本文关注的是在一个简单的设施选址问题的权重，总结成本和体积参数，是随机抽取的多元概率分布的完美信息（EVPI）的期望值。使用具有矩形距离的模型和具有平方欧几里德（重心）的模型。该分析是为权重的多元正态分布而开发的，但模拟用于表明，导出的表达式对于其他分布是相当准确的（示出了多元对数正态分布的EVPI）。
This paper is concerned with finding the expected value of perfect information (EVPI) in a simple facility location problem where the weights, which summarize cost and volume parameters, are random draws from a multivariate probability distribution. A model with rectangular distances and one with squared Euclidean (center of gravity) are used. The analysis is developed for a multivariate normal distribution of weights but simulation is used to show that the expressions derived are reasonably accurate for other distributions (the EVPI for the multivariate lognormal distribution is illustrated).
