一类收费库存系统的最优控制:控制带策略的最优性

Optimal Control of a Levy Inventory System: The Optimality of Control Band Policy

Jinbiao Wu, Haolin Feng, Dacheng Yao

摘要:

我们考虑一个库存系统的状态是由一个Lévy过程建模。有两种成本--经营成本和库存控制成本。运行成本(也称为持有/惩罚成本)是根据库存状态以一定的速率连续发生的。只有在对库存状态进行干预时才会产生的库存控制成本既有固定部分,也有可变部分。我们的目标是最小化期望的无限时间范围的贴现成本。我们将其表述为随机脉冲控制问题。在我们的设置中,我们得到的分析结果是具有重要意义的。具体地说,我们建立的最优控制的存在性,我们提供的封闭形式的解决方案。更重要的是,我们证明了简单的控制带政策的最优性。此外,我们研究了受控过程的瞬态和稳态行为以及随机分解性质。

英文摘要:

We consider an inventory system whose state is modeled by a Lévy process. There are two types of costs--the running costs and the inventory control costs. The running costs (also known as the holding/penalty costs) are incurred continuously at some rate as a function of the inventory state. The inventory control costs, incurred only when interventions of the inventory state are placed, have both a fixed and a variable component. The objective is to minimize the expectation of the infinite horizon discounted costs. We formulate this as a stochastic impulse control problem. In our setting, we obtain analytical results that are of significant implications. Specifically, we establish the existence of the optimal control, and we provide the solution in closed-form. More importantly, we prove the optimality of the simple control band policy. Furthermore, we investigate the transient and the steady-state behavior of the controlled process and the stochastic decomposition property.
