This study explores the integration of clearing function (CF)-based release planning into Material Requirements Planning (MRP) systems, with a focus on mitigating the inherent rigidity of MRP in handling variability in production environments. By replacing the backward scheduling step of MRP with a CF-based optimization model, this work investigates its impact on overall costs, lead times, and system performance in multi-item, multi-stage production systems. Computational experiments were conducted on two distinct systems - a simple and a complex production system - under varying demand behaviors and utilization levels. The findings reveal that the CF-based release order planning consistently outperforms traditional MRP in managing cost and variability, particularly under scenarios of higher demand uncertainty and shop load. While MRP demonstrates stability in less complex scenarios, its inability to adapt dynamically to variability leads to higher costs in most conditions. The analysis underscores the potential of CF-based methods to enhance planning efficiency in dynamic production settings, providing a foundation for future research on integrating capacity constraints within the broader MRP framework. © 2025, CC BY.

To achieve CO 2 neutrality in 2050, internal combustion engine vehicles will be gradually substituted by electric vehicles since they enable an emission-free use phase if powered with renewable energy. However, producing lithium-ion batteries for electric vehicles is associated with high environmental impacts and economic challenge such as supply bottlenecks. Seeking to tackle these challenges by integrating recovery activities, car and battery manufacturers are increasingly transforming their production systems to circular production. Yet, transforming the entire production system poses several risks and uncertainties, e.g., technological developments and regional political instabilities. Therefore, a robust transformation toward a sustainable circular battery production is needed. Using a scenario design approach, we envision sustainable circular battery production in 2050 and the correlating transformation with minimum total CO 2 emissions throughout the transformation process. To consider the potential enablers, inhibitors, and feasible (counter)measures, we conducted a workshop with experts from life cycle engineering, mechanical engineering, and business economics. Based on the results, both technological enablers and fundamental challenges of sustainable circular battery production were derived, which have to be addressed in the context of life cycle engineering.

作者： Anam, Md. Zahidul Islam, Md. Hasibul Islam, Md. Tamzidul Bari, A.B.M. Mainul Raihan, Asif Department of Operations and Supply Chain Management American International University-Bangladesh Dhaka 1229 Bangladesh Department of Industrial and Production Engineering Bangladesh University of Engineering and Technology Dhaka 1000 Bangladesh Institute of Forestry and Environmental Sciences University of Chittagong Chittagong 4331 Bangladesh

The adoption of digital technologies in agriculture offers opportunities for efficiency and sustainability, particularly in emerging economies with resource and infrastructure constraints. However, challenges persist, exacerbated by crises such as COVID-19 and geopolitical instabilities, highlighting agricultural supply chains’ fragility. Industry 5.0-driven digital transformation (DT) can mitigate these challenges by enhancing food security, supply chain resilience, and environmental sustainability. This study identifies and analyzes key drivers of DT in agricultural production from a holistic perspective. Through a literature review and expert validation, 19 key drivers were identified in the context of Bangladesh. An integrated multi-criteria decision-making (MCDM) approach, combining the Fermatean fuzzy sets (FFS) with the decision-making trial and evaluation laboratory (DEMATEL) technique, was applied to examine the drivers and explore interrelations among them. The results indicate that the most influential drivers are ’commitment from regulatory bodies’, ’maximizing the use of dwindling resources’, ’fostering rural development’, and ’the need for safe food’, with prominence values of 4.175, 4.001, 3.999, and 3.888, respectively. Additionally, ’commitment from regulatory bodies’ emerges as the most impactful causal factor, having a causal weight of 1.848. These findings provide insights for policymakers and industry managers in emerging economies, supporting strategic decision-making to drive sustainable agricultural transformation and achieve the relevant sustainable development goals. © 2025 The Authors

Purpose: The purpose of this study was to create an air movement operations planning model to rapidly generate air mission request (AMR) assignment and routing courses of action (COA) in order to minimize unsupported AMRs, aircraft utilization and routing cost. Design/methodology/approach: In this paper, the US Army Aviation air movement operations planning problem is modeled as a mixed integer linear program (MILP) as an extension of the dial-a-ride problem (DARP). The paper also introduces a heuristic as an extension of a single-vehicle DARP demand insertion algorithm to generate feasible solutions in a tactically useful time period. Findings: The MILP model generates optimal solutions for small problems (low numbers of AMRs and small helicopter fleets). The heuristic generates near-optimal feasible solutions for problems of various sizes (up to 100 AMRs and 10 helicopter team fleet size) in near real time. Research limitations/implications: Due to the inability of the MILP to produce optimal solutions for mid- and large-sized problems, this research is limited in commenting on the heuristic solution quality beyond the numerical experimentation. Additionally, the authors make several simplifying assumptions to generalize the average performance and capabilities of aircraft throughout a flight. Originality/value: This research is the first to solve the US Army Aviation air movement operations planning problem via a single formulation that incorporates multiple refuel nodes, minimization of unsupported demand by priority level, demand time windows, aircraft team utilization penalties, aircraft team time windows and maximum duration and passenger ride time limits. © 2022, In accordance with section 105 of the US Copyright Act, this work has been produced by a US government employee and shall be considered a public domain work, as copyright protection is not available.

While circularity has gained significant attention in recent years, the wood products industry remains an understudied sector in terms of remanufacturing practices. This study addresses this research gap by synthesizing the existing research on remanufacturing in the wood products industry and developing a research agenda tailored to the European context based on a structured literature review. Content and thematic analyses of peer-reviewed publications founded the basis of the synthesis. Three distinct perspectives on remanufacturing in the wood products industry emerged from the analysis: systems, customer, and manufacturer. These perspectives provide a framework for understanding the complex dynamics of remanufacturing in this sector. The proposed research agenda for the European context is intended to stimulate and guide future research efforts. A central priority identified is the need for enhanced collaboration and communication among actors within the value chain. Additionally, the importance of gaining a deeper understanding of customer perceptions and behavior in the context of remanufactured wood products is recognized. The development of economically viable remanufacturing strategies is another key focus. This knowledge is crucial for tailoring products to meet consumer needs and preferences, ultimately driving demand for remanufactured items. In conclusion, remanufacturing in the wood products industry is an area ripe for exploration, and this study represents a critical step towards catalyzing the research efforts necessary for its advancement. © 2024 The Authors

Ergonomics-based sustainability (EBS) in public utility vehicles (PUVs) requires an integrated approach that balances environmental, social and economic factors while enhancing commuter and driver well-being. This study develops an EBS framework for PUVs in the Philippines by integrating higher-order structural equation modelling (H-SEM) and the random forest classifier (RFC). Analysing 350 survey responses, results indicated that environmental sustainability, particularly pollution reduction and energy efficiency, had the greatest influence on overall sustainability. Social dimensions, such as driver well-being and vehicle safety, were also critical, while economic factors like affordability and investment played a supporting role. The RFC model highlighted immediate operational concerns, emphasising safety and usability, which complement SEM's long-term sustainability insights. This study provides a data-driven framework for policymakers and transport planners to improve PUV ergonomics, enhance commuter satisfaction and promote sustainable mobility, with adaptability for global applications in EBS.

Procedia CIRP 2023年 116卷 618-623页

In 2015, the United Nations General Assembly proposed seventeen Sustainable Development Goals (SDGs) intended to ensure sustainable development worldwide at the economic, environmental, and social levels. SDGs are now being used by some corporations in formulating and expressing business strategies. However, assessing the effects of corporate activities and products regarding their contribution to SDGs is difficult. In this paper, we have developed a method for linking life cycle sustainability assessment (LCSA) with the SDGs and calculating the contribution to SDG achievement. An essential part of this approach is the weighting of LCSA impact categories, which is typically done using equal weighting. This weighting method enables compensation of negative contributions by positive contributions in different impact categories but results in ambiguity in the results. This article identifies alternative weighting methods, integrates them into a computational approach, and determines their influence on the SDG contribution scores. The analysis shows that the use of alternative weights changes SDG contribution scores. However, the same product always has the highest SDG contribution score, regardless of the weighting method used. Nonetheless, the recommendations for action with regard to the total product alternatives would change depending on the weighting method.

A systematic review of vehicle routing problems and models in multi-echelon distribution networks

Supply Chain Analytics

引用

Supply Chain Analytics 2024年 7卷

作者： Nielsen, Peter Dahanayaka, Mahekha Perera, H.Niles Thibbotuwawa, Amila Kilic, Deniz Kenan Department of Materials and Production Aalborg University Aalborg 9220 Denmark Center for Supply Chain Operations and Logistics Optimization University of Moratuwa Katubedda 10400 Sri Lanka Department of Transport Management and Logistics Engineering University of Moratuwa Katubedda 10400 Sri Lanka

The vehicle routing problem (VRP) is a combinatorial optimization problem that determines optimal routes to enhance distribution efficiency. One of the most popular strategies in freight distribution is multi-echelon distribution. Multi-echelon distribution networks often apply to supply chain management, land transportation, the maritime industry, aviation, etc., and rely on VRP. This comprehensive review systematically analyses 382 papers retrieved through the Scopus database. We use a bibliometric and network analysis tool to complete a systematic literature mapping identifying key interrelationships and research clusters. The analysis depicts five main research clusters: green logistics and decision analysis, scheduling and inventory optimization, VRP for city logistics, mathematical modeling and optimization, and outbound logistics and customer service, identified based on author keywords of the systematically derived paper pool. Each cluster is provided with foundational knowledge, concepts, theories, and employed techniques. Finally, future studies are suggested to explore more comprehensive investigation in highly discussed domains like city logistics problems in e-commerce, vehicle routing problems for sustainable logistics, and technological advancement-based applications. © 2024 The Authors
