Abstract: Resource allocation distributes limited resources among activities so as to achieve certain objectives. Either centralised methods or distributed methods can be applied to such problems. Over the last decade, one emerging research effort evident is to investigate distribution methods due to the inherent decentralised nature of many resource allocation problems. These methods are well suited for production and supply network problems where price functions can be easily derived. However, a healthcare system considers not only the cost function, but also the appropriate level of services to the patient which is usually assessed by an efficiency index. Indeed, the potential cost savings to a healthcare institution are much greater if it is operated as efficiently as possible. Thus this paper focuses on how to make distributed resource allocation decisions among several hospitals aiming to achieve better operational efficiency for each hospital. A bi-level framework, termed multi-tool integrated methodology (MTIM) is proposed. The experimental results indicate that the MTIM is able to locate an optimal staffing configuration for each emergency room from different hospitals which achieves high operational efficiency within the available budget defined by the headquarter.
