Methodology for Knowledge-Based Engineering Template Update

This paper addresses the problem of knowledge templates update in product development. A framework is developed to support template instances update process by providing a decision support system and an update strategy. An Issue-Based Information system is designed to allow the collaboration among various experts in order to solve template related problems. An ontology is used to represent and ...

Ant Colony Optimization based clustering methodology

In this work we consider spatial clustering problem with no a priori information. The number of clusters is unknown, and clusters may have arbitrary shapes and density differences. The proposed clustering methodology addresses several challenges of the clustering problem including solution evaluation, neighborhood construction, and data set reduction. In this context, we first introduce two obj...

Adjoint-based Methodology for Time-Dependent Optimization

This paper presents a discrete adjoint method for a broad class of time-dependent optimization problems. The time-dependent adjoint equations are derived in terms of the discrete residual of an arbitrary finite volume scheme which approximates unsteady conservation law equations. Although only the 2-D unsteady Euler equations are considered in the present analysis, this time-dependent adjoint m...

An Optimization-based Methodology for Release Scheduling*

Operational-level scheduling decisions on the factory floor include the release policy and the dispatching rule. Recent work by researchers suggests that factory performance depends heavily on the release policy. Several heuristic factory release rules have been developed that generate release decisions based on the status of the bottleneck machine. The heuristic rules perform very well in redu...
