This paper studies a version of stochastic vehicle routing problems, in which travel and service times are stochastic, and a time window constraint is associated with each customer. This problem is originally formulated as a chance constrained programming model and a stochastic programming model...

The multi-commodity minimum disconnecting set in a given network is of considerable interest in military operations. The present known methods of finding the multi-commodity minimum disconnecting set consist of implicit enumeration techniques or techniques which involve the solution of several...
