abstract

The traditional supply chains faces several challenges such as uncertainty, cost, complexity and vulnerable problems. To overcome these problems the supply chains must be more smarter. For establishing a largescale of smart infrastructure to merge data, information, products, physical objects and all processes of supply chain, we applies the internet of things (IOT) in supply chain management (SCM) through building a smart and secure system of SCM. We have prepared a website for suppliers and managers. We tracked the flow of products at each stage in supply chain management through the Radio Frequency Identification (RFID) technology. Each product attached with RFID tag and scanned through RFID reader and ESP8266 at each phase of supply chain management. After scanning the tag we stores tag id in the database. All information about products will be entered by suppliers and then uploaded to managers. In our system the supplier and manager gets perfect information of the entire life cycle of goods, and this will achieve transparency of supply chain management. For assessing security criteria of proposed system of supply chain management, we also proposed a framework which integrates neutrosophic Decision Making Trial and Evaluation Laboratory (N-DEMATEL) technique with analytic hierarchy process (AHP). The neutrosophic Decision Making Trial and Evaluation Laboratory (N-DEMATEL) technique is utilized to infer cause and effect interrelationships among criteria of smart supply chain security requirements. Depending on obtained information from (N-DEMATEL) the neutrosophic AHP is utilized to calculate weight of criteria and sub-criteria. Then the integrated framework will help researchers and practitioners to design secure system of supply chains. We presented DEMATEL and AHP in neutrosophic environment to deal effectively with vague, uncertain and incomplete information. So the proposed system of supply chain management will be able to overcome all challenges of traditional SCM and provide secure environment of SCM processes.

 Conclusions and future directions

In this research we presented a framework for supply chain management which based on IOT technologies. The proposed system automates identification process of products, trace and track products globally, achieves transparency, reduce time and cost, and then will achieve customer satisfaction. The designed website between company managers also enhances coordination process, makes suppliers able to find selling information of their products easily through entering system with their username and password. Our website remove middlemen via direct communication between suppliers and managers via system, and then it increase profit for both manager and supplier. In order to assess security framework for our proposed framework of smart supply chain, we integrated neutrosophic DEMATEL with neutrosophic AHP. The reason for integrating two techniques by using neutrosophic theory returns to the advantages of neutrosophic theory in handling vague, uncertain, inconsistent and incomplete information which exist in real life judgments. So neutrosophic set theory here is better than crisp set theory and fuzzy set theory. Since it considers truth degree, indeterminacy degree and falsity degree for each judgment, but crisp and fuzzy set theories does not.
