Effect of understaffing and overstaffing constraints on recruitment and wastage manpower planning model

Abstract

The problem of overstaffing and understaffing is a key issue facing every business organization. This paper examined the effect of overstaffing and understaffing constraints on recruitment and wastage in a manpower planning model. Apart from the usual constraints of overstaffing and understaffing associated with the objective function of manpower planning models, we have incorporated two extra constraints. The two added constraints are (a) that the number of overstaffing employees be non-negative periodically, and (b) the organization started at full capacity at the initial period which makes the model different from existing models. It is observed that after the addition of n-extra nonnegative employee’s constraints in the proposed Dynamic Programming (DP) model, the number of wastage staff is equal to the number of staff recruited when the organization is operating at full capacity and that the model can be used to evaluate the inventory of the work-force periodically without waiting till the end of the total periods under consideration. Thus, our proposed model has advantage of sensitivity analysis compare to existing manpower planning models.
