Volume 2, Issue 1 , December 2012, , Pages 51-62


  In this paper, lift and drag coefficients were numerically investigated using NUMECA software in a set of 4-digit NACA airfoils. Two metamodels based on the evolved group method of data handling (GMDH) type neural networks were then obtained for modeling both lift coefficient (CL) and drag coefficient ...  Read More

Few heuristic optimization algorithms to solve the multi-period fixed charge production-distribution problem

N. Balaji; N. Jawahar

Volume 1, Issue 2 , June 2012, , Pages 77-87


  This paper deals with a multi-period fixed charge production-distribution problem associated with backorder and inventories. The objective is to determine the size of the shipments from each supplier and backorder and inventories at each period, so that the total cost incurred during the entire period ...  Read More
