This article proposes a method for identifying potential self-adequate sub-networks in the existing power distribution grid. These can be equipped with control and protection schemes to form microgrids capable of sustaining local loads during systems contingencies, thereby mitigating disasters. Towards best microgrid candidates, this work formulates chance-constrained optimal network partitioni...

We study a class of chance-constrained two-stage stochastic optimization problems where second-stage feasible recourse decisions incur additional cost. In addition, we propose a new model, where “recovery” decisions are made for the infeasible scenarios to obtain feasible solutions to a relaxed second-stage problem. We develop decomposition algorithms with specialized optimality and feasibility...

The capacitated arc routing problem (CARP) is one of the most important routing problems with many applications in real world situations. In some real applications such as urban waste collection and etc., decision makers have to consider more than one objective and investigate the problem under uncertain situations where required edges have demand for more than one type of commodity. So, in thi...

We explore reformulation of nonlinear stochastic programs with several joint chance constraints by stochastic programs with suitably chosen penalty-type objectives. We show that the two problems are asymptotically equivalent. Simpler cases with one chance constraint and particular penalty functions were studied in [6, 11]. The obtained problems with penalties and with a fixed set of feasible so...
