The decision model is the core of each decision-making process, as it lists all factors which have an influence on the decision. Our decision model considers the Swiss legislation and consists of 38 attributes that are grouped into 3 categories. Furthermore, each factor is assigned a main objective that is fulfilled the more the according factor is avoided from building a power line on its top.
