Idag byter många företag ut sina gamla informationssystem mot nya, standardiserade affärssystem. Detta görs för att man ser stora framgångs- och konkurrensfaktorer i att ha ett standardiserat system, att anpassa ett affärssystem mot verksamheten blir dessutom väldigt kostsamt. På Saab Aerosystems införde man under 2006 just ett standardiserat affärssystem, IFS Applications 2004, där man tidigare hade använt sig utav 59 olika system.Syftet med denna uppsats är att undersöka vilka möjligheter och utmaningar man såg på Saab Aerosystems i och med införandet av det nya affärssystemet. Det utfördes en fallstudie där det samlades in empiri från ett antal kvalitativa intervjuer för att kunna jämföras mot den teoretiska referensram och på så sett kunna besvara frågeställningarna; vilka möjligheter uppstod i samband med införandet av det nya affärssystemet? Hur tog dessa tillvara på? Vilka utmaningar uppstod i samband med införandet av det nya affärssystemet? Hur hanterades dessa? Många av utmaningarna respektive möjligheterna kan ses som nära relaterade, i denna studie presenterar vi hur olika aktörer inom verksamheten upplevt dessa, samt hur de relaterar till existerande teori på området.Resultat visar att följande kategorier: förändring, anpassning av och gentemot affärssystemet, strategi, utbildning och hjälpresurser utgjorde stora utmaningar.

Detta examensarbete har förlagt sig på Saab Aeronautics i Tannerfors, Linköping. Saab Aeronautics utvecklar och bygger Jas Gripen. Saab Aeronautics i Linköping utvecklar simulatorer som används för att testa olika versioner av mjukvara som används i JAS Gripen plan. Dessa simulatorer används inte bara av utvecklare i testsyften utan även av piloter som övar inför uppdrag och för att ge feedback till utvecklarna om mjukvarorna. Vi utförde examensarbetet på simulatorcentralen på området.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

This reports goal is the give BSR AB more information that's useful towards their customers in marketing of their products.It involves tests of different air filters designed for cars and 3D-modelling of Opti-Flow systems. The three models thats being tested is SAAB (93SS), VAG (1.8T) and Volvo (S60). To every brand there are three different models. A orginal- , sport- and an open cone air filter (Opti-Flow).The results indicate that the open Opti-Flow filter has better performance compared to the other cased filters. The sport filters for SAAB and Volvo has better performance then the original filter.

Målet med examensarbetet har varit att ta fram teoretiskt underlag och en beräkningsmodell. Detta ska beskriva hur kabeltyp, kabellängd, kabelarea samt effektfaktor påverkar spänningsfallet över ett 400 Hz ledningssystem.Mätningar har utförts på två olika kablar som används i det aktuella systemet. En av kablarna var symm­et­riskt uppbyggd med 7 ledare, där respektive fas bestod av två ledare förskjutna 180° från varandra runt nolledaren. För att åstadkomma 115/200V 400 Hz, användes en 90 kVA frekvensomformare. Belastningen som användes var en resistiv, induktiv samt en kapacitiv belastning.

Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

På SAAB Aerostructures i Linköping utvecklas och tillverkas delsystem, så som dörrar och skevroder, till kommersiella flygplan åt framförallt Boeing och Airbus. Inom flygindustrin går utvecklingen mot en större användning av kompositmaterial i denna typ av strukturer. För att befästa sin position på marknaden och bygga kunskap kring konstruktion i och tillverkning av kompositmaterial har SAAB startat ett forskningsprojekt kallat GF Demo. Projektet syftar till att ta fram nästa generations kompositstrukturer för civilflygplan, samt att utveckla effektiva produktionsprocesser för detta. En utmaning med konstruktioner i kompositmaterial är den dyra och komplexa tillverkningsprocessen.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Saab har utvecklat en produkt, Remote Tower, som tillåter flygledningen att fjärrstyra en flygplats, det vill säga att övervaka och kontrollera en flygplats på distans. Ett viktigt verktyg för flygledarna är VCS, Voice Communication System, som är Saabs egna röstkommunikationssystem, där både radio- och telefonkommunikation ingår. VCS används för att kommunicera med piloter och markpersonal på flygplatsen. Målet är att i framtiden kunna fjärrstyra fler flygplatser samtidigt, och då finns ett behov att visualisera de inkommande samtalen från de olika flygplatserna i realtid. Detta för att undvika ett scenario där flygledaren missar ett samtal.
