Virtual aids to navigation
Published in Alexander Arnfinn Olsen, Core Principles of Maritime Navigation, 2023
The Vessel Tracking System (VTS), as the name suggests, is an electronic system that allows authorities to identify, track and monitor a ship’s position and course. There is a wide range of VTS available, though the most commonly used platform is GPS. GPS is a vessel tracking system works by transmitting signals from the target ship to high-orbit satellites. This means the system is highly effective and provides pinpoint accuracy. Although GPS is by far the most popular VTS, there are other VTS systems available including AIS, which we briefly discussed earlier. A vessel tracking system like AIS uses GPS technology to aid and serve as a transmission and receiving point using VHF radio channels. The AIS acts as a transceiver between the ship and the coastguard. There is also a vessel tracking system known as Ship Loc, which can be installed on board vessels and provides authentic readings pertaining to the location and position of the ship as well as ancillary information such as air pressure, wave pressure, wind direction and speed and a range of other useful data which are important for ship’s navigation.

Tracking systems add cost in terms of motor and controller maintenance, but this cost is relatively small compared with other cost savings that trackers provide. A single tracker motor, for example, controls more than 50 kWp of PV power generation, and requires only annual lubrication.

Vehicle tracking systems use GPS for locating the vehicles combined with software that collects fleet data for a comprehensive picture of vehicle locations, as shown in Figure 10.17. The vehicle locations can be accessed on a digital map or on specialized software.
Evaluation of project completion time prediction accuracy in a disrupted blockchain-enabled project-based supply chain
Published in International Journal of Systems Science: Operations & Logistics, 2023
The distinct nature of project-based supply chains lies in the project's unique nature as a temporary endeavour with a defined beginning and end in time with a defined scope and resource allocation (Project Management Institute, 2008). In a global supply chain, customers or sites in this context may be positioned far from suppliers who are more likely to change from one project to another. Projects require many shipments during different phases of their lifetime, making project deliveries more crucial due to the heavy penalties for late project completion (Helo & Shamsuzzoha, 2020). The decentralised structure of the global supply chain and the participation of many actors, each running their tracking system privately, make tracking and tracing goods along the supply chain a complex task despite the currently available technologies such as barcodes, Radio Frequency Identification (RFID), and Global Positioning Systems (GPS) tracking. This difficulty arises due to several issues. The first issue is the need for compiling tracking data from different sources. This issue escalates when packages change hands multiple times along their route, which is quite normal in international shipping. The second issue is the lack of third-party authentication for reporting tracking data. The third issue is that the decentralised structure makes the supply chain vulnerable to different risks and sensitive to disruptive events (Aydin et al., 2011). Therefore, prompt response and appropriate decision-making are crucial.
Robust capacity planning for sterilisation department of a hospital
Published in International Journal of Production Research, 2023
An SSD usually comprises three areas: contaminated, decontaminated and sterilisation. Once the kits arrive in the contaminated area, the technicians scan the barcode of the surgery kit into the online tracking system. Then, the surgery kit is checked for each item, and the items that require pre-washing are processed by technicians. Next, they are placed in washer-disinfector (WD) machines which apply several stages of disinfection. When a cycle of the WD machine is completed, the disinfected kits are unloaded from the other side of the machine which is also in the decontaminated area. This area has strict sterilisation rules with special air conditioning and staff clothing. The staff in the decontaminated area check the surgery kits and employ special tests to ensure that the decontamination is performed perfectly. Then they wrap the kits with a special folding technique (Superior Health Council of Belgium 2017) and textile that has indication labels on it which change colour during the sterilisation process. The wrapped kits are then placed within the steam sterilisation machines (autoclaves) that sterile the kits in high temperatures. After the sterilisation machine completes its cycle, the kits are left in a cooling area or sent straight away back to the surgical departments where the kits came from.

The FTI classified inventory management into four categories in incremental order, based on the complexity of ICT usage (IRDI, 2016). The lowest level is (IM1) tracking products by using a warehouse BIN card. It is followed by (IM2) monitoring the inventory almost daily and managing products based on customers’ monthly demand and (IM3) using warehouse management software such as MRP to track daily purchases and inventory turnover. The most complex level is (IM4) using Barcode or RFID as a real-time tracking system. In this paper, the definition from the IRDI (2016) was used to define the technological capabilities of a firm in the group of inventory management. H2: Investment of the main customers in ICTs significantly and positively affect the technological capability upgrading of a firm in inventory management.
