Benefit transformation curves are derived from a multiple objective linear programing model. These transformation curves are used to assess the relationship between objectives. The model consists of a weighted objective function which can be parametized. Procedures are suggested to narrow the search for an efficient management strategy on the transformation curve. However, the validity of the transformation curve depends on how non‐commensurables are valued and so different methods of valuation are presented and used. The model is illustrated through application to a policy problem in northern New South Wales, Australia.
