The global economic crisis has a significant impact on healthcare resource provision worldwide. The management of limited healthcare resources is further challenged by the high level of uncertainty in demand, which can lead to unbalanced utilisation of the available resources and a potential deterioration of patient satisfaction in terms of longer waiting(More)
T competitiveness and dynamic nature of today’s marketplace is due to rapid advances in information technology, short product life cycles and the continuing trend in global outsourcing. Managing the resulting supply chain networks effectively is challenged by high levels of uncertainty in supply and demand, confl ict objectives, vagueness of information,(More)
In the healthcare sector, there is a requirement for innovative solutions in managing the high levels of complexity and uncertainty within Emergency Departments (EDs). Simulation modeling is currently seen as a competent means of analyzing EDs, which allows changes effects to be understood and predicted more easily. The Balanced Scorecard (BSC), well-known(More)
Global population ageing is creating an immense pressure on hospitals to meet the growing demand for elderly healthcare services. Current demand-supply gaps results in prolonged waiting times for patients and substantial costs for hospitals due to delay in discharges. This paper uses System Dynamics (SD) methodology to map the dynamic flow of elderly(More)
Health research is one of these priorities in every economy and through this research an emphasis will be put on translational research in the context of more sustainable and efficient healthcare system (translation of operations management practices to clinical applications). Healthcare systems in general and Emergency Departments in particular around the(More)
Global population ageing is creating immense pressures on hospitals and other healthcare services, compromising their abilities to meet the growing demand from elderly patients. Current demand-supply gaps result in prolonged waiting times in emergency departments (EDs), and several studies have focused on improving ED performance. However, the overcrowding(More)
