In this paper MIP(Mean Inventory Period) Model and OMMIP decision flow have been developed. MIP model can calculate mean inventory period Which is subject to the order quantity alternative plan. OMMIP decision flow leads how can decide the most minimized order quantity in mean inventory period among various order quantity alternatives. This paper also suggests how to select the order quantity with minimum inventory period as optimal order quantity by means of comparison each mean inventory period with other mean inventory period,after simulating EOQ and order quantity of OMMIP calculated in MIP model.
