The purpose of this studγ if to understand problem of present bus scheduling system and to develop optimal bus scheduling model which improve bus passenger's degree of satisfaction(DOS) and bus company's operation efficiency at the same time. This study developed optimal bus scheduling model, which reflected bus passenger's degree of satisfaction(DOS), applied to existing model that summery of bus operation cost($C_o$), passenger queuing time cost($C_{pw}$) and passenger travel time cost($C_{pl}$). And optimal bus scheduling model which developed in this study is optimized that using LINGO program based on linear program. Also by using the general case in Busan, compare total cost of present bus scheduling system and existing scheduling model with total cost of optimal bus scheduling model which reflected bus passenger's degree of satisfaction(DOS).

In this study, specific review for the recent trend both in technical parts and the contents of IFE will be revealed. At the same time, how the passenger's satisfaction on IFE will lead to make an intention of repurchase and create the transmission of positive feed backs on the concerned airline has been thoroughly studied. In order to do the above, 250 air traveling passengers has participated the survey and 235 survey forms has been analyzed by Multiple Regression Analysis. According to the analysis, the physical environmental Improvement in aircraft system helps to Increase the satisfaction degree on IFE. The convenience is revealed as the most effective factor in the satisfaction degree on IFE while the atmosphere and design is regarded as the similarly Important factor. The contents of IFE are obviously affecting the satisfaction degree in positive side. Consequently, the customers' satisfaction on IFE positively affects to the repurchase intention especially to the transmission of the feed back.
