The aim is to improve dripper emitters design process reducing costs. A knowledge base is presented to gather data on products behaviour in terms of experimental data and simulation results for a set of meaningful test cases. Input design parameters were linked to performance indices on the base of the correlations emerged in the analysis. Specifications for a new product can be used to extract similar cases and to define a possible solution in terms of a combination of them.enCopyright: Cranfield University 2009Virtual PrototypingKnowledge Based EngineeringDesign of ExperimentsDrip emittersConference paper
