TREATMENT OF RISK IN A CROP PROTECTION INFORMATION SYSTEM
研究了农场管理信息系统中风险的重要性,发现对于大麦叶锈病的喷洒决策,使用期望货币价值最大化与期望效用最大化标准在多数年份会得出相同建议。
The importance of risk in a farm‐level management information system designed to help farmers make spraying decisions relating to leaf rust of barley is examined. Using utility functions which were elicited for a small number of cereal growers, and probability distributions of yield losses generated using the information system, it was found that strategy assessment using the criterion of maximisation of expected monetary value or the criterion of maximisation of expected utility could be expected to lead to identical recommendations in most years, for a wide range of risk attitudes.
