This paper supersedes the work presented in WP.No.2014-02-06. We study the problem of allocating doctors to primary health centers (PHC). We model the problem as a multi-period uncapacitated facility location problem under uncertainty. The problem is unconventional in that the uncertainty is in...

Conventional genetic algorithms suffer from a dependence on the initial generation used by the algorithm. In case the generation consists of solutions which are not close enough to a global optimum but some of which are close to a relatively good local optimum, the algorithm is often guided a...

In this work we present a local search algorithm for the single row facility location problem. In contrast to other local search algorithms for the problem, our algorithm uses an exponential neighborhood structure. Our computations indicate that our local search algorithm generates solutions to...

Blowout Preventers (BOPs) and choke manifolds are key pieces of drilling rig equipment to prevent the uncontrolled release of potentially hazardous formation uids to surface. The blowout prevention testing problem is that of testing BOP valves to check if they are functional or not. Several type...
