This research proposed a formulation of piping and instruments arrangement problems and algorithms for solving it since there scarcely exists academic works in the research field.This result simplify the arrangement problems, and enables it to be solved automatically by means of applying existing algorithms for the pipe routing problems and arrangement problems of equipments. Instead of human's ambiguous evaluation of valve operability, a new method is proposed which calculates the valve operability costs making use of geometric features of the arrangement design. It enables us to optimize the arrangement design by computer calculation.
