Efficiency and effectiveness for non-storable commodities such as transport services represent two distinct measurements. When such commodities are produced and a portion of which are not consumed instantaneously, the technical effectiveness (a combined effect of technical efficiency and service effectiveness) would be likely less than the technical efficiency. Based on this, this thesis attempts to develop an integrated data envelopment analysis (IDEA) model that can jointly determine the overall efficiency from the aspects of technical-efficiency, service-effectiveness, and technical-effectiveness. The core logic for the proposed IDEA model is to simultaneously determine the virtual multipliers associated with the variables of factor production and consumption. The underlying properties of reasonability and uniqueness of the proposed IDEA model are proven. The applicability of the proposed model is also demonstrated with a case study. It shows that our proposed IDEA model has higher discrimination power than the conventional separat ed DEA models. |
