Note: Facility location with closest rectangular distances
研究在连续平面上选址一个或多个新设施，使设施与需求区域（非点状）之间的最近距离之和最小化，适用于区域型客户或设施的选址优化。
This paper considers the problem of locating one or more new facilities on a continuous plane, where the destinations or customers, and even the facilities, may be represented by areas and not points. The objective is to locate the facilities in order to minimize a sum of transportation costs. What is new in this study is that the relevant distances are the distances from the closest point in the facility to the closest point in the demand areas. © 2000 John Wiley & Sons, Inc.
