 Prof. Joong Hoon Kim
Harmony Search Variants and Their Application to Engineering Problems

Abstract

Among optimization methods, metaheuristic algorithms have shown their capabilities for finding the near-optimal solution for which analytical methods may not be able to produce an acceptable solution within a reasonable computation time, especially when the global optimum is surrounded by many local optima. Therefore, the need of using these approaches is understood by the optimization community.
The Harmony Search (HS), published in 2001, is derived from the concepts of musical improvisations and harmony knowledge, and is considered as one of the well-known metaheuristic algorithms. So far, the HS has proved its advantages over other optimizers and there are many improved variations of the HS in the literature. In recent years, it has become obvious that the concentration on a sole optimization method is rather restrictive. A skilled combination of concepts from different optimizers can provide more efficient results and a higher flexibility when dealing with large-scale problems, especially with large scale engineering problems.
This keynote speech will first introduce the concept of Harmony Search and the potential abilities of its variants including improved and/or hybridized versions. In addition, applications to some typical engineering problems will be discussed along with the results.

Prof. Ajit Kumar Verma
A Computational Intelligence Framework for Optimal Maintenance of Large Engineering Systems

Abstract

Maintenance Optimization for Large Engineering Systems is a key area in asset management. Machinery Health Monitoring is increasingly being adopted by industries not only as a means for asset management but also for ensuring high levels of vailability with its consequent gains by ascertaining the impact in enhancing availability at plant level and in a cost effective manner. Quantification of certain features such as detect-ability and prognostic ability and a  fuzzy logic approach for doing so are presented. These features are then incorporated in a multi-objective maintenance optimization model based on Markov process and genetic algorithm, the results of which serve as decision support system for the selection of health monitoring. A demonstrative  case is presented to illustrate this idea.
