In 8] a new model validation method was proposed that is based on the estimation of an unbiased model of the model error which relates the inputs to the simulation errors. In this paper, we extend this methodology to closed-loop validation , i.e. the validation of an open-loop model on the basis of closed-loop validation data. We show that, perhaps surprisingly, the same model may fail to be va...

Statistical models can play a crucial role in decision making. Traditional model validation tests typically make restrictive parametric assumptions about the model under the null and the alternative hypotheses. The majority of these tests examine one type of change at a time. This paper presents a method for determining whether new data continues to support the chosen model. We suggest using si...

The memory hierarchy model is a powerful tool that can separate the stall time in a multi-level cache. However, since no tool currently exists that is able to compute this information, it is diicult to validate the model. In this respect, a processor simulator can help. With a simulator, we can directly observe the stall time due to cache misses, and thus obtain cpi 0. We succesfully validate t...

In this paper we outline practical techniques and guidelines for verifying and validating simulation models. The goal of verification and validation is a model that is accurate when used to predict the performance of the real-world system that it represents, or to predict the difference in performance between two scenarios or two model configurations. The process of verifying and validating a m...

The case study is based on ISO 14001 and compares the validation with other certified industries. In view of the above, response has been collected to have further improvements through developed model which was prepared based on the factorization of various input and output variables which is linked to the clauses of ISO 14001. The developed model has represented almost all the clauses of ISO 1...

Purpose: The aim of this study was to validate the model of professional citizen education in education. Methodology: The present study was applied in terms of purpose and quantitative in terms of data collection and was conducted using a descriptive survey research method. The statistical population of the study was all line managers and education staff in Khorasan Razavi province in 2019. Ac...

The discipline of mathematical model validation is increasing in importance as the value of accurate models of physical systems increases. The fundamental activity of model validation is the comparison of predictions from a mathematical model of a system to the measured behavior of the system. This discussion motivates the need for model validation and introduces some preliminary elements of mo...

In the current warfighting environment, the military needs robust modeling and simulation (M&S) to support Irregular Warfare (IW) analysis across the range of tactical, operational, and strategic levels of warfare to help inform decisions concerning operations within the IW environment. In support of this need, the military requires a responsive family of Models, Methods, and Tools (MMT) able t...
