摘要

基于可拓理论提出了一种农业机械安全风险评价方法。通过研究构建了物元模型,运用在关联函数计算基础上的优度评价方法计算优度。比较每个评价等级的优度值确定待评案例安全风险等级。基于可拓方法的评价模型不仅能够反映单项评价指标对安全的影响,而且能够全面反映待评案例的整体属性。实例证明,该评价方法科学、清晰、合理,具有较好的可行性和实用性。
        A mechanical safety and risk evaluation based on extension method was proposed. The matter element models were constructed, and the goodness of mechanical design scheme was computed by using goodness evaluation method based on correlation function calculation. Then the level of safety and risk was determined by comparing the goodness value of each evaluation grade. The evaluation model based on extension method not only reflected the impact of the safety of the individual evaluation, but also reflected the overall attributes. Finally, the practical application showed that the decision-making methods was clear, reasonable and had good feasibility and practicality.
