  text: Self-optimizing systems are able to adapt their behavior autonomously according
    to their current self-determined objectives. Unforeseen influences could lead
    to dependability-critical behavior of the system. Methods are required which secure
    self-optimizing systems during operation. These methods to increase the dependability
    of the system should already be taken into consideration in the design process.
    This paper presents a guideline for the dependability-oriented design of self-optimizing
    systems, which integrates established classical methods like failure mode and
    effects analysis as well as methods based on self-optimization. On the one hand
    self-optimization is used to increase the dependability of the system by integrating
    objectives like safety, availability, and reliability to the objectives of the
    system. On the other hand methods are required to ensure the self-optimization
    itself. As basis for this guideline serves the principle solution of the system.
    The six phases of the guideline extend the design process and lead to an enhanced
    principle solution. Additionally, the guideline illustrates phases to implement
    and validate the self-optimizing system. The proposed guideline is applied to
    an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
    function modules.

  text: Recent advances in information processing enable new kinds of technical systems,
    called self-optimizing systems. These systems are able to adapt their objectives
    and their behavior according to the current situation and influences autonomously.
    This behavior adaptation is non-deterministic and hence self-optimization is a
    risk to the system, e.g. if the result of the self-optimization process does not
    match the suddenly changed situation. In contrary, self-optimization could be
    used to increase the dependability by pursuing objectives like reliability and
    availability. In our preceding publications we introduced the so called multi-level
    dependability concept to cope with this new kind of systems (cf. [6]). This concept
    comprises the monitoring of the system behavior, the classification of the current
    situation, and the selection of the appropriate measure, if reliability limits
    are exceeded. In this paper we present for the first time experimental results.
    The dependability concept is implemented in the self-optimizing active guidance
    system of a railway vehicle. The test drives illustrate clearly that the proposed
    concept is able to cope with, e.g., sensor failures, and is able to increase the
    reliability and availability of the active guidance module.
