目的 物联网技术与数字化技术的发展催生了对电力应急救援设施管控的数字化改造需求。在这类功能较明确的既定目标产品开发中，更需要降低对子功能评价的主观偏差，理性科学地对各项子功能的重要性程度进行合理评价，并最终指导研发投入。方法 以电力应急救援物资数字化入网改造为实践对象，构建UXM-FAST-AHP分析模型，运用“原始+预想”用户旅程比对图，分析构筑理想的使用场景，通过功能分析技术搭建目标功能架构，在子功能集束的基础上，利用成对比较矩阵和层次分析法，降低主观评价偏差，分析各子功能的重要性程度，继而指导设计与研发投入。结论 UXM-FAST-AHP分析模型在既定目标产品的研发过程中也能实现清晰可靠的逻辑分析，有效地帮助既定目标产品开发过程中设计重点的梳理与评估。

The development of Internet of things technology and digital technology has spawned the demand for digital transformation of electric power emergency rescue facility management and control. In the development of such targeted products with clear functions, it is more necessary to reduce the subjective deviation of sub-function evaluation, rationally and scientifically evaluate the importance of each sub-function, and finally guide the R & D investment. With the digital network access transformation of electric power emergency rescue facilities as the practice object, the UXM-FAST-AHP analysis model was built. The ideal use scenario was analyzed and built with the "original + expected" user journey comparison diagram. The target function structure was built through the function analysis technology. And the subjective evaluation deviation was reduced through the pairwise comparison matrix and analytic hierarchy process based on sub-function clustering. The importance of each sub-function was analyzed, and then guided to design and investment. The UXM-FAST-AHP analysis model can also realize clear and reliable logical analysis in the R & D process of the established target products, and effectively help sort out and evaluate the design focus in development of the established target products.
