This article examines the pervasive issue of flight delays in Iranian airports and the factors affecting it. As air travel continues to play an important role in global connectivity and economic growth, understanding the causes and consequences of flight delays becomes critical. The importance of speed as the main indicator in the aviation industry compared to other means of transportation caused the issue of flight delays to be looked at more sensitively. Also, one of the influential factors for the performance of airline companies and the level of passenger satisfaction is the issue of flight delays and cancellations by the company. Using a comprehensive data set and statistical analyses, we examine the percentage of delayed flights in Iran's main airports and clarify the underlying factors affecting these delays. Then, using the defined index, we compare the performance of the most important Iranian airlines in terms of flight delays and cancellations in recent years using available data. As a result of these calculations, all domestic airlines in Iran, like other countries in the world, experience the most delays in the winter season. According to the evidence, this issue is predictable to a good extent and more efforts should be made in this field so that there is less impact on the economy of the country and the comfort of passengers during the trip

Reduction in project implementations is one of the most important challenges in construction management. In our country, after the revolution, there has been a significant leap forward in the construction of national civilization projects. However, despite the increase in the number of projects being implemented or commissioned, the problem facing these types of projects is the lack of start-ups and their operation on time according to the schedule. These delays also increase the cost of construction and reduce their quality. Comprehensive Quality Management (TQM) is the process by which management, with the participation of employees, customers and creditors, continuously improves quality. In other words, the final product in any industry must be tailored to the standards required by that industry to bring customer satisfaction. The construction industry is not an exception to this rule, and even the high cost of construction in this industry makes it necessary to ensure the control of the final product more than other industries. On the other hand, one of the goals and perspectives of TQM is to satisfy the customer completely with the least cost and attention to the optimal point of life cycle costs. In some cases, it increases so much that it takes the plan out of the being economic. In this article, while defining the basic topics of management, it deals with the role and position of time management, in the occurrence of delays and providing appropriate solutions to solve them. The aim of this study was to investigate the effect of quality management on optimal changes in construction costs for the construction projects.
