Abstract: As the design of complex engineering system is a decision-making process of multi-disciplinary synthesis design optimization,a System of Multi-disciplinary Flow Integration and Design of Experiment based on component is designed and implemented．The system supports the conceptual design and simulation experiment of complex engineering system．Compared to current multi-disciplinary design optimization systems,the system has the following characteristics and advantages:1) Design of experiment (DOE) and flow’s hybrid model other than project management style is proposed to easily manage the model；2) Multi-threading technology is adopted to seek the parallel scheduling execution for flow’s components and DOE’s instances；3) Dynamic task scheduling technology is proposed to realize the flexible control mode of the combination of DOE’s automatic scheduling and interactive control.

Key words: Multi-disciplinary flow integration,Design of experiment,Parallel scheduling
