Optimizing life cycle costs for buildings

Coauthor: Alexander Martin


Life cycle oriented optimization of infrastructures is concerned with the automatic planning of buildings, plants etc from the first line of drawing up to the final polishing of the windows. Turning this into a mathematical model results in a very complex problem. There are a vast number of influencing factors, which have to be considered and which have a strong impact on the final solutions. In the case of our application scenario, namely public buildings, this leads to huge mixed-integer linear programs. To develop solution methods for the application we decompose the problem into subproblems, which stay hard to solve individually, too. In the buildings scenario we present the room allocation problem and take a closer look at different aspects like the planning of escape routes which we formulate as a graph theoretical problem and analyze its complexity. Moreover we present a mathematical model and solution methods for the complete room allocation problem.
