چکیده مقاله :
Nowadays, performance measurement is carried out through two types of methods: parameterized and non-parameterized. This research focuses on non-parametric methods, specifically those that utilize mathematical programming, to assess the performance of cement companies in the Tehran Stock Exchange (TSE) market. The coverage analysis method used in this study provides an advantage over existing methods in that it can evaluate the performance of units with multiple inputs and outputs that are not interchangeable (UMIMO). The evaluation of performance was carried out using two assumptions: "Performance against constant scale" and "performance against variable scale", based on the inputs and outputs of cement companies in the TSE. The study examined 22 cement producing companies, finding 7 efficient units according to the CCR method and 11 efficient units according to the BCC method.
