Abstract: A general cost structure feature of multi-factory which contains fixed cost and unit cost is studied,a decentralized resource scheduling approach to multi-factory is proposed.The approach adopts the ZI2 strategy and based on market mechanism of continuous double auction.ZI2 strategy is two-dimensional bidding strategy containing price and quantity. The agents adopting the strategy submit bidding price in the range of preset price.The results of simulation experiments show that the ZI2 strategy can achieve high scheduling efficiency,and the overall average efficiency reaches 90%.
