In recent years, the adoption of truck–drone collaborative delivery has emerged as an innovative approach to enhance transportation efficiency and minimize depletion human resources. Such a model simultaneously addresses endurance limitations drones time wastage incurred during “last-mile” deliveries by trucks. Trucks serve not only carrier platform for but also storage hubs energy sources these unmanned aerial vehicles. Drawing from distinctive attributes delivery, this research created...

In many service delivery systems, the quantity of available resources is often a decisive factor quality. Resources can be personnel, offices, devices, supplies, and so on, depending on nature services system provides. Although computing has been an active research topic for decades, general approaches that assess impact resource provisioning quality matrices in rigorous way remain to seen. Petri nets have popular formalism modeling systems exhibiting behaviors competition concurrency almost...

Utilizing drones for delivery is an effective approach to enhancing efficiency and lowering expenses. However, overcome the range payload capacity limitations of drones, combination trucks gaining more attention. By using as a flight platform supporting their take-off landing, can be greatly extended. This research focused on mixed truck-drone utilized reinforcement learning real road networks address its optimal scheduling issue. Furthermore, state behavior vehicle were optimized reduce...

Forest fires pose severe challenges to forest management because of their unpredictability, extensive harm, broad impact, and rescue complexities. Early smoke detection is pivotal for prompt intervention damage mitigation. Combining deep learning techniques with UAV imagery holds potential in advancing fire recognition. However, issues arise when using UAV-derived images, especially detecting miniature patches, complicating effective feature discernment. Common approaches also grapple...

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> A workflow management system determines the flow of work according to predefined business process definitions. It manages resources required meet goals and provides monitoring facilities control capabilities. Resources can become important decision factors when combined with information. This is particularly true in an emergency response where large quantities resources, including responders,...

Hand gesture is a natural communication method which could be used to create more convenient interface for human-robot interaction. In this study, we use the simplest laptop camera as an input sensor. We designed 3D hand recognition model. The model trained with Jester dataset. After being about one day in MacBook Pro (i5 2.3GHz), reached average accuracy of 90%. built web application that implements system and provides service users.

Product disassembly is an effective means of waste recycling and reutilization that has received much attention recently. In terms efficiency, the number skills possessed by workers plays a crucial role in improving efficiency. Therefore, order to effectively reasonably disassemble discarded products, this paper proposes partial parallel line balancing problem (PP-DLBP) takes into account worker skills. paper, tasks relationships between components are described using AND–OR graphs....

Security system architecture governs the composition of components in security systems and interactions between them. It plays a central role design software that ensure secure access to distributed resources networked environment. In particular, must consistently assure policies it is supposed enforce. However, there currently no rigorous systematic way predict such critical properties design. A approach introduced address problem. We present methodology for modeling verifying whether...

Petri nets are a powerful formalism in modeling workflows. A workflow determines the flow of work according to pre-defined business process. In many situations, processes constrained by scarce resources. The lack resources can cause contention, need for some tasks wait others complete, which slows down accomplishment larger goals. our previous work, resource-constrained model was introduced and resource requirement analysis approach developed emergency response workflows, support on-the-fly...

In recent years, the global resource shortage has become a serious issue. Recycling end-of-life (EOL) products is conducive to reuse and circular economy can mitigate The disassembly of EOL first step for reuse. Disassembly activities need tools, tool deterioration occurs inevitably during process. This work studies influence on efficiency. A line balancing model with goal maximizing profits established, in which selection assignment critical part. modified discrete migratory bird optimizer...

The workflow management of incident command systems (ICSs) has been challenged by the systems' special requirements on flexibility, intuitiveness, and capacity correctness verification. significance applying formal approaches to modeling analysis workflows well recognized, many such have proposed. However, these require users master considerable knowledge particular formalisms, which impacts application a larger scale. This paper presents new formal, yet intuitive, approach for workflows,...

A health emergency is a situation that poses an immediate risk to and life requires urgent intervention prevent its worsening. Emergency healthcare service real-time service, where timeliness critical mission success. Workflow management technology has received considerable attention in the field recent years for automation of both intra- interorganizational processes. However, no work on analysis been reported. In our previous work, we proposed Workflows Intuitive Formal Approach (WIFA)...

Overcrowding in emergency departments (EDs) is a common problem encountered by healthcare systems worldwide. Its essence the imbalance between need for care and available resources, such as doctors, nurses, medical supplies, treatment facilities spaces. Such an increases with volume of visiting patients. To solve ED overcrowding, service providers to ensure rational allocation resources process greatest extent. This article uses stochastic timed Petri nets (STPNs) modeling simulation tool...
