Enhancing performance of construction waste management: Factor analysis from the building contractors’ perspectives

With the rapid growth of urbanization, construction projects have surged, increasing construction waste (CW). Effective construction waste management (CWM) is crucial to mitigate the adverse effects of CW on the environment, society, and the economy. This study aimed to identify critical attributes and factors that enhance CWM in building construction. Attributes were initially identified through a literature review and verified by 32 experts. Subsequently, a questionnaire based on the retained attributes was developed, and a survey was conducted with 304 construction professionals from the building construction sector in Cambodia and Thailand. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were sequentially conducted and further revealed five factors with a total of 27 attributes, namely Governance and policies (8 attributes), Materials and equipment (8 attributes), Requirements and specifications (4 attributes), Construction information systems (4 attributes), and Waste collection facilities (3 attributes). This study identified and confirmed the critical attributes and factors in enhancing the contractors’ CWM performance in building construction that are specifically within the 2 R strategy (reduce and reuse) that contractors can fully control on their construction sites. The findings provide empirical evidence to guide contractors in improving CWM in building construction projects. By enhancing all attributes across the five key factors, contractors can minimize CW and reduce the negative impact of construction activities on the environment and society, thereby contributing to sustainable construction practices.

Information on standardisation and standards as new indicators to forecast technological and industrial changes

ABSTRACT Product architecture changes fundamentally through the recombination of existing component technologies, as radical innovation accelerates. We analysed these structural changes in the case of the display industry. We shed light on standards information that could be new indicator to predict technological and industrial innovation. We addressed two issues. First, whether standardisation information is a leading indicator to detect and forecast technological and industrial changes. Second, whether standard information shows technological information flow signalling new technological fields. As methodology, we conducted case studies and empirical analysis using the information on standardisation and standards from the ‘activity process’ and ‘activity result’ viewpoint, respectively. As results, case studies showed a changing role from responsive to anticipatory standards by verifying that recent standardisation activities preceded the time of new product releases in world/Asian markets. We also found out that reconfiguration in the value chain that standardisation in component technologies has contributed to function technological fields. Network analysis using bibliographic information of standards revealed linkage patterns of technological knowledge flows with supporting the case studies. We propose the necessity of active participation in the standardisation process from industrial viewpoint with monitoring the industrial and technological trends. From policy viewpoint, we suggest construction and management of standards-related information system.

Construction of supply chain management information system based on networked web service composition technology

Web service composition is crucial for creating valuable services by integrating pre-existing ones. With their service-oriented architecture (SOA), which can be used for any system design, web services can increase flexibility. Fusing Web services architecture with Semantic Web services can better assist supply chain coordination in a distributive, autonomous, and ever-changing corporate environment than current information technology. Decisions must be made quickly and with enough information many systems fail to provide real-time supply chain insight. Forecasting, inventory management, and decision-making may all be impacted by poor data quality. Modifying preexisting systems according to unique organizational needs may be challenging and expensive. Hence, this paper proposes a semantic web service-based supply chain management framework (SWS-SCMF) to analyze the web services in supply chains and examine how they interact using Web Ontology Language (OWL)-S, including automated discovery, construction, and invocation. The suggested method for improving supply chain data integration uses an ontology-based multiple-agent decision support system. Different accessibility tools, data formats, management information systems, semantic web, and databases are integrated across the five interconnected levels of the system. Businesses may find the proposed approach useful for data and information sharing when dealing with complex supply chain management. The suggested SWS-SCMF is an adaptable, accurate, and effective method for bidirectional chaining composition that uses mediators to enable the automated composition of Semantic Web services. The numerical results show that our proposed method enhances the overall performance ratio by 94%, accuracy ratio by 98%, and supply chain management ratio by 91% compared to other methods.

Estimation of IT-project efforts for information system creation in the conditions of re-use of its functions

The object of this study is the process of estimation and control of an IT project. During the study, the problem of increasing the accuracy of estimating the efforts of an IT project to build an information system (IS) was solved. Research in this area is aimed at simplifying the original assessment methods or at applying elements of artificial intelligence to these methods. The task of the impact of the features of IS development methodology on effort assessment remains unexplored. During the study, the method of functional point analysis was modified. The proposed modification makes it possible to increase the accuracy of estimating efforts to build an IS under the conditions of re-using its individual functions. These conditions allow the construction of new system functions by reusing a previously developed function of the same system. The developed method was tested during the evaluation of efforts of an IT project to form the functional task "Forming and executing an individual plan for a research and teaching staff member of the department." The option of re-using one of the functions of a task during the construction of two other functions of the same task is considered. For this option, the estimate was 72 function points (the estimate using the standard method was 144 function points). The use of the results allows us to increase the accuracy in assessing the efforts of IT projects to construct IS under the conditions of applying the methodology of reuse of previously developed system elements. This, in turn, makes it possible to improve the accuracy of estimating time costs, personnel requirements, and financial costs for the implementation of IT projects for constructing IS. The results obtained are used to solve the task of estimating efforts during the planning of IT projects for developing information systems and their software

Fundamentals for formalizing the problem of information analysis architectures of intelligent training systems

Formulation of the problem. An analysis of the construction of information systems was carried out and the requirements for the appearance of intelligent training systems were determined. Model support for the analysis of an intelligent training system (ITS) is based on the use of modeling methods, their integration with existing methods and tools, providing dynamic modeling of the functional and structural properties of its information architecture. Target. To propose a new approach to formalizing the process of developing an ITS information architecture. Results. From the analysis of the content of educational and training tasks, general patterns have been identified that make it possible to apply system-forming principles to represent ITS, which comprehensively characterize the information process of modeling its information architecture based on the functional (F), structural (S) and information (I) aspects . The principles represent hierarchical categories, each of which reflects one of the levels of information interaction of models that make up the functional, structural and information levels of the interprogram interface, taking into account their level-by-level interaction. Each aspect of the consideration of models is characterized by content that generally reflects one of the aspects of the modeling object. In general, the principles reflect the paradigm of three-level information interaction of information objects, which uses for analysis existing approaches to modeling information architecture in the interests of implementing the invariant process of ITS functioning in relation to its pragmatic field. Information interaction between information objects represents the implementation of functional, structural and information relationships between objects and in their structure. Information relations in an ITS are determined by the presence of open ISF interfaces among information objects that form its information structure. The integrated model of these structures is a dynamic model of ITS, since informational and structural properties determine the conditions, and functional properties determine the nature of possible actions. Since the interaction levels are hierarchically coupled, the dynamic ITS model has a hierarchical structure. The implementation of interaction of information objects through ISF interfaces determines the transition of ITS to simulated states. The ITS information architecture model is presented in the form of a modular-cluster network structure. It is based on the principle of stratification of ITS into functional information models that implement the introduced aspects of the analysis of information interaction with grouping into clusters, reflecting the functional and structural properties of its information architecture. Practical significance. The functional and structural properties of the ITS information architecture were formalized on a variety of models (modules), their interfaces and information relationships, ensuring the development of a formal formulation of the problem of analyzing the ITS information architecture.

Utilization of an Information System for the Efficient Implementation of the Integrated Environmental Permit System in South Korea

The construction and operation of information systems are valuable for the implementation of an integrated environmental permit system (IEPS). This study introduces an IEPS and examines its implementation in South Korea. Using operational cases from the IEPS, we demonstrate how the system is structured for each permit application procedure and the mechanisms by which permits are processed. In South Korea, the operation of an IEPS has made it easy to track the progress of permits and immediately notify the relevant authorities regarding permit applications and supplementary requests, thereby reducing the time required for permit reviews and amendments. Furthermore, disclosing the review results and other permit information ensures the reliability of permits. Additionally, the regular input of data, such as pollutant monitoring data from facilities and compliance with permit conditions, into the IEPS facilitates the stable management of all data related to facility permits and operations. Regulatory agencies can utilize the database within the IEPS to gain insight into facility conditions before conducting on-site inspections, ultimately reducing the time required for such inspections. Moreover, by accessing past inspection records through this system, facilities requiring more focused management can be identified, and data from the system can be used in planning future inspections.
