DYNAMIC MODELING FOR AGE DISTRIBUTION AND AGE-BASED POLICIES IN MANPOWER-PLANNING

Modelling for age and retirement becomes essential in many situations where promotion is age based and retirement takes place on attaining a particular age. This paper presents a step-by-step approach to modell ing retirement and average age of population through system dynamics. The equations for a deterministic situation, with fixed residence time , are presented first, and then the equations are modified to accommod ate age distribution of individuals in the manpower pool. The proposed model has been tested for plausibility under various test conditions. The paper also discusses a few age-based policies. The model behavior with these policies is presented and discussed.
