Therefore, it is important to develop feedback control techniques that operate transport-reaction processes in an economically optimal fashion in the presence of constraints in the process states and manipulated inputs.
Insights from the process domain can provide significant benefits to both the formulation and the solution of the optimization problems by targeting the best possible performance of the systems or exploiting the topological constraints in the process networks.
This, as well as the presence of constraints in the process manipulated variables, results in a complex, non-linear closed-loop system and hence, the manual tuning of the PID controllers according to some given performance specifications becomes a difficult task.
The study of [119] no only used the map-reduce model, it also allowed users to express their specific interest constraints in the process of frequent pattern mining.
This condition is transformed to a function and considered as a constraint in the optimization process.
Implementing the constraint in the positioning process provides much more precise results compared to the unconstrained case.
Furthermore, the computational cost that is associated with the application of a certain combustion model introduces another constraint in the selection process.
The method introduces neighboring fiber consistency constraint in the tracking process and reconstructs fiber pathways that have optimal tradeoff between consistency with local fiber orientation estimations and similarity with neighboring fiber segment orientations.
In this light, we formulated the TC selection problem as a constrained search based optimization task, using requirements coverage as the fitness function to be maximized (quality of the resultant suite), and the execution effort (time) of the selected TCs as a constraint in the search process.
Perhaps the biggest constraint in the design process has been the Innvelo's targeted retail price range: €10,000-15,000 ($11,000-17,000 11,000-17,000
