Stakeholder engagement in simulation projects is important, especially in healthcare where there is a plurality of stakeholder opinions, objectives and power. One promising approach for increasing engagement is facilitated modelling. Currently, the complexity of producing a simulation model means that the {\textquoteleft}model coding{\textquoteright} stage is performed without the involvement of stakeholders, interrupting the possibility of a fully facilitated project. Early work demonstrated that with currently available software tools we can represent a simple healthcare process using Business Process Model and Notation (BPMN) and generate a simulation model automatically. However, for more complex processes, BPMN currently has a number of limitations, namely the ability to represent queues and data-driven decision points. To address these limitations, we propose a conceptual design for an extension to BPMN (BPMN4SIM) using model-driven architecture. Application to an elderly emergency care pathway in a UK hospital shows that BPMN4SIM is able to represent a more complex business process. {\textcopyright} 2017 The Operational Research Society

Healthcare organizations are increasingly pushed to improve the quality of care service taking into account the increasing complexity in patient treatment and the continuous reduction of available resources. The adoption of Business Process Management (BPM) practices is thus becoming a key enabler for the improvement of healthcare processes (HPs). Accordingly, methods and tools are required to address behavioral and performance aspects from the early phases of the process lifecycle in order to improve the quality of healthcare, reduce costly reworks and increase the effectiveness of BPM approaches. This paper specifically addresses the specification and analysis phases of the process lifecycle and introduces a model-driven method for healthcare process simulation. The proposed method is based on a model transformation approach that takes as input the process specification in BPMN, appropriately extended to include the performance properties of the process, and yields as output the corresponding process simulation code, ready to be executed. In order to illustrate the method and its effectiveness, the paper describes an example application to a process dealing with the hip fracture for elderly patients. {\textcopyright} 2016 IEEE.

Approaches founded on the use of modeling languages and frameworks are grouped under the banner of MBSE (Model Based Systems Engineering). The basic idea is that a model evolves over the system development life-cycle, until it becomes the built-to baseline. In this paper, we consider a modeling approach based on the use of a metamodeling architecture that focuses on the use of models as the primary artifacts of system development. We specifically address the use of MDA (Model Driven Architecture), which allows to increase the level of automation when evolving models from the very abstract representation of a system down to the system implementation, thus making easier (i.e., at reduced cost and effort) the analysis, development and testing activities. By applying MDA concepts and standards to MBSE approaches we obtain what we refer to as MDSE (Model Driven Systems Engineering). The paper illustrates a methodological template for MDSE and shows its application to the development of a software-intensive system.

This paper deals with the CASE document alternative. After a brief overview of existing automatic derivation methods, it introduces a method that unifies existing techniques that use CASE documents. The method is step-wise clear, can be used from the early phases of the software lifecycle, is distributed-software oriented, and can be easily incorporated into modern (e.g., UML-based) CASE tools. The method enables the software designer with no specific knowledge of performance theory to predict at design time the performance of various final product alternatives. The designer does only need to feed the CASE documents into the performance model generator. The paper carries on an application case study that deals with the development of distributed software, where the method is used to predict the performance of different distributed architectures the designer could select at preliminary design time to obtain the best performing final product. The method can be easily incorporated into modern object-oriented software development environments to encourage software designers to introduce lifecycle performance validation into their development best practices. {\textcopyright} 2001 Elsevier Science B.V.}, keywords = {Computer aided software engineering, Computer architecture, Distributed computer systems, Distributed software, Systems analysis, User interfaces}, issn = {01665316}, doi = {10.1016/S0166-5316(01)00036-0}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-0035400344\&partnerID=40\&md5=c4fbe1a264e5fde474ce1c0eabbaedcb}, author = {Cortellessa, V. and Andrea D{\textquoteright}Ambrogio and Iazeolla, G.} }
