This paper deals with the operational efficiency of companies engaged in the production of wooden chairs using selected statistical and DEA (Data Envelopment Analysis) methods. Indicators that typically characterise the supply chain in the production of selected companies were taken as input and output variables for the DEA method. They included three input variables: inventories, material costs and production services costs and one output variable: company’s net profit. The obtained coefficients of correlation pointed to a high degree of correlation between the variables, which justified the performance of an efficiency analysis using the DEA method. The study included 12 companies engaged in the production of wooden chairs. The results of the conducted analyses show that only one company had a relatively satisfactory operational efficiency (efficiency coefficient of 0.83) for the nine-year period. All other companies, especially micro and small enterprises, had unsatisfactorily low operational efficiency. Micro enterprises had the lowest operational efficiency, with an efficiency coefficient of only 0.14. Small enterprises reached the value of 0.3, and large companies 0.67. Medium companies had the most favourable efficiency coefficient of up to 0.83

• Title: Analiza učinkovitosti poslovanja tvrtki za proizvodnju drvenih stolica u Srbiji primjenom DEA metode

Abstract

U radu je analizirana učinkovitost poslovanja tvrtki za proizvodnju drvenih stolica primjenom odabranih statističkih metoda i DEA (Data Envelopment Analysis) metode. Kao ulazne i izlazne varijable za DEA metodu izabrani su tipični pokazatelji koji su karakteristični za lanac opskrbe u proizvodnji odabranih tvrtki. To obuhvaća tri ulazne varijable: zalihe, materijalne troškove i troškove proizvodnih usluga te jednu izlaznu varijablu – neto dobit tvrtke. Dobiveni koeficijenti korelacije pokazali su visok stupanj međusobne povezanosti odabranih varijabli, što potvrđuje opravdanost primjene DEA metode za analizu učinkovitosti poduzeća. Istraživanje je obuhvatilo 12 tvrtki koje se bave proizvodnjom drvenih stolica. Rezultati provedene analize pokazuju da je samo jedna od njih u posljednjih devet godina imala relativno zadovoljavajuću učinkovitost poslovanja (koeficijent učinkovitosti 0,83). Sve ostale tvrtke, posebice mikropoduzeća i mala poduzeća, imale su nezadovoljavajuće nisku učinkovitost poslovanja. U mikropoduzećima je zabilježena najmanja učinkovitost poslovanja, s koeficijentom učinkovitosti 0,14. Mala poduzeća postigla su koeficijent učinkovitosti od 0,3, a velika poduzeća od 0,67. Srednja poduzeća imala su najbolji koeficijent učinkovitosti: 0,83
