Reliable facility location models consider unexpected failures with site-dependent probabilities, as well as possible customer reassignment. This paper proposes a compact mixed integer program (MIP) formulation and a continuum approximation (CA) model to study the reliable uncapacitated fixed charge location problem (RUFL) which seeks to minimize initial(More)
Railroads have been using wayside inspection technologies for many years to improve the safety and efficiency of operations. There has been a recent proliferation of new, more sophisticated, but also more costly inspection systems that are capable of detecting a wide range of subtle defects before a problem has actually occurred. This new class of "(More)
