Optimal design for scale-based product family based on multi-objective firefly algorithm

Aiming at the complexity of rational balance between product family's commonality and difference without transcendental information,a multi-objective constraints optimization model of scale-based product family with commonality maximization and average performance lose minimization was proposed under multi-platform design of scale-based product family.Based on the ideas of non-dominated sort and crowding distance sort,the compare operation and the update operation of traditional firefly brightness were improved,and a modified firefly algorithm adapt to solve multi-objective constraint optimization problem was presented.To solve the optimization model of scale-based product family,a expression pattern of two-layer artificial firefly structure with common variable ability was constructed.A simulation study on optimization design of motor product family was provided to evaluate the effectiveness of proposed model and algorithm.
