Increasing pressures caused by negative consequences of transportation and traffic problems in major cities, have resulted many attempts towards improvement of planning and management of transportation systems, according to sustainability objectives. In this paper, a comprehensive model is developed using a system dynamics approach to evaluate sustainable urban transportation. This model includ...

background and goal: burn is an irreparable event, which results in numerous physical, psychological, social, and economic complications. the burned patients should be merely treated in a professional burn center due to vast clinical range of these patients. since, a percentage of mortality in burned patients is for the patients’ transportation from other centers; this study has aimed to invest...

This paper presents a high-tech solution to meet the challenges in calibrating transportation simulation models. Like any simulation software, model calibration prior to its application plays a crucial role in producing reliable results. However, transportation professionals face difficulties in performing the daunting tasks of calibrating a model for each transportation network design to satis...

Reverse supply chain is a process dealing with the backward flows of used/damaged products or materials. Reverse supply chain includes activities such as collection, inspection, reprocess, disposal and redistribution. A well-organized reverse supply chain can provide important advantages such as economic and environmental ones. In this study, we propose a general framework and formulate a m...

Laboratory turnaround time is considered one of the most important indicators of work efficiency in hospitals, physicians always need timely results to take effective clinical decisions especially in the emergency department where these results can guide physicians whether to admit patients to the hospital, discharge them home or do further investigations. A retrospective data analysis study wa...

In this paper, we analyse the special security requirements for software support in healthcare and the HealthAgents system in particular. Our security solution consists of a link-anonymised data scheme, a secure data transportation service, a secure data sharing and collection service, and a more advanced access control mechanism. The novel security service architecture, as part of the integrat...

This paper introduces the concept of accessibility from the field of transportation planning and adopts it within the context of Information Retrieval (IR). An analogy is drawn between the fields, which motivates the development of document accessibility measures for IR systems. Considering the accessibility of documents within a collection given an IR System provides a different perspective on...

This article describes a method for organizing and staffing a hospitalwide patient transportation system in such a way as to minimize patient waiting times. The method stems from a quality improvement project and includes a centralized communication system, a queuing model to determine staffing requirements, and a computerized data collection and monitoring system. A case study demonstrates imp...
