Maintenance is very important to\u00a0ensure\u00a0safety operations. The system is\u00a0close connected: physically and dimensional dependent. We define our system as a static inflexible system. One day of not operating costs the airport company 130.000$.\u00a0Therefore the maintenance interventions will take place at the same time, to keep intervention duration as low as possible.
\nAfter running our algorithm, we will find out the total amount of days the airport has close for maintenance work.<\/p>\n
For that we took four different system design under investigation and let them automatically find the lowest possible duration within their time range and maintenance duration.<\/p>\n
In our scenarios, the frames of the hangar can be built of timber or steel and the pavement of the runway with either Hot mixed asphalt or portland cement concrete.<\/p>\n
In the following, we are showing the advantages and disadvantages of the systems under\u00a0maintenance effort. The footages of the frames\u00a0are always the same but are from special concrete and need extra caring:<\/p>\n
Timber Frame<\/strong>\u00a0 \u00a0 \u00a0 \u00a0: Painting: every 10 – 25 yrs; replacement of single components: every 5 – 10 yrs;<\/p>\n Steel Frame\u00a0 \u00a0<\/strong> \u00a0 \u00a0 \u00a0 \u00a0: Painting:\u00a0 every 15 – 30 yrs;\u00a0replacement of single components: every 20 – 30 yrs;<\/p>\n PCC Runway\u00a0<\/strong> \u00a0 \u00a0 \u00a0 \u00a0: Joint sealing: every 12 – 20 yrs; Small repair: every 8 – 18 yrs<\/p>\n HMA Runway\u00a0<\/strong> \u00a0 \u00a0 \u00a0:\u00a0Joint sealing: every 8 – 16 yrs; Small repair: every 7 – 14 yrs<\/p>\n Bottom1 Footage\u00a0<\/strong> :\u00a0Cosmetic maintenance concrete bottom plate (EMC): every 5-10 yrs; Inspection measurement (IM): every 5 – 15 yrs; Concrete maintenance point foundation via injection (CMF): every 10 – 20 yrs; Replacement deck layer (RCBP): every 35 – 45 yrs; Replacement concrete foundation (RCF): every 45 – 55 yrs.<\/p>\n (The duration is roughly estimated by a third of its annual sequence in days)<\/p>\n The lifetime of the airport is 100 yrs.<\/p>\n 1. Scenario<\/strong><\/span><\/p>\n Timber Frame and PCC runway : 199 days closed for maintenance<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n 2. Scenario<\/span><\/strong><\/p>\n Timber Frame and HMA runway : 199 days closed for maintenance<\/p>\n 3. Scenario<\/strong><\/span><\/p>\n Steel Frame and HMA runway : 199 days closed for maintenance<\/p>\n 4. Scenario<\/span><\/strong><\/p>\n Steel Frame and PCC runway : 199 days closed for maintenance<\/p>\n <\/p>\n Conclusion: Every scenario shows a total time of duration for 199 days. This is owed by the many different inspection sequences and the long lifetime of the system. Also the duration is roughly estimated by taking a third of the sequencer number of the interventions. Civil engineering systems such as a wooden or steel frame, runway pavements and seatings from a hangar are designed for a very long lifetime.
