Developing a balanced strategy: A multi-objective model for emissions reduction and development of civil aviation in China

Due to the impact of COVID-19, China's civil airlines face an urgent imperative: to devise strategies that reconcile their development goals with the imperative of reducing emissions. Consequently, we have developed a multi-objective model that assesses the trade-offs between mitigation efforts and developmental pursuits. Furthermore, we have established future recovery and development scenarios for the post-epidemic era, with a specific focus on two major Chinese civil airlines selected for comprehensive case studies. Results show that: Our model can be used as a reference for airlines when deciding to introduce aircraft types and to purchase SAF fuel, and it can also offset the impact of rapidly rising airline costs due to fuel and aircraft type prices; In the scenario of considerable development of the operational level, the optimal investment strategy of the case companies would introduce mainly two types of aircraft, the A320NEO and the B737MAX8, which account for about 28.2 percent and 32.6 percent of the proportion of the types of aircraft introduced in the year. The results of the sensitivity analysis show that the main factor affecting the use of sustainable aviation fuel (SAF) by civil aviation enterprises is the SAF supply cap. Only when the supply ceiling is increased by 90 % does the SAF usage rate change significantly with the SAF price. Finally, policy proposals are made on the use of clean fuels, the introduction of aircraft types and the resumption of the development of aviation companies.

Comparative Analysis and Construction of Evaluation Indexes of Civil Aviation Service Quality

Scientific and effective evaluation of civil aviation service quality is of great significance to improve customer satisfaction and the main competitiveness of civil aviation enterprises. In combination with the core ideas of the service quality model, this paper compares and analyzes the service quality evaluation process of airports and airlines from the two dimensions of service contents and evaluation indexes on the basis of literature arrangement and summary. Based on the SERVQUAL model and the "China Civil Airport Service Quality Evaluation Index System", the related contents of the system is appropriately revised combined with the characteristics of airport and airline services. To this end, the service quality evaluation indexes of airports and airlines are respectively built. The research shows that there are indeed some differences in five dimensions of evaluation indexes between airports focusing on ground services and airlines responsible for in-flight services. Only when scientific and reasonable evaluation index system for the quality of civil aviation transportation services is established for evaluation in line with the characteristics of civil aviation transportation services in the two scenarios, can the overall service level of passenger transportation in civil aviation industry be upgraded to achieve the high-quality development of civil aviation transportation industry in China.

Statistical data on the Russian occupational injuries over two decades indicate a reduction in the victims annual number in all the sectors of the country economy from more than 150 thousand employees per year (2000) to 20 thousand (2021). It is shown that the number of fatal accidents during the same time decreased from 4.4 thousand per year to 1 thousand. The authors argue that during the aircraft ground maintenance in civil aviation, the cases of injury to employees and occupational diseases occur in accordance with what happens at the industrial enterprises. Statistics on monitoring working conditions and injury incidents at the aviation enterprises over the past three decades (excluding those injured in aviation accidents) are presented. Based on monitoring data, it is shown that in the period from 2000 to 2021, the rate of decline in the number of employees affected by industrial hazards in civil aviation is approximately 1.5 times higher than the same figure for the country. The results of a statistical analysis of the employee injury causes cases that occurred are described. It is stated that the working conditions characteristic feature of the employees at enterprises and organizations of the country during the period of time under consideration was and remains increased noise levels in the workplaces. At the civil aviation enterprises, the share of people employed in work with such harmful and (or) hazardous working conditions as noise, ultrasound, and infrasound the last decade is about 20 % over. The review is provided concerning the modern methods for reducing the impact of noise on the employees conducting aircraft ground handling operations. Recommendations are given on improving methods for counteracting the noise negative effects, developing personal protective equipment for areas of high noise pollution, and for further research.

A Comparative Study on Debt Risks of Chinese Civil Aviation Companies Under the Covid-19 Epidemic

As a highly indebted industry, the civil aviation transportation industry's debt risk management is crucial to its everyday operations. After the emergence of COVID-19 in early 2020, a number of airlines have been adversely affected by variables such as a reduction in the number of passengers, and their operating revenue has been severely impacted, with some even facing the possibility of insolvency. How to control the size and risk of debt is particularly crucial when income is low. On the basis of empirical analysis, this paper collects and sorts the financial data of three large state-owned civil aviation enterprises (China Southern Airlines, Air China, and China Eastern Airlines), selects several debt risk measurement indicators to analyse the impact of the epidemic on the debt risk of civil aviation enterprises, and offers corresponding recommendations for the management of airline debt risk.

АНАЛІЗ СИСТЕМИ УПРАВЛІННЯ РИЗИКАМИ АВІАКОМПАНІЇ

Risks are an integral part of any company. Not all types of risk can be identified, not all risk mitigation measures are cost-effective. Risk and the cost of avoiding it in aviation require rational decision-making mechanisms. There are many different risks in any airline as an aircraft operator, carrier and business entity. One of the main tasks of airlines is to minimize them. The article examines the risks that arise in the process of airlines and analyzes the risk management system in airlines. The impact of the pandemic on the aviation industry of Ukraine has been studied. The aviation industry both in Ukraine and in the world plays an important role, its importance in the world economy is constantly growing. This is facilitated by both technological development and the latest developments in the aviation industry, as well as globalization. However, at the same time, the number of risks is increasing, they are becoming more complex and diverse. Therefore, the task of risk management is relevant. Today, the risk management system of any airline is an urgent need, because the competitiveness and success of the airline is inextricably linked to risks. The activities of modern commercial enterprises, including civil aviation enterprises, are aimed at the formation of sustainable competitiveness and long-term survival. There are hundreds of airlines in the world, including 55 in Ukraine. Today, civil aviation in the world is in crisis. Ukrainian aviation is no exception. The closure of state borders and other measures taken in many countries to combat the spread of the coronavirus have led to a catastrophic reduction in air traffic. As a result, airlines were forced to reduce the frequency or cancel the vast majority of flights. All participants in the aviation market suffer from this situation. The development of a risk management system in the airline should be an integral part of its targeted management. The structure of risks faced by the airline is very complex and diverse. Risk is the residual probability of an event with significant consequences after considering mitigation measures.

Бізнес-план як елемент оцінки ефективності комерційного співробітництва авіакомпаній України в умовах глобалізації світової авіації

Based on the results of the world practice in the field of cooperation of civil aviation enterprises, the most promising methods of potentially ensuring the efficiency of operation are the merger or amalgamation of airlines in the form of an aviation alliance or aviation pool. The analysis of research on the application of aspects of business planning in the creation of an aviation pool or aviation alliance showed that, despite the need and demand of practice, this aspect in the theoretical, methodological and scientific direction is not given enough attention. An analysis of the literature showed that aspects of the use of the business plan as an element in determining the effectiveness of mergers of civil aviation enterprises in the context of European integration were not carried out. Referring to the above aspects, the ways of perspective development of Ukrainian airlines in the process of overcoming the conditions of competition and financial crisis by joining aviation alliances and creating pools are clarified. It was found that the main tool for determining the effectiveness of the reorganization of the airline and its financial recovery through cooperation is a business plan as a program of long-term development and assessment of economic feasibility. To achieve the goal of the study, the following tasks were performed: summarized and analyzed current areas of reorganization and financial recovery of Ukrainian airlines - the creation of aviation alliances and pools and opportunities for their development in modern conditions of the air transport market of Ukraine; the methodical approach to improvement of process of substantiation of reorganization and its economic results which is seen in development of the business plan of an estimation of commercial prospects is proved; developed recommendations for taking into account and reflecting in the business plan the features of the processes of creating an aviation alliance or pool. The prospect of further research, given the above, is to develop recommendations for management (management) of the process of reorganization of the airline in the implementation of the business plan to create an aviation alliance or pool.
