Abstract: Considering the complexity of carrier combat platforms and systems, and applying the parallel system theory to the operation, maintenance, combat and training of carriers, we propose the novel concept of parallel carriers, and define the digital quadruplet of parallel carriers: physical carrier, descriptive carrier, predictive carrier, and prescriptive carrier. In particular, we construct the intelligence framework of parallel carriers, including descriptive intelligence that turns physical carrier into descriptive carrier, predictive intelligence that turns descriptive carrier into predictive carrier, and prescriptive intelligence that turns predictive carrier into prescriptive carrier. Based on this framework, we further propose the idea of parallel command and control for parallel carriers, as well as the framework structure of parallel command and control systems, which help maintenance, formations, tactical groups, combat platforms, and other aspects to achieve transformation from traditional hierarchical command and control to parallel command and control.
