This manual is designed to facilitate the use of DTRAN, a forest management scheduling model designed to consider multiple market locations and associated marketing alternatives. This manual is not intended to teach forest management scheduling, timber supply analysis or forest planning. The authors assume that the users of this program have some expertise in these areas, as well as experience in using personal computers running under the DOS operating system environment. The manual is broken down into several distinct sections that the user may consult as needed. The first section gives a general overview of the importance of transportation considerations in forestry, a brief review of forest management planning methods and a description of the concept of timber supply. The basic solution approach used by DTRAN is also described and compared to the DUALPLAN model for forest management scheduling. The second section provides a more detailed description of important aspects of the problem including the basic method used to describe the transportation network and its impact on timber stand values. The third section describes briefly the linkages with two other modelling systems that have been developed in conjunction with the development of DTRAN. The DTRAN model is very data intensive as all information impacting timber supply model should be incorporated into the model. Sections four through seven are devoted entirely to the definition and structure of the input information. The main input file and an output file for a test case problem are shown in section eight.
