Abstract

Planning the design of the emergency department (ED) is a complex process. Hospital leaders and architects must consider many complex and interdependent factors, including evolving market demands, patient volume, care models, operational processes, staffing, and medical equipment. The application of digital tools, such as discrete event simulation (DES) and space syntax analysis (SSA), allows hospital administrators and designers to quantitatively and objectively optimize their facilities. This paper presents a case study that utilized both DES and SSA to optimize the care process and to design the space in an ED environment. DES was applied in three phases: master planning, process improvement in the existing ED, and designing the new ED. SSA was used to compare the new design with the existing layout to evaluate the effectiveness of the new design in supporting visual surveillance and care coordination. This case study demonstrates that DES and SSA are effective tools for facilitating decision-making related to design, reducing capital and operational costs, and improving organizational performance. DES focuses on operational processes and care flow. SSA complements DES with its strength in linking space to human behavior. Combining both tools can lead to high-performance ED design and can extend to broad applications in health care.

Abstract

In regions with an extensive waterway network intermodal transport including inland navigation is a good alternative for unimodal road transport. Intermodal transport networks exhibit an increased complexity due to the inclusion of multiple transport modes, multiple decision makers and multiple types of load units. A discrete event simulation methodology is proposed to understand the network dynamics and analyze policy measures with the intention of stimulating intermodal barge transport. The simulation model allows to quantify a number of network properties resulting from the interaction of freight flows. The intermodal hinterland network of the port of Antwerp serves as the real-world application in this study. Various aspects in the modelling process are discussed and a first potential policy is analysed. Document type: Part of book or chapter of book

Abstract

nkara : The Department of Industrial Engineering and the Institute of Engineering and Science of Bilkent University, 1995. Thesis (Master's) -- Bilkent University, 1995. Includes bibliographical references leaves 113-114. In recent years airport congestion and delay problems have received a great deal of attention due to the rapid growth of air transportation services. Of all the elements contributing to the air terminal congestion, the Air Traffic Control problem is the best understood. In this thesis we present an object-oriented model for simulating air traffic flow at an airport. The application of objectoriented design to the simulation model construction process is identified as a need, particularly for modeling large and complex systems. Object-oriented paradigm has already demonstrated that it can help to manage the growing complexity and increasing costs of the software development. The model we present here, has been implemented on a personal computer by illustrating a major metropolitan airport. Yıldırım, İnanç M.S.
