Research on inventory sharing model of frequent mining machinery maintenance spare parts

For the problem of high inventory level of mining machinery maintenance spare parts in the enterprises, an inventory sharing model is built based on distributed storage and ordering strategy of (R, S). To manage the spare parts inventories, a shared alliance center is established in the enterprises according to the inventory and order point. The centralized ordering model is established in order to minimize the inventory cost, and the optimal order quantity is solved by genetic algorithm.
