## 4 Conflict Resolution in the Actual Scheduling Process  
The initial step is the identification of the conflicts that have arisen in creating the scheduling process. Operational incompatibility happens when a new unplanned situation occurs. It is important to note that there are cases that are not generally considered to be conflicts but as individual multifunctional operations. Once the existing conflicts in the data set have been collected, the response is necessary to help decide which strategies should be used to resolve them. To proceed, the revision step is used to determine whether a modification of the conflicting activity is in effect. For each conflicting couple, if one of the activities was undertaken, other modification activities determine the type of resolution. If neither activity was carried out, modifications of both activities are monitored to determine the possible resolution. Finally, when both activities are resolved, the incompatibility is deleted from the list of identified conflicts. In addition,

The user may not enter a large number of possible activities that conflict with the planned activity into the scheduler because these activities will be rejected directly and never planned. For this reason, the elimination of conflicting activities is not considered to be an option in the decision making, but is the default choice when any resolution strategy fails. To create a _conflict resolution model_, the key attributes that should affect the conflict resolution process were first identified. The key attributes can be classified into the groups as follows [43]:  
* Driver-related characteristics, including driving behavior and personal temperament. Driver-related characteristics reflect the socio-economic orientation of the vehicle's driver, which is expected to affect cargo delivery needs and the ability to re-plan certain activities. * Performance-related characteristics. These include the trip duration, vehicle location, fuel consumption, the aim of the trip, and the constructed route information. Performance characteristics define activities and, in general, reflect the amount needed and the degree of flexibility. * Conflict-related characteristics. This group represents the type of conflict in which an overlap exists for the initially planned activity that is resolved by waiting until the activity is undertaken. It is considered that the symptoms listed above may have the greatest impact on driver expression behavior. The conflict-related characteristics determine the results of conflict resolution and priorities that are settled in repeating situations. The main descriptive statistics on conflicts and decisions are used in the model's construction. Compared to social and demographic variables, the signs of conflict play an important role in making decisions. When the number of overlapping initial activities increases, the number of deleted activities also increases and the number of modifications of activities decreases. However, the time available appears to have less impact on the decision selected. A small model reduces the likelihood of modification of the initial activity and increasingly deletes activities that appear to be in opposition. The specifics of the conflict activities were expected to have a significant impact on the resolution strategy chosen. In general, the original activity, which is characterized by greater flexibility, was likely to be only slightly more likely to be replaced. For example, original activities with more flexibility (leisure flexibility or driver personal flexibility only) have a higher modification percentage and a lower percentage of deletion. However, the results are not as clear as those in conflict activities.
