Bugs are an unavoidable aspect of mathematical programming (MP) modelling. In this paper we discuss the prevention and diagnosis of bugs in MP models. The topic is rarely addressed in the literature but is crucial to the success of modelling projects, especially for large models. We argue that...

Modelling complex systems such as multiple-use reservoirs can be challenging. A legitimate question for scientists and modellers is how best to model their management under uncertain rainfall. This paper studies whether it is worth using a stochastic model that requires more effort than a much...

This study reports findings from a mail survey of Western Australian broadacre farmers participating in quality assurance (QA) accreditation. A 50 percent response rate generated a sample size of 78 usable replies. The average farm in the survey spent $13,470 gaining QA accreditation, upgrading...

Few studies of farm technical efficiency consider differences in the physical environments of the farms. This study examines rain-fed broadacre agriculture and shows how neglect of rainfall differences between farms affects measures of farm technical efficiency (TE). Applying data envelopment...
