smartSDH：基于机制的建筑控制实验研究
smartSDH: An Experimental Study of Mechanism Based Building Control
摘要：
随着物联网（IoT）技术越来越多地被部署，经常出现多个利益相关者必须协调偏好以控制共享资源的情况。我们进行了一项为期5个月的实验，名为“smartSDH”（在27名员工的办公空间中进行），用户报告了他们对头顶照明亮度的偏好。smartSDH实现了修改的Vickrey-Clarke-Groves（VCG）机制;假设用户是理性的，它激励真实的报告，实现社会期望的结果，并补偿参与者以确保与默认的外部选项（即，在没有这种机制的情况下选择的办法）。smartSDH评估了智能建筑控制背景下VCG机制的可行性，并使用照明水平满意度、激励满意度和能耗等指标评估了smartSDH的效果。虽然以前的研究表明，用户满意度的机制的理论方面，我们的实验表明完全相反。我们发现，随着时间的推移，参与者对VCG机制确定的灯光亮度和激励措施的满意度显着降低。这些数据表明，需要更现实的行为模型来设计物联网技术，并强调了从可观察的外部因素（如大气条件）估计偏好的困难。
英文摘要：
As Internet of Things (IoT) technologies are increasingly being deployed, situations frequently arise where multiple stakeholders must reconcile preferences to control a shared resource. We perform a 5-month long experiment dubbed 'smartSDH' (carried out in 27 employees' office space) where users report their preferences for the brightness of overhead lighting. smartSDH implements a modified Vickrey-Clarke-Groves (VCG) mechanism; assuming users are rational, it incentivizes truthful reporting, implements the socially desirable outcome, and compensates participants to ensure higher payoffs under smartSDH when compared with the default outside option(i.e., the option chosen in the absence of such a mechanism). smartSDH assesses the feasibility of the VCG mechanism in the context of smart building control and evaluated smartSDH's effect using metrics such as light level satisfaction, incentive satisfaction, and energy consumption. Although previous studies on the theoretical aspects of the mechanism indicate user satisfaction, our experiments indicate quite the contrary. We found that the participants were significantly less satisfied with light brightness and incentives determined by the VCG mechanism over time. These data suggest the need for more realistic behavioral models to design IoT technologies and highlights difficulties in estimating preferences from observable external factors such as atmospheric conditions.
