Leagile supply chain integrates lean supply chain and agile supply chain. In this paper, the theory of lean production and agile manufacturing are compared and analyzed, and then the leagile supply chain model and the performance evaluation system based on DEA are established. Based on the above, this paper provides an example of the evaluation system to verify the operability and effectiveness, which can provide the reference for enterprises to improve operating mode of the supply chain or develop a new leagile supply chain.

The phenomenon of waste in enterprise production process is very common, how to eliminate waste in order to reduce these costs has been become a key issue for enterprise managers. In this paper, seven waste from the point of lean production: inventory, overproduction, waiting, unnecessary transport, extra action, defective products and excess processing have been analyzed, and eliminates waste which is widespread in enterprises based on the theory of industrial engineering, lean production and other technology-AHP analyzes the effect of implementation have been used.

This paper uses heuristic algorithm to makes balance about assembly line by analyzing the flow diagram of a certain type fuel pump assembly process and dividing assembly process into operation unit. Then, the result of production line balance is analyzed by using modeling and simulation of Flexsim software . Based on the above, this paper suggests the optimum control strategy which can provide the reference for enterprises to improve work efficiency.

Green supply chain is necessary for economical sustainable development. In this paper, green supply chain and traditional supply chain are compared and analyzed, characters of green supply chain are discussed, and the harm of traditional supply chain to the environment is very serious. Then, DEA model is introduced to evaluate green supply chain. Based on the above, this paper finds out effective non-DEA enterprises by bringing the performance indicators of 12 enterprises into DEA model, which can provide the reference for enterprises to improve operating mode of the supply chain or develop a new green supply chain.
