Abstract

In the early 1980s, the Department of Agriculture developed a mixed integer whole-farm mathematical programming model of the dryland farming system in the eastern wheatbelt of Western Australia (Morrison et al. 1986). The model named MIDAS (Model of an Integrated Dryland Agricultural System) was constructed, tested and scrutinised by a multi-disciplinary team of researchers, advisers, farm management consultants and farmers (Kingwell 1987a). The model described in some detail the biology and finances of the dryland farming system in an average season and calculated profit-maximising farm plans.

MIDAS remains an often used tool in research and extension, being applied to many issues and problems (e.g. Kingwell and Pannell 1987, Morrison and Young 1991).

This publication describes a model based on MIDAS, but considerably more complex, that accounts for season and price uncertainty and farmers' abilities to respond tactically to seasonal events. It is called Model of an Uncertain Dryland Agricultural System (MUDAS).
