Abstract: An interface matrix based on coarse programming and Design Structure Matrix (DSM) based on fine programming, integrated two phases programming framework, is put forward. Interface matrix based on coarse programming defines an interface matrix according to the interface relation of parts, and then transforms interface matrix based on the rule of interface number first, so as to aggregate interacted parts together. DSM based on fine programming transforms interacted interface matrix into DSM according to the time constraint of tasks, and then partitions DSM, so as to decompose task group into independent tasks, decoupled tasks and coupling tasks. Simulation and case study indicate that when the density of unclear interfaces is low, such a programming method can lessen the size of part group evidently.
