First Results of Hybrid Object-Oriented System for the Optimization of the Construction Site Layout: ESBE

ESBE is a hybrid object-oriented system. The objective is the interactive generation of an optimized construction site layout. The task is the locating of the individual construction site facilities. ESBE consists of three major parts: an object-oriented construction site database which contains general and company specific data of the construction site facilities and the building data; a hybrid system with mathematical optimization algorithms and a knowledge based system as well as well-tailored user-interface with a 3D visualization component.

The output of knowledge-based system is a ranking of the suitable areas (rectangles) in order to place the facilities. These areas serve as input to the mathematical algorithms, computing the optimal locations of the facilities inside these restricted areas. Both parts have been programmed with the object oriented programming language Eiffel. The first results of the developed heuristics are very promising.
