In assignment problems, decision makers are often interested in not only the optimal assignment, but also sensitivity of to perturbations weights. Typically, individual weights considered. We present a novel extension traditional analysis by allowing for simultaneous variations all Focusing on bottleneck problem, we provide two different methods quantifying and algorithms each. Numerical exampl...
