This introductory tutorial gives a survey on the use of statistical designs for what if-or sensitivity analysis in simulation.This analysis uses regression analysis to approximate the input/output transformation that is implied by the simulation model; the resulting regression model is also...

This report presents final results from Mathematica’s evaluation of the Social Security Administration’s Youth Transition Demonstration projects, which provided employment-focused services and enhanced financial work incentives to youth with severe disabilities. Three of the six...

This issue brief summarizes the findings in Mathematica’s final report on the evaluation of the Social Security Administration’s Youth Transition Demonstration projects, which provided employment-focused services and enhanced financial work incentives to youth with severe...

Sensitivity analysis may serve validation, optimization, and risk analysis of simulation models.This review surveys classic and modern designs for experiments with simulation models.Classic designs were developed for real, non-simulated systems in agriculture, engineering, etc.These designs...

Generalized Response Surface Methodology (GRSM) is a novel general-purpose metaheuristic based on Box and Wilson.s Response Surface Methodology (RSM).Both GRSM and RSM estimate local gradients to search for the optimal solution.These gradients use local first-order polynomials.GRSM, however,...
