摘 要：The profitability of a supply chain(SC)is proportional to the stability of all its stakeholders as well as their consistent information sharing with an effective and efficient communication *** inefficiencies,such as the bullwhip effect(BWE)and product unavailability,may be caused by a lack of coordination in an *** importance of sharing consumer demand has been quantified by comprehensive studies under the assumption that all SC participants will access the same ***,only a few studies have studied the effect of minimal coordination or limited visibility of information while considering their effect on the overall efficiency of an *** work primarily leverages blockchain technology(BCT)to create a simulation *** do this,an SC BWE-based model is initially *** that,a blockchain-based robust information sharing system is ***,information sharing is challenging,and SC stakeholders may not really trust each other and hence be reluctant to share sensitive *** that,this paper propose an improved proof-ofauthority(PoA)consensus algorithm that will increase trust in a decentralized SC *** experiments are carried out to demonstrate the effectiveness of our approach,and the simulation results clearly demonstrate the effectiveness of information sharing in a supply chain via blockchain,as well as that trust between partners tends to increase overall SC efficiency and reduce BWE.
