Models: the fourth dimension of computer science

Abstract Models are a universal instrument in science, technology, and daily life. They function as instruments almost every scenario. Any human activity can be (and is) supported by models, e.g. reason, explain, design, act, predict, explore, communicate, collaborate, interact, orient, direct, guide, socialises, perceive, reflect, develop, making sense, teach, learn, imagine, etc. This suitability is also the basis for wide use of models modelling Computer Science Engineering. We claim that form fourth dimension Science. paper sketches systematises main ingredients study model modelling.
