✦ Synopsis

This paper discusses the adaptation of basic knowledge representation constructs to the treatment of imprecise or uncertain information, the modelling of which uses distribution and scalar value respectively. Other representation issues such as the use of variables and the organization of rules in networks are briefly addressed. Then the problems of matching and propagation (in deductive inference and combination mechanisms) are considered in the specific setting of imprecision and uncertainty. Lastly, some questions concerning control strategies involved in such a problem are briefly considered.

When stochastic simulation of inflow turbulence random fields is employed in the analysis or design of wind turbines in normal operating states, it is common to use well-established standard spectral models represented in terms of parameters that are usually treated as fixed or deterministic values.
