Operational Competitiveness Rating
The Operational Competitiveness Rating (OCRA) is a technique for benchmarking , performance measurement and efficiency analysis from the field of operations research , i. H. the development and use of quantitative models and methods for decision support. It is used to compare the performance or efficiency of organizational units or production units (PUs).
General description of OCRA
OCRA was developed by Celik Parkan in 1994 . Since then, OCRA has been applied to banks, hotels and factories, for example. These PUs are represented in OCRA by inputs and outputs. For each PU, OCRA provides an inefficiency index. With these inefficiency indices, the PUs can be ranked.
OCRA is available in many different versions. On the one hand, these are mathematically complex versions that use linear programming and are similar to Data Envelopment Analysis (DEA). On the other hand, there is a simple version that is very similar to TOPSIS (Technique for Order Preference by Similarity to Ideal Solution).
The specification of criteria weights for inputs and outputs can be made with the help of the Analytic Hierarchy Process or the Analytic Network Process .
