METODOLOGICKE PRISTUPY K ANALYZE EFEKTIVNOSTI ZA PREDPOKLADU NEPRESNYCH DAT: HODNOTENIE VPLYVU IKT NA EFEKTIVNOST PODNIKOV

The paper presents a survey of the most effective procedures for efficiency measures calculation using data envelopment analysis when imprecise data are present (IDEA). It pays special attention to envelopment version of IDEA model (EIDEA), proposes modification of the Zhu (2003a) procedure for converting ordinal data to exact data and applies the procedure in efficiency analysis of 193 agro-food firms when impact of ICT use is taken as an efficiency factor. Analysis results by EIDEA are compared with standard CCR DEA results. The comparison shows that the standard model underestimates efficiency what seems to be a consequence of incorrect consideration of ordinal data.
