GM-VV in Swedish

Verification, validation and accreditation (VV&A) in modelling and simulation is a process which aims to increase the credibility of simulation models and provide their users with information regarding their suitability for a given purpose. Verification is the process of determining whether a model implementation and its associated data accurately represent the developer's conceptual description and specifications. Validation is the process of determining whether a model and its associated data provide an accurate representation of the real world from the perspective of the intended uses of the model. Accreditation is an official certification that a model, simulation, or federation of models and simulations and their associated data are acceptable for a specific purpose. The VV&A process also contributes to becoming aware of errors and deficiencies in the early phases of the development of simulation models, which is of great economic value. This requires a well analyzed method for VV&A activities, which also should be tailored for the specific application. GM-VV is the name of a methodology for verification and validation (V & V) in the field of M&S. GM-VV has a complete description of processes, products and organization that should be included in a well thought out VV&A work. GM-VV is designed to evaluate the models and simulations for a specific use. By describing the utility, usefulness, cost and risks the objective is to provide a good basis for decisions on their use. GM-VV describes the definitions, methods, guidelines and techniques to manage communication and interaction between a problem-owner/stakeholder, with the needs that he has, and an M&S supplier and to analyze the risks of using M&S to solve the existing problem/need. The methodology describes and illustrates all resources needed to execute the VV&A process.
