Explain Thomas model and the parameters (A, B, C and D). Discuss
Calibration and Validation process and why do you need Excel-based Solver for
Calibration. Is Thomas model a simulation model? Explain. Is it conceptual,
physical or empirical model?
Calibration is defined as the process in which a comparison is made between the two entities available. The two entities consists of the one to be measured and other set as a standard which is used as a reference for the comparison. The instrument is then set to the particular standard
The Calibration is done in the following situations
When new instruments are used, Before taking a critical measurement, for instruments after a repair, long usage of instruments.
Validation is a process which ensures that a product or service provides the results within the acceptable range. The quality, ability to perform and other operating parameters are tested in order to verify that they are with the necessary requirements and needs
Validation is done to make sure that the buyer is given a product that meets the satisfaction, specifications, requirements, and accepted standards. Documentation must be done at the end of the process.
Thomas model is considered to be a simulation model. An excel based solver is required for Calibration, because Calibration curves are non linear in nature and this variation can be plotted for a set of standard parameters in excel based solver
