Abstract
Abstract: This paper proposes integrated data envelopment analysis (DEA) models to jointly evaluate the transport efficiency and effectiveness by measuring the efficiency scores under three aspects of technical efficiency, service effectiveness, and technical effectiveness simultaneously. The underlying reason for requiring joint evaluation is that when the transport services are produced and a portion of which are not consumed, the technical effectiveness would be less than the technical efficiency. A case study on 15 bus companies in Taipei is conducted. Results show that the number of efficient companies determined by the proposed models is fewer than that determined by conventional two-stage DEA models. It indicates a superior benchmarking power of the proposed models. Key Words : integrated DEA model, service effectiveness, technical efficiency, technical effectiveness 1. INTRODUCTION Data envelopment analysis (DEA) has been widely used to evaluate the technical efficiency or technical effectiveness of decision making units (DMUs). Numerous applications of DEA can be found in various transport fields, such as airline (e.g. Schefczyk, 1993; Charnes
