Enterprises are in the knowledge based economic environment, and with the rapid growth of knowledge and information they will face a higher level competition on knowledge.The principles were brought forward to define and implement the knowledge value chain model and management. By using the Balanced Scorecard model and Entropy weight, a system was established to evaluate the knowledge value chain management performance in enterprises. Conclusion can be drawn as follows: knowledge value chain of enterprise is customer demand orientated, it is the link structure composed of the processes of knowledge accumulation and innovation, knowledge value chain management performance could be implemented with the reference to balanced scorecard which provides more specific direction and evaluation criteria, and entropy weight method is scientific and effective for the performance evaluation.

There is a significant gap between the safety management in the Chinese colleges and many renowned colleges in other countries. The subject of this study is how to assess the performance of health, safety, and environment (HSE) in Chinese college laboratories. The assessment system is established by three parts. First of all, HSE performance assessment indicators for laboratories in Chinese colleges are identified based on the previous studies. Then set valued iteration is used to calculate the weights of the various indicators. Following that, multiple attribute group decision-making (MAGDM) method with Pythagorean 2-tuple linguistic operators is used to assess the laboratory HSE performance in colleges. Finally, taking a college in Sichuan Province as an example, the proposed method is used to assess the laboratory HSE performance. The assessment result shows that the proposed method used in this study is practical and feasible.
