The analysis of production systems using discrete, event-based simulation is wide spread and generally accepted as a decision support technology. It aims either at the comparison of competitive system designs or the identification of a "best possible" parameter configuration of a simulation model. Here, combinatorial techniques of simulation and(More)
In this paper we show how to manage speech understanding using a control algorithm which enables parallel processing and is based on iterative optimization. The task speciic knowledge is represented by a semantic network consisting of concepts representing objects, and links. An optimal interpretation of a spoken utterance is available if a best scored(More)

In this paper knowledge based image interpretation is formulated and solved as an optimization problem which takes into account the observed image data, the available task speciic knowledge, and the requirements of an application. Knowledge is represented by a semantic network consisting of concepts (nodes) and links (edges). Concepts are further deened by(More)
We use an innovative approach to speech understanding which is based on a fine-grained knowledge representation automatically compiled from a semantic network, and on an iterative control strategy. This approach, besides allowing an efficient exploitation of parallelism, enables the system with anytime capability since after each iteration a (suboptimal)(More)
This paper presents aspects of the integration of the enhanced capabilities of B-ISDN signalling in the field of Distributed Processing Environments for telecommunication networks, developed in the CAMOUFLAGE project. The mechanisms of operational and stream oriented object communication provided by a B-ISDN based DPE are shown. The advantages of this(More)
