We are mainly interested to observe the required change of a group of parameters when another group goes under a managerial change, maintaining the score of the efficiency. In other words, this methodology provides a platform for simulating the level of some parameters against the remaining parameters for generating different scenarios, as being in demand for managers.</em></span> Data envelopment analysis (DEA), Artificial neural networks (ANN), Sensitivity analysis. 14 24 http://iors.ir/journal/browse.php?a_code=A-10-488-2&slc_lang=en&sid=1 Karamali 00031947532846001071 00031947532846001071 Yes Memariani 00031947532846001072 00031947532846001072 No Jahanshahloo 00031947532846001073 00031947532846001073 No
