Analysis of Activity Conflict Resolution Strategies

This paper attempts to model the process or activity scheduling conflict resolution with actual scheduling process data. The resolution or activity scheduling conflicts is a critical component or rule-based activity scheduling models. Many current scheduling models use an assumed priority for each activity type to estimate how activity conflicts will be resolved, but research has shown that these activity type-based priority assumptions often do not hold in actuality. Therefore, the conflict resolution data captured in the scheduling process survey were used to estimate and evaluate a number of conflict resolution models, including a decision tree model and two discrete choice models. Both the conflict resolution decision tree model and the discrete choice models showed a promising ability to predict the resolution strategies chosen almost entirely on the basis of the attributes of the activities in conflict and characteristics of the surrounding schedule. These models present a useful advance in increasing the realism and accuracy of rule-based activity scheduling models.
