The decision to prune trees in fast growing timber plantations is mainly based upon the experience of the decision maker, i.e. on mathematically ill structured knowledge. It is shown that this ill structured knowledge can be adequately modelled with fuzzy set-theoretic mathematics. Aggregation of the pruning decision criteria is achieved using fuzzy aggregation operators in analogy to a fuzzy decision support and fuzzy decision aid, respectively, resulting in a plausible ranking of the pruning decision alternatives.
