提出了使用DEA和模拟在指导运营单位提高绩效方面相互支持的潜力。建议分三个阶段进行分析。第一阶段是获取数据进行DEA分析。这可以来自历史数据、模拟数据或两者的组合。第二阶段涉及DEA分析，确定基准经营单位。在第三阶段，现在可以使用模拟来为操作单元提供实际指导，以提高性能。这可以通过使用模拟模型对基准机组进行敏感性分析来实现，以直接支持待测试的操作实践中任何变化的可行性和效率。或者，模拟可以用作一种机制，通过建立较弱单元的模拟模型来将基准单元的实践传递给基准单元的过程设计。然后，该模型可以比较当前工艺设计和基准工艺设计的性能。以这种方式量化改进为任何流程变革举措提供了一个有用的驱动力，这是使较弱单位的绩效达到同类最佳水平所必需的。
The potential for the use of DEA and simulation in a mutually supporting role in guiding operating units to improved performance is presented. An analysis following a three-stage process is suggested. Stage one involves obtaining the data for the DEA analysis. This can be sourced from historical data, simulated data or a combination of the two. Stage two involves the DEA analysis that identifies benchmark operating units. In the third stage simulation can now be used in order to offer practical guidance to operating units towards improved performance. This can be achieved by the use of sensitivity analysis of the benchmark unit using a simulation model to offer direct support as to the feasibility and efficiency of any variations in operating practices to be tested. Alternatively, the simulation can be used as a mechanism to transmit the practices of the benchmark unit to weaker performing units by building a simulation model of the weaker unit to the process design of the benchmark unit. The model can then compare performance of the current and benchmark process designs. Quantifying improvement in this way provides a useful driver to any process change initiative that is required to bring the performance of weaker units up to the best in class.
