The time required for airport process is considered more important as the airports are becoming bigger. International Civil Aviation Organization mattes this international standards and recommends not to exceed it. The passenger forecasting model is developed to predict the number of passengers at the check-in counter, and the area of formalities for departure and entry. In case of forecasting the number of outbound-passengers. the patterns of show-up lead time(SLT) at the check-in counter and lag time from check-in counter to the area of departure formalities are modeled in terms of time. On the other hand, the matter of the choice of check-in counters and areas of departure formalities are modeled in terms of space. In case of forecasting the number of inbound-passengers and transfer passengers, the time of airplane movement from arrival to block on at the gate and the time of passengers required from gate to the area of formalities for entry are modeled in terms of time. While the matter of the choice of gates and the areas of formalities for entry are modeled in terms of space. The average error of forecasting outbound-passengers and inbound-passengers is respectively 15% and 10%, which are considered excellent with the 5% error of passenger reservation information as input data. Through the development of passenger forecasting models, we assure we could provide passengers with valuable service because we allocate resource such as employees and equipments according to the degree of concentration of passengers.

Railway conflict detection and resolution problem (RCDRP) involves complicated field constraints that should be considered for practical service. In this paper, we address those constraints in brief. Particularly, following situations are addressed; (1) temporal change of network topology, (2) consideration of diverse conditions of track and train, for example, single/double tracks and passenger/freight service, (3) siding capacity limitation, (4) bidirectional sides used by both inbound and outbound trains, (5) regulation for passenger transfer service, (6) consideration of siding length, (7) Restriction on stopping before the track segment with steep slope.

This study analyzed empirically the effects of the perception of outbound passengers, who flew from Korea to overseas tourist destinations, on the cabin service quality, tourist experience, and tourist satisfaction. For empirical analysis, a survey was given to Korean passengers using a national carrier of South Korea. Based on empirical analysis, the researchers judged that the analysis results and implications could be applied to inbound foreign passengers who visited Korea for the tourism purposes if researchers generated significant results from empirical analysis. This paper designed a research model that represented the meaningful relationship among, airline cabin-service quality, tourist experience, and tourist satisfaction following preceding research. According to the analysis, that factors that consisted of the cabin service quality had a significant effect on the tourist satisfaction with a mediating effect of both the cognitive and emotional tourist experience. Therefore, the perception on airline's cabin service quality of the national carrier would be a starting point that can help improve the tourist satisfaction.

On-arrival duty free will prevent Korean outbound passengers from keeping the duty free items they purchased at the departure during their travel. Most Korean tourists have requested the airport authority to install on-arrival duty free since the grand-opening of Incheon int'l airport. Considering the fierce hub airport competition in the North East Asian region, the Korean government's decision to install on-arrival duty free is regarded as a well-timed intervention. The purpose of the research was to analyze sales correlation based on a comparison of sales of both departure and on-arrival duty free and to propose an administrative implication. Compared to business conglomerates running departure duty free, on-arrival duty free operators, who are small or medium companies, have weakness in product composition, marketing, and merchandising capabilities. According to the analysis, outbound passengers, who purchased fashion accessories and leather products at the departure duty free, tended to purchase cosmetics/perfume or liquor on the arrival duty free. Such complementary purchasing behavior of passengers showed there is barely a negative correlation between departure and on-arrival duty free.
