One of the real problems that the simulation analyst faces is to validate the model. The simulation model is valid only if the model is an accurate representation of the actual system, else it is invalid.

Definitions: Verification is the process of determining that a model implementation and its associated data accurately represent the developer's conceptual description and specifications. Validation is the process of determining the degree to which a simulation model and its associated data are an accurate representation of the real world from the perspective of the intended uses of the model [1]. Keywords: accreditation, analysis, data, historical, SME, statistics, subject matter expert, validation, verification. A MITRE SE is expected to be able to work directly with the developer of the system and the simulation model to provide technical insight into model verification and validation. In most cases, the MITRE SE will be responsible for assisting the government sponsoring organization in the formal accreditation of the model.

Verification and validation of simulation models are discussed in this paper. Three approaches to deciding model validity are described, two paradigms that relate verification and validation to the model development process are presented, and various validation techniques are defined. Conceptual model validity, model verification, operational validity, and data validity are discussed. A way to document results is given, and a recommended procedure for model validation is presented. This is a preview of subscription content, access via your institution.

Verification and validation of computer simulation models is conducted during the development of a simulation model with the ultimate goal of producing an accurate and credible model. The developers and users of these models, the decision makers using information obtained from the results of these models, and the individuals affected by decisions based on such models are all rightly concerned with whether a model and its results are "correct". Simulation models are approximate imitations of real-world systems and they never exactly imitate the real-world system. Due to that, a model should be verified and validated to the degree needed for the model's intended purpose or application. The verification and validation of a simulation model starts after functional specifications have been documented and initial model development has been completed. In the context of computer simulation, verification of a model is the process of confirming that it is correctly implemented with respect to the conceptual model it matches specifications and assumptions deemed acceptable for the given purpose of application.

Verification and validation of simulation models Abstract: In this paper we discuss verification and validation of simulation models. Four different approaches to deciding model validity are described; two different paradigms that relate verification and validation to the model development process are presented; various validation techniques are defined; conceptual model validity, model verification, operational validity, and data validity are discussed; a way to document results is given; a recommended procedure for model validation is presented; and model accreditation is briefly discussed.

Наверняка Беккер не настолько глуп. Единственная спиральная лестница упиралась в каменную камеру квадратной формы, в стенах были проделаны узкие прорези для обозрения, но, разумеется, никакого выхода он не. Дэвид Беккер поднялся на последнюю крутую ступеньку и, едва держась на ногах, шагнул в крошечную каменную клетку. Со всех сторон его окружали высокие стены с узкими прорезями по всему периметру. Выхода. Судьба в это утро не была благосклонна к Беккеру.

Халохот отчаянно озирался, но Беккера нигде не было. Сотни людей стояли на коленях перед алтарем, принимая причастие. Может быть, Беккер был среди. Халохот внимательно оглядывал согнутые спины. Он приготовился стрелять метров с пятидесяти и продвигался .

Беккер закрыл глаза, стиснул зубы и подтянулся. Камень рвал кожу на запястьях. Шаги быстро приближались.

Verification & Validation Techniques

Нуматака введет этот алгоритм в чипы VSLI со специальным покрытием и выбросит их на массовый рынок, где их будут покупать производители компьютеров, правительства, промышленные компания. А может быть, он даже запустит их на черный рынок… рынок международного терроризма. Нуматака улыбнулся. Похоже, он снискал благословение - шичигосан. Скоро Нуматек станет единственным обладателем единственного экземпляра Цифровой крепости. Другого нет и не .

 Сядь.  - На этот раз это прозвучало как приказ. Сьюзан осталась стоять. - Коммандер, если вы все еще горите желанием узнать алгоритм Танкадо, то можете заняться этим без. Я хочу уйти.

В сердцах он швырнул трубку на рычаг. - Черт! - Фонтейн снова схватил трубку и набрал номер мобильника Стратмора. На этот раз послышались длинные гудки.
