In this master thesis a flexible manufacturing system for a PTC machine hall has been modelled and simulated using RobCad. This system includes several equipments and machines which have been modelled and arranged to come up with three possible layouts. The machine hall in UW will be moved to a new place in Innovatum (a research area in Trollhättan). The machines were chosen from the existing machine hall according to UW requirements in order not to buy new machines because of economic reasons. The number of cells was also set by UW. The machines and equipments that will be moved are; two CNC machines, three ABB robots, a 4-axis gantry robot which transport the materials between the cells and a conveyor or a flex link which has been proposed in this project for the loading/unloading station use. The purposes of moving the machine hall to Innovatum are: - More people will be able to use the machine hall (i.e. UW, other schools and costumers from other companies for training purposes). - The environment will be more available to do more production operations using the robots and machines. - It will be a good opportunity to develop the programs and software, for that will let UW be able to hire a whole automation package to the costumers. - Students will be nearby to the industries'9 environment and may have more contact with different companies. - Since the new machine hall will attract costumers it will gain incomes to UW. Three layouts have been proposed in this thesis work, and these layouts fulfil all or most of the requirements of the costumers and users.

Syftet med detta arbete är att skapa ett webbaserat bokningssystem åt Gefle Gourmetservice, en expanderande cateringfirma i Gävle. De krav som finns på systemet har, successivt under arbetets gång, tagits fram tillsammans med ägarna till Gefle Gourmetservice. Ungefär varannan vecka har en avstämning tillsammans med dessa ägare genomförts. På dessa avstämningar har funktionerna, allteftersom de har implementerats, demonstrerats. Bokningssystem har skapats med hjälp av Java Enterprise Edition, d.v.s. med hjälp av Servlets, Java Server Pages samt Java Beans. Systemet är uppdelat i två delsystem. Det första delsystemet är ett administrativt system, där personalen på Gefle Gourmetservice exempelvis kan lägga till och ta bort produkter, granska beställningar samt meddela hur mycket de arbetat. Det andra delsystemet är det som kunderna möts av när de ska göra en beställning. En MySQL-databas är kopplad till systemet och det är driftsatt på ett webbhotell. Det lever gott och väl upp till alla de krav som har tagits fram, varför kunden är mycket nöjd med resultatet.

Systems development methods has always been an important part of the systems development process. It affects not only the product, but also the organization itself. Today more and more companies are abandoning the more rigid traditional methods for the more flexible agile ones. A transition like this is bound to affect the product and the organization, but in what ways? Is it a difficult transition to make, and how does it affect social environment and dynamics? Does it change how people communicate information to each other? This study was conducted at a local branch of a larger international IT-company. The company had recently switched from a traditional waterfall method to the agile method Scrum. The study’s aim was to see if and how this transition caused any changes in the way that the company develops their artifacts. A characteristic for Scrum is that people collaborate in small self-organizing teams. How is this affecting the social structures and the relationships between individuals? The study is of qualitative nature, where semi-structured interviews were conducted with people from the different Scrum teams. The study has shown that this kind of transition takes time, but that people are positive towards its benefits. The fact that individuals are no longer isolated with their own task, but are instead working closely together with their team members has led to, perhaps less, but better and more accurate products. To be in a tight team with a common goal has also made people more content with their social exchange and work situation, which positively affects moral. The physical closeness to the team has led to improvements in the communication and collaboration between teammembers. However it has also had the effect that the communication and collaboration with the other teams have deteriorated, due to the teams having differing ways of working, differing norms and differing goals.
