In the study of population dynamics, the predator-prey system is recognized as a vitally important aspect in natural population control. On aspect of predator-prey interactions is studied in this paper. The attack cycle of a predator is assumed to consist of four different activities, namely, search, pursuit, handle and eat, and digestion. A semi-Markovian model is proposed to obtain the number of prey devoured by a predator during the activity of a day. The advantages of a new semi-Markovian model to the queueing model developed by Curry and DeMichele (1977) is demonstrated, as the results from the semi-Markovian model are closer to Holling's (1966) experimental data than their results, which were based entirely on Poisson assumptions.
在种群动态研究中，捕食者 - 猎物系统被认为是自然种群控制中至关重要的一个方面。本文研究了捕食者 - 猎物相互作用的一个方面。假设捕食者的攻击周期由四种不同活动组成，即搜索、追捕、处理与进食以及消化。提出了一个半马尔可夫模型，以获取捕食者在一天活动期间捕食的猎物数量。结果表明，新的半马尔可夫模型相对于库里和德米凯莱（1977年）开发的排队模型具有优势，因为半马尔可夫模型的结果比他们完全基于泊松假设得出的结果更接近霍林（1966年）的实验数据。
