As the amount and complexity of information relating to the development of bioenergy systems increases so does the problem of how to handle the information in a manner which is helpful for decision making. Hypertext-based information systems and decision support systems are being developed to aid deployment of bioenergy systems. These approaches are discussed with reference to a short rotation forestry production information system and decision support systems for harvesting wood for energy from conventional forestry and short, rotation forestry. The development of a model which integrates biomass production, conversion and electricity generation is discussed. problems encountered when combining different models into an integrated model are addressed.
