A new optimization criterion for locating emergency medical care facilities, level-load retrieval time, is described and applied to Los Angeles County. Results are compared with those obtained by optimizing mean retrieval time. The new cirterion combines retrieval times from demand points served by each facility and patient load on each facility; it yields facility sets with average retrieval times 5 to 10 percent longer, but with much more uniform patient loads, than the sets obtained by optimizing mean retrieval time. The new criterion can be used as a complement to other planning criteria and may help reduce excessive demand on the emergency care services of overloaded facilities.
介绍了一种用于定位紧急医疗护理设施的新优化标准——均衡负荷检索时间，并将其应用于洛杉矶县。将结果与通过优化平均检索时间获得的结果进行比较。新的标准结合了每个设施服务的需求点的检索时间和每个设施上的患者负荷；与通过优化平均检索时间获得的设施集相比，它产生的设施集平均检索时间长5%至10%，但患者负荷更为均衡。新标准可以作为其他规划标准的补充，并可能有助于减少对过载设施的紧急护理服务的过度需求。
