Problem Analysis,se the findings for planning and control. To measure efficiency criteria which correctly and truly reflect the priorities and preferences are needed. As far as possible, such criteria should be quantitative rather than qualitative and for that benefits and sacrifices, outputs and inputs need to be m

Applications and Quantifications,e or cost identified. The conceptual models were formalized in mathematical equations with the purpose of generalizing the problem and of allowing abstract study of reality under a wide range of work conditions. The ultimate goal is to find optimal solutions with regard to input/output relationships

Energy Analysis,e energy in the form of biomass. A considerable part of the biomass of the tree crop is being used to satisfy human needs. The second aspect on energy in forestry is that for the management, harvesting and conversion of the biomass to marketable or useful products energy is used. This input is not i

Problem Identification, and quality — with limited sacrifices, a necessity arises to manipulate the forest resource towards increasing yields through a planned input of human activities. To economize with human activities in forestry is the notion of operational efficiency with which this book is concerned.

Applications and Quantifications,tract study of reality under a wide range of work conditions. The ultimate goal is to find optimal solutions with regard to input/output relationships. The mathematics is by purpose as simple as possible which will enable the student to focus his attention on the problem per se rather than be distracted by complex mathematics.
