Precast concrete technology is being actively investigated once again by domestic construction conglomerates and precast concrete production companies as a solution to labor supply problem due to labor cost increase and shortening of high-rise building construction time. Especially, the production scheduling of precast concrete members is an important management step directly affecting the economics of the technology and the construction schedule at the construction site. Nonetheless, there is no manual or a program of standardized process, to which a production manager can conveniently refer up until now, in the establishment of a production scheduling of precast concrete members. This causes inefficiency of its production schedule. Thus, this study aimed at developing the process and system, which can conveniently establish the production schedule for precast concrete members for the production companies, after the determination of the assembly schedule of the member at the construction site. The result of this study will contribute to satisfy the deadline for the production of the member for its production companies. And it is believed to be used as an efficient decision making system in the establishment of a production schedule of precast concrete members to promote the efficiency of the mold usage plan. Further, it is expected to be used as a guideline for the production manager to establish the production schedule of precast concrete members.
