A cost planning method of manufacturing is vital for achievement of affordable composite design and production. Major two composite manufacturing processes, autoclave and RTM, were programmed on PC and cost modeling & simulation case studies were conducted with three composite aircraft parts which consist of flat panels and ribs. The keys for development of the methods are holistically discussed and proposed through the case studies : 1) precision of critical variables, 2) particular issues in composites and 3) goals as a planning tool.
