The efficiency of a transportation system is generally measured in terms of its ability to efficiently process the unit and the displaced element. The performance of any system depends on the performance of its components, and an evaluation of each of these components is necessary to determine the overall capabilities of the system. The evaluation of the components of a system is measured by determining and examining its capacity. The runway and apron are important components of the airport system, the exact capacity of which is important and significant. In this article, the runway and apron capacity of Imam Khomeini Airport in 1397 (base year) has been calculated and evaluated and evaluated for the project year (opening of the second runway terminal and terminal No. 2 of the airport) for two scenarios with and without night stop. The results show that the runway capacity is only for the landing operation of 34 aircraft per hour, only the take-off operation of 41 aircraft per hour and for the combined operation of 56 aircraft per hour. The capacity of the apron is 62 places in the base year with the night stop scenario and 28 places for the non-stop night scenario, which are 81 places for the horizon year and 57 places for the night and no night scenarios, respectively.

The main purpose of this study is an analytical comparison of attitude change to integrated management of urban water/wastewater in the development plans of Iran, before and after the Islamic Revolution. The results indicate that there are four periods of changes in attitude towards this issue in Iran. The first period was initiated to launch planning thinking. In the second period, which lasted till before the Islamic Revolution, the planning system in Iran, after gaining experience, has undergone a dramatic change and some issues such as national coverage of the wastewater collection system, reliable water supply and minimum price of water, were mentioned in the development plans for the first time. In the end years of this period, planning in Iran was matured and all aspects of integrated management except water treatment had been considered. The third period came simultaneously with the revision of the constitution of Iran, after the revolution. In this period, supported by macro policies after the mid-2000s, a period of excellence in the approach of integrated management of urban water and wastewater was created. Also, a macro roadmap in the planning system of Iran was developed. The fourth period of attitude changes began with the beginning of the second step of the revolution and will last until 2065. In this period, the "Islamic-Iranian Model of Progress", as an upstream framework of the macro policies and development plans, have a significant role in establishing an integrated urban water and wastewater management approach in future development plans.
