决策树方法是近代由图论中发展的一种定量决策方法,它能使复杂的决策过程变得简明直观。本文利用1994年福建省现场调查所得十种常用疟防措施的单位成本,与不同条件下疟防措施实施成功或失败状态下的损益值,试建立福建省特定条件下的疟防决策树。 材料与方法 一、不同措施的单位成本 本文所涉及的成本皆为可变成本。表1中成本值来自现场调查结果。措施成本单位(元/千人口/年)。
The decision tree approach is a quantitative decision method developed in graph theory in modern times, which makes the complicated decision making process concise and intuitive. Based on the unit cost of ten common malaria prevention measures collected in the field investigation in Fujian Province in 1994 and the profit and loss value under the successful or unsuccessful malaria prevention measures under different conditions, this paper tries to establish the malaria prevention decision tree under the specific conditions in Fujian Province. Materials and methods First, the unit cost of different measures The costs involved in this article are variable costs. The cost in Table 1 comes from the field survey results. Measures cost unit (yuan / person population / year).
