Technological Organization of Model Investigation

Abstract

The chapter is dedicated to the technological organization of model research, discussing two important characteristics of the computer model – adequacy (how correctly it represents the investigated object) and efficiency (requirements to the machine time and ensuring convergence of the model function to the real one). It is accepted that a model is adequate if it represents the investigated object with an acceptable approximation. Several successive steps for evaluation of the adequacy are determined during its development. The concept of the model time, which should represent the real time in the studied processes, is also discussed with determining two main variants (synchronous time and asynchronous time).The last section discusses the technical and software tools for developing computer models. The technical means are mainly hardware modeling systems (stochastic machines, multiprocessor and hybrid complexes, distributed systems). Programming tools are divided into universal and specialized programming languages are presented.
