Abstract: A method for performing a three-dimensional analysis of an investigated technical system represented by a corresponding fault tree is provided. The method includes linking basic events logically to a top event of the investigated system. The fault tree is a three-dimensional fault tree. Each event of the fault tree is represented by a three-dimensional body having projection surfaces adapted to output analysis data of the respective event to a user.

Abstract: In a factory planning method, provision is made for the models (15a) of the model layout to be placed on a substrate, with the result that the position of the models can be determined using digital image processing after the models have been placed. As a result, the real models (15a) can be used for clear factory planning, in which case collisions (33) on account of an area requirement (15b) resulting from particular specifications to be displayed by the planning program are and an optimized proposal to preferably also be output are provided for. This advantageously makes it possible to combine the intuitive factory planning method using real models with the factory planning method using planning programs, thus enabling interactive working with both planning methods.

Abstract: In a method for factory planning and a model assembly (13) that is used to perform the method, the models (24, 25) of the model assembly are provided with information carriers (26) such as two-dimensional bar codes so that the position thereof can be determined by digital image processing after placement on the underlayment (14). Thus the real models (24, 25) can be used for concrete factory planning by a three-dimensional, real model, wherein it is possible to transfer the data arising in such a way into a planning program by the information carriers. Advantageously, the method of intuitive factory planning by real models and the method of factory planning by planning programs can be combined with each other in this way, wherein an efficient interface between both planning steps is created by the information carriers, wherein the interface enables in particular also interactive work with both planning methods.
