Customer Preferences for Reliable Power Supply: Using Data on Actual Choices of Back-Up Equipment
利用日本大型计算机用户备用设备调查数据，通过离散选择模型分析客户对电力可靠性的偏好，发现价格与可靠性存在权衡，且行业类型和用电量显著影响选择，金融和通信行业更关注可靠性。
This paper empirically examines customer preferences for the reliable sources of electricity using data obtained from a survey of back-up systems owned by large computer users in Japan. The empirical results based on probabilistic discrete choice models indicate that (1) customers face a trade-off between the price and the reliability of the power supply, and (2) customer characteristics, such as types of business and levels of electricity usage, have significant impacts on the choice of back-up apparatuses. The estimates of cost changes that would offset reliability changes imply that the financial and communications sectors are more concerned about reliability than are other sectors.
