Abstract: To recycle and dispose the waste in production process from multiple factories efficiently, aiming at the system contained multi-factories and a recycling center, the decision makers in system were devided into two decision types. In type 1, the recycling center was the only decision maker, and two recycling models：independent recycling and joint recycling were developed. In type 2, the decision makers included all the factories and the recycling centers, and three recycling models：disperse recycling, integrated recycling and joint recycling were developed. To find the optimal disposal model, the system total cost minimization was used as target to construct formulas. In addition, a heuristic search algorithm was proposed to solve the joint recycling model. By changing the factory numbers and associated costs parameters to observe cost change of system. The experiment results showed that the joint recycling model obtained much lower total relative costs for all the systems, and when the degree of waste amount difference between factories gradually become larger, the effect of joint recycling become better.
