In Reference [115], this research proposes a performance approximation approach FiM to model the computing performance of iterative, multi-stage applications running on a master-compute framework.
The parameters of the numerical analysis for comparing the performance of approximations 1 and 2 are presented in Table 1. Figure 2a,b shows the results in 3D graphs.

This selection allows for a performance metric approximation given by (16). 2.

Under faster manipulator performance, an approximation algorithm based on heuristics and a local search was shown to produce near-optimal harvest assignments.
We evaluated the completion time and approximation quality of each SFC, in order to choose the one that achieves the best balance between timing performance and approximation accuracy, regarding the water consumption dataset.
These results show that optimisation of parlour performance and approximation to maximum labour efficiency should be addressed differently depending on the characteristics of the farm; in some cases, an improvement in management activities is necessary.
As a consequence, in case of rapid sampling, complicated process dynamics and/or high demands on closed-loop performance, satisfactory approximation of the control signal requires a very large number of forward shift operators, and leads to poorly numerically conditioned solutions and heavy computational load when implemented on-line.
By simulation we estimate the performance of normal approximations, which, via the identity link, are special cases of our approach, and for common link functions such as the log.
