on the final results, we propose several recommendations about how to improve telecommunication services and promote the economic development.

Spanning Tree Approach On The Snow Cleaning Problem

Snow cleaning is one of the important tasks in the winter time in Sweden. Every year government spends huge amount money for snow cleaning purpose. In this thesis we generate a shortest road network of the city and put the depots in different place of the city for snow cleaning. We generate shortest road network using minimum spanning tree algorithm and find the depots position using greedy heuristic. When snow is falling, vehicles start work from the depots and clean the snow all the road network of the city. We generate two types of model. Models are economic model and efficient model. Economic model provide good economical solution of the problem and it use less number of vehicles. Efficient model generate good efficient solution and it take less amount of time to clean the entire road network.

Developing a Communication link between Agents and cross Platform IDE

The main objective of this thesis work is to develop communication link between Runrev Revolution (IDE) and JADE (Multi-Agent System) through Socket programming using TCP/IP layer. These two independent platforms are connected using socket programming technique. Socket programming is considered to be newly emerging technology among these two platforms, the work done in this thesis work is considered to be a prototype.A Graphical simulation model is developed by salixphere (Company in Hedemora) to simulate logistic problems using Runrev Revolution (IDE). The simulation software/program is called “BIOSIM”. The logistic problems are complex, and conventional optimization techniques are unlikely very successful. “BIOSIM” can demonstrate the graphical representation of logistic problems depending upon the problem domains. As this simulation model is developed in revolution programming language (Transcript) which is dynamically typed and English-like language, it is quite slow compared to other high level programming languages. The object of this thesis work is to add intelligent behaviour in graphical objects and develop communication link between Runrev revolution (IDE) and JADE (Multi-Agent System) using TCP/IP layers.The test shows the intelligent behaviour in the graphical objects and successful communication between Runrev Revolution (IDE) and JADE (Multi-Agent System).

Konfigurationshanteringsverktyg (CM-verktyg) och CM-kriterier, dess tillämpning för presentation av migreringsdata

The purpose of this thesis is to present and describe which criteria, according to the systemfamily Configuration Management, should be met when developing a CM-tool to handlemigration data.ACT is a tool developed by Microsoft to gather information about, analyze, test and mitigateapplications in a network when migrating the IT-infrastructure of an organization to a newoperating system. The organization that is being studied wants to present the data about theanalyzed applications in such a way, that a customer can choose what to mitigate and migrate.The goal is therefore to develop a prototype (CM-tool) that will present this data.The study has shown that ACT lacks certain requirements stated by the organization when itcomes to presentation. But when it comes to the rest of the functions, ACT performs as expected.The investigation resulted in specifications and technical solution for the new CM-tool. CMcriteriafor migration data was put forth and parts of the prototype were also developed.

Praktiska effekter av begreppsförvirring för en databas konceptuella design : En fallstudie om databas- och begreppsmodellering

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. The unclear concepts have remained in thedatabase and in the company organization and caused a general confusion of concepts. The splitdatabase architecture itself has evolved into a bottleneck and is the cause of many problemsduring the development of System Y.Company X investigates the possibility of integrating the historical database with the productiondatabase. The goal of our thesis is to conduct a consequence analysis of such integration andwhat the effects would be on System Y, and to create a new design for the integrated database.We will also examine and describe the practical effects of confusion of concepts for a databaseconceptual design.To achieve the goal of the thesis, five different method steps have been performed: a preliminarystudy of the organization, a change analysis, a consequence analysis and an investigation of theconceptual design of the database. These method steps have helped identify changes necessaryfor the organization, a new design proposal for an integrated database, the impact of theproposed design and a number of effects of confusion for the database.

The Choice of STIGA Table Tennis Blades : Evidence from China

The purpose of this paper is to investigate how individuals with different characteristics make their choice-decisions when consuming STIGA table tennis blades, which are combinations of various attributes, such as price, control, attack, etc. It is expected that the general trend of choice behavior on this special commodity can be, at least to some extent, revealed. Data were collected using questionnaires sent to registered members of a table tennis club in China. The questionnaires included information and questions about individuals’ monthly income levels, ages, technique styles, etc. A multinomial logit model was then applied to analyze factors determining Chinese consumers’ choice behavior on STIGA table tennis blades. The results indicated that the main element influencing Chinese consumers’ choice of STIGA ping-pong blades was the technique style and other variables did not seem to influence the choice of table tennis blades. These results might be explained by the limited sample size as well as unmeasured and immeasurable factors. Thus, a more extensive research is needed to be conducted in the future.

Visuell utvärdering av frekvensmodulerat raster på obestruket papper.

This thesis investigated if a combination of increased under colour removal (decreasing the total ink limit), normal andincreased density and modern FM-screening could be used to provide a visually better print on uncoated and coated paperin comparison with AM-screening using the same conditions.Two different test groups (one with graphic background, the other with no graphic background) were asked to a visuallyassess the quality of the prints presented in a pair comparison using a reference image.The results show that the FM-screening did not obtain any significant visual difference in comparison with AM-screening,regardless of paper types and density levels. In general however, prints on coated paper were graded higher.

Ledning och övriga anställdas upplevelser av attraktivitet på arbetsplatsen "Mora of Sweden".

Ledning och övriga anställdas upplevelser av attraktivitet på arbetsplatsen “Mora of Sweden” looks at how management and employees at the Swedish manufacturing company ”Mora of Sweden” perceive an ideal attractive company and what factors that determine one, as well as how these two groups perceive the situation at their own company. The main purpose of the essay is to compare the management’s point of view with that of the rest of the employee respondents’ perspective. While doing so the author concludes that there are several factors such as how the employees feel about their physical working environment as well as their salary, of which the management lacks understanding or perceive differently and that there needs to be more of an open dialogue between the management and the employees.

ANFIS BASED MODELS FOR ACCESSING QUALITY OF WIKIPEDIA ARTICLES

Wikipedia is a free, web-based, collaborative, multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Due to the free nature of Wikipedia and allowing open access to everyone to edit articles the quality of articles may be affected. As all people don’t have equal level of knowledge and also different people have different opinions about a topic so there may be difference between the contributions made by different authors. To overcome this situation it is very important to classify the articles so that the articles of good quality can be separated from the poor quality articles and should be removed from the database. The aim of this study is to classify the articles of Wikipedia into two classes class 0 (poor quality) and class 1(good quality) using the Adaptive Neuro Fuzzy Inference System (ANFIS) and data mining techniques. Two ANFIS are built using the Fuzzy Logic Toolbox [1] available in Matlab. The first ANFIS is based on the rules obtained from J48 classifier in WEKA while the other one was built by using the expert’s knowledge. The data used for this research work contains 226 article’s records taken from the German version of Wikipedia. The dataset consists of 19 inputs and one output. The data was preprocessed to remove any similar attributes. The input variables are related to the editors, contributors, length of articles and the lifecycle of articles. In the end analysis of different methods implemented in this research is made to analyze the performance of each classification method used.

Universal Experimental Measurement System «Sun-Walker» : Automotive measurement system for the evaluation of the solar irradiation distribution for the tests of the solar concentrated systems.

This Thesis project is a part of the research conducted in Solar industry. ABSOLICON Solar Concentrator AB has invented and started production of the prospective solar concentrated system Absolicon X10. The aims of this Thesis project are designing, assembling, calibrating and putting in operation the automatic measurement system intended to evaluate distribution of density of solar radiation in the focal line of the concentrated parabolic reflectors and to measure radiation from the artificial source of light being a calibration-testing tool.On the basis of the requirements of the company’s administration and needs of designing the concentrated reflectors the operation conditions for the Sun-Walker were formulated. As the first step, the complex design of the whole system was made and division on the parts was specified. After the preliminary conducted simulation of the functions and operation conditions of the all parts were formulated.As the next steps, the detailed design of all the parts was made. Most components were ordered from respective companies. Some of the mechanical components were made in the workshop of the company. All parts of the Sun-Walker were assembled and tested. The software part, which controls the Sun-Walker work and conducts measurements of solar irradiation, was created on the LabVIEW basis. To tune and test the software part, the special simulator was designed and assembled.When all parts were assembled in the complete system, the Sun-Walker was tested, calibrated and tuned.

Perspektiv på HR-arbete vid nedskärningar : - en studie om effekter och handlingar, utifrån tre perspektiv, för den fortsatta överlevnaden

Studien ämnar till att skapa en profil för tre olika empirinära perspektiv, vilka alla spelar en roll före, under och efter en nedskärningsprocess. Dessa tre perspektiv är: ledningsperspektivet, perspektivet för kvarvarande anställda och uppsagda arbetare. Författaren lägger tyngd på den tidigare vetenskapliga forskningen som får agera likt en mall för hur en optimal hantering ska ske under en nedskärningsprocess. Syftet med studien är att detektera bristande överrensstämmelser mellan perspektiven som förhindrar att hanteringen blir optimal för alla parter, samt kunna se om teorin används i det praktiska utövandet.Ledarskapsperspektivet är representerat i två underkategorier: sekundärintervjuer och expertintervjuer. I sekundärintervjuerna så presenteras svar från auktoriteter inom området som förmedlar den erfarenhetsbaserade kunskapen; medan i expertintervjuerna presenteras svar från fyra olika, representerade, företag inom olika branscher i Borlänge. Perspektivet för kvarvarande anställda representeras av en enkätundersökning och en djupare intervju med en kvarvarande anställd. Det tredje empirinära perspektivet, för uppsagda arbetare, representeras av en enkätundersökning och en djupare intervju med en uppsagd arbetare.I resultatet så visar det sig att författaren har kunnat detektera bristande överrensstämmelser på flera punkter, främst inom den uppfattade kommunikationen, mellan perspektiven. Detta tolkas som att de framlagda teorierna inte följs av praktiken och därför råder det ingen optimal situation för något av de representerade perspektiven.

IT-system och organisationsutveckling

This report describes work on the thesis “IT systems and organizational development”. The work is carried out on Stocksbro Energi AB, during spring 2009. The company wanted better flow in their production but also review if the inventory management function located in Visma SPCS Administration 2000, could be used in the organization. Under the first part of this report the system were tested to ensure if the system would work together with the organization. After testing the desired features they were evaluated along with two of the users to the system at the company. The wanted functions could not be obtained whenthe Admin 2000 is an economic system and are not made for the producing companies. Thereafter the theoretical possibility was examined of introducing a more advanced system to get the desired functionality to work together with the organization. To introduce a more advanced system will require major changes of the organization, before, during and after the introduction. It is therefore important how the management implements a possibility of a new system. It’s important to make the staff join in this implementation but also get as much as possible out of the system.To conclude the thesis a goal and problem analysis but also a solution proposal was made with the help of the FA/SIMM method. Also some suggestions are mentioned how the company could proceed in the implementation of the proposals for a solution.

Systemutveckling med ett eTjänsteperspektiv : en eTjänstemetod för utveckling av kundfokuserade eTjänster

Göran Hultgren är författaren till eTjänster som social interaktion via användning av IT-system (2007), vilken är en praktisk teori som syftar till att vara till hjälp vid analyser av eTjänster. Eftersom Hultgrens avhandling går ut på att analysera befintliga eTjänster saknas det riktlinjer för hur teorin kan tillämpas praktiskt under utvecklingen av nya eTjänster. Syftet med dennauppsats är att ta fram en systemutvecklingsmetod utifrån den praktiska eTjänsteteorin.eTjänstemetoden som vi tagit fram är baserad på en litteraturstudie av Hultgrens avhandling.Metoden består av ett antal steg som man kan följa vid utvecklingen av en eTjänsten. Den skall inte ses som en fullständig systemutvecklingsmetod utan skall fungera snarare som enkompletteringsmetod som syftar till att ett eTjänsteperspektiv behålls under hela utvecklingen.Vi hade som uppdrag av SkiBar System AB att utveckla ett community där vi kunde testa våreTjänstemetod under utvecklingen. Metoden visade sig vara ett bra sätt att behålla ett eTjänsteperspektiv,det vill säga att alla communitys tjänster syftade till att höja värdet för kunden.
