I want to build a surrogate model and perform sensitivity analysis for a heavy simulation. The number of inputs 5 and the number of the simulations ~= 80. The question is to perform sensitivity analysis using Morris method(with optimal trajectories and simplexes) and then build the surrogate or describe the input space better with Latin Hypercube Sampling create the surrogate model and perform sensitivity analysis on the surrogate using Sobol ? If there are any papers on this issue let me know...
