What is clearly needed is a metric that could monitor the blend uniformity, in real time as the blend occurs. Ideally, such a process would be noninvasive to the blend process, as accurate as the offline measurement, and nonlabor intensive. There are a number of techniques that have been developed to serve as a real-time blend uniformity monitoring. Near infrared (NIR) spectroscopy is probably the most mature technology that has been applied to blend imiformity analysis and will be discussed in detail below. 

To determine which platform is most suitable for the requirements of the Real-Time Process Analysis System, the method for the comparisons presented in [32] can be generalized in the sense that the primary metrics compare the absolute performance of a system and the secondary metrics serve as and aid quantifying how efficient the performance of primary metrics are achieved. Only if the same primary metrics are used to compare two different systems, can the secondary metrics provide a relative measure. Otherwise, it is like comparing apples and oranges, since the basis of the comparison is different. 

The secondary metrics describe how efficiently the key requirements met by the primary metrics are achieved. For the Real-Time Process Analysis System they are...
