A model is a physical, mathematical, or logical representation of a system entity, phenomenon, or process. A simulation is the implementation of a model over time. Model Based Systems Engineering (MBSE): Methodology based on processes, methods, tools to support systems engineering in a “model based”or “model-driven” context Verification, Validation, and Accreditation (VV&A) : Formal approach to assess representativeness and establish confidence in the specific model or simulation Verification: process of determining that a model implementation accurately represents the developer’s conceptual description and specifications that the model was designed to Validation: process of determining manner and degree to which a model is an accurate representation of the real world from the perspective of the intended uses of the model, and of establishing the level of confidence that should be placed on this assessment. Accreditation is the formal certification that a model or simulation is acceptable for use for a specific purpose. DEFINITIONS DEVELOPMENT vs M&S (Modeling &Simulations) (SW INTENSIVE SYSTEM ENGINEERING) DEFINITIONS - VERIFICATION vs T&E (Test & Evaluation) VERIFICATION Process to confirm that Design Synthesis has resulted in a physical architecture that satisfies system requirements. Activities: Analysis, Inspection, Demonstration & Test Test and Evaluation (T&E) Policies and procedures, that support the Verification process. Aimed to assess technical performance, specifications, and system maturity to determine whether systems are operationally effective, suitable, and survivable for intended use. Testing is the means by which objective judgements are made regarding the extent to which the system meets, exceeds, or fails to meet stated objectives. Evaluation is the iterative process, to review, analyse, and assess data obtained from testing and other means, to aid in making systematic decisions. T&E purpose is to verify technical performance, operational effectiveness, operational suitability; and it provides essential information in support of decision making. DEFINITIONS - VERIFICATION vs T&E (Test & Evaluation) Test and Evaluation (T&E) Criteria T&E policy requires independent analysis and tests to verify the system’s operational effectiveness and suitability. T&E traditionally is categorized as: Developmental T&E (DT&E), focuses primarily on technical achievement, Operational T&E (OT&E), focuses on operational effectiveness and suitability − Early Operational Assessments (EOA), − Operational Assessment (OA), − Initial Operational Test and Evaluation (IOT&E), and − Follow-On Operational Test and Evaluation (FOT&E); Live Fire T&E (LFT&E), provides assessment of the vulnerability and lethality of a system by subjecting it to real conditions comparable to the required mission CENTRO DI SUPPORTO E SPERIMENTAZIONE NAVALE ISTITUTO PER LE TELECOMUNICAZIONI E L’ELETTRONICA “Giancarlo Vallauri” INTRODUCTION DEFINITIONS SCENARIO PERSPECTIVES CONCLUSIONS SCENARIO MBSE (Model Based System Engineering) Transition to MBSE: Functional, Behavioural and Performance models MBSE vs VV&A : What about ?
