| Based on just in time (JIT) environment, and aiming at a supply chain consist of a supplier and multiple purchasers who had deterministic various demands, procurement and supply cost minimization was used as objective function and a cost mode for both purchasers and suppliers was established. And buyers purchasing batch mummification in two different intervals have been respectively studied. Results showed that when this ratio was between zero and a critical value (enable JIT procurement cost be equal to the traditional procurement cost value), JIT purchasing total cost was more than traditional purchasing total cost, so that nieither side had the enthusiasm for the JIT mode selection. But joint procurement strategies could make JIT purchasing and supplying total cost less than the traditional one, and then could also make both sides select JIT mode. Then the analysis of how to select the required joint purchaser and the corresponding strategies were given. Finally, the above conclusions were verified by numerical examples.
