Strategies for Mastering Uncertainty

Abstract

This chapter describes three general strategies to master uncertainty in technical systems: robustness, flexibility and resilience. It builds on the previous chapters about methods to analyse and identify uncertainty and may rely on the availability of technologies for particular systems, such as active components. Robustness aims for the design of technical systems that are insensitive to anticipated uncertainties. Flexibility increases the ability of a system to work under different situations. Resilience extends this characteristic by requiring a given minimal functional performance, even after disturbances or failure of system components, and it may incorporate recovery. The three strategies are described and discussed in turn. Moreover, they are demonstrated on specific technical systems.

A Review on Sensor‐Integrating Machine Elements

“…[63] For the realization of robustness in technical systems, approaches and strategies can be found in literature, which are mainly oriented toward the cause-effect relationship between disturbance factors and system behavior. [64] The development of robust measurement procedures, in particular of the devices of measurement used therein, such as SiME and the associated measurement signal processing, represents a subject of current research. [65] Based on the definition of robustness given above, disturbance factors can be differentiated into three categories according to Taguchi et al [63] Disturbances due to external causes (e.g., temperature, vibration), disturbances due to internal causes (e.g., wear, deterioration), and disturbances due to manufacturing or assembly tolerances.…”
