内容简介：
    We investigates the impact of two time-based payment contracts in an assembly system that consists of one assembler and two suppliers, in which both suppliers' production times are stochastic. The assembler is able to initially select the contract type, and the suppliers have to simultaneously choose their production lead times. We show that from the supplier's perspective, on-time payment contract is always the better option, since it eliminates the horizontal decentralization from the other's. Differently, the delay payment contract is the assembler's dominant option if only he is able to set a buffer time before the consumer's demand arrives. This is because the buffer time helps the assembler to mitigate the possible delay risk that caused by the suppliers' decentralization under the delay payment contract. We also find that by using the buffer time, supply chain achieves the same service level under either the centralized condition or the decentralized condition with different payment contracts. These results are robustness to extend to the system that contains N independent suppliers.
