Dynamic analysis of the population composition of Iran's police force using systems dynamic methodology

Demographic composition of staff in varying degrees has an important role in process of organizational growth, jobs and resources allocation in management of police human resources. Composition of demographic of police must be in accordance with approved current jobs and organizational positions. Police demographic composition works as a chain of degrees which all its members must grow in accordance with their defined jobs. Due to the influence of each component to the next one in the continuum of demographic composition, policies and decisions that can fulfill its appropriate and balancing growth will be very important. This study aims to analyze the structure of the dynamic behavior of the demographic composition of police using a holistic and dynamic approach. In this study, dynamic model of police demographic composition delivered based on methodology of system’s dynamics, so that the dynamic hypothesis of the study was shaped based on some data gathered through the investigating of the documents, library studies and researcher-made questionnaire under the supervision of the organizational experts. Researchers try to analyze the current reactions impacts in structure on demographic composition’s behavior. In this approach, after exploring the reactions and representation of the defining structure of the behavior, implementation of the different policies of decision simulated. 20 participants were selected from among professors in universities, experts and senior managers who were familiar with the concepts of human resource management in Naja through the non-purposeful sampling method. Findings reveal the reference and dynamic model for demographic composition structure as the most important achievement of the research. Moreover, variables and leverage points of the defined model and its different scenarios and policies, were implemented and its results were simulated. It is concluded that the duration of the personnel’s stop in any degrees is the most dynamic factor in the composition of demographic
