Measuring efficiency and effectiveness of transport service: a novel approach

Abstract

This paper proposes a novel approach, the dynamic integrated slack-based measure (DISBM) modelling, which can jointly measure the non-radial slacks associated with input, output and consumption variables of non-storable production process, such as transport service, which may exhibit carry-over activities in multi-period contexts. The core logic of the proposed DISBM modelling is to incorporate the dynamic slack-based measure (DSBM) technical efficiency and service effectiveness into the data envelopment analysis (DEA) modelling. A case study of Taiwanese intercity bus transport over 2007-2010 is demonstrated. The results indicate that DISBM is superior to DSBM in benchmarking power.
