Chapter
Intercity traveling has been recognized as a leading cause for the continuation of the COVID-19 global pandemic. However, there lacks credible prediction of the spatiotemporal spread of COVID-19 with humans traveling between metropolitan areas. This study attempts to establish a novel framework to simulate human traveling and the spread of virus ac...

Electronic Health Records (EHRs) exhibit a high amount of missing data due to variations of patient conditions and treatment needs. Imputation of missing values has been considered an effective approach to deal with this challenge. Existing work separates imputation method and prediction model as two independent parts of an EHR-based machine learni...

Background Reinforced by the COVID-19 pandemic, the capacity of health systems to cope with increasing healthcare demands has been an abiding concern of both governments and the public. Health systems are made up from non-identical humans and physical components interacting in diverse ways in varying locations. It is challenging to represent the fu...
Chapter
Hospitals and health services are complicated places that generate large quantities of data focusing on individual patient care. That care is the product of multiple interactions between patients and the many differently staffs within a hospital or health service. It is hard to use the data produced by hospitals and health services to adequately re...

Background: Hospital congestion is a common problem for the healthcare sector. Numerous studies explored reasons for crowding within some parts of the hospital. However, to deal with more general, hospital-wide problems, examining the hospital as a connected whole is necessary. The purpose of this study was to evaluate de-congestion interventions t...
Preprint
The impact of the outbreak of COVID-19 on health has been widely concerned. Disease risk assessment, prediction, and early warning have become a significant research field. Previous research suggests that there is a relationship between air quality and the disease. This paper investigated the impact of the atmospheric environment on the basic repro...
Chapter
It is beyond the capacity of the human mind to process large amounts of interdependent information, such as predicting the dynamic behavior of a complex system and evaluating the short and long term effects of potential interventions aimed to improve its operations. At the same time, it is extremely costly to test these interventions with the real...
Chapter
Hospitals are dynamic environments that involve many stochastic processes. Each day, some patients are discharged from hospital, emergency patients arrive and require admission, and a variable number of elective admissions are planned for the day. The ability to forecast hospital occupancy will assist hospital managers to balance the supply and dem...
Article
Full-text available
In this study, we define a hospital congestion episode as a situation where the number of new patients needing admission is greater than the number of available beds in the hospital, and investigate the likelihood that the current day’s midnight occupancy will exceed any specified threshold level. We demonstrate that this measure of risk exhibits a...
Article
Background: Increasing demand for hospital services has resulted in more arrivals to emergency department (ED), increased admissions, and, quite often, access block and ED congestion, along with patients' dissatisfaction. Cost constraints limit an increase in the number of hospital beds, so alternative solutions need to be explored. Aims: The ai...
Article
In this paper we outline the design, development and application of a hospital patient flow management support tool – Hospital Event Simulation Model: Arrivals to Discharge (HESMAD). The model captures the patterns of patient flows within Flinders Medical Centre, a teaching hospital located in South Australia, through extensive exploitation of an e...

This study is the first to explore the quality of care based on the outlier or the inlier status of patients for a large heterogeneous General Medicine (GM) service at a busy public hospital. The study compared the quality of care between ward outliers and ward inliers based on a homogenous group of patients using Two-step clustering method. Contra...
Article
The discrepancy between the number of admissions and the allocation of hospital beds means that many patients admitted under the care of a general medical service can be placed in other departments' wards. These patients are called ‘outliers’, and their outcomes are unknown. To examine the relation between the proportion of time each patient spent...
Conference Paper
Full-text available
Hospitals are continually struggling to cater for the increasing demand for inpatient services. This is due to increased population, aging, and the rising incidence of chronic diseases associated with modern life. The high demand for hospital services leads to unpredictable bed availability, longer waiting period for acute admission, difficulties i...
Article
Purpose – The use of capability maturity model integration (CMMI) on its own can be problematic for the organisation because it does not provide a roadmap to implementation or identification of key process improvement areas, but instead only provides the goals for each level of implementation. Addition of another framework such as control objective...

The establishment of an existing practice scenario was an essential component in providing a basis for further research in the area of COTS software acquisition within the organisation. This report details the identification of means of describing the existing practice of software acquisition within an organisation and identification of models that...
Article
Autonomous moving objects (AMOs), such as automated guided vehicles (AGVs) and autonomous robots, have widely been used in the industry for decades. In an intelligent transport system with a great number of AMOs involved, it is important to eliminate potential congestion and deadlocks among AMOs to maintain a well-organized traffic flow. In this pa...
Conference Paper
Many organizations have to outsource some of their data mining tasks due to inadequate in-house IT expertise. During this process, the organizations lose full security control of their source data which may lead to the exposure of their business privacy. In this paper, we first present different application scenarios of outsourcing computing tasks...
Conference Paper
Business process modeling can be used as an effective tool to understand requirements of software acquisition. This paper examines the current literature on the practices and their associated benefits and challenges in making software acquisition decisions with business process modeling, and demonstrates the need for further research in this area.
Conference Paper
This paper proposes a practical process for project cost estimation in a small studio game development environment, based on a study of the current estimation methods and estimation tools available in the software industry. The process involves profiling common team composition and common small studio project types. It contains an eight step guide...
Conference Paper
Approaches to software process development that are based on the principles and practices of software engineering have been advocated by many researchers as a means to produce software processes that meet the needs of process users. Such approaches require methodical and repeatable verification and validation techniques that enable effective and ef...
