Optimisation problems of networking manufacturing processes

Investigation of Manufacturing Processes of the Metallic CNG Pressure Vessels

CNG vessels are used in many vehicles.  Mass production of CNG pressure vessels requires exact understanding of process effective parameters.  In this paper, the numerical analysis has been used to study the manufacturing parameters.  The entire manufacturing processes, including deep drawing, redrawing and ironing, of an aluminum liner sample of CNG pressure vessel (without spinning) have been...

Manufacturing Processes

Electromagnetic forming (EM forming or magneforming) is a type of high velocity, cold forming process for electrically conductive metals, most commonly copper and aluminum. The work piece is reshaped by high intensity pulsed magnetic fields that induce a current in the work piece and a corresponding repulsive magnetic field, rapidly repelling portions of the work piece. The work piece can be re...

Applying Extremal Optimisation To Dynamic Optimisation Problems

Uncertain Constraint Optimisation Problems

Data uncertainties are inherent in the real world. The uncertain CSP (UCSP) is an extension of classical CSP that models incomplete and erroneous data by coefficients in the constraints whose values are unknown but bounded, for instance by an interval. It resolution is a closure, a set of potential solutions. This paper extends the UCSP model to account for optimisation criteria, by defining th...

Some optimisation problems revisited

We consider some simple optimisation problems and employ a non-traditional method to solve them. We try to model both the problem and solution domains as algebraic structures, attempting to characterise the join operations on these domains. In each of the examples chosen, these structures turn out to be monoids and we make use of the homomorphisms between the problem and solution structures to ...
