China faces the problems of abandoning wind and light environmental pollution. Energy conservation emission reduction as a new technology can effectively solve above problems. In process building Storage Services project, issue Influencing Factors is focus attention. Aiming at problem in systems, method based on gray correlation analysis proposed. Adopting this method, one avoid influence subje...

Undesired wall thickness distribution and flanging cracking easily occur in reverse drawing–flanging combined processes of steel spokes when improper process parameters are used. Thus, based on GRA (grey relational analysis) and FEM (finite element method), a GRA model for a reverse drawing–flanging combined process for high strength steel B550CL spoke was established and validated. The results...

Grey relational analysis (GRA) is a vital instrument suitable for optimal selection which can be used for modelling, forecasting and decision making. Grey theory gives reliable solution of systems in which the model is poor with little or incomplete information. This paper aims to use GRA for solving Multi Criteria Robot Selection Problems (MCRSPs). In this paper, GRA steps are implemented usin...

The higher life quality standards, the changes of habits and new well-being requirements have led to an increase in the demand for housing. Decision-making problems in construction management often involve a complex decisionmaking process in which multiple requirements and conditions have to be taken into consideration simultaneously. However, not every attribute used in multidimensional scalin...

In modern machining process, optimization technique is used to find the optimal values of input parameters and the effect of those parameters on response variables. If response parameters are more than one, Taguchi method of optimization may give different set of optimal levels for each response. In the present study, Taguchi-grey relational approach based multi response optimization has been u...
