The analysis and continuous improvement of business processes (BPs) has a strategic relevance for those enterprises that strongly rely on the performance of their operational processes to deliver services and/or goods to customers. The adoption of Modeling \& Simulation (M\&S) approaches is widely recognized as a valuable solution for analyzing and improving BPs, even though it is not yet fully exploited, due to the required know-how, effort and cost. In this context, M\&S as a Service (MSaaS) is a promising paradigm that contributes to effectively ease the introduction of M\&S approaches in the BP lifecyle, by saving the investments required to build and maintain the needed hardware and software infrastructure. This paper first illustrates a survey that analyzes the state-of-The-Art regarding the adoption of M\&S approaches in the BP domain and then, starting from a set of identified open issues, proposes a next generation MSaaS architecture which aims at enabling a time-And cost-effective M\&S-based analysis of BPs. {\textcopyright} 2017 Society for Modeling \& Simulation International (SCS).

The adoption of Modeling \& Simulation (M\&S) approaches is widely recognized as a valuable solution for enacting a timely analysis of business processes (BPs). Despite their relevance, the effective introduction of such approaches in the BP lifecycle is still limited, due to the know-how and skills for building and implementing a simulation model and to the cost and effort for setting up and maintaining the execution platform. In this respect, this paper proposes a cloud-based architecture that exploits the M\&S as a Service (MSaaS) paradigm and containerization technology for the flexible and dynamic composition of M\&S services, so to allow business analysts to carry out an effortless and effective M\&S-based BP analysis. An example case study dealing with an e-commerce scenario is also presented in order to show the actual application of the proposed approach.

Inter-organization business process collaboration is one of the most significant factors driving today{\textquoteright}s global business development. Such collaborations are typically composed by various processes executed by different organizations and are often difficult to specify and analyze, due to their distributed nature and to data interoperability issues. The standard notation for business process modeling, namely BPMN (Business Process Model and Notation), only provides a limited support to the specification of collaborations. This paper introduces a data model extension of BPMN inspired by the HLA (High Level Architecture) distributed simulation standard. In addition, the paper proposes a metamodel-based mapping from BPMN to HLA, which can be seen as a significant step towards the implementation of a conceptual framework for specifying and analyzing collaborative business processes by use of distributed simulation approaches. {\textcopyright} 2017 IEEE.

Although Systems Engineering (SE) is becoming progressively the leading discipline in the development of engineered systems, most of the functions performed by a system are {\textquoteright}delivered{\textquoteright} as services. This leads to what is referred to as Service Systems Engineering (SSE), which has its basis in the SE and, for specific types of services, represents the driving discipline to design successful systems capable of delivering effective services. In the defence market, the acquisition of defence and weapon systems is facing, in the last decades, a continuous budget contraction for both the acquisition and the support of the delivered systems. The main scope of support services, as an instance of SSE, is to define, deliver and asses the proper blend of services to ensure optimal system performance at an affordable life cycle cost. This paper introduces a model for the definition, implementation and continuous assessment of operational availability, in order to ensure that the required performance is met in a cost-effective way throughout the system lifecycle. The amount, distribution and continuous readiness of the logistic resources required to meet the target availability is the primary scope of what is referred to as performance based logistics, which this paper addresses by introducing a SSE framework to tailor, design, deliver and monitor logistic resources. {\textcopyright} 2015 IEEE.

Model-based systems engineering (MBSE) enables the effective (i.e., unambiguous) communication in the collaborative activities within concurrent engineering and service systems engineering facilities. The advantages obtained by the MBSE approach can be further scaled up by an innovative approach that take into explicit account the representation of the inter-systems aspects, i.e., those aspects, namely interfaces, that stay in between the system, its sub-systems and external entities (other systems and organizations). Such an approach, briefly denoted as a Model-based Interface Engineering (MBIE), brings several benefits to the CEF activities. This paper illustrates the integration of the Interface Communication Modelling Language (ICML) into the existing MBSE methods for the CEF software framework VirSat, by identifying the business needs driving the use of MBIE approaches and showing example application scenarios.

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.

In line with ongoing Model-based Systems Engineering (MBSE) initiatives aiming to support systems engineering activities by means of formal and graphical models, we have introduced a logical model for the definition of Interface Communication Modelling Language (ICML), to enable a model-based approach for interface specification. ICML is based on UML and can potentially be integrated with other systems models in similar forms, e.g., SySML, and with systems of systems models in UPDM or related frameworks. We have designed ICML basing on a preliminary domain analysis on radio signal specifications, with application to space systems. In the analysis, we have specifically considered simple digital and unidirectional signals, and subsequently we have included a method to use ICML for Time-Division Multiplexed signals. We also present an excerpt of the ICML metamodel and a simple example application. {\textcopyright} 2012 by Daniele Gianni et al.}, keywords = {Engineering activities, Interface specification, Model based approach, Model-based systems engineering (MBSE), Modelling language, Multiplexed signals, Specifications, Systems engineering, Systems integration, Systems of systems}, isbn = {9781622769162}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84884132292\&partnerID=40\&md5=137b25c099fd2308a19460fd8ff866b8}, author = {Gianni, D. and Andrea D{\textquoteright}Ambrogio and De Simone, P. and Lisi, M. and Luglio, M.} } @conference {Gianni201271, title = {The viewband concept: Introducing life-cycle modeling in enterprise architectural frameworks}, booktitle = {Proceedings - 2012 7th International Conference on System of Systems Engineering, SoSE 2012}, year = {2012}, note = {cited By 0}, pages = {71-76}, abstract = {Enterprise architecture (EA) frameworks have been successfully used to support enterprise engineering activities by providing graphical and machine-processable constructs to represent enterprise systems.

In this paper, we propose the Viewband concept, which can be used to explicitly introduce lifecycle modeling, thus overcoming the limitations of existing EA frameworks. We also present an overlay methodology to implement the Viewband concept by use of standard modeling structures in existing EA frameworks, thus gaining compliance with currently available technologies and documentation standards.

In the BPM context, the Business Process Modeling Notation (BPMN) is the de-facto standard for the high-level description of business processes. Unfortunately BPMN does not support the characterization of the business process in terms of non-functional properties such as performance and reliability. To overcome such limitation, this paper introduces PyBPMN (Performability-enabled BPMN), a lightweight BPMN extension for the specification of properties that address both performance and reliability. The proposed extension is based on an approach that exploits principles and standards introduced by the Model Driven Architecture (MDA), thus obtaining significant advantages in terms of easy customization and improved automation.
