Abstract
One of the most sought after objects among many enterprises is the measurement of operating efficiency. Chinese Petroleum Corporation（CPC）has adopted Responsibility Center System, taking various performance parameters to weigh the outcome of individual profit centers with the aims to confront with the challenges and impacts of oil market de-regulation and privatization. Under the Responsibility Center System, focus was on “effectiveness” rather than on “efficiency”.
As a liner programming method, the Data Envelopment Analysis（DEA） can make measurement of the evaluated unit by processing simultaneously multi-inputs/outputs. Further, DEA does not require pre-determined weighting of the input/output items, making it a rather objective and equitable analytical tool. The seven oil retailing divisions of CPC have similar business scope and market environments. This study has surveyed gas stations under Taipei Marketing districts. DEA was used to evaluate the relative operating efficiency.
This study has reviewed various items affecting efficiency of gas station operation. Through Pearson correlation analysis, six variables respective to input（Service expense, manpower expense, number of service pumps）and output（number of customer, sales volume, sales revenue）have been identified for data envelopment analysis. After tackling the result differences with that from profit center measurement the operating uniqueness of efficient gas stations was reviewed using sensitivity analysis and cluster analysis. With the aim of setting up benchmarks for other gas stations.
Among the 69 surveyed gas stations （Decision Making Unit, DMU）, 16 scored 1 on all efficiencies （production, technical and scale）， thus were classified relatively efficient DMU. Further review has shown these DMU’s success in attracting customers and increase unit sales were due to operating convenience stores or designating separate pumps for large volume customers.
Comparing the top DMUs with the top 10 service stations under Responsibility Center System, the differences are obvious. Indicating the profit-center focused on target achievement ratio. Efficiency of resources utilization was not considered.
