Example text

Figure 16 shows this feature of ICAS-MoT. Decomposition, partitioning and ordering of the model equations (identifies the sub-sets of equations that need to be solved simultaneously). Degree of freedom analysis is automatically performed to ensure that the problem is not ill posed (number of equations do not match the number of unknown variables) before going to the solution step. Model solution The solution step in MoT involves the following: * * * Admin: administration of the solution procedure (drives the numerical solution procedure); Solver-link: connection to the solver specified by Admin; Resid: computes the function values for the translated equations.

Importantly, this activity will help identify the most sensitive parameters in the system in determining output changes. The information can inform issues around parameter estimation which might be used to aid validation of the model. In industrial surveys, many industries had well-established validation procedures. Around 70 per cent of respondents stated that steady-state models were readily validated, but this dropped to 35 per cent for validation of dynamic models. As well, only 40 per cent of customers were aware of the validity range of models produced.

These models are usually explicit in nature, that is, knowing T, P, n and/or b, it is possible to compute u. The connection and/or conditional equations (to be called henceforth connection equations) are also usually algebraic and may be represented as: 0 ¼ x À hðy; z; x; tÞ ð5Þ As Eq. 5 implies, some connection may be explicit (if they are not functions of x) while others may be implicit (if they are functions of x). The nature of Eqs. 4 and 5 may define the complexity of the set of equations representing a process model.
