Location estimation for waypoint-based autonomous driving robots primarily relies on SLAM (Simultaneous Localization and Mapping) and GNSS (Global Navigation Satellite system) technologies. GNSS performs well in open areas but struggles with signal issues, while SLAM offers high accuracy in feature-rich environments but faces challenges in open spaces. This study integrates SLAM and GNSS, enabling seamless switching between systems when one encounters difficulties. The combined system ensures consistency by aligning coordinate systems and directional data. Experiments in indoor, forest, and open environments demonstrate that the switching algorithm enables stable autonomous driving in diverse conditions, effectively leveraging the strengths of both systems. © ICROS 2025.

IT/OT convergence in the form of a Cyber-Physical system (CPS) presents an opportunity to apply recent Information Technology (IT) advancements to Operational Technology (OT). The IT/OT convergence introduces cyber security threats for OT. The OT communication protocols, for example, have limited or no security capabilities for securing data exchange beyond basic authentication. The RNG (Random Number Generator) function is crucial in PLC for producing the encryption keys or the initial seed for security algorithms. The software-based PRNG (Pseudo RNG) is the most common approach for RNG in OT, instead of hardware-based RNG. This study provides a systematic literature review of the most recent evidence in digital transformation to secure data exchange in smart factories, within OT, or across OT and IT settings. It does this by looking at the PRNG on PLC and identifying the most recent trends and best practices. The findings include up-to-date data on author countries' distribution, published journals, research trends, industries, and industry types. The findings also address whether data flow is encrypted or shared in plaintext to ensure secure data transfer between IT and legacy OT environments. This paper concludes that while there is known RNG implementation in the actual embedded system in ICS, there is no evidence in the literature for using RNG in ICS networks for PLC implementation to secure data transfer with encryption. © 2024 IEEE.

The airline industry is a highly regulated industry where every aspect of operation requires adherence to regulations and policies mandated by the government. Safety is the core value-offering of fast and reliable air services, and this is achieved in part by the robust training requirement for pilots. Pilot training and qualifications are achieved with the use of full flight simulators. The significant costs involved in the use of the simulator, other additional costs involved, and the need to minimize pilots' time away from flight duties while undergoing training, require an effective selection process to decide on the most beneficial training venue. Not much research has been done on this topic area and the research gap necessitates a study of this nature. The goal is to provide a criteria analysis to support the simulator training venue decision process with the use of analytic hierarchy process (AHP). The analysis resulted to a selection among the alternatives that provide the best training venue for pilot training based on the evaluated criteria. It proved the applicability of the AHP when deciding on available alternatives based on set criteria. This study will contribute to the management of training requirements conducted by airlinetraining organizations and help their heads/managers/decision-makers in utilizing decision-making tools and processes when choosing the best alternative among available training resources. © 2023 ACM.

The contract terminations for the provision of maintenance services to the tenants of the managed mall affected our organization's planning, strategy, operations, and revenue. Being able to predict the contract renewals, prevention and readiness plans can be made. Using the data from the computer-aided facilities management (CAFM) software and the available research papers about customer behaviors;the contract renewal outcomes were predicted. In this paper, the operations data of 47 mall tenants (customers) that operates different types of retails were utilized. The data by performance, satisfaction, asset condition and relationship based on the review of the previous studies were categorized. Binary logistic regression was utilized to test the data. The results showed that communication was the strongest influencer to the customers' behaviors in service contract renewals more than price, satisfaction, and experience. When we understood how to interpret and use the data from the internet of things (IoT), it helped suppliers not only to predict the renewal outcomes, but also build a strategic customer retention program by using the significant variables identified. © 2023 IEEE.

Forest fires have a significant impact on ecosystems and human life, especially in northern Thailand, where Chiang Mai is severely affected. Traditional methods for detecting forest fires have limitations, so there is a need for advanced simulation models. This research uses Agent-Based Modeling (ABM) to develop a forest fire simulation for Chiang Mai. The methodology involves collecting historical data, performing Multiple Regression Analysis, designing the simulation, and testing it. Data from 1998 to 2021, including temperature, relative humidity, wind speed/direction, burn area, and slope, were collected from various sources. Multiple regression analysis identified wind speed as the most significant factor affecting burn area. The forest fire simulation, designed using ZF Wang's spread model and tested with AnyLogic, showed that wind direction and speed are crucial in fire spread. The simulation accurately predicted high-risk areas, helping in proactive planning and response. This study confirms that wind is a critical factor in forest fire spread, providing a valuable tool for fire districts to improve preparedness and management. Future research should focus on refining the model with localized data and integrating real-time detection to improve its accuracy and applicability. © 2024 IEEE.
