Hospital Emergency Department Simulation for Resource Analysis
Erhan Kozan,Mel Diefenbach 대한산업공학회 2008 Industrial Engineeering & Management Systems Vol.7 No.2
The Emergency Department (ED) is an integral part of hospitals. Admissions from the ED account for a significant proportion for a hospital’s activity. Ensuring a timely and efficient flow of patients through the ED is crucial for optimising patient care. In recent years, ED overcrowding and its impact on patient flow has become a major issue facing the health sector. Simulation is rapidly becoming a tool of choice when examining hospital systems due to its capacity to involve numerous factors and interactions that impact the system. An analytical simulation model is used to investigate potential impacts by changing the following aspects of ED (physical layouts; number of beds; number and rate of patient arrivals; acuity of illness or injury of patients; access to radiology and pathology services; hospital staffing arrangements; and access to inpatient beds). Results of a significant numerical investigation at a hospital are also presented.

An Interactive Planning and Scheduling Framework for Optimising Pits-to-Crushers Operations
Shi Qiang Liu,Erhan Kozan 대한산업공학회 2012 Industrial Engineeering & Management Systems Vol.11 No.1
In this paper, an interactive planning and scheduling framework are proposed for optimising operations from pits to crushers in ore mining industry. Series of theoretical and practical operations research techniques are investigated to improve the overall efficiency of mining systems due to the facts that mining managers need to tackle optimisation problems within different horizons and with different levels of detail. Under this framework, mine design planning, mine production sequencing and mine transportation scheduling models are integrated and interacted within a whole optimisation system. The proposed integrated framework could be used by mining industry for reducing equipment costs, improving the production efficiency and maximising the net present value.
