CPS-Based Smart Warehouse for Industry 4.0: A Survey of the Underlying Technologies

Abstract

This paper discusses how the state-of-the-art techniques in cyber-physical systems facilitate building smart warehouses to achieve the promising vision of industry 4.0. We focus on four significant issues when applying CPS techniques in smart warehouses. First, efficient CPS data collection: when limited communication bandwidth meets numerous CPS devices, we need to make more effort to study efficient wireless communication scheduling strategies. Second, accurate and robust localization: localization is the basis for many fundamental operations in smart warehouses, but still needs to be improved from various aspects like accuracy and robustness. Third, human activity recognition: human activity recognition can be applied in human-computer interaction for remote machine operations. Fourth, multi-robot collaboration: smart robots will take the place of humans to accomplish most tasks particularly in a harsh environment, and smart and fully-distributed robot collaborating algorithms should be investigated. Finally, we point out some challenging issues in the future CPS-based smart warehouse, which could open some new research directions.

Top-Down Human-Cyber-Physical Data Fusion Based on Reinforcement Learning

“…There was a self-organization of human in Cyber-Physical Systems. In [46] , human activity recognition was involved in CPS based smart warehouse for industry 4.0. Reference [47] designed ODIS (ontology-driven information system), which combined sensor data and natural language.…”

Cyber-Physical System Architecture for Minimizing the Possibility of Producing Bad Products in a Manufacturing System

“…The communication can use machine-machine (MM) protocols (e.g., MQTT protocol) and requires connections plug and play [7] and plug and produce that can be connected automatically. This level can use also other ways to identify people like what is proposed in [11] for human collaboration. The third level is created to generate virtual copies or cyber copies of the real physical systems.…”

Methodology Proposal for Storage Rationalization by Implementing Principles of Industry 4.0. in a Technology-Driven Warehouse

“…Based on the work by Heinrich [1], it is possible to list the main Methodology Proposal for Storage Rationalization T. Broum, M. Šimon by Implementing Principles of Industry 4.0 in a Technology -Driven Warehouse  mechanization of transportation at the end of the 19th century and beginning of the 20 th century (Logistics 1.0),  automation of the goods handling system in the 1960s (Logistics 2.0),  innovation in management systems logistics (Logistics 3.0) in the 1980s,  Internet of Things and Internet of Services (IoT, IoS) and Big Data that have implications for logistics (Logistics 4.0). Workforce savings and standardization of supply chain management are, according to [9], the main objectives of Logistics 4.0. Supply chain management can be defined as a large network where all parts of the supply chain are involved -from suppliers to end customers.…”

“…Let us consider Warehouse 4.0, part of the Logistics 4.0 and smart supply chain management in more detail. In [9], the smart warehouse is defined as 'an automated, unmanned, and paperless warehouse when conducting the operations of pickup, delivery, and bookkeeping'. Using intelligent management that is adopted and implemented correctly based on the Industry 4.0 principles, in combination with hardware and software technologies (hereinafter we will discuss concrete solutions) leads to changes in warehousing systems already in use.…”
