1889 Strategic Governance In Emerging Innovation Clusters: The Case Of Omexia, The Ai-driven Drug Development Cluster In Mexico
Authors: José Luis Meza de la Rosa, María del Rocío Soto Flores
Abstract:
This paper introduces the conceptual foundation of a strategic governance model tailored to emerging innovation clusters in regulated high-technology industries. Using the case of Omexia — the first Artificial Intelligence–driven cluster for pharmaceutical innovation in Mexico — the study proposes a theoretical framework to understand and guide the formation, coordination, and evolution of innovation ecosystems in economies undergoing industrial transformation.The governance of innovation clusters in emerging contexts faces multiple challenges: institutional fragmentation, weak public-private articulation, limited absorptive capacity in firms, and regulatory complexity in sectors such as biopharma. In response to these conditions, this paper outlines a governance model composed of three interdependent dimensions: (1) Institutional Architecture, referring to the structural configuration and roles of key stakeholders including academia, industry, government, and civil society; (2) Strategic Coordination Mechanisms, which involve leadership models, agenda-setting, funding strategies, and collaborative capabilities; and (3) Dynamic Governance Capabilities, understood as the capacity of the cluster to adapt, learn, and respond to technological convergence, particularly between artificial intelligence and biotechnology.The Omexia case serves as an illustrative context to explore the theoretical assumptions of the model. The cluster operates in a frontier space of technological convergence, where AI and molecular design are reshaping drug discovery and development. Its emergence raises critical questions about how governance structures can foster innovation, reduce systemic barriers, and align with national industrial and health policy objectives.Rather than presenting empirical findings, this paper focuses on building a conceptual framework that can support future applied research and strategic planning in cluster development. The model proposed is intended to be a diagnostic and design tool for stakeholders in innovation ecosystems, and a contribution to the theory of innovation governance in emerging economies.Keywords: innovation clusters, strategic governance, industrial development, emerging economies, institutional innovation

Authors: Krittin Kulrattanaruks, Aimaschana Niruntasukrat
Abstract:
In the era of Industry 4.0, reliable fault detection in rotating machinery is critical to minimizing unexpected downtime and maintenance costs. This study addresses the challenge of diagnosing compound faults, which consist of an unbalanced rotor, angular misalignment, and parallel misalignment, by introducing a baseline regression neural network for fault severity prediction. Fast Fourier Transform (FFT) was applied to the time-series vibration signal, producing amplitude features across multiple frequency ranges. A novel `smallest-severity normalization,’ where the minimum fault severity is considered as the unit severity, was introduced to enhance sensitivity to minor faults. Due to the imbalanced dataset, a stratified approach was used to split the data, ensuring that label distribution was consistent across training, validation, and test sets. Additionally, five-fold cross-validation was applied to the training data. To evaluate the accuracy of the neural network configuration, Root Mean Squared Error and Mean Error were used, while Mean Absolute Deviation from the Median was employed to assess its precision. The results reveal that limiting the input features to frequencies up to 750 Hz delivers the highest accuracy, with minimal error and slightly conservative severity predictions, which is an outcome that favors early warnings over missed detections. Conversely, including higher-frequency amplitude data increases noise and leads to underestimation of actual fault severity. These findings highlight the value of careful frequency selection and tailored normalization in multi-target fault diagnosis.Keywords: fault severity prediction, rotating machinery, compound fault dataset, neural network, predictive maintenance

Authors: Giuliana Schulz, Abigail Borja, Fiorella Duarte, Ivan Olmedo
Abstract:
This paper addresses the issue of long patient waiting times at Dajia Lee’s General Hospital during peak hours. The study identifies key contributing factors, including budget constraints, low digital literacy among elderly patients, and the hospital’s need to manage large volumes of foreign workers undergoing mandatory health checks. The project aimed to improve operational management and reduce waiting times in registration, payment, and pharmacy services without increasing staff or infrastructure costs. To achieve this, Six Sigma, discrete event simulation (FlexSim), and TRIZ were employed. A major finding was the inefficiency of the ticketing system, where many patients struggled with machine interaction, resulting in delays. Through simulation and root-cause analysis, the study pinpointed process failures and proposed targeted interventions. The most notable result was a significant reduction in average waiting times—from 18.81 minutes to under 4 minutes—with registered patients experiencing just 0.70 minutes. Queue balancing and pharmacy throughput also improved. These results confirm that integrating Six Sigma methodology with TRIZ-based process innovation and AI-driven prioritization can optimize hospital workflows effectively. The simulation-based approach enabled safe testing of improvements and helped address operational bottlenecks without disrupting services. This work presents a replicable and cost-efficient framework that hospital administrators in resource-constrained settings can use to enhance service quality and patient satisfaction. The project demonstrates the feasibility and measurable benefits of combining systematic process improvement tools and intelligent technologies in real-world healthcare environments.Keywords: simulation, six sigma, optimization, hospital efficiency management

Abstract:
The growing need for ever-changing customer demand pressurizes the manufacturing industry to look for a flexible and fast-changing small-volume production system. As a result, additive manufacturing (AM) is one of the fastest-growing methods of changing a 3D design model to a 3D product without any process planning method. The process is commonly called 3D printing technology and has found extensive applications in areas such as automotive, architecture, manufacturing, aerospace, thermal, flexible electronics, medicine, fashion, retail, and sports. A major aspect of 3D printing technology is its ability to produce parts that are not possible with traditional manufacturing techniques. The students at any level can be introduced to the technology and understand the theoretical aspects in coordination with practice in the laboratory. The paper examines the underlying 'rules' that help companies take full advantage of additive manufacturing technologies. The paper also examines the guidelines for the design of additive manufacturing with an in-depth discussion of design constraints. These guidelines are discussed with the view of creating lightweight parts, efficient heat exchangers, and components for the aerospace industry. The paper investigates different influencing variables, including the variation due to density and porosity. Other modeling equations that influence the additive process are examined, which include energy balance equations for melting and vaporization. Post processing of 3D additive components is also critical to the outcome of the overall process, as it impacts the resulting surface quality, total cycle time, and cost.Keywords: additive manufacturing case studies design guidelines, 3d printing of special materials, advanced fabrication, educating engineers

Authors: Maji I. Abubakar
Abstract:
In recent years, there have been increasing studies on the significance of human error on the efficiency and effectiveness of manufacturing systems. However, an in-depth analysis of the sources of human errors relating to manual assembly operations is still scanty, and a wider study of factors responsible for human error in manual assembly operations is lacking; therefore an effective approach to evaluating this phenomenon is needed. The Social Network Analysis approach is used in this study to systematically investigate the causality and influence of human error in manual assembly operations using data from the literature. The results of this study indicate that task complexity, training/experience, cognitive demand, and task time are the most significant factors liable for human error in manual assembly operations.Keywords: human error, manual assemble operations, manufacturing systems, social network analysis

Abstract:
An ‘incident’, according to the Information Technology Infrastructure Library (ITIL) framework, is a breach of service level, usually involving issues or defects observed in various IT software and hardware services. The increasing frequency of incidents within a telecom operator not only hinders employee performance but also has a direct impact on customer satisfaction and experience. Thus, it emphasizes the importance of minimizing these incidents as much as possible. This study aims to examine the underlying causes of incidents for a leading Pakistani Telecom operator and reduce the number of IT-related incidents. The DMAIC (Define, Measure, Analyze, Improve, Control) methodology, a principal component of Lean Six Sigma, is applied to improve existing processes and, as a result, enhance customer experience. Our process output variable is the weekly total incidents. Seventeen input variables were selected for analysis using data obtained from Services Manager software. Correlation and regression analysis identified key relationships, followed by Cause-and-Effect Diagrams and Why-Why Analysis to pinpoint root causes. During the improvement phase, the results highlighted the need to reform the ‘Change Management Process’ across the entire department and provide training on ‘Quality Management System’. Overall, implementing these solutions resulted in a more than 50% reduction in incidents, followed by an estimated $9,000 (PKR 1.2 million) savings for the organization.Keywords: incident, information technology, lean six sigma, quality management system

Abstract:
I. INTRODUCTION RSSB is the independent safety, standards and research body for Great Britain’s (GB) rail network. Our work targets six main areas: safer, healthier, harmonised, efficient, future, and sustainable rail and is underpinned by the latest rail-related research and data. II. PROJECT OUTLINE The United Kingdom’s (UK) Rail Accident Investigation Branch (RAIB) tasked the RSSB with the delivery of recommendations in response to an incident in 2021 that took place near Ramsden Bellhouse. J Widdows and T Hyatt from RSSB’s Human Factors (HF) team delivered two of the three recommendations set out by RAIB for industry. This paper will seek to explain the human factors approach taken to respond to the two recommendations from RAIB summarised below: 1) To clarify the roles and responsibilities of staff in circumstances where on-track plant is travelling, including the relevant rules and standards that apply to the control of on-track plant travelling movements. Also, the role of the machine controller during such movement, including where they should be positioned to discharge their duties and ensure personal safety. 2) Establish a mechanism for periodically reviewing the availability of obstacle detection equipment suitable for fitting to all types of on-track plant. III. PROJECT OBJECTIVES This project was a HF response to RAIB recommendations that were a result of a collision between two on-track plant (OTP) in Ramsden Bellhouse, Essex in 2021. It focused on understanding the role and responsibilities of a machine controller (MC) during travelling movements. The project also looked at error in cab design for OTP and communication to reduce the risk of striking obstacles, amongst other objectives. The overarching objective of the research project was to comprehensively respond to RAIB’s 2022 recommendation to reduce the risk of on-track plant (OTP) striking objects. HF methodologies and techniques used included observations, surveys, workshops, and an adaptation of the Systematic Human Error Reduction and Prediction Approach (SHERPA). Some of the outputs included a Human Factors Error Log (HFEL) and a user guide for UK infrastructure managers to assess new technology when purchasing or updating technology used in on track machinery (OTM). The UK rail industry is recommended to use the outputs referred to in this paper as part of an independent review of new technology to reduce the risk of OTP striking objects or other OTP on or near the line, as and when new technology becomes available and/or more cost effective for the GB rail industry, in addition to when retrofitting existing OTP. The paper identifies several human factors issues with current OTP cab designs, such as illogical braking controls and inconsistent feedback systems. IV. CONCLUSION This paper will highlight how the HF approach taken enabled the recommendations to be fully analysed in a real-world context, supported by experts and the final reports, to realise the benefits of the applied research project.Keywords: human factors and ergonomics in organisational design and management, human factors and ergonomics, integration of design, processes of human factors, technology-driven change, human-machine interface, control interface survey, on track plant, traveling movements, machine controllers, UK infrastructure, GB railway

Procedia PDF Downloads 641868 Optimizing Production Yield Through Process Parameter Tuning Using Deep Learning Models: A Case Study in Precision Manufacturing
Authors: Tolulope Aremu
Abstract:
This paper is based on the idea of using deep learning methodology for optimizing production yield by tuning a few key process parameters in a manufacturing environment. The study was explicitly on how to maximize production yield and minimize operational costs by utilizing advanced neural network models, specifically Long Short-Term Memory and Convolutional Neural Networks. These models were implemented using Python-based frameworks—TensorFlow and Keras. The targets of the research are the precision molding processes in which temperature ranges between 150°C and 220°C, the pressure ranges between 5 and 15 bar, and the material flow rate ranges between 10 and 50 kg/h, which are critical parameters that have a great effect on yield. A dataset of 1 million production cycles has been considered for five continuous years, where detailed logs are present showing the exact setting of parameters and yield output. The LSTM model would model time-dependent trends in production data, while CNN analyzed the spatial correlations between parameters. Models are designed in a supervised learning manner. For the model's loss, an MSE loss function is used, optimized through the Adam optimizer. After running a total of 100 training epochs, 95% accuracy was achieved by the models recommending optimal parameter configurations. Results indicated that with the use of RSM and DOE traditional methods, there was an increase in production yield of 12%. Besides, the error margin was reduced by 8%, hence consistent quality products from the deep learning models. The monetary value was annually around $2.5 million, the cost saved from material waste, energy consumption, and equipment wear resulting from the implementation of optimized process parameters. This system was deployed in an industrial production environment with the help of a hybrid cloud system: Microsoft Azure, for data storage, and the training and deployment of their models were performed on Google Cloud AI. The functionality of real-time monitoring of the process and automatic tuning of parameters depends on cloud infrastructure. To put it into perspective, deep learning models, especially those employing LSTM and CNN, optimize the production yield by fine-tuning process parameters. Future research will consider reinforcement learning with a view to achieving further enhancement of system autonomy and scalability across various manufacturing sectors.Keywords: production yield optimization, deep learning, tuning of process parameters, LSTM, CNN, precision manufacturing, TensorFlow, Keras, cloud infrastructure, cost saving

Abstract:
Industrial Engineering and Management (IEM) is a continuous, adaptable, and dynamic branch of engineering. The purpose of this study is to use a knowledge-based course classification method to investigate four IEM educational programs in Europe. Furthermore, the relative weight of each sector was determined using the credit value of the courses. IEM-specific locations and pooled areas were the two related kinds of areas that were used. The results show that, among the four program curricula, Production Management is the specific area with the largest weight, while the specialism field of IEM has a similar weight. This method has proved to be useful for curriculum analysis. The results show that one characteristic of IEM curriculum programs is diversity in the knowledge domains related to IEM specialism. The research also highlights the importance of an organized structure for defining IEM applications, allowing benchmarking efforts, and promoting communication between academics and the IEM community.Keywords: industrial engineering and management, knowledge areas, curriculum analysis, community
Procedia PDF Downloads 501866 Impact of Facility Disruptions on Demand Allocation Strategies in Reliable Facility Location Models
Authors: Abdulrahman R. Alenezi
Abstract:
This research investigates the effects of facility disruptions on-demand allocation within the context of the Reliable Facility Location Problem (RFLP). We explore two distinct scenarios: one where primary and backup facilities can fail simultaneously and another where such simultaneous failures are not possible. The RFLP model is tailored to reflect these scenarios, incorporating different approaches to transportation cost calculations. Utilizing a Lagrange relaxation method, the model achieves high efficiency, yielding an average optimality gap of 0.1% within 12.2 seconds of CPU time. Findings indicate that primary facilities are typically sited closer to demand points than backup facilities. In cases where simultaneous failures are prohibited, demand points are predominantly assigned to the nearest available facility. Conversely, in scenarios permitting simultaneous failures, demand allocation may prioritize factors beyond mere proximity, such as failure rates. This study highlights the critical influence of facility reliability on strategic location decisions, providing insights for enhancing resilience in supply chain networks.Keywords: reliable supply chain network, facility location problem, reliable facility location model, LaGrange relaxation

Abstract:
Maintaining the freshness and quality of perishable goods during distribution is a critical challenge for logistics companies. This study presents a comprehensive framework aimed at optimizing the distribution of perishable goods through a mathematical model of the Transportation Inventory Location Routing Problem (TILRP). The model incorporates the impact of product age on customer demand, addressing the complexities associated with inventory management and routing.

The hybrid algorithm combines Biogeographical Based Optimization (BBO) algorithms with local search techniques to enhance performance in small- and medium-scale scenarios, extending our approach to larger-scale challenges. Through extensive numerical simulations and sensitivity analyses across various scenarios, the performance of the proposed algorithms is evaluated, assessing their effectiveness in achieving optimal solutions. The results demonstrate that our algorithms significantly enhance distribution efficiency, offering valuable insights for logistics companies striving to improve their perishable goods supply chains.Keywords: perishable goods, meta-heuristic algorithm, vehicle problem, inventory models

Authors: R. Ananthanarayanan, S. B. Nakula, D. R. Seenivasagam, J. Naua, B. Sharma
Abstract:
Product packaging is a critical component of production, trade, and marketing, playing numerous vital roles that often go unnoticed by consumers. Packaging is essential for maintaining the shelf life, quality assurance, and safety of both manufactured and agricultural products. For example, harvested produce or processed foods can quickly lose quality and freshness, making secure packaging crucial for preservation and safety throughout the food supply chain. In Fiji, agricultural packaging has primarily been managed by local companies for international trade, with gradual advancements in these practices. To further enhance the industry’s performance, this study examines the challenges and constraints hindering the optimization of agricultural packaging practices in Fiji. The study utilizes Multi-Criteria Decision Making (MCDM) tools, specifically Interpretive Structural Modeling (ISM) and Cross-Impact Matrix Multiplication Applied to Classification (MICMAC). ISM analyzes the hierarchical structure of barriers, categorizing them from the least to the most influential, while MICMAC classifies barriers based on their driving and dependence power. This approach helps identify the interrelationships between barriers, providing valuable insights for policymakers and decision-makers to propose innovative solutions for sustainable development in the agricultural packaging sector, ultimately shaping the future of packaging practices in Fiji.Keywords: agricultural packaging, barriers, ISM, MICMAC

Authors: M. Hisham, S. Cabemaiwai, S. Prasad, T. Dauvakatini, R. Ananthanarayanan
Abstract:
A solenoid valve is an important part of many fluid systems. Its purpose is to regulate fluid flow in a machine. Due to the crucial role of the solenoid valve and its design intricacy, it is quite expensive to obtain in Fiji and is not manufactured locally. A concern raised by the local health industry is that the housing of the solenoid valve gets damaged when machines are continuously being used and this part of the valve is very costly to replace due to the lack of availability in Fiji and many other South Pacific region countries. This study explores the agile manufacturing of a solenoid coil housing using the Fused Deposition Modeling (FDM) process. An emergy study was carried out to analyze the feasibility and sustainability of producing the part locally after estimating a Unit Emergy Value (or emergy transformity) of 1.27E+05 sej/j for the electricity in Fiji. The total emergy of the process was calculated to be 3.05E+12 sej, of which a majority was sourced from imported services and materials. Renewable emergy sources contributed to just 16.04% of the total emergy. Therefore, the part is suitable to be manufactured in Fiji with a reasonable quality and a cost of $FJ 2.85. However, the loading on the local environment is found to be significant and therefore, alternative raw materials for the filament like recycled PET should be explored or alternative manufacturing processes may be analyzed before committing to fabricating the part using FDM in its analyzed state.Keywords: emergy analysis, fused deposition modeling, solenoid valve housing, sustainable production

Authors: Damous Mohamed, Zeroudi Nasredine
Abstract:
High-speed milling of thin-walled parts with complex curvilinear profiles often encounters machining instability, commonly referred to as chatter. This phenomenon arises due to the dynamic interaction between the cutting tool and the part, exacerbated by the part's low rigidity and varying dynamic characteristics along the tool path. This research presents a dynamic model specifically developed to predict machining stability for such curved thin-walled components. The model employs the semi-discretization method, segmenting the tool trajectory into small, straight elements to locally approximate the behavior of an inclined plane. Dynamic characteristics for each segment are extracted through experimental modal analysis and incorporated into the simulation model to generate global stability lobe diagrams. Validation of the model is conducted through cutting tests where acoustic intensity is measured to detect instabilities. The experimental data align closely with the predicted stability limits, confirming the model's accuracy and effectiveness. This work provides a comprehensive approach to enhancing machining stability predictions, thereby improving the efficiency and quality of high-speed milling operations for thin-walled parts.Keywords: chatter, curved thin-walled part, semi-discretization method, stability lobe diagrams

Abstract:
This study investigates the effect of sustainable supply chain management (SSCM) on the performance of agricultural firms in Nigeria. Green packaging, product design, waste reduction and supply chain design were examined. The ecological modernization theory, which suggests the economic benefit of the environment, was used to underpin the study. The research is quantitative in nature, and a survey research method was adopted where information was obtained using questionnaires distributed directly to the top managers of 6 agricultural firms in Nigeria. STATA and SPSS were used for the data analysis, and regression analysis was used to examine the effects. Findings showed that SSCM positively improves the performance of the firms. Also, detailed information about the study’s selected variables' effect on performance was provided. Additionally, the significant role of SSCM in accelerating the firms’ performance was highlighted. It is recommended that SSCM should be given serious attention by integrating it into the overall firm's business strategy.Keywords: sustainable supply chain management, green packaging, product design, waste reduction, supply chain design and performance
