The main goal of this project is to evaluate and demonstrate the feasibility of a new framework to be used to design and control external simulators at SAAB AB. The project explore the possibility of developing a web-based framework in a secure environment, based on Docker technology and modern application frameworks. In order to reach the main goal, a qualitative interview is conducted, which is used to design the new framework. An evaluation of the feasibility of the new framework is performed. For that a proof of concept has been developed, together with a measure of performance and the return of investment of the new framework. With the proof of concept together with the performance evaluation, it is proved that a new web-based framework is suitable to design and control external simulators. Furthermore, the return of investment is estimated to be 76.73% per year, which suggests that the benefits would succeed the investment cost of the new framework, if used for more than 16 months.
