When the inventory system accommodates more than one item under the effect of one or more constrained resources, the problem needs to some mathematical programs. The solution of these programs is more complicated and tedious specially when the number of items increased. Therefore, this analysis resorts to anew experimental model testing different feasible solutions searching for the best one . the problem formulation, which is mainly based on the economic order quantities (EOQ) model, is modified to ensure the minimum shift from the independent single-item order quantities and minimize the cost function of different models. Based on comprehensive equations and simple ratios, the solution procedure carries out the trade offs between all items in the system and exhibits the different alternatives if exist. no restrictions imposed on the number of items , the number / type of constraints, or the number of parameters in the system. thus making the developed heuristic simple and practical in solving large problems.
