With the advent of the Information and Communication age, every day new services with better quality and higher bandwidth demands are being developed for a plethora of subscribers. To keep up with this, operators are moving away from copper based access network technologies and towards more future proof optical access network technologies. Depending on the area of deployment and demands of subscribers, there is a need to conduct a quick analysis to find the best time and technology for migrations, in order to maximize the benefits to both the subscribers and operator. This thesis proposes: (i) A techno-economic analysis of different kinds of optical access network architectures, modelling costs in each case, (ii) a classification of different kinds of subscribers present in the network along with their behaviour of joining and leaving the network, (iii) a migration model based on a modified adversarial search technique, which takes as input the techno-economic costs and subscriber behaviours and finds the best technology to migrate to, resulting in the maximum accumulated \acfNPV of the project along with the migration path in time and (iv) a sensitivity analysis to show the effect of various input parameters on the output results.     «
