Abstract:
The efficiency/hard work of an employee in a graded manpower system can influence the grade to which he/she is promoted. The existence of double jump in a manpower system due to efficiency/hard work has been established and discussed in the context of the Markov model in a previous work. However, in manpower systems where the grade sizes are predetermined and the transitions into and within the system are to be predicted, the Markovian approach may not be the best approach. In the present study, we use the Renewal approach to discuss the double jump process due to efficiency/hard work in a manpower system and apply it to an insurance company. Theoretical results show that in such a system, the mean length of stay before promotion is exponential while the number of promotions before retirement is the sum of multinomial random variables.
Key Words: Double jump process, Efficiency, Manpower system, transitions, Renewal model
