近年来，消费者浪费的持续增长严重威胁着环境。具有环保意识的制造和产品回收已成为对环境和社会的义务。许多国家正在考虑制定法规，迫使制造商从消费者手中收回用过的产品，以便从产品中回收的部件和材料可以重新使用和/或回收。我们专注于再制造系统中的产品回收系统。产品回收的目的，是透过循环再造和再制造的方法，从旧或过时的产品回收物料和零件，以减少送往堆填区的废物量。在设计和管理制造系统时应考虑这一点。本文提出了一种新的分析方法来评估具有随机变异性的产品回收系统。该模型将传统的库存理论应用到生产/库存管理中，考虑了产品的报废和退货。该系统是由一个离散时间马尔可夫链。它由库存数量表示的状态、状态之间的转移概率以及与转移相关的成本组成。利用马尔可夫分析，我们可以准确地计算出每个周期的总期望平均成本。最后通过数值算例说明了该管理系统的性能，并对产品回收系统进行了优化。
The continuous growth in consumer waste in recent years has seriously threatened the environment. Environmentally conscious manufacturing and product recovery has become an obligation to the environment and to society. Many countries are contemplating regulations that force manufacturers to take back used products from consumers so that the components and materials retrieved from the products may be reused and/or recycled. We focus on a product recovery system in a remanufacturing system. Product recovery aims to minimize the amount of waste sent to landfills by recovering materials and parts from old or outdated products by means of recycling and remanufacturing. It should be considered when designing and managing the manufacturing systems. We propose a new analytical approach to evaluating the product recovery system with stochastic variability. This model applies the traditional inventory theory to the production/inventory management with consideration for disposal and return. The system is formulated by a discrete time Markov chain. It is composed of the states denoted by the number of the inventory, the transition probabilities between states and the costs associated with the transitions. Using the Markov analysis, we can calculate the total expected average cost per period exactly. Numerical examples are given to show the property of the management system and optimize the product recovery system.
