CoC： A Unified Distributed Ledger Based Supply Chain Management System

Modern supply chain is a complex system and plays an important role for different sectors under the globalization economic integration background. Supply chain management system is proposed to handle the increasing complexity and improve the efficiency of flows of goods. It is also useful to prevent potential frauds and guarantee trade compliance. Currently, most companies maintain their own IT systems for supply chain management. However, it is hard for these isolated systems to work together and provide a global view of the status of the highly distributed supply chain system. Using emerging decentralized ledger/bloekehain technology, which is a special type of distributed system in essence, to build supply chain management system is a promising direction to go. Decentralized ledger usually suffers from low performance and lack of capability to protect information stored on the ledger. To overcome these challenges, we propose CoC （supply chain on blockchain）, a novel supply chain management system based on a hybrid decentralized ledger with a novel two- step block construction mechanism. We also design an efficient storage scheme and information protection method that satisfy requirements of supply chain management. These techniques can also be applied to other decentralized ledger based applications with requirements similar to supply chain management.

Research on logistics management system based on supply chain management

Generally, supply chain logistics is the unification of logistics, information flow and capital flow, logistics runs through the whole process of the supply chain. Logistics connects the individual enterprise in the supply chain and it is the bond of mutual cooperation between enterprises. In that way, the logistics management becomes an important part of the supply chain management system naturally. However, it is not so long since the theory of supply chain management and logistics management put forward so they are still being refined. Besides, it is lack of green philosophy in the logistics management of the supply chain and effect of logistics on the environment and resource efficiency do not be considered synthetically. Yet, methods to solve the problem that customers return items and waste materials have been excluded from the enterprises and business strategy. With the awareness that people should protect the environment and conserve resources enhanced and governments increase the intensity of environmental regulations constraints, the theory and practice of green logistics management are valued by the foreign supply chain management and logistics management theory community and the business community gradually.

SUPPLY CHAIN DISRUPTION MANAGEMENT WITH MULTIPLE COMPETING RETAILERS

As for the supply chain consisting of a manufacturer and multiple competing retailers, the disruption management decision is considered for the demand disruption that both the investment sensitivity coefficient and the investment-elasticity are changed simultaneously. Meanwhile, the corresponding solutions are given for different cases of the disruption, and the characteristics of the solutions are analyzed. The production plan is proved to he robustness under certain conditions, and the production plan of the coordination strategy is investigated for the disruption with appropriate contractual arrangement, i. e. , a subside rate schedule. Mutual restraints exist between the changed investment sensitivity coefficient and the investment-elasticity when the coordination mecha- nism is used. And the more the number of the retailers in the system, the more the subside provided by the suppler on the coordinaton strategy.

Delivery Service Management System Using Google Maps for SMEs in Emerging Countries

This paper proposes a Delivery Service Management(DSM)system for Small and Medium Enterprises(SMEs)that own a delivery fleet of pickup trucks to manage Business-to-Business(B2B)delivery services.The proposed DSM system integrates four systems:Delivery Location Positioning(DLP),Delivery Route Planning(DRP),Arrival Time Prediction(ATP),and Communication and Data Sharing(CDS)systems.These systems are used to pinpoint the delivery locations of customers,plan the delivery route of each truck,predict arrival time(with an interval)at each delivery location,and communicate and share information among stakeholders,respectively.The DSM system deploys Google applications,a GPS tracking system,Google Map APIs,ATP algorithms(embedded in Excel Macros),Line,and Telegram as supporting tools.To improve the accuracy of the ATP system,three tech-niques are applied considering driver behaviors.The proposed DSM system has been implemented in a Thai SME.From the process perspective,the DSM system is a systematic procedure for end-to-end delivery services.It allows the interactions between planner-driver decisions and supporting tools.The supporting tools are simple,can be easily used with little training,and require low capital expenditure.The statistical analysis shows that the ATP algorithm with the three techniques provides high accuracy.Thus,the proposed DSM system is beneficial for practitioners to manage delivery services,especially for SMEs in emerging countries.

Supplier Selection Fuzzy Model in Supply Chain Management:Vietnamese Cafe Industry Case

Supplier selection is a vital part of the supply chain and is also a current issue that concerns businesses today as supplier quality directly affects the operations of the organization.Choosing the right supplier can help businesses increase productivity,competitiveness in the market,and profits without having to lower the quality of the products.However,choosing a supplier is not a simple matter,it requires businesses to consider many aspects about their suppliers.Therefore,the goal of this study is to propose an integrated model consisting of two models:Fuzzy Analytics Network Process(Fuzzy-ANP)model and Weighted Aggregated Sum Product Assessment(WASPAS)to solve the problem above.The Fuzzy-ANP model was developed to evaluate the weightings of the supplier selection criteria,and the WASPAS Model was used to rank the suppliers.An example of supplier selection in the coffee industry in Vietnam was studied to validate the model,namely 5 main criteria,with 16 sub-criteria,and 7 suppliers.The model test results show that the Fuzzy ANP and WASPAS integration model was suitable.In future,these developing models can apply to other industries or integrate with other models.

Issues on Supply Chain Management

Although supply chain is regarded as an integrated pr ocess, actually, researchers and practitioners have primarily investigated the v arious processes of the supply chain individually. The competitive field in most markets requires well-designed integrated supply chain instead of individual o perations. In this paper, some traditional thinking of supply chain is given fir st, then SCM (Supply Chain Management) is introduced, which views the entire sup ply chain as a whole rather than individual process and aims to increase transpa rency and alignment of the supply chain’s coordination and configuration, regar dless of functional or corporate boundaries. Secondly, issues regarding the significance and the situation of supply chain management in enterprises of Chin a are briefly described. In china, most enterprises haven’t established the ide a of supply chain management, supply chain are just focused on the step from sup pliers to manufacturers, which is a partial but not whole supply chain. Challeng ed by intense competition in the global market, further research on supply chain management is badly needed in China, if not, traditional pattern must be overwh elmed by world competition. Finally, suggestions for future research, especial ly the required conditions for a successful adoption of supply chain managemen t, are outlined. Organizations with Supply chain management can realize the advantages of backward vertical integration. However the following issues must b e paid attention to before supply chain management pattern is established.(1) Ch anging the corporate cultures of all members in the value chain to make it condu cive to supply chain management.(2) Developing long-term, cooperative and certi fied relationship with key suppliers.(3) Developing supply chain management soft ware that includes a completely integrated information system based on distr ibuted database throughout supply chain.(4) Reconstructing organization structur e adapting to supply chain management pattern.(5) Developing evaluation system f or performance measures of supply chain. In a word, supply chain management patt ern is necessary for domestic enterprises to win in intense world competition, w hile developing fitting pattern with key prerequisites is the most important.
