In this paper we portray current approaches to the development of system dynamics models. Like black holes themselves, binary black holes are often divided into stellar binary black holes, formed either as remnants of high-mass binary star systems or by dynamic processes and mutual capture; and binary supermassive black holes, believed to be a result of galactic mergers. System Dynamics. Typically provides more reliable forecasts of complex systems than statistical models, and therefore leads to better decisions. Lewlyn Rodrigues. A system dynamics approach is a simulation method in solving real-world problems to describe relationships among variables in complex real systems.
