The farm planning problem is a critical aspect in the design of decision support systems (DSS) for complex farm advising. Difficulty for decision making in modern agribusiness has increased significantly, since it involves a large number of strongly interrelated factors. The book begins with an overview of the evaluation-based model use to support various decisions in agribusiness. It follows with a brief illustration of a research object hops - as an important brewing raw material. Furthermore, the three chapters demonstrate various examples of modeling of decision support systems - related to a quality management of hops. This book complements the authors’ previous publications as an outcome of their research and advisory activities in a hop industry - predominantly within initiatives of the International Hop Growers’ Convention (www.ihgc.org).
