This paper presents a multi-perspective approach to Modeling and Simulation (M&S) of Healthcare Systems (HS) such that different perspectives are defined and integrated together. The interactions between the isolated perspectives are done through dynamic update of models output-to-parameter integration during concurrent simulations. Most often, simulation-based studies of HS in the literature focus on specific problem like allocation of resources, disease propagation, and population dynamics that are studied with constant parameters from their respective experimental frames throughout the simulation. The proposed idea provides a closer representation of the real situation and helps to capture the interactions between seemingly independent concerns - and the effects of such interactions - in simulation results. The article provides a DEVS (Discrete Event System Specification)-based formalization of the loose integration of the different perspectives, an Object-Oriented framework for its realization and a case study as illustration and proof of concept.

Answering Questions

The domain of healthcare is characterized by a high degree of complexity and a diversity of perspectives, and modelers are often confronted with the challenge of formulating a simulation model that captures this complexity in a systematic and manageable manner. Most often, the diverse perspectives of healthcare systems are studied in isolation and using specific formalisms. As it turns out, answering questions concerning behavioral properties of the overall system becomes difficult and therefore not sufficient for an efficient design and analysis of the system under study. In this article, we propose a framework for multi-paradigm modeling and holistic simulation of healthcare systems. We present a modeling methodology with a plethora of formalisms to allow the modeler to choose an appropriate formalism at a given level of abstraction while model transformation relates the different formalisms. Furthermore, we develop an integrative approach for the interactions between models of different perspectives through dynamic update of model output-to-parameter integration during concurrent simulations. Such an approach provides multiple levels of explanation for the same system, while offering, at the same time, an integrated view of the whole. The framework has successfully been applied to study part of the Nigerian healthcare system.

TARA (Topology Aggregating Routing Architecture) is a novel architecture which allows to generate a map of the Internet. TARA allows to maintain and compute a precise topology of the near surrounding and lesser zoomed topologies the more remote they are. In the context of TARA, nodes are identified with “locators” which are derived from longitude/latitude degrees/minutes/seconds. TARA is designed to satisfy advanced traffic engineering such as computing QoS-inferred paths or non congested paths. TARA achieves these goals without requiring an increase of RIBs and FIBs. TARA solves also the issues of dynamic update churn as currently experienced in BGP-based Internet. TARA is also designed with mobility requirements in mind. Indeed, Mobility is supported without requiring dependency on home agents or care-of-address servers. Note, the Time-To-Live mechanism is neither needed nor used in TARA-forwarding. TARA supports various multicast, broadcast, MP2P (multipoint-to-point), anycast and MP2MP (multipoint-to-multipoint) communication schemes. In particular a stateless concept for multicast is outlined; this concept may serve as a pattern for anycast and MP2MP applications. TARA is fully prepared to cope with the IPv4-unicast address depletion issue.

Single Gaussian background modeling is often used in the static scene. In order to overcome the deficiency of the traditional single Gaussian background subtraction method, an improved adaptive background modeling algorithm was proposed. First, the number of each pixel in the image determined as foreground that were as the parameters of each pixel update rate were counted respectively. So the original fixed update rate was transformed into the dynamic update rate changing with the parameter. In this way, the phenomena of ghosting and shelling was suppressed effectively in the traditional single model of Gauss. Finally, foreground objects were obtained by using the method of shadow removal based on morphological reconstruction. The experimental results indicate that the algorithm can quickly and accurately establish and update the background model, and extract the moving object effectively. Compared with existing approaches, experimental results with different real scenes demonstrate the robustness of the proposed method.

Product configuration design and simulation analysis are of critical importance in the rapid response to performance-driven product design. Product configuration design is the transition from customer specifications into physical solutions, while simulation analysis compared with testing result explains that physical solutions are correct and applicable to engineering. Configuration rules play an important role in the product configuration design. Finite element analysis (FEA) has been used widely in the simulation analysis. We could regard the simulation data of FEA as the important knowledge source of configuration rules. Then, a methodology of integration between product configuration design and simulation analysis is proposed to realize the dynamic update of configuration rules. An application of a clamping unit of injection molding machine that illustrates the proposed approach is developed at the end of the paper.

Individual Spacelab experimenters are responsible for developing their CRT display formats and interactive command scenarios for payload crew monitoring and control of experiment operations via the Spacelab Data Display System (DDS). In order to enhance crew training and flight operations, it was important to establish some standardization of the crew/experiment interface among different experiments by providing standard methods and techniques for data presentation and experiment commanding via the DDS. In order to establish optimum usage guidelines for the Spacelab DDS, the capabilities and limitations of the hardware and Experiment Computer Operating System design had to be considered. Since the operating system software and hardware ware design had already been established, the Display and Command Usage Guidelines were constrained to the capabilities of the existing system design. Empirical evaluations were conducted on a DDS simulator to determine optimum operator/system interface utilization of the system capabilities. Display parameters such as information location, display density, data organization, status presentation and dynamic update effects were evaluated in terms of response times and error rates.
