Abstract

Assembly planning is commonly a tedious design procedure requiring a significant amount of manpower to obtain a feasible work plan. Poor assembly planning not only results in higher product cost and lower productivity but may also negatively impact the reliability, maintainability, and availability of a product during its life cycle. This study proposes a three-stage integrated approach with some heuristic working rules to assist the planner to develop a feasible assembly plan. In the first stage, Above Graph and transforming rules are used to create a correct Explosion Graph of the assembly models. In the second stage, a three-level relational model is developed to create a complete relational model graph and an incidence matrix. In the third stage, a genetic algorithm approach is used to generate and evaluate a near-optimal assembly sequence. An example of a military system is presented to demonstrate the feasibility of the proposed method.
