ABSTRACT Considering the shortcomings of current methods for real-time resolution of two-aircraft flight conflicts, a geometric optimal conflict resolution and recovery method based on the velocity obstacle method for two aircraft and a cooperative conflict resolution method for multiple aircraft are proposed. The conflict type was determined according to the relative position and velocity of the aircraft, and a corresponding conflict mitigation strategy was selected. A resolution manoeuvre and a recovery manoeuvre were performed. On the basis of a two-aircraft conflict resolution model, a multi-aircraft cooperative conflict resolution game was constructed to identify an optimal solution for maximising group welfare. The solution and recovery method is simple and effective, and no new flight conflicts are introduced during track recovery. For multi-aircraft conflict resolution, an equilibrium point that maximises the welfare function of the group was identified, and thus, an optimal strategy for multi-aircraft conflict resolution was obtained.

This chapter examines nonviolence as conflict resolution method in Kenya, and postulates that the advantages presented by nonviolence stand to help society overcome the trappings presented by violence. The author explores the idea of violence as laid out in the narrative and structure of the Kenyan society, the plausible reasons that gives rise to violence as a way of agitation for perceived rights and freedoms, and resolving conflicts.This chapter has focused on the history of Kenya with respect to the aspirations that existed during the time of clamor for independence and how the inability to make those dreams a reality curtailed the dreams, hopes, and aspirations of many who fought for independence and therefore creating a disenfranchised population, and above all, planting seeds of violence. This chapter observes that economic empowerment is a necessary tool to inculcate the theme of nonviolence in society. The author suggests using activities such as soccer and other related sports to create ambassadors and warriors for nonviolence.

This chapter introduces a collaborative conflict resolution model with a focus on cultural diversity and innovation. Its practices are research based, presented with explanatory theories, and uniquely suited to the multicultural teams of the global market. The chapter presents the optimal criteria for multicultural process identified in evaluative research conducted in four parts of the world: the Balkans, Cameroon, Nepal and Ukraine. It aims to demonstrate the correlations between collaborative conflict process at its best and innovation within diverse teams and organizations.
