英文摘要:
In this paper we treat a gas storage valuation problem as a Markov Decision Process. As opposed to existing literature we model the gas price process as a regime-switching model. Such a model has shown to fit market data quite well in Chen and Forsyth (2010). Before we apply a numerical algorithm to solve the problem, we first identify the structure of the optimal injection and withdraw policy. This part extends results in Secomandi (2010). Knowing the structure reduces the complexity of the involved recursion in the algorithms by one variable. We explain the usage and implementation of two algorithms: A Multinomial-Tree Algorithm and a Least-Square Monte Carlo Algorithm. Both algorithms are shown to work for the regime-switching extension. In a numerical study we compare these two algorithms.

中文摘要:
在本文中,我们将储气库估价问题视为一个马尔可夫决策过程。与现有文献不同,我们将天然气价格过程建模为一个制度转换模型。陈和福赛斯(2010)的研究表明,这样的模型非常适合市场数据。在我们应用数值算法来解决这个问题之前,我们首先确定最优注入和退出策略的结构。本部分扩展了Secomandi(2010)中的结果。了解结构可以将算法中涉及的递归的复杂性降低一个变量。我们解释了两种算法的使用和实现:多项式树算法和最小二乘蒙特卡罗算法。这两种算法都适用于区域切换扩展。在数值研究中,我们比较了这两种算法。
