SENSITIVITY ANALYSIS OF EOQ MODEL

Sensitivity Analysis is regarded with the manner in which those results of solutions change in response to change in model parameters.

It is important to appreciate that in formulating our inventory models, we have really been performing a planning exercise. Thus we have made certain assumptions and estimates (e.g. annual demand D, holding costs H, & ordering costs O) and out solutions have obviously been affected by these. When for example calculating a deterministic EOQ value with maximization of total inventory costs as the objective, expected annual demand (D) is taken into account. If we subsequently find that annual demand has differed from that expected then we will find that the EOQ we selected was not the optimum and, as an outcome, the total inventory cost was not really minimum.
