    Abstract: Foundry operatives have been conducting laboratory tests physically and characterizing silica sand of river bed for moulding purposes with a view to ascertaining their properties. This has made flexibility and speed of decision-making difficult during moulding practice. This study was aimed at developing a model and simulation for estimating the mo... Show More

    Abstract: After the huge East Japan Earthquake, many steel structures have been constructed using welded frame welded joints and welded foundation construction. Although steel-frame structures are regarded as earthquake-resistant structures, many steel-frame structures are built using fillet-welded frame-welded joints and welded column bases. These welded jo... Show More

    Abstract: Data Envelopment Analysis (DEA), as a non-parametric technique for evaluating the relative efficiencies of a set of homogenous decision-making units (DMUs) with multi-inputs and multi-outputs, is widely used in the performance evaluation field. This paper develops a new DEA cross-efficiency method based on consensus (CEC-DEA), which can be more rea... Show More
