Radio transmission may be a good alternative to the wire based communication for a lot of applications in building automation (Rauchhaupt and Hähniche, 1999). The advantage is an easy, fast and low cost installation scenario. Nevertheless, the radio specifics require a very specialized protocol stack that affects the whole system architecture. Starting from… (More)
We propose a new niching method for Evolutionary Algorithms which is able to identify and track global and local optima in a multimodal search space. To prevent the loss of diversity we replace the global selection pressure within a single population by local selection of a multi-population strategy. The sub-populations representing species specialized on… (More)
We propose the Clustering Based Niching (CBN) method for Evolutionary Algorithms (EA) to identify multiple global and local optima in a multimodal search space. The basic idea is to apply the biological concept of species in separate ecological niches to EA to preserve diversity. To model species we use a multi-population approach, one population for each… (More)
In several applications for automation, radio transmission could be a good alternative to wired field busses . The advantages are an easy, fast and low cost installation scenario in common with the possibility of flexible device placing. But, the specifics of radio require a very specialized protocol stack which effects the whole system architecture.… (More)
Standards are necessary for the successful interaction of field bus nodes. Because of the wide range of field bus applications, the Application Layer are very difficult to define. For the Local Operation Network (LON) detailed device specifications are already established by the LONMark standardisation organisation. This specifications focus on single… (More)
The following tool helps the troubleshooters in factories. It records time-dependent operations and makes these visibly. It offers methods to abstraction and helps to find anomalies.
