Maximising Synergy: The Benefits of a Joint Implementation of Knowledge Management and Artificial Intelligence System Standards

Implementing management systems in organisations of all types and sizes often raises the following question: “What benefits will this bring?” Initial resistance and criticism are common as potential challenges are identified during the implementation process. To address this, it is essential to highlight the advantages of these systems and engage stakeholders in supporting management efforts. While the planning, implementation, use, maintenance, auditing, and improvement of management systems are generally voluntary, certification is frequently driven by external factors, particularly customer demands. Employees also stand to gain significantly, with knowledge and information serving as valuable resources, especially for leveraging artificial intelligence. This article explores the management’s readiness to adopt and fully utilise two management systems based on international standards: the ISO 30401 Knowledge management system (KMS) and the ISO/IEC 42001 Artificial intelligence management system (AIMS). Through interviews, we assess the challenges and solutions associated with implementing these systems, whether planned or partially adopted. The findings illustrate the synergistic benefits of integrating the KMS and AIMS, demonstrating how their combined use can enhance Integrated Management Systems (IMSs). Such integration supports comprehensive planning, operation, and performance evaluation of processes and services while also promoting continuous improvement.

Development and validation of a questionnaire (QSPC-Q) for assessment of quality and strengthening of primary care in Brazil.

The performance evaluation of services through instruments is relevant, as it can support thoughts, actions and political approaches to meet a social need. The objective of the article was to develop and validate the Quality and Strengthening of Primary Care Questionnaire (QSPC-Q) for professionals and users based on Starfield attributes and Donabedian pillars. A mixed sequential study was performed to develop the QSPC-Q. The test was applied to 149 doctors and 795 users of basic health units. Psychometric properties was assessed by testing internal consistency using Cronbach's alpha and exploratory factor analysis. Reproducibility od scale was assessed using intraclass cognitive and test-retest correlation. The final version of the follow-up consisted of 45 items aimed at physicians (Cronbach's alpha = 0.921) and 33 at users (Cronbach's alpha = 0.86); the intraclass respiratory capacity was 0.88. An exploratory factor analysis identified 13 factors associated with the pattern components. A short version with 29 items for professionals was also elaborated. Professional QSPC-Q (short and braided versions) and user QSPC-Q were valid.

Experimental study on deformation characteristics of new prestressed subgrade under static and dynamic loads

An in-deep comprehension of the static and dynamic operational characteristics of prestressed subgrade is essential for its analysis, design, and service performance evaluation. Based on the Buckingham π theory, a novel scaled static and dynamic model test system of the prestressed subgrade has been developed. The structural components, functional characteristics, and working mechanism of the test system were comprehensively elucidated, and a suite of static and dynamic model tests was conducted to study the deformation characteristics of the prestressed subgrade. It is demonstrated that the prestressed steel bars underwent prestress loss due to the additional stress induced creep of the soil elements below and adjacent to the load transfer plates (LTPs). Therefore, it is advisable to over-tension the prestressed steel bars in practical engineering. Upon the application of prestress, the subgrade surface experienced slight uplift deformation, which did not change the geometric shape and smoothness of the subgrade surface and demonstrated that the prestress reinforcement effect could diffuse to the subgrade surface. In the static double-load-plates tests, the prestressed subgrade presented obvious advantages in controlling the subgrade surface settlement and slope lateral deformation compared to the unreinforced subgrade, which could therefore improve the deformation resistance of the subgrade. In the short-term dynamic loading tests, both the acceleration and dynamic displacement of the subgrade approximately linearly decreased with an increase in the prestress, implying that the horizontal prestress had a notable beneficial impact on mitigating the subgrade vibration. Additionally, with the long-term dynamic loading, the prestress reinforcements could significantly restrain the cumulative plastic deformation of the subgrade, with the cumulative deformation decreasing as the applied prestress increased. The developed test system offers viable and implementable technical means for investigating the enhancement mechanism of a prestress reinforced subgrade, and the insights gained from the tests contribute to elucidating the effect of prestress reinforcements on the subgrade’s static and dynamic performance.

Family members use superficial justice information to evaluate performance of sheltered workshops: A warning about “cognitive shortcuts”

ABSTRACT Background A growing number of services are focused on people with intellectual disabilities. Our study investigates interpersonal justice (interpersonal treatment families receive from service professionals) perceived by family members as a heuristic (cognitive shortcut) they can use to evaluate service performance directed towards improving the quality of life of their relatives with intellectual disability. Method Using a sample of 86 family members, we tested a within-person model. Interpersonal justice and service performance were measured four times (T1–T4). Results Over time, changes in interpersonal justice were positively related to changes in service performance. Family members use the treatment they receive from professionals to superficially draw inferences (heuristic) about service performance. Conclusions Our study warns about the use of superficial justice information based on a heuristic to evaluate service performance. More active participation of families in the organizational life is suggested to avoid the use of these types of cognitive shortcuts.

Combined effects of local residual stresses, internal pores, and microstructures on the mechanical properties of laser-welded Ti-6Al-4V sheets

Laser-welded Ti-6Al-4 V is prone to severe residual stresses, microstructural variation, and structural defects which are known detrimental to the mechanical properties of weld joints. Residual stress removal is typically applied to weld joints for engineering purposes via heat treatment, in order to avoid premature failure and performance degradation. In the present work, we found that proper welding residual stresses in laser-welded Ti-6Al-4 V sheets can maintain better ductility during uniaxial tension, as opposed to the stress-relieved counterparts. A detailed experimental investigation has been performed on the deformation behaviours of Ti-6Al-4 V butt welds, including residual stress distribution characterizations by focused ion beam ring-coring coupled with digital image correlation (FIB-DIC), X-ray computerized tomography (CT) for internal voids, and in-situ DIC analysis of the subregional strain evolutions. It was found that the pores preferentially distributed near the fusion zone (FZ) boundary, where the compressive residual stress was up to -330 MPa. The removal of residual stress resulted in a changed failure initiation site from the base material to the FZ boundary, the former with ductile and the latter with brittle fracture characteristics under tensile deformation. The combined effects of residual stresses, microstructures, and internal pores on the mechanical responses are discussed in detail. This work highlights the importance of inevitable residual stress and pores in laser weld pieces, leading to key insights for post-welding treatment and service performance evaluations.

At the same time, the influence and correlation mechanism of hole-making quality and assembly accuracy on the mechanical properties of their connections are summarized from the hole-making processes and damage of composite/metal stacked structures.FindingsThe progressive damage analysis method can accurately analyze and predict the static strength failure of composite/metal stacked bolted joint structures by establishing a stress analysis model combined with composite material performance degradation schemes and failure criteria. The use of mature metal material fatigue cumulative damage models and composite material fatigue progressive damage analysis methods can effectively predict the fatigue of composite/metal bolted joints. The geometric errors such as aperture accuracy and holes perpendicularity have the most significant impact on the connection performance, and their mechanical responses mainly include ultimate strength, bearing stiffness, secondary bending effect and fatigue life.Research limitations/implicationsCurrent research on the theoretical prediction of the mechanical properties of composite/metal bolted joints is mainly based on ideal fits with no gaps or uniform gaps in the thickness direction, without considering the hole shape characteristics generated by stacked drilling. At the same time, the service performance evaluation of composite/metal stacked bolted joints structures is currently limited to static strength and fatigue failure tests of the sample-level components and needs to be improved and verified in higher complexity structures. At the same time, it also needs to be extended to the mechanical performance research under more complex forms of the external loads in more environments.Originality/valueThe mechanical performance of the connection structure directly affects the overall structural safety of the aircraft.

Service performance evaluation of light-transmitting concrete lane markings on highways based on accelerated pavement testing

Applying light-transmitting concrete (LTC) to highway lane markings is a novel idea to increase the visual recognition distance and promote traffic safety. However, compared to its excellent visual recognition performance, its service performance has received little attention in the current research. This paper conducted an accelerated pavement test to investigate the behaviour of rutting depth, British Pendulum Number (BPN) and water permeability coefficient of the LTC lane markings. The results show that rutting depth of LTC is lower than that of asphalt pavement. As a result, small height steps appeared at the seam of the two parts. For the anti-sliding performance represented by the BPN, the BPN of LTC gradually exceeds asphalt pavement and maintains a slightly higher value. For the water permeability coefficient, the LTC is almost un-permeable, avoiding water damage during service. According to these findings, the LTC lane markings meet the requirements of highway service performance. .

Fatigue test and service performance evaluation of high-speed train hanging equipment bolts

The high-speed train hanging equipment may extend maintenance cycle, prompting an urgent need for bolt service performance evaluation. In this paper, the hanging bolts of the hanging equipment of high-speed trains are taken as the research object, and accelerated fatigue tests of the hanging bolts under five alternating loads are designed and carried out. The SN curves of the bolts under axial loads are obtained with the Goodman modified equation and double logarithmic linear regression analysis, which provides a basis for acquiring the cycle life under different real vehicle loads. A tracking test system for real trains was established, and vibration acceleration data of four types of hanging equipment were obtained when the high-speed train was running on the Beijing-Shanghai high speed railway. An averaging method based on supervised classification was proposed, and the average daily acceleration load spectrum of different hanging equipment with cycle characteristics of 1.2 million km was constructed to provide data support for service mileage evaluation. A service mileage evaluation model of the hanging bolts based on the fatigue life model, Miner's rule and train dispatching rules was proposed. Moreover, the service mileage evaluation of four types of hanging bolt equipment was completed to provide an important reference for the formulation of a bolt repair system for the hanging bolt equipment of high-speed trains.

A Modular IoT-Based Architecture for Logistics Service Performance Assessment and Real-Time Scheduling towards a Synchromodal Transport System

Logistics is significantly impacted by quality/quantity issues associated with data collection and data sharing restrictions. Nonetheless, public data from national entities and internet-of-things (IoT) solutions enable the development of integrated tools for performance analysis and real-time optimization of logistics networks. This study proposes a three-module data-driven system architecture that covers (a) logistics data collection tools, (b) logistics services performance evaluation, and (c) the transition to synchromodal systems. Module 1 integrates multisource data from national logistics platforms and embedded devices placed within intermodal containers. A multigraph representation of the problem is conceived. Environmental, economic, and operational data are generated and injected into a digital twin. Thus, key performance indicators (KPIs) are computed by simulation or direct transformation of the collected data. Module 2 uses Multi-directional Efficiency Analysis, an optimization algorithm that benchmarks multimodal transportation routes of containers using prior KPIs. Outputs are a technical performance index relevant to logistics clients and improvement measures for logistics service providers. A real case study application of the solution proposed for Module 2 is presented. Module 3 provides real-time scheduling and assignment models using CP-sat solvers, accommodating varying system dynamics and resource availability, minimizing makespan and operational costs.

Optimal performance selection of sustainable mobility service projects based on IFSS - Prospect theory - VIKOR: A case study of electric vehicle sharing program.

Current mobility trend indicates that the number of private cars will decline in the near future. One of the reasons for this trend is the development of Mobility as a Service (MaaS), which in conjunction with information and communication technologies (ICT) drive the application of transport services in smart city, respond to environmental issues, and provide users with reliable mobility. Electric vehicle sharing (EVS) travel has been regarded as a feasible mainstream model of sustainable mobility services in the future, which can effectively improve the utilization rate of motor vehicles, solve the problems of traffic congestion, environmental pollution and urban land, and promote low-carbon and sustainable development. To help electric vehicle operators improve service quality, the establishment of EVS program service performance evaluation is an urgent problem to be solved. Based on this, this paper firstly constructs the evaluation index system from 5 aspects: electric vehicle, charge station, user experience, payment and intelligent services through literature review and Delphi method. Secondly, the criteria importance though intercriteria correlation (CRITIC) and the improved G1 method are introduced to overcome the shortcomings of the single method, and the combined weights are calculated by the multiplication normalization method. Finally, a decision model based on intuitionistic fuzzy soft set (IFSS)-prospect theory and VIse Kriterijumski Optimizacioni Racun (VIKOR) method is constructed to select the best service performance of EVS program, and its feasibility and effectiveness are verified by sensitivity analysis and comparative analysis. The result shows that EVCARD is the best performing EVS program, and shared electric vehicle and charge station are the key factors to be considered in the selection. This study provides scientific and feasible guidance for the optimal service performance selection of EVS programs, which is of great significance for users to choose EVS programs.

Measuring digital government service performance: Evidence from China

Digital services of the public sector are regarded as one of the most crucial aspects of the administrative system's reform. However, empirical studies on digital services are insufficient, especially for service performance evaluation. This paper establishes a conceptual framework to model service performance with quantity and quality output measures. Based on the panel data of Chinese cities from 2017 to 2020, we employ a one-step stochastic frontier analysis (SFA) to estimate the city's digital government service efficiency (DGSE) and examine its drivers. The findings suggest that the proposed analytical framework is applicable to the public sector performance measurement when quantitative and qualitative outputs are considered. Second, Chinese cities' DGSE levels ranged from 0.149 to 0.999, with a mean of 0.798. The DGSE score also shows significant spatio-temporal heterogeneity, with the eastern area performing best, followed by the middle and western regions, and the northeastern region performing the worst. Further, exogenous factors such as fiscal decentralization, public-private partnership, urban scale, the mayor's ability, and policy intervention substantially affect the DGSE level. The results have significant policy implications for governments' digital transition in the ongoing global digital era.

Interaction Between the Imperial Examination System and Politics and Its Limitations

The imperial examination system has been deeply influenced by the country's system category, historical tradition, and political system, which also determines its limited historical and realistic role in the political system. The imperial examination system extended the selection of officials to the whole society, provided a relatively fair opportunity for China's intellectuals to compete, and gave the country a wide range of political talents and a stable system. The civil service performance evaluation system established on this basis also has a positive reference value for curbing corruption. The imperial examination system in ancient China is an important system in Chinese history, which is an important part of ancient Chinese culture and an important symbol of Chinese history. This paper studies its profound influence and enlightenment on Chinese history and culture. At the same time, the paper studies that the imperial examination system is an important part of Chinese history and culture, which promotes the development of Chinese bureaucracy, cultivates Chinese cultural tradition, promotes social mobility and social progress, and also highlights China's cultural self-confidence and cultural consciousness. While the imperial examination system is an education based on political needs, after education it can impact politics, which forms a circular structure. This reflects interactions between the imperial examination system as the carrier of ' education' and politics. However, in ancient China there will inevitably be some limitations.

Radiation Dose Tracking in Digital Mammography: Evaluation of Population Profiles through Automatic Data Extraction from the DICOM Header

International regulatory organizations for quality control of X-ray systems, such as the International Atomic Energy Agency (IAEA), have implemented protocols for acceptance testing of digital mammography and breast tomosynthesis equipment, aiming to establish quality standards in radiology services. However, these guidelines are usually based on tests with breast phantoms with standardizedthicknesses and compositions, often not representative of the patient population profiles at those services. In a prior study, we developed a computational system designed to automatically tracking and managing data extracted from the image acquisition processes of digital mammography and breast tomosynthesis, stored on a DICOM SCP (Service Class Provider) server. This approach enables obtaining technical reports characterizing exposure parameters and tests have shown that the reference levels outlined in international standards for breast composition and radiation dose do not accurately reflect the characteristics of the actual patient population. Thus this study describes data collection and corresponding analysis for the dose tracking process primarily on three digital mammography systems of different radiological services. Extensive image datasets from these systems were obtained using a new application described previously, with a focus on dose profiles generated during exposures. Graphical representations resultingfrom the datasets are presented, along with analysis of skin entrance and mean glandular doses distributions, average kV and mAs applied during the exams together with the target/filter combinations, radiographic density distribution, as well as the age and breast thickness characteristic of the respective population submitted to exposures in each of those mammography services. Additionally, the extent of information and ease of acquisition provided by the tool for performance evaluation of digital mammography services is discussed

The construction of a shared resource base of enterprise financial informationization for intelligent terminal platform

Abstract This paper uses an adaptive load-balancing algorithm to calculate an intelligent terminal platform on the basis of an enterprise financial information-sharing model. Firstly, a new server performance evaluation index is established based on the hierarchical analysis method, and the load performance of each node is reacted using the influence factors. Then a judgment matrix is constructed for the set of evaluation factors based on the change in the average load utilization rate of nodes. Finally, the results of the matrix are normalized to derive the evaluation weights of each node of the server, which completes the construction of the intelligent terminal platform. An enterprise’s quarterly bills for 2018-2020 were selected for analysis, and after running the financial information sharing, the processing time of a single voucher could be saved by 0.3 hours. It shows that the constructed information-sharing resource base can not only significantly reduce operation costs but also access the business data of subsidiaries at any time to effectively prevent operation risks.
