分析收集成本并确定永久收集时间以满足分代垃圾收集器的暂停时间目标是一个重要问题。从这样的角度出发，本文首先根据工作方案分析了垃圾收集所承受的成本，然后提出了一种垃圾收集模型。垃圾收集发生在非齐次泊松过程中，并且在时间 T 和级别 K 进行长期收集。应用退化过程和连续磨损过程技术，得出预期成本率，并通过分析和数值讨论了模型的最佳策略的四种情况。
It is an important problem to analyze the collection costs and determine tenuring collec- tion times to meet the pause time goal for a generational garbage collector. From such viewpoints, this paper analyzes the costs suffered for collections according to the working schemes firstly, and then, proposes one garbage collection model. Garbage collections occur at a nonhomogeneous Pois- son process, and tenuring collections are made at time T and at level K. Applying the techniques of degradation processes and continuous wear processes, the expected cost rate is derived, four cases of optimal policies for the model are discussed analytically and numerically.
