The "value of information" (VOI) is a generic term for the increase in value resulting from better information to guide management, or alternatively, the value foregone under uncertainty about the impacts of management (Yokota and Thompson, Medical Decision Making 2004; 24: 287). The value of information can be characterized in terms of several metrics, including the expected value of perfect information and the expected value of partial information. We extend the technical framework for the value of information by further developing the relationship between value metrics for partial and perfect information and describing patterns of their performance. We use two different expressions for the expected value of partial information to highlight its relationship to the expected value of perfect information. We also develop the expected value of partial information for hierarchical uncertainties. We highlight patterns in the value of information for the Svalbard population of the pink-footed goose (Anser brachyrhynchus), a population that is subject to uncertainty in both reproduction and survival functions. The framework for valuing information is seen as having widespread potential in resource decision making, and serves as a motivation for resource monitoring, assessment, and collaboration.
“信息价值”（Value of Information，VOI）是一个通用术语，用于描述由于更好的信息而导致的价值增加，或者在管理影响不确定的情况下所损失的价值（Yokota 和 Thompson，Medical Decision Making 2004；24：287）。信息价值可以用几个指标来描述，包括完全信息的期望价值和部分信息的期望价值。我们通过进一步发展部分和完全信息价值指标之间的关系，并描述它们的性能模式，扩展了信息价值的技术框架。我们使用两种不同的部分信息期望价值表达式来突出其与完全信息期望价值的关系。我们还为层次不确定性开发了部分信息的期望价值。我们强调了在斯瓦尔巴群岛的粉脚雁（Anser brachyrhynchus）种群的信息价值模式，该种群的繁殖和生存功能都存在不确定性。信息价值框架在资源决策中具有广泛的潜在应用，并为资源监测、评估和合作提供了动力。
