The Forest Planning Model(FORPLAN) is a conceptually complex model which has been designated as the "primary analysis tool for forest planning" for all American National Forests. This paper defines eight FORPLAN components and shows the three model design frameworks that can be represented in FORPLAN version 1 and version 2.

The recent trend in multiple-use land management planning is using Model I and Model II formulations designed for timber activity scheduling problems. Numerous models hate been developed, with MUSYC(Johnson and Jones, 1979) being the first to incorporate both model structures. Currently the most popular computer program using both Model I and Model II is FORPLAN(Johnson and others, 1986). A Model I formulation requires fewer rows and provides more direct information on what happens to an acre from rotation to rotation. In some problems, Model II provides a much more compact problem matrix with much fewer columns and only a moderate increase in row number. In this paper we examined and evaluated their usefulness in comprehensive multiresource forest management planning.
