Our robust framework integrates three innovative AI models for essential functionalities: road detection, traffic sign recognition, and obstacle avoidance. The system architecture, structured around a three layers “DDD” (Data, Detection, Decision) approach, involves meticulous data preprocessing for traffic signs and road data, followed by specialized Deep Learning models for each detection task, including a CNN for traffic signs, a CNN for road detection, and the pre-trained MobileNet-SSD for obstacle detection. A reinforcement learning agent in the Decision Layer processes these outputs for real-time control (steering, acceleration, braking) through a continuous learning process with environmental feedback. The research encompasses both extensive simulation in Unity, leveraging the ML-Agents toolkit for agent training across diverse environments, and crucial real-world deployment. Our reward/punishment system in the simulation environment, based on collisions with road markers and obstacles, refined the agent’s decision-making. The trained AI models were successfully exported and deployed onto a physical prototype, controlled by a Raspberry Pi and equipped with a camera and ultrasonic sensors. Real-world testing affirmed the robust performance of the physical model in detecting roads, recognizing traffic signs, and effectively avoiding obstacles. Quantitative results demonstrate compelling performance, including over 90% accuracy in obstacle detection and a 15% improvement in navigation efficiency compared to traditional algorithms under controlled simulation conditions. Model evaluation metrics show a 98% accuracy, 12% loss, and a prediction rate exceeding 77%.

Second, the attention mechanism is used to separately aggregate the category characteristics and numerical characteristics, which can dynamically identify the key contributing characteristics of the accidents at HRGCs. The HRGCs data from Louisiana, Texas, and Washington were employed for a comparative analysis with the baseline model, demonstrating and validating the superiority and practicality of the proposed deep learning model.

Thus, the focus of this work is to explore whether new material handling equipment has the potential to be deployed in a retail store environment to support omnichannel services. To do so, we designed and built a new picker-to-stock robotic platform to automate piece-level pick, sort, and place tasks in retail environments.

An iterative process determines the minimum amount of manual and robotic resources needed to operate the store that satisfies a given service level for online order fulfillment and replenishment tasks. Then to assess the economic viability of deploying such a robotic platform with the lab demonstrated values and with improved performance, these resource levels are then combined with operational metrics obtained from the simulation and various cost aspects via an economic analysis model.

This particular problem arises when certain products can serve as substitutes for others, an operation commonly observed in maintenance parts, electronics, pharmaceuticals, batteries, and various other industries. Unlike single-period/single-product inventory models, where closed form solutions like the classical newsvendor are available in the literature, the compatibility between multiple products across multiple planning periods has remained largely unexplored in previous research.&lt;/div&gt;&lt;div&gt;Thus, the objective of our study is to find the optimal order quantities of different product types in an inventory system to minimize shortages and expiration, taking into account the challenging aspects of perishability and the existence of compatible substitutes. To rigorously address the complexities of this inventory system, a mixed-integer linear programming (MILP) framework is developed to encapsulate the intricate structural and operational characteristics of the problem. The proposed model is designed to accommodate both deterministic and stochastic scenarios, enabling the derivation of exact and approximate solutions through the integration of advanced optimization and simulation-based methodologies.&lt;/div&gt;&lt;div&gt;For large-scale instances, we recognize the computational challenges that arise when using standard solvers. Consequently, a metaheuristic algorithm is developed, which is specifically designed to reduce the computational time required to solve big instances.

Compatibility also results in less order quantities. For a single inventory period, compatibility demonstrates higher effect on reducing the expected shortage and spoilage. For the case of full compatibility where any product can serve as a substitute for the others, closed form solution can be found for single period planning, while in multiple period planning, MILP optimization is required to address the problem. Finally, when compatibility is not present, it will lead to independent demand, thereby making the classical newsvendor problem applicable to this special case, but even in this case, optimization will be required for multi-period.&lt;/div&gt;&lt;div&gt;The proposed model exhibits broad applicability across a wide spectrum of industrial and medical applications, including but not limited to management of spare parts inventory, pharmaceutical supply chains, perishable food products such as dairy and ready-to-eat meals, the automo","PeriodicalId":55220,"journal":{"name":"Computers & Industrial Engineering","volume":"207 ","pages":"Article 111338"},"PeriodicalIF":6.7,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144480834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this model, farmers make decisions at planting and harvest stages under yield uncertainty, and processors and retailers have to cope with potential disruptions through contingency measures. AI is introduced into supporting planting decision, and players’ interactions and risk cascade effects are incorporated.

Second, AI makes the supply chain decisions for intertemporal products closer to those for non-intertemporal products, benefiting farmers, firms, and consumers. Third, AI can mitigate supply chain risks for non-intertemporal and low substitutable agricultural products more effectively than for other types of products. Finally, AI can also be a double-edged sword in specific scenarios, but the complementarity between AI and cold chain sharing enhances the efficiency of agricultural supply chains during unexpected disruptions.
