Abstract: This paper describes a Regional Resource Allocation Model, known as RegRAM-I, that has been used by Tasman Forestry Ltd, since 1991 as the company's major resources planning tool. RegRAM-1 allows the user to interactively describe the objects to be modelled, (forests, processes, external suppliers, markets), transport costs between various locations, and how time is to be treated, on separate independent spreadsheets. The system uses both optimisation and simulation techniques, and can generate: individual stand models, single time period re source allocation models, single forest 'on-truck' models, multiple forest 'delivered to mill gate' models, multi-location integrated forestry and processing models - all without the need for separate mathematical formulations.
