Progressive hedging as a meta-heuristic applied to stochastic lot-sizing

Article Abstract:

Research is presented concerning the use of stochastic programming methods which include the progressive hedging algorithm of Rockafellar and Wets. The use of the algorithm within a meta-heuristic framework is discussed.

A stochastic dynamic programming model for scheduling of offshore petroleum fields with resource uncertainty

Article Abstract:

The problem of scheduling natural gas distribution from offshore fields over different pipelines is investigated. To this end, the problem is recast in a stochastic, dynamic programming framework to account for resource uncertainty in the fields. This model, which has been numerically tested, has two objective functions, namely, to minimize the expected deviation between market demand and deliveries and maximizing expected net present value.

Proposals for chunking and tabu search

Article Abstract:

Theories and proposals for chunking, which is grouping basic units of information to create higher level units, are presented. Tabu search, which is based on a local improvement scheme that involves alteration of one or more attributes of fully specified solutions at each iteration, proves very useful in solving hard optimization problems.
