The Study of Time Computation of Yang-Feng Network

Based on Yang-Feng network that can be used to describe concurrent processes, the authors define and construct a new kind of network which can be used to denote and calculate process time adaptive to the specifics of concurrent processes based on the optimization theory of network as well as individual studies. Two computing methods of process time with different codings of the net nodes are presented. The computing methods can be widely used in concurrent designs and other related research fields within concurrent engineering.
