"Excess Capacity" in Utility Industries: An Inventory Theoretic Approach
借鉴经济订货量库存模型，解释公用事业企业规划产能时的决策因素，以及为何特定时期可能持有看似过剩的产能，并论证这种产能并非真正过剩，监管机构应予以认可。
An analogous model similar to the economic ordering quantity inventory model is used to explain the factors involved in ordering and planning utility capacity and the reasons why a utility may be carrying excess capacity at a particular time. Inventory models may help explain the optimal level of system reserve margins on the grounds that carrying forward capacity leads to an analysis of a rational and equitable method of adding the reserved capacity to the rate base. Although utilities may carry more capacity than is apparently needed, such capacity may not be excess, and its existence should be recognized by the regulatory commission. 18 references, 3 figures, 1 table.
