" The consistency of models may be conceptual or physical. In many areas of research conceptual models have become the dominating species, as conceptual models, more easily than physical ones, can be investigated by means of computing . For conceptual models to be the shared property of a research community the concepts they involve must be capable of being shared. That is the case when a consensual understanding of these concepts has been achieved or can be achieved by means of definition, examples, etc. With respect to what is shown by a conceptual model there are differences at least with respect to computer science, mathematics and logic. Mathematical models in one way or another establish a functional cohesion between entities such as input values and output values. Logical models establish an interpretation relationship between formulae and structures. Hot Model Super Models in Computer Science are largely organizational in that they show how data, a cooperation between agents, the process of creating a response to an external stimulus, an algorithm, or similar is structured. The emphasis of organization that is apparent in many models of computer science appears to be a consequence of either of the following: (1) complexity issues need to be dealt with such that a functional cohesion actually can be evaluated.

"" Model Ts in different colors were produced from 1908 to 1914, and then again from 1926 to 1927. By 1914, the assembly process for the Model T had been so streamlined it took only 93 minutes to assemble a car. That year Ford produced more cars than all other automakers combined. The Model T was a great commercial success, and for years in the late 1910s and early 1920s it was estimated that more than half of all motorcars in existence in the world were Model T Fords. In fact, it was so successful that Ford did not purchase any advertising between 1917 and 1923; in total, more than 15 million Model Ts were manufactured, more than any other model of automobile for almost a century. This record has now been surpassed by the Volkswagen Beetle, and the Toyota Corolla and Ford F-Series nameplates have both sold more. The record is currently held by the Volkswagen Golf which sold over 21,000,000 units and is still in production today. Black Hot Model It was sold in the beginning at a price of $850 when competing cars often cost $2000-$3000. By the 1920s the price had fallen to $300 (about $3,300 in 2005 inflation-adjusted dollars) because of increasing efficiencies of assembly line technique and volume. "
