Hello - I am working on an process that has an obvious order of addition effect. I have a plugin from JMP that uses a pairwise ordering scheme that can be plugged in as a covariate factor. But, one of the components is a powder, so there is the choice to predissolve it in the solvent being used, or to add it directly as a powder. Also, there could be some benefit to having some components simultaneously, while others in order. Finally, there could be some benefit of adding some components simultaneously, but delayed, such as, for example, the addition of component A and B is 2 mins each, but we start adding B after 30 seconds of starting to add A, so there is an overlap of a minute and a half, and then B continues on for another 30 seconds.

The brief literature search I did seemed to only give either complete simultaneous addition, or completely separated addition, with no mixture of the two, nor somewhat overlapping addition between components. Is there a complete way to design this sort of thing, or is this more of an active area of research kind-of thing. If a methodology is out there, is there a straightforward way to implement it in JMP? I'm an engineer so I don't know the literature well at all, so I apologize if this is a rather trivial process.

Thanks!
