In view of the dynamic change of customer requirements (CRs) during the process of product use, in this paper we propose a Bayesian Nash equilibrium configuration model for product variant design driven by CRs. By analyzing CRs, the complete variant requirements of the products can be obtained. Combined with modularization and parameterization variant design methods, a parametric variant instance is proposed. Since cost and delivery time are affected by the product variant design, firms and customers are established as two decision-making bodies, and Bayesian Nash theory is introduced to the product configuration. The theory takes the product cost and customer satisfaction as the payoff function of the game, and based on the threshold value search of the customer satisfaction it determines the strategy set of the two parties. The Nash equilibrium solution equation is established and solved by a simulated annealing algorithm. The optimal product configuration scheme satisfying the interests of both sides of the game is obtained. Finally, the automatic guided vehicle (AGV) is taken as an example to illustrate the effectiveness and practicability of the method.
Both industry and science point out the need to integrate PLM and ALM since products evolve from mechatronic to smart products. This paper investigates data management tasks fulfilled when creating or improving design. Particularly, the differences and commonalities in design evolution management of the software and hardware disciplines are considered.This paper introduces a beta version of a hash function based tool, applying the software management mechanism on mechanical revision management.
Currently systems grow in complexity and more aspects, such as socio-technical aspects or the obligation to produce proof become more important. Both require a safety analysis on the system level early in the design process. System overview is provided by MBSE, while safety analysis is provided for example by FMEA. Both processes are executed organizationally and timely separated from each other. This research proposes a concept and a tool integration at the concept design phase, during system definition and functional decomposition and evaluates the effect and its potential applicability.
