The input sequences describe the characteristics of the simulated scenarios and are to be chosen in a way to preserve the real system representativeness; while the output sequences can be used as a proof of such representativeness. Producing the appropriate input sequences and validating the output sequences against the model specification is therefore fundamental to the validation of the simulation model. In this paper, we propose an ontology-based specification of simulation input sequences. The ontology gives a methodology to formalize the sequence specification and output sequence validation by providing the semantic basis for the sequences formal description. In the model specification, the input sequences are described in terms of ontology concepts and properties values, and in the model implementation the deployed sequences can be thus automatically derived by mapping them on the ontology concepts. Sequence validation may be carried out by establishing the congruence between the ontology concepts and the deployed sequences.}, keywords = {Computer simulation, Formal Description, Input sequence, Model implementation, Model specification, Model specifications, Ontology, Ontology concepts, Ontology-based, Output sequences, Real systems, Semantics, Simulation model, Specifications}, issn = {14738031}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-78650605223\&partnerID=40\&md5=cbdaef9e43630d47be542c7b08e0d72f}, author = {Gianni, D. and Andrea D{\textquoteright}Ambrogio and Iazeolla, G.} } @conference {Gianni2008118, title = {A domain specific language for the definition of extended queueing network models}, booktitle = {Proceedings of the IASTED International Conference on Software Engineering, SE 2008}, year = {2008}, note = {cited By 7}, pages = {118-124}, abstract = {The use of design patterns and modular decomposition for the development of component-based software products brings significant improvements in terms of several quality attributes (e.g., reusability, reliability, maintainability). In addition, the modular design of interacting software components allows the foundation of a flexible Domain Specific Language (DSL) that acts as a model description language rather than a coding language, bringing significant savings in terms of development effort. This is particularly true in the field of simulation, in which the use of a common language both to represent and to simulate a given simulation model practically eliminates the need and the effort to fill the gap between the model specification and the simulator implementation. This paper introduces the design features of jEQN, a language for the specification and implementation of simulation models based on extended queueing networks. Details concerning the application of design patterns, modular decomposition and generic type parameters are also presented.}, keywords = {Coding languages, Common languages, Component-based softwares, Computer simulation, Computer simulation languages, Computer software reusability, Design, Design features, Design patterns, Domain-specific languages, DSL, EQN, Generic types, Interacting softwares, Java, Java programming language, Linguistics, Maintainability, Model description languages, Model specifications, Model-driven design, Modems, Modular decompositions, Modular designs, Quality attributes, Queueing network models, Queueing networks, Reusability, Simulation, Simulation models, Software engineering, Software reliability, Specifications, Spontaneous emission, Systems analysis, Telecommunication lines}, isbn = {9780889867154}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-58049139201\&partnerID=40\&md5=0ba8c0ea76e037065fe93e4f9456b413}, author = {Gianni, D. and Andrea D{\textquoteright}Ambrogio} }
