Jianyong Liu, Wei Geng, Xiaobo Zhao

摘要:

本文研究了一类具有启动费用的有限时间非平稳库存系统。我们详细介绍了一个算法,找到一个近似的最优策略,其基本思想是使用数值计算过程中涉及的标准方法的积分。我们提供了分析误差界,收敛到零,本文中找到的近似最优策略和最优策略,这是本文的主要贡献的成本之间。据我们所知,误差界的结果是没有发现在文献中的有限时域库存系统的设置费用。最后给出了近似最优策略的收敛结果。在本文中,算法找到上述误差界也提供。数值算例表明,本文算法的性能是令人满意的。

英文摘要:

In this paper, we consider a finite horizon non-stationary inventory system with setup costs. We detail an algorithm to find an approximate optimal policy and the basic idea is to use numerical procedure for computing integrals involved in the standard method. We provide analytical error bounds, which converge to zero, between the costs of an approximate optimal policy found in this paper and the optimal policy, which are the main contributions of this paper. To the best of our knowledge, the error bound results are not found in the literature on finite horizon inventory systems with setup costs. A convergence result for the approximate optimal policy is also provided. In this paper, algorithms to find the above error bounds are also provided. Several numerical examples show that the performance of Algorithms in this paper is satisfactory.
