...Sifeng Liu; Yingjie Yang; Ying Cao; Naiming Xie Purpose The purpose of this paper is to review systematically the research of grey relation analysis (GRA) models. Design/methodology/approach Three different approaches, the springboard to build a GRA model, the angle of view in modelling...

.../approach The paper develops a multi‐objective inventory optimization model, which combines the classic grey prediction GM(1,1) model with the metaheuristic method. The former is applied to achieve the forecasting mechanism in supply chain operations, and the latter is applied to optimize the model...
