Research On Key Technologies Of Modular Configuration Design Of Logistics Equipment Oriented To Personalized Customization

As the mainstream production model in the 21 st century,mass customization provides customers with personalized customized products and services with large-scale production costs and efficiency.With the individualization and diversification of customer needs,the personalized configuration of logistics equipment products for customer needs has gradually become a key technology and an important part of the mass production of logistics enterprises.The modularized logistics equipment product configuration design can quickly realize the custom design of logistics products,the rational use and implementation of the modular configuration design of logistics preparation products,and provide effective guarantee for the development and design of logistics products for mass customization.The paper studies the modular product configuration technology of logistics equipment for individualized customization.Taking the single-column railroad track stacker as the research object,the model based on modular product configuration design is constructed.The article focuses on the division of product modules,evaluation of partitioning schemes,optimization of product multi-objective configuration and product modular configuration design based on PDM system.The specific research work of the thesis is as follows:(1)The first chapter introduces the research background and significance of the paper,and expounds the main content and research status of modular configuration design based on logistics equipment under personalized customization.and analyzes the existing research methods based on the key technologies of modular configuration design of logistics equipment products.And summarize them,and point out the existing problems and deficiencies.(2)The second chapter analyzes the modular design as the key technology and important implementation of mass customization,and proposes the module division of complex logistics equipment products based on hybrid fuzzy sets.The weight complex network is applied to the module division of complex logistics equipment products,and the component relationship network model of complex logistics product structure is constructed.The theory of fuzzy set is introduced to study the method of edge weight quantification of structure,function and strength of adaptability relationship of product parts.In order to reduce the subjectivity and ambiguity in the process of calculating the edge weight of the network model of the component relationship,the hybrid fuzzy multi-attribute decision-making theory is used to calculate the edge weight of the complex network.Finally,the Fast Unfolding algorithm is used to realize the module division of the weighted complex network of complex mechanical products parts,and the optimal scheme of module division is obtained.(3)The third chapter studies the evaluation of modularization schemes of complex logistics equipment products,and proposes a hybrid fuzzy multi-criteria group decision making method that considers customer demand preferences.The hybrid fuzzy set theory is introduced into multi-criteria group decision making to realize scoring and assigning of the evaluation criteria.The improved fuzzy analytic hierarchy process is used to obtain the initial state weights,and the adjustment of the standard weights is achieved by analyzing the customer demand preferences.The group aggregation method of fuzzy sets is used to realize the effective assembly of decision makers’ evaluation information.Finally,based on the technique for order preference by similarity to an ideal solution,the ordering and selection of module partitioning alternatives are realized.(4)The fourth chapter studies the key technologies based on modular configuration design of logistics equipment,including the modeling of logistics equipment product configuration and the solution and optimization of configuration model.Based on the process of modular configuration design of logistics equipment,the stacker is taken as the research object,and the comprehensive performance of the stacker product,the cost of the product and the product shipment period are taken as the targets of configuration optimization.The objective function for each target is established separately,and the constraints are determined to construct a modular configuration optimization model of the stacker product.Finally,the NSGA-II algorithm is used to solve the multi-objective configuration optimization of the stacker product,and the Pareto optimal solution set of the configuration scheme is obtained.According to the importance of the optimization goal,select the optimal solution set to suit your needs.(5)The fifth chapter studies the modular configuration design based on PDM system,combined with the existing Teamcenter system,realizes the modular configuration design of stacker products in PDM environment.Through the three steps of product configuration preparation,implementation and post-processing based on Teamcenter system,the stacker products can be quickly configured and designed.The product configuration design is mainly realized from the stacker product component relationship creation,component replacement and variable configuration,and finally generates a customer-satisfying configuration scheme.The configuration results such as the product configuration BOM table generated by the system configuration are sent to various departments of the enterprise for subsequent detailed design.
