Performance Comparing and Analysis for Slot Allocation Model

The purpose of this study is to ascertain the effect of weight setting of objectives on displacement and implementation difficulty in slot allocation model. Therefore, a linear integer programming model including three kinds of evaluation objectives with different weights is designed to compare and analyze displacement and implementation difficulty. Test results show that the difficulty of implementation can be significantly reduced to a certain extent by weight setting with a little increase of displacement under the condition of specific capacity setting. In addition, whether the movements are listed in order of descending priority or not has a great impact on displacement and implementation difficulty in the model. Capacity is surely a key factor affecting displacement and implementation difficulties. This study contributes to proposing an index of implementation difficulty for comparing and selecting suitable weights of evaluation objectives which can help decision makers to upgrade slot allocation policies.
