This chapter presents the main contributions of this book which result in a distributed redundancy-orchestrated possibilistic information fusion system. The chapter is structured along the three main research topics of robust possibilistic fusion rules, distributed fusion topologies, and redundancy metrics. The chapter introduces the Dual Possibilistic Redundancy Metric (DPRM), which is particularly effective in cases of epistemic uncertainty and which forms the basis for redundancy-orchestrated fusion topologies. It also introduces two new possibilistic fusion rules for use within such topologies. These contributions result in the Redundancy-hardened Robust Fusion System (R2FS).
