As is often the case in healthcare provision, public services may offer facilities at a hierarchy of levels in<br/>different locations, ranging from basic to specialised levels of care. In addition to efficiency objectives,<br/>with public services there is the concern of equity of provision when locating new facilities. We present,<br/>as a tool-kit for decision makers, a range of discrete hierarchical location models with bicriteria<br/>efficiency/equity objectives. These models are for use in location of facilities within hierarchical systems<br/>where a fair but efficient hierarchical service is sought. The hierarchical models have as efficiency criteria<br/>both p-median and maximal-covering types. These components are combined in a novel manner with<br/>appropriate equity objectives to give decision makers a range of choices of scenarios. We illustrate use of<br/>the models in a healthcare settin
