MEASUREMENT OF THE EFFICIENCY OF SME CLUSTER USING DATE ENVELOPMENT ANALYSIS (DEA)

This study explored the efficiency of SME Cluster. We developed an efficiency model consistingof operational capital, labor cost and raw material cost as the inputs. We proposed sales revenueand assets as the outputs of the model. Furthermore, a survey was conducted by involving 83SMEs in three different clusters. These three different clusters were batik cluster, furniture cluster,and apparel cluster. These clusters had been considered as SMEs with large labor absorption andenormous productivity, particularly in the area of Central Java, Indonesia. Our result shows thatmost SMEs included in those three clusters are not efficient in operating their businesses. Themain problem is related with the cost structure, especially in costly raw materials. In addition, itis suggested to improve the performance of human resource in those SMEs.

Efficiency Evaluation and Optimization of Green Mining for Coal Enterprises Based on DEA

The principle of green mining is conservation resources, protection environment, people oriented and safety production. According own characteristics of coal industry, this paper built the input and output indicators of green mining, chose eight different coal enterprises in China as decision making units. The date envelopment analysis (DEA) was applied to evaluate and optimize the operating efficiency of coal enterprises from technical efficiency, pure technology efficiency and scale efficiency. At the same time, with an inefficiency enterprise as example, projection analysis was used to give some suggestions to optimization.
