The paper presents a new approach to development integrated mathematical model for composite pressure vessels (CPVs) based on concurrent engineering (CE). Important parameters of CPVs in both design and production phases were considered simultaneously within a unified information space. On that basis, mathematical model of CPV was built with 9 design variables, 14 functional constraints and 3 performance criteria. Then, the genetic algorithm (GA) was applied for that model and a set of 75 Pareto optimal solutions was found. Based on these solutions, an appropriate design was chosen for the next manufacturing phase.
