LeOpIn – Lebenszyklusorientierte Optimierung für eine ressourcen- und energieeffiziente Infrastruktur

Description

The goal of the project LeOpIn is to devise methods for life-cycle oriented planning and evaluation of buildings and related infrastructure. To this end we develop simulation and optimization tools which can cope with this task. A concrete application is the planning of a building and pipes undergoing high pressure scenarios for which a software solution will be prototypically developed. The development of the planning and evaluation procedures demands a tight interaction between mathematical and engineering techniques. We plan to employ methods of numerical simulation and of discrete and nonlinear optimization. The main focus lies on integration of these techniques since only by this the high complexity of the treated problems can be handled appropriately.

Project A

In project A we are dealing with the problem of arranging the rooms in the planning phase of a given construction project of a building. Since the goal is to minimize the total cost arising over the entire life-cycle we add the operation costs (caused by heating, cooling, lighting and air-conditioning) to the construction costs also. The resulting mixed-integer (non-)linear model (MINLP) will describe the arrangement problem and obey to certain building regulations such as escape routes and static.

Project B – Optimal routing of pipes under physical constraints

In project B our task is to find – given a rough admissible outline – an optimal alignment of one or more pipes in a power plant. This is difficult since the problem raises both combinatorial/discrete structures as well as non-linear constraints which come from the underlying physical model.

One of the main goal of the project is to develop a two-level approach that can easily integrate a better physical model from the other projects into a discrete framework.
