经典占线赁购决策是建立在设备使用寿命无限大的假设下进行竞争策略分析,是一种单阶段的占线决策问题。论文把设备使用寿命因素考虑进占线赁购问题,扩展单阶段占线赁购问题为多阶段占线赁购。给出了该问题的离线解;设计了等长赁购策略,证明该策略是唯一最优策略;给出了风险策略基本性质,为进一步研究多阶段占线赁购风险补偿模型奠定了基础。
The classic busy shopping decision is based on the assumption of unlimited service life of the equipment. The competitive strategy analysis is a single-stage busy decision problem. The paper takes the service life of equipment into account for the issue of take-over and acquisition, and expands the issue of single-phase take-over for multi-phase acquisition. The offline solution to the problem is given. The equal-length purchase strategy is designed to prove that the strategy is the only optimal strategy. The basic properties of the risk strategy are given, which lays the foundation for further research on the risk compensation model of the multi-stage line-of-business purchase.
