The potential of Genetic Algorithmic (GA) approaches for solving order-based problems including the Traveling Salesman Problem (TSP) is recognized in a number of recent studies. By applying various GAs, these studies developed a set of unresolved GA design and configuration issues. The purpose of this study is to resolve the conflicting GA design and(More)

Solid-phase extraction (SPE) is often used for preconcentration and determination of metal ions from industrial and natural samples. A traditional single variable approach (SVA) is still often carried out for optimization in analytical chemistry. Since there is always a risk of not finding the real optimum by single variation method, more advanced(More)
A simple and rapid method was applied for extraction, preconcentration and determination of trace amounts of gold and palladium in wastewater by using functionalized mesoporous silica. Extraction was investigated on adsorbents prepared by grafting aminopropyl on the surface of MCM-41 and MCM-48 mesoporous silica. The optimum experimental conditions such as(More)
any organizations have wrestled with the issues of inventory locations and stocking levels. When it is critical to have inventory available for customers, the traditional approach has been to place a large amount of inventory at all locations. Carrying an excessive amount of inventory achieves a high service level, but can be enormously costly, especially(More)
Reverse logistics, the movement of materials back up the supply chain, is being recognized by many organizations as an opportunity for adding value. While global environmental concerns have been the motivation for initiating the field of reverse logistics, businesses have discovered that valuable commercial opportunities are embedded in reverse logistics.(More)
Companies competing in today’s global economy are challenged by two critical yet conflicting issues related to their supply chains. On one hand, they are under ongoing pressure to reduce operational and inventory costs, which requires keeping inventory levels low. On the other hand, they must achieve a high customer service level by having inventory(More)
