Construction of Pseudo CRS frontier for a negative data using RTS model of Allahyar & A modified multiplier BCC model

Performance measurement of Decision Making Units (DMU) possessing an array positive and negative type input output data has been extensively researched topic in Data Envelopment Analysis. However, assessment Returns to Scale (RTS) under problem only attainable after the deliberation a Variable assumption. Steps referred earlier were indeed purported solution around vicinity Unit examination predict nature firm. The extant investigation extends research Allahyar Malkhalifeh [ Comput. Ind. Eng . 82 (2015) 78–81] identify Pseudo Constant Frontier for along with new origin based on provided data. this approach seems be ineffective create frontier multiple scenario. In regard, variation Multiplier form BCC model is proposed here detect sake designing CRS frontier. Small examples are added elaboration efficient DMUs using methods described by from model. This outcome finally validated aid multiplier Sahoo et al Eur. J. Oper. Res 255 (2016) 545–558].
