input uncertainty system data uncertainty Oliver He Jinjing Guo Jie Zheng Uncertainty about the systemdata that ‘drive’ themodel and typically quantify relevant features of the reference system and its behaviour (e.g. land-use maps, data on infrastructure (roads, houses)). Uncertainty about system data is generated by a lack of knowledge of the properties (including both the deterministic and the stochastic properties) of the underlying system and deficiencies in the description of the variability that can be an inherent feature of some of the phenomena under observation. https://www.tandfonline.com/doi/abs/10.1076/iaij.4.1.5.16466 系统数据不确定性
