The manufacturing resource and manufacturing task information model were constructed and their performance parameters were described based on their uncertainties.The transferring rules from parameter information to interval were discussed.A new optimized searching method

for manufacturing resources was provided using interval analysis.The method was verified to be valid by an instance.

针对网络环境中制造资源和任务信息的不确定性,构建了资源和任务的信息模型,并对其能力参数进行了形式化描述。针对不确定性能力参数,探讨了制造资源参数区间的转化规则。利用区间距离的概念,提出一种在网络环境中进行制造资源优化检索的新方法,并通过实例验证了该方法的有效性。
