|dc.description.abstract||In this study, using the Data Envelopment Analysis（DEA）, to research the status of the operating performance of the tire industry in Taiwan, and hope through the DEA efficiency assessment methodology, managers can fully understand the effects of the use of resources, as well as the next stage of improvement of the decision-making reference. In this study, to collect the listed tire manufacturer in Taiwan from 2006 to 2011 input and output values of the variables to analyze the operating performance of the tire manufacturers in the past six years, the BCC model in DEA method as a performance evaluation model. This analysis method can handle a wide range of input and output calculations, and thus the relative efficiency mode. In this study, domestic tire manufacturers take the operating costs and operating expenses as input variables; net operating income as the output variables, and deduce the relative relationship of input and output mode, deduce the returns to scale of domestic tire manufacturers and performance relationship.
This study also hope to analyze, to gain insight into the company - Nankang Rubber Tire in terms of research results, whether the relative efficiency for the relative inefficiency, through comparison with the relative efficiency benchmarking and improvement; relatively efficient, through the recommendations of the present study, the continuation of the company’’s future operating performance.
