Optimal technology selection considering input levels of resource

摘要

Purpose - The purpose of this paper is to propose an optimal technology selection (OTS) method considering technology alternatives' required input levels of resource, to help companies select an optimal technology. Design/methodology/approach - The proposed method clustered technology alternatives according to their required input levels of resource. After that, in each cluster, the proposed method used data envelopment analysis-assurance region (DEA-AR) and analytic hierarchy process (AHP) rating method to evaluate the efficiencies and priorities of the technology alternatives, respectively. Finally, combined scores of the technology alternatives were calculated. A company can choose a proper technology cluster, and then select the technology alternative with the highest combined score within the selected cluster as the optimal technology. Findings - The results showed that the OTS method cannot only select suitable technology which accords with a company's actual input capabilities, but also provide a more accurate selection result. Originality/value - Traditionally, technologies are evaluated without considering the technologies' required input levels, and simply ranked for selection. However, there are differences between a company's actual resource levels and a selected technology's required input levels of resource. This study proposes an integrated method to evaluate technology systematically and provides a more reasonable selection process for selecting optimal technology.
