| Author | Chaug-Ing Hsu, Ching-Cheng Chao |
| Summary | In this study we formulated a dynamic programming model to determine the optimal facility purchase and replacement scheduling by considering facility renewal costs, aviation safety, passenger service level, and airport finance. Then, we constructed various cost functions on facility depreciation, operation, maintenance and delay for different facilities at different time stages. Time-dependent passenger volume, reliability, and utilization are considered to reflect variation in those costs due to time accumulation. Moreover, this study uses CKS International Airport as an example to demonstrate the application of the model. The results show that maintenance cost for mechanical equipment increases in a higher rate than that for electronic equipments as equipment reliability decreases. Besides, equipments of longer operating time also incur higher delay costs than those of shorter operating time, as equipment reliability lowers. The optimal service life of check-in and immigration counters are shown to be 9 and 8 years, respectively, for the same passenger flows. This study provides the airport authority with the optimal strategic decisions on the purchase and replacement of various facilities in terms of quantities and timing. |
