“…The implementation of VCo or IMDMM in practice is aligned with the field of robots. References like (Neil et al 2008;Foumani et al 2015Foumani et al , 2018Baniasadi et al 2020) are examples of similar studies in different environments. They all describe the same function studied in this research, IT tools, robots in this case, that help managers to face scheduling challenges, it means, once the sequence of the process to be conducted is well known (PO), software and robots together (VCo) perform all the tasks.…”

The paper presents an Integrated Maintenance Decision Making Model (IMDMM) concept for cranes under operation especially into the container type terminals. The target is to improve cranes operational efficiency through minimizing the risk of the Gantry Cranes Inefficiency (GCI) results based on the implementation of the Digital Twins concept for maintenance purposes. The proposed model makes a joint transportation process and crane maintenance scheduling, relevant to assure more robust performances in stochastic environments, as well as to assess and optimize performances at different levels, from components and transport device to production systems (container terminal). The crane operation risk is estimated with a sequential Markov chain Monte Carlo simulation model and the optimization model behind of IMDMM is supported through the Particle Swarm Optimization algorithms because the objective function a non-linear stochastics problem with bounded constrains. The developed model allows the container terminal operators (management process) to obtain a maintenance schedule that minimizes the GCI (holistic indicator), as well as establishing the desired level of risk. The paper demonstrates the effectiveness of the proposed maintenance decision making concept model for cranes under operation using data from of a real container terminal (case study).

“…UAVs are actually autonomous flying robots. The use of sensors is very common in autonomous robotics systems (like in robotic arms [69] or mobile robots [70]), and therefore equipping the UAVs with sensors is mandatory for the sake of positioning and collision/deadlock avoidance; combining different technologies also provides a certain redundancy in case one of the systems fails and it is a common practice, as in the aerospace world [71]. According to these ideas, and since RSS readings tend to suffer from discrepancy from the ideal model [72], a sonar sensor is added to help positioning.…”

Unmanned aerial vehicles (UAV) are spreading their usage in many areas, including last-mile distribution. In this research, a UAV is used for performing light parts delivery to workstation operators within a manufacturing plant, where GPS is no valid solution for indoor positioning. A generic localization solution is designed to provide navigation using RFID received signal strength measures and sonar values. A system on chip computer is onboarded with two missions: first, compute positioning and provide communication with backend software; second, provide an artificial vision system that cooperates with UAV’s navigation to perform landing procedures. An Industrial Internet of Things solution is defined for workstations to allow wireless mesh communication between the logistics vehicle and the backend software. Design is corroborated through experiments that validate planned solutions.

“…UAS have been introduced in global logistics systems to address some of these challenges, supporting warehouse, freight and logistics operations ( Baniasadi et al, 2020 ; Vamsi et al, 2020 ; Foumani et al, 2018 ; Zhang et al, 2018b ), providing real-time information on material and equipment condition and quality ( Azmat and Kummer, 2020 ). UAS have been deployed in Wal-Mart warehouses, and have cut inventory time from thirty days to just one, with costs, compared to a human employee, cut approximately in half ( Companik et al, 2018 ).…”

The scale and scope of global logistics systems make real-time visibility of individual assets in global logistics systems difficult. Aggregating global logistics data to a manageable level where interruptions and disruptions can be anticipated or resolved is high on the wish list of global logistics managers and decision makers. Asset tracking and condition visibility in global supply chains is also difficult because few standards or metrics have been assessed in a supply chain, particularly when new technology is introduced, such as unmanned aerial systems in global supply chains. In this paper, we describe the integration of an unmanned aerial system in a global logistics system, and the metrics used to assess the integrated system. We highlight the importance of supply chain process, business impact, societal and environmental sustainability metrics, in addition to economic and supply chain performance metrics, in evaluating the integrated system.
