An indicator system is an effective way to monitor ongoing safety status. Current aviation safety measurements account for many qualitative technical and lagging indicators. Conversely, quantitative and leading indicators have only a tiny proportion. This research added more quantitative leading indicators and reviewed them to harmonize lagging and leading indicators to measure airport safety and provide an index. The South Korean national gate, Incheon International Airport's indicators, were applied as primary data to verify this research practically. Then, examples from International and national authorities were reviewed and extracted for use. Fifty-five safety specialists participated in the focus group discussion and three rounds of the Delphi survey. Finally, 51 sub-indicators were newly chosen. After this process, weights for each indicator could be assigned using the AHP (Analytical Hierarchy Process) to provide an integrated index. The result of the simulation with newly added indicators in the past five years (2020-2022) reliable trend showed in indicators and integrated index. Moreover, this allows monitoring the status of the details of indicators and holistic insight. This study considered that it is more suitable for a single company or service provider to use it according to the exact situation than in a macro- and general-purpose at the country or regional level.

Upselling is often a critical factor in revenue generation for businesses in the tourism and travel industry. Utilizing passenger data from a major international airline company, we develop the PAX (Passenger, Airline, eXternal) model to predict passengers that are most likely to accept an upgrade offer from economy to premium. Formulating the problem as an extremely unbalanced, cost-sensitive, supervised binary classification, we predict if a customer will take an upgrade offer. We use a feature vector created from the historical data of 3 million passenger records from 2017 to 2019, in which passengers received approximately 635,000 upgrade offers worth more than $422,000,000 U.S. dollars. The model has an F1-score of 0.75, outperforming the airline's current rule-based approach. Findings have several practical applications, including identifying promising customers for upselling and minimizing the number of indiscriminate emails sent to customers. Accurately identifying the few customers who will react positively to upgrade offers is of paramount importance given the airline 'industry's razor-thin margins. Research results have significant real-world impacts because there is the potential to improve targeted upselling to customers in the airline and related industries.

미국에서 자기비판적 분석의 법리에 의한 특권과 면제 이미 항공분야에서도 도입되고 있으나 일관성이 결여되어 있다. FDRs 프로그램은 FAA 또는 항공사에 의한 제제로 부터 공식적으로 보호되지는 아니한다. CVRs 프로그램의 경우 FAA는 집행조치를 위하여 그 데이터를 이용할 수 없으며 공개와 민사소송에서의 개시를 제한하고 있다. 따라서, CVRs은 FDR보다 높은 보호를 받고 있다. ASRS는 최초의 비자동적(non-self-disclosure) 보고시스템이며, 사고 또는 범죄에 관한 정보이외에는 FAA가 집행조치를 취할 수 없다. 다만, 비처벌 요건으로 규정하고 있는 "inadvertent and not deliberate)의 해석을 둘러싸고 FAA, NTSB 및 법원은 일관된 해석 기준이 없는 것으로 보이며, 데이터의 항공사의 징계조치에의 이용, 소송 당사자 또는 대중매체에의 공개 문제를 명확하게 다루고 있지 않다. 1990년대초 ASAP을 시범적으로 개시하였으며 FAA 집행조치 및 회사 징계조치로부터의 면제를 규정하고 있다. FOQA 프로그램은 1995년 시범프로그램을 통하여 최초로 시행되었으며 FAA 집행조치로 부터 면제되지만, 회사의 징계조치로부터의 면제에 대해서는 아무런 규정이 없다. 이러한 점은 ASAP와는 대비된다 할 수 있으며 노조협약에 의하여 FOQA 데이터에 근거한 회사의 징계조치를 배제시킬 수 있을 것이다. ASAP 및 FOQA의 데이터는 모두 2003년 FAA Order 8000.81에 의하여 공개되지 아니한다. 현재, ICAO의 움직임을 보더라도 국제사회에는 항공안전데이터를 보고한 자에 대한 보호의 강화에 대한 컨센서스가 형성되고 있으며 많은 국가들이 관련법을 시행하고 있다. 우리나라의 경우 현재, 항공법 제49조에 의하여 항공안전관리시스템을 도입하도록 되어 있다. 단계적으로 ASAP 또는 QOQA 등과 같은 프로그램의 입법화가 필요하다고 본다. 이와 더불어 미국에서와 같이 집행조치와 징계조치의 면제 규정 및 비공개 특권에 관하여 보다 구체적인 기준을 정하여 입법화하는 것도 필요할 것이다.

Purpose - This study was intended to provide implications for the importance of color to airlines where the image customers feel about the business is paramount. The importance of colors shown by the airline crew, an important human resource for airlines as contact workers, was investigated. We wanted to present suggestions by investigating and comparing the difference in customer attitude regarding the color of uniforms of the airline crew. Research design, data, and methodology - A survey was conducted to examine differences in perception of airline uniform color, with the research that suggests that the customer's attitude to uniform color will vary. The difference in the perception of passengers according to the colors of the airline uniforms was determined by conducting an empirical analysis. Results - Customers have a different attitude about the color of the uniform of airline's flight attendants' uniform. Full service airlines (FSC) generally have a bright, calm, neat, and heavy-handed feeling, while low-cost carriers (LCC) have a distinctive, dynamic, energetic, and cheerful feeling. Conclusions - An empirical analysis of the study found that customers' attitudes vary by uniform color for each airline. It has also been revealed that Airline's uniform color can communicate the company's goals it wants to convey.

Purpose This paper aims to improve management performance by effectively responding to production needs and reducing inventory through synchronizing production planning and procurement in the aviation industry. In this study, the differences in production planning and execution were first analyzed in terms of demand, supply, inventory, and process using the big data collected from a domestic aircraft manufacturers. This paper analyzed the problems in procurement and inventory management using legacy big data from ERP system in the company. Based on the analysis, we performed a simulation to derive an efficient procurement and inventory management plan. Through analysis and simulation of operational data, we were able to discover procurement and inventory policies to effectively respond to production needs. Design/methodology/approach This is an empirical study to analyze the cause of decrease in inventory turnover and increase in inventory cost due to dis-synchronize between production requirements and procurement. The actual operation data, a total of 21,306,611 transaction data which are 18 months data from January 2019 to June 2020, were extracted from the ERP system. All them are such as basic information on materials, material consumption and movement history, inventory/receipt/shipment status, and production orders. To perform data analysis, it went through three steps. At first, we identified the current states and problems of production process to grasp the situation of what happened, and secondly, analyzed the data to identify expected problems through cross-link analysis between transactions, and finally, defined what to do. Many analysis techniques such as correlation analysis, moving average analysis, and linear regression analysis were applied to predict the status of inventory. A simulation was performed to analyze the appropriate inventory level according to the control of fluctuations in the production planing. In the simulation, we tested four alternatives how to coordinate the synchronization between the procurement plan and the production plan. All the alternatives give us more plausible results than actual operation in the past. Findings Based on the big data extracted from the ERP system, the relationship between the level of delivery and the distribution of fluctuations was analyzed in terms of demand, supply, inventory, and process. As a result of analyzing the inventory turnover rate, the root cause of the inventory increase were identified. In addition, based on the data on delivery and receipt performance, it was possible to accurately analyze how much gap occurs between supply and demand, and to figure out how much this affects the inventory level. Moreover, we were able to obtain the more predictable and insightful results through simulation that organizational performance such as inventory cost and lead time can be improved by synchronizing the production planning and purchase procurement with supply and demand information. The results of big data analysis and simulation gave us more insights in production planning, procurement, and inventory management for smart manufacturing and performance improvement.
