Thermometer model analysis

Figure 1.2 shows the steps that are involved in the modeling process in detail. There are three main phases system analysis, model design and model analysis. These phases can be further subdivided into smaller steps. By using the example of a thermometer, these steps will be clarified. Problems during model development are ... 

During the problem analysis phase, the environmental model is developed. This is an information flow diagram representing the process inputs and outputs as shown in Fig. 1.3 for the case of a simple thermometer. 

The result of the context analysis is an input-output model with assumptions about environmental effects that can be ignored. In the case of the thermometer it is assumed that only the medium temperature is relevant and that the heat transfer conditions are constant.
