In the last 45 years nurse scheduling has received considerable attention in the research community. Nurse rostering can be described as a task of finding a duty roster for a set of nurses in such a way that the rosters comply with work regulations and meet the management’s requests. The objective varies from minimizing the costs of float nurses or minimizing under-staffing to maximizing the degree to which the nurses’ requests are met. In logistics, one aspect is optimization of the steady flow of materials through a network of transport links and storage nodes, and the other is, coordination of a sequence of resources, such as staffing and scheduling clinical resources. The period up to 2000 is characterized by using mathematical programming and objective functions to solve nurse rostering problem. In the period after 2000 the focus of researches aimed at solving nurse rostering and scheduling problem becomes implementation of meta-heuristics and multi-objective functions. The aim of this paper is to present the latest researches conducted in last ten years.

Modern technologies and technics nowadays play a very important role in optimizing many processes. Healthcare sector is a vital system of every country and it requires great investment and constant improvement, which makes integration with modern technologies and technics inevitable. Efficiency, speed and time savings are thus crucial for achievement of this integration. Lean RFID approach is completely new way of modeling and optimizing healthcare systems. The objective of this paper is to identify, describe and analyze recent trends in merging healthcare (Emergency Department) and Lean and RFID principles into a unique system. Obtained results indicate that the application of certain segments of Lean "thinking" significantly increases the efficiency of focused processes in healthcare. The main idea of the integration of medicine and Lean RFID approach is to constantly create and improve new values and reject all the activities that are categorized as "waste" in order to provide time savings, which are extremely important in this branch.
