An Analytical Model for Company Manpower Planning

We develop a model for a manpower hierarchy by expressing algebraically the relationships between its size, its age distribution, the wastage rates, the age distribution of the recruits and the proportion in the different grades for each age. Each of these factors is defined both in the present and in the future. By making a simplifying assumption, we are able to reduce the number of variables in the problem to a manageable number, and can use the model to explore the possible futures for the manpower system and to examine the effects of possible decisions regarding recruitment, retirement and promotion.
