Online and Offline Collaborative Omnichannel Retail Supply Chain System Robust Control and Optimization
Technological innovation and consumption upgrades have accelerated the rapid development of the"new retail"omnichannel model.With the implementation of this model,a large number of enterprises blindly added new online channels and excessively imitate business model,resulting inoffline mismanagement,overstocked inventory,and high online return rate.Therefore,how to integrate the advantages of offline and online channel,expand the integrated and intelligent omnichannel layout,and meet the personalized and seam-less interactive experience of consumers has become a difficult problem that needs to be solved urgently by the industry and academia.Focusing on these questions,ROPS(Reserve-Online-Pick-up-and-pay-in-Store)and BORP(Buy-Online-and-Pick-up-in-Store)strategies are integrated to build a state feedback control model for the omnichannel retail supply chain system,and four strategy models are compared:N-BR(do not adopt BORP and ROPS),Y-B(adopt pure BORP),Y-R(adopt pure ROPS),Y-BR(integrate BORP and ROPS).Further,the influence of consumer channel preferences,cross-channel delivery and return parameter uncertainty on supply chain system inventory,production/ordering and profit is investigated,and the bullwhip effect suppression method is studied based on Lyapunov stability theory and linear matrix inequality algorithms.The results show that:(1)Omnichannel retail companies should regard consumer channel preferences as their characteristics,and balance the profits of manufacturers and retailers;(2)Y-BR strategy will cause a certain risk of out of stock and retailers should rationally design specific configuration conditions for adopting BORP and ROPS to increase profit;(3)Retailer's profit depends on the pick-up rate.If the offline pick-up rate is too high,it will cause a serious loss in the retailer's profit;(4)Robust optimization control effectively suppresses the bullwhip effect.This research improves the operating efficiency and profits of new retail enterprises,increases the core competitiveness of physical retail stores,and provides a certain theoretical basis and practical value for the transformation and development of omnichannel retail enterprises.
