Merenje efikasnosti indijskih kompanija za proizvodnju cementa korišćenjem analize razvoja podataka u periodu pre i posle recesije
Measuring the efficiency of Indian cement companies utilizing data envelopment analysis during the pre and post recession period
Sažetak
Ovaj istraživački rad je sproveden kako bi se merila efikasnost kompanija za proizvodnju cementa u indijskom okruženje korišćenjem koncepta analize podataka tokom perioda pre i posle početka recesije, odnosno tokom nedavnih globalnih previranja. U ovoj studiji uzeta su u obzir dva izlaza (koja su u vezi sa profitom i prodajom) i tri inputa vezana za troškove. U samom radu je korišćena povratna informacija koja ulazna orijentisanu promenljivu približava mernoj skali. Za merenje efikasnosti i rezultata visokih performansi različitih kompanija za proizvodnju cementa, korišćen je razvoj algoritma linearnog programiranja. U ovom radu je izvršen dodatni pokušaj analize postojanja uticaja recesije na industriju cementa, koristeći metodu korelacije ranga.
Abstract
The present research work was conducted to measure the efficiency of the cement companies in Indian Scenario by utilizing the concept of Data Envelopment Analysis during the pre and post period of recession during the recent global turmoil. In the present study two outputs (related to profit and sales) and three inputs related to cost are taken into consideration .Input oriented variable return to scale has been used for this paper. Linear program has been developed to measure the efficiency and super efficiency scores of the different cement companies. A further endeavour has been made in this paper to understand if recession really did have any impact on the cement industry by utilizing spearman rank correlation technique.
