We can see one variation in one input or output data may result in variation of two data in classic DEA models. It increases the difficulty of Sensitivity Analysis.
从经典DEA模型可以看出，若是输入或输出中的某个数据发生变化，那么在单纯形表中，变化的数据实际上是两个，这无疑会加大分析难度。
The key to a successful simulation lies in the completion and precision of the input items and data, and in the adjustments and experiments of the inputs, based on sensitivity analysis.
模拟成功的关键在于输入项目和数据的完整性和准确性以及以敏感性分析为基础的输入数据调整试验。
