The analysis methods described are all applied to real agricultural energy system problems such as biomass energy, energy uses in livestock housing and ethanol production on the farm. The techniques include expert systems, linear programming and simulation. Knowledge-based systems allow expression of the expert's concepts in a language and form that is much more like the expert's personal language. Linear programmimg is used to solve the complex, realistic problem of energy crop analysis. Drying of grain crops is a major energy cost and simulation methods take into account risks of increased field and storage lossses when energy inputs are reduced. This handbook is filled with techniques, programs and data for analysis of various agricultural energy systems. Methods are detailed enough for the expert reader and extensive tables show energy requirements for a large number of industrial processes related to processing agricultural products and converting and utilizing biomass energy.
