An agroecosystem model was constructed comprising four components and their interactions: a stochastic weather generator, a deterministic plant submodel, a stochastic insect submodel, and a heuristic submodel of management decisions represented by a rulebased expert system. Stochastic economic relations were included to transform model output into profit. The model is driven by a random weather generator. The goal is to compare three management strategies, representing an extension specialist, an extension publication and a static economic threshold. Multiple simulations provide distributions of profit under each strategy over a wide range of input conditions. These distributions are compared with stochastic dominance.
