A proactive collaboration with customers facilitates serving of their explicit as well as implicit requirements. However, current supply chain organisation and installed information systems have often problems with dynamic interfacing of supply chain actors and with supporting real life interaction principles. Therefore, specifically interaction between supplier's suppliers with customer's customer is hardly to achieve, notably if distributed and asynchronous interaction takes place in between those peers. Therefore, the paper presents a research approach, which tackles this problem scenario by aiming at an intelligent usage of networked devices like e.g. PDAs and mobile phones, combined with the enabling technologies "Radio Frequency Identification" and "Global Navigation Satellite systems". Furthermore, the key technical characteristics of a potential solution environment are presented, outlining the major components with respect to an architectural and security infrastructure as well as software agents and services for supporting decentralised coordination of tasks in supply chains.

The paper presents the theoretical background and realization of a KM system for the technically advanced customer and product support in the Ambient Intelligence (AmI) domain. Current products include more and more elements of AmI. AmI area is still not state-of-the art in market available products, but there is a clear trend towards products which will be fully based or include different forms of AmI. The paper presents a new KM system using CBR to support so-called AmI product extension. The product extension includes customer support in solving different problems related to the AmI products utilisation. The paper specifically explores the challenges due to increased/more complex interaction between the customers and AmI products. The approach for definition of appropriate set of attributes in CBR system to describe different cases and problems with AmI products is elaborated. The objective is to define a system suitable for AmI products provided by SMEs but capable to cope with the complexity imposed by AmI aspects. The KM system developed and the results of initial testing in industrial environment of SMEs are presented.

In a research project that was funded by the German Federal Government Department of Research an advanced robot control method was conceived and realised, in which a dynamic robot model is integrated in the joint control of the robot Reis RV6. By this model-based control method the path deviations are substantially reduced. This leads to a decrease of actuator input values and thus to lower loads at the actuators and to an improved control behaviour of the robot. As a result, both significant improvements in the path accuracy at high path dynamics and substantially reduced loads of motors and gears have been achieved. The new control method gives an important contribution to higher quality and productivity and also to higher service lives in many application cases.

The paper addresses the problem of the practical stabilisation of manipulation robots which are in the contact with a dynamic environment. The model uncertainties represent the crucial problem in the control of robots within such tasks. Therefore, it is of practical interest to require a relaxed stability condition, the so-called practical stability of the system. A new method for analysis of a practical stability of robots is presented following the basic idea of a decomposition/aggregation method for the stability analysis of large-scale systems. The objective of the paper is to establish for the first time less conservative conditions for the practical stability of the robots around the programmed motion and interaction forces with the environment. The approach appears to be particularly suitable for the analysis of the so-called decentralised control laws. The elaborated procedure is demonstrated on an example.
