A Conceptual Model for Blockchain-Based Agriculture Food Supply Chain System

Abstract

In agriculture supply chain management, traceability is a crucial aspect to ensure food safety for increasing customer loyalty and satisfaction. Lack of quality assurance in centralized data storage makes us move towards a new approach based on a decentralized system in which transparency and quality assurance is guaranteed throughout the supply chain from producer to consumer. The current supply chain model has some disadvantages like a communication gap between the entities of the supply chain and no information about the travel history and origin of the product. The use of technology improves the communication and relation between various farmers and stakeholders. Blockchain technology acquires transparency and traceability in the supply chain, provides transaction records traceability, and enhances security for the whole supply chain. In this paper, we present a blockchain-based, fully decentralized traceability model that ensures the integrity and transparency of the system. This new model eliminated most of the disadvantages of the traditional supply chain. For the coordination of all transactions in the supply chain, we proposed a decentralized supply chain model along with a smart contract.

Internet of Things-Based Fire Alarm Navigation System: A Fire-Rescue Department Perspective

“…Fire departments often arrive late at fire locations, which is a problem so far [6]. Two reasons can account for this.…”

“…e system is designed to notify and alert a remote fire station and user/owner when a fire accident occurs [23]. In recent years, the internet of things (IoT) has been applied in various fields, including smart agriculture, smart healthcare, and smart homes [3,6]. Several advantages of IoT can be found in home automation, including remote operation and maintenance, and autonomous interconnection of appliances [31].…”

“…In the following system, the communication is established using the GSM module; Arduino UNO acts as a microcontroller where the coding needs to be uploaded [5]. A SIM card is needed to operate this GSM module [6]. e fire station will receive notifications about the fire.…”

Modeling the Sustainable Supply Chain Network Design for Food-Agricultural Industries considering Social and Environmental Impacts

“…( 9) Since the main model in this research is researchercentered and specific, it can be used to determine the most influential factors and relationships between them, as well as to determine the independent factors of factor analysis or interpretive structuring method in future research. (10) In this research, the DEMATEL technique has been used to analyze the data. Other research can use other techniques or a combination of these for this purpose.…”

“…Environmental cleanliness and pollution prevention are important issues. Furthermore, sustainable development of food-agricultural industries can be achieved only by examining and solving the problems of natural resources and environmental management with the help of economic policies [ 10 ].…”
