In order to effectively design an automated office system, it is necessary to understand the nature of office procedures and interactions. In the design of any office system, characterization and formalization of the information flow through the office are important factors in the attainment of effective system design. A model has been developed by defining office components and their representation in terms of system objects, attributes and relations. The model is based on a set of rules specified in a manner that supports analysis of system completeness and consistency. The model representation has been combined into an office specification system which consists of a specification language and analysis software. Using the system presented, information flow through an office can be characterized and formalized. The system provides the capability of categorizing data into one of a number of data types and of tracking data as it travels through an office. These capabilities provide information necessary to eliminate redundant data, indicate incomplete data, and specify useless data. Through the use of analyzer reports and analysis software, system completeness and consistency are determined.

With the rapid advance of information technologies, human beings increasingly rely on computers to accumulate, process, and make use of data. Knowledge discovery techniques have been proposed to automatically search large volumes of data for patterns.Group Support Systems (GSS) play an important role in streamlining group activities and improving group outcomes. Various attempts have been made to help automate several tasks in group activities under GSS environment. One of the approaches is to apply automatic approach to idea organization task in GSS.This research designed and tested an SVD-enabled system to automate the idea organization task in GSS. Specifically, this research was conducted to examine how the idea organization task, typically regarded as the most labor-intensive and cognitively demanding in group problems solving, can be automated using a system enabled by singular value decomposition techniques. For the purpose of evaluation, we compared the performance of our automated approach using SVD algorithm against that of human subjects. Two separate experiments were conducted to evaluate the performance of the automatic approach on two essential components of an idea organization; namely, generation of topic categories and placement of relevant comments into their respective categories.The general conclusion that can be made from this research is that idea organization in group problem solving can be facilitated both efficiently and effectively with the SVD-enabled system that can automatically generate topic categories and place relevant comments into their respective topic categories. Therefore, our automatic approach may provide a useful and promising tool for the idea organization task in GSS.

THIS PAPER IS BASED on thesis work done at Volvo CE Component Division in Eskilstuna, from April to October 2007. The thesis work considered industrial robots within lean production. The purpose was to come up with guidelines on how to work with industrial robots and design productions cells in a lean environment. The authors have used various techniques e.g. literature study, study visit and interviews to reach their result. First the authors tried to make a picture of and define lean automation and then they wanted to compare that picture with the present state of the factory. The purpose was to limit the thesis work to the part of automation that is built by industrial robots and therefore only this type of automation is considered in the current state analysis. The authors consider that a holistic view and a stable foundation are the most important things to start to work with lean automation. The result that is presented in this thesis is most of the times far from specific for the design of the individual cells since the authors felt it more important to focus on building the right environment for lean automation. The easiest and quickest way to summarize the work is the guidelines that are based on the current state analysis made at CE Component Division and the authors’ definition of lean automation. The purpose of the guidelines are to give Component a picture of how to work to create clearer directives when, where and how much the company wishes to implement automation. At the same time they are also meant to help build a structure for work with maintenance, internal transports, packaging etc. The paper also presents a way to work as well as a suggestion on how to work with building an individual cell could be conducted. / DEN HÄR RAPPORTEN BYGGER på ett examensarbete som utfördes på Volvo CE Component Division i Eskilstuna från april till oktober 2007. Examensarbetet behandlade området industrirobotar i ett lean produktionssystem och hade som syfte att komma med riktlinjer på hur arbetet med industrirobotar bör bedrivas och robotceller designas i en lean produktionsmiljö. Författarna har använt sig av ett antal olika sätt, bl.a. litteraturstudier, studiebesök och intervjuer för att komma fram till sitt resultat. Först försökte författarna göra sig en bild av och definiera lean automation för att sedan jämföra den bilden med situationen i fabriken. Utgångspunkten var att begränsa arbetet till den del av automationen som är uppbyggd med industrirobotar och i nulägesanalysen kartlades därför endast de celler som innehåller industrirobotar. Författarna anser att för att arbeta med lean automation är helheten och grunden det viktigaste. Det resultat som presenteras i den här rapporten koncentrerades därför kring att skapa förutsättningarna för lean automation. Arbetet kan enklast, snabbast sammanfattas i de riktlinjerna som togs fram utifrån nulägesanalysen och definitionen av lean automation. Riktlinjerna är tänkta att ge Component en bild på hur de bör arbeta för att skapa klarare direktiv när, var och hur mycket företaget önskar att automatisera. Samtidigt som de även är tänkta att bygga upp en struktur för arbete med underhåll, interna transporter, emballage etc. Rapporten presenterar även ett tänkt arbetssätt samt förslag på hur arbetet med att utforma den enskilda cellen bör bedrivas.
