초록

In this paper, we consider multi-module systems that consist of n modules in which k units work. The system are sold under warranty about system availability and if the system availability does not satisfy the announced value, the seller should pay some penalty and maintain properly the system to reduce the total maintenance cost. We assume exponential distribution to the failure times of the units and propose a Markov model to obtain the system availability. Some numerical examples are studied to check the effects of the model parameters to the system availability.
retirement age. In comparison to short-term investment management, lifetime financial planning must considerlife circumstances such as current age, retirement age, and lifestyle. One methodology for representing anindividual’s life stage is through human capital. This paper discusses human capital formulations and demonstratescalculations for various industries in Korea. Furthermore, the paper includes analysis on the effect ofhuman capital in lifetime financial planning as oppose to only focusing on financial capital when performingportfolio optimization.
