  • 摘要:
      目的  旨在解决舰船等级修理周期长的问题。
      方法  结合舰船修理周期管控特点，基于关键链（CC）技术开展舰船等级修理周期管控的应用研究。通过设置缓冲区来解决修理周期的制定、实施和监控中可能遇到的问题，建立基于关键链技术的舰船修理周期管控模型，并通过实际案例验证该模型的可行性和有效性。
      结果  结果表明，在保证舰船修理质量的前提下，运用关键链技术将某舰主机大修周期缩减了近63%。
      结论  将关键链技术应用于舰船等级修理周期管控，不仅丰富了其理论体系，而且对于优化舰船修理周期管控、提高舰船在航率具有重要意义。

     

    Abstract:
      Objectives  This paper aims to solve the problem of the long scheduled maintenance duration of warships.
      Methods  Combining the characteristics of the maintenance management and control of warships, research on the application of scheduled maintenance cycle management and control for warships is carried out based on critical chain project scheduling. A "buffering period" is set to solve the problems that may be encountered in the formulation, implementation and monitoring of the maintenance cycle, and a management and control model of the maintenance cycle of warships is established on the basis of the critical chain method （CCM）. The feasibility and effectiveness of this model are then verified through actual case calculations.
      Results  The results show that the use of CCM can reduce the overhaul period of a main engine by nearly 63% while ensuring maintenance quality.
      Conclusions  The application of CCM to the management and control of warships scheduled maintenance cycle not only enriches the theoretical system, but also has great significance for optimizing the management and control, and improving operational availability of warships.
