摘要： 针对传统用户需求分析方法存在的主观性强、需求描述难以量化等问题，提出了基于运行数据的性能需求推断方法.首先采用分布拟合法对运行性能数据进行拟合和估计.在此基础上，确定用户需求区间，并以累计概率分布的逼近函数——Sigmoid-like来构建用户需求满足度函数.基于该函数提出了用户性能需求推断公式，并将推断结果与用户感知结果进行对比分析.最后，以手机电池容量性能需求为例，利用自主研发的Smart Monitor系统采集到的手机日耗电量、电池剩余电量、充电次数等数据，对志愿者的手机电池日耗电量进行2次推断实验.2次实验的结果误差均小于 5.00%，验证了所提出的理论方法具有可靠性.

Abstract: Customer requirement analysis is the premise of product design. The traditional methods for requirement analysis include market research methods and online comment analysis. These methods are subjective and difficult to quantify the description of the requirements. Therefore, a method based on operating data is proposed to identify the customer performance requirements. Firstly, the distribution fitting method is used to fit the performance distribution. Based on this, the user required performance interval is determined, and the customer satisfaction function is constructed with the approximation of Sigmoid-like function of the cumulative probability distribution. Based on the function, for a given certain satisfaction degree, the customer required performance can be obtained and also used for comparison with user’s perception. At the end of this paper, two experiments are conducted for analyzing the volunteers’ performance requirement on their mobile battery module through the data collected by the Smart Monitor system we developed, including daily cumulative power consumption, residual capacity, number of charge cycles. The errors between two experimental results are less than 5.00%, which verifies the theoretical method we proposed.

Key words: performance requirement analysis, perception analysis, operating data, data driven, customer satisfaction function
