In this paper, we revisit the multi-item economic order quantity inventory model (MI-EOQ) under uncertainty, arbitrariness and randomness. To solve such a problem, we use the signed distance ranking function methodology. In our approach, we quantify the model parameters in the MI-EOQ inventory model by fuzzy distribution function rather than random variables. Numerical examples are provided towards the end of the paper to illustrate the salient point in the model formulation. The proposed methodology to the MIEOQ inventory model can be easily extended to other more complex inventory models whose models parameters cannot be obtained precisely.
