Business Process Reengineering (BPR) eliminates non-value-added (NVA) and essential non-value-added (ENVA) waste through radical process redesign to improve organizational operations. Comprehensive research integrating BPR tools is needed to understand their benefits for manufacturing firms. This research presents an integrated BPR-simulation framework tailored to the manufacturing sector to maximize process improvements and operational excellence.

The BPR design methodology adopts a systematic, multi-stage approach. The first phase involves identifying a specific improvement process aligned with BPR's core objectives. This phase analyses and redesigns workflows to optimize task sequences, roles, and stakeholder interactions while eliminating redundancies and inefficiencies via Workflow Process Reengineering. Visual process mapping tools, including VSM and simulation, pinpoint areas of waste, delay, and potential enhancement. The second phase follows the workflow analysis and aims to improve efficiency and effectiveness by redefining roles, rearranging tasks, and integrating automation and technology solutions. The redesigned process undergoes evaluation against key performance indicators to ensure measurable improvements are achieved. The final phase validates the proposed changes through simulation models, assesses the impact on key performance metrics, and establishes the necessary infrastructure for successful implementation. The proposed model is empirically validated through a case study of a leading apparel company in Vietnam, confirming its effectiveness.

The findings reveal that NVA activities are being eliminated, and ENVA activities in key departments are significantly reduced. This yielded a substantial improvement, reducing 25 out of 186 combined ENVA and NVA operations in the sewing facility, involving a decrease of 15 ENVA operations and the removal of 10 NVA operations. Consequently, this led to an 8.5% reduction in the proportion of ENVA operations, accompanied by a complete 100% elimination of NVA activities.

The single case study limits generalizability; thus, expanded implementation across diverse manufacturing sub-sectors is required to establish validity and broader applicability of the integrated framework.

The experimental results highlight the proposed model's effectiveness in optimizing resource utilization and its practical implementation potential. This structured BPR methodology enables organizations to validate, evaluate, and establish proposed process changes to enhance operational performance and productivity.

The purpose of this paper is to study and analyze the effects of fly ash (FA) as a mineral admixture on compressive strength (CS), carbonation resistance and corrosion resistance of reinforced concrete (RC). In addition, the utilization of inexpensive and abundantly available FA as a cement replacement in concrete has several benefits including reduced OPC usage and elimination of the FA disposal problem.

Reinforcement corrosion and carbonation significantly affect the strength and durability of the RC structures. Also, the utilization of FA as green corrosion inhibitors, which are nontoxic and environmentally friendly alternatives. This review discusses the effects of FA on the mechanical characteristics of concrete. Also, this review analyzes the impact of FA as a partial replacement of cement in concrete and its effect on the depth of carbonation in concrete elements and the corrosion rate of embedded steel as well as the chemical composition and microstructure (X-ray diffraction analysis and scanning electron microscopy) of FA concrete were also reviewed.

This review provides a clear analysis of the available study, providing a thorough overview of the current state of knowledge on this topic. Regarding concrete CS, the findings indicate that the incorporation of FA often leads to a loss in early-age strength. However, as the curing period increased, the strength of fly ash concrete (FAC) increased with or even surpassed that of conventional concrete. Analysis of the accelerated carbonation test revealed that incorporating FA into the concrete mix led to a shallower carbonation depth and slower diffusion of carbon dioxide (CO₂) into the concrete. Furthermore, the half-cell potential test shows that the inclusion of FA increases the durability of RC by slowing the rate of steel-reinforcement corrosion.

This systematic review analyzes a wide range of existing studies on the topic, providing a comprehensive overview of the research conducted so far. This review intends to critically assess the enhancements in mechanical and durability attributes (such as CS, carbonation and corrosion resistance) of FAC and FA-RC. This systematic review has practical implications for the construction and engineering industries. This can support engineers and designers in making informed decisions regarding the use of FA in concrete mixtures, considering both its benefits and potential drawbacks.

This chapter examines the current educational provision in Brazil, with a specific focus on inclusive education and how this is provided in the country. Students who experience disadvantage due to disabilities, living in poverty, gender and geographic isolation are often most at risk for not accessing education, or being provided with poor quality education which may not meet their needs. Supports and barriers to inclusive education are examined within Brazil's existing political and social context. The role of technology in supporting inclusion is also examined.

Industry 4.0 (I4.0) influences the supply chain, including innovation, structure, availability and communication. It influences the supply chain by modifying how products are designed, manufactured, delivered and discarded for the sustainability of an organization. Sustainability emphasizes the use of optimal raw materials, efficient storage and delivery, on-time supply, productivity development, recycling, remanufacturing and refurbishing. The aim of this study is to identify and establish causal relationships among the key aspects that contribute to the success of I4.0-enabled sustainable supply chain (I4eSSC). The objective is to classify these components into discrete categories according to their causal and consequential linkages.

This paper presents a three-phase hybrid Criteria Importance Through Inter-criteria Correlation and Grey Decision-Making Trial and Evaluation Laboratory (G-DEMATEL) framework to achieve the stated objectives. A study is conducted to empirically examine the Indian automobile sector in order to illustrate the suitability of the suggested framework.

During the initial stage, a total of 26 success factors have been identified for the I4eSSC implementation. During the second part of the study, a total of 20 success factors were found and deemed critical success factors (CSFs). During the concluding stage, it was seen that out of the total of 20 chosen CSFs, nine were categorized in the cause group, whereas the remaining 11 were classified under the effect group. The analysis revealed that the element of “adoption of emerging technology for sustainable product and process development” was assigned the greatest level of importance.

This study aims to motivate professionals to enhance the integration of I4.0 into sustainable supply chains to maximize the advantages offered by these two separate concepts. It is imperative to devote genuine consideration to the examination of causal group variables in the context of I4eSSC, since these elements possess a direct influence on the overall performance of systems and exert a significant impact on the components within the effect group.

This study presents an extensive compilation of CSFs pertaining to the implementation of I4eSSC. The primary objective is to determine the relative relevance of these factors and explore the intricate causal relationships that exist among them. Furthermore, this study stands out due to its novel application of a specific decision-making methodology within the field of I4eSSC.

There are two main objectives in this study. First, we aim to develop a set of constructs for health task management support (HTMS) features to evaluate which health-related tasks are supported by mobile health application (mHealth app) functions. Second, drawing on innovation resistance theory (IRT), we examine the impacts of the newly developed HTMS dimensions on perceived usefulness, alongside other barrier factors contributing to technology anxiety.

Using a mixed-method research design, this research seeks to develop new measurement scales that reflect how mHealth apps support older adults’ health-related needs based on interviews. Subsequently, data were collected from older adults and exploratory factor analysis was used to confirm the validity of the new scales. Partial least squares structural equation modeling (PLS-SEM) was used to analyze survey data from 602 older adults.

The PLS-SEM results indicated that medical management task support, dietary task support, and exercise task support were positively associated with perceived usefulness, while perceived complexity and dispositional resistance to change were identified as antecedents of technology anxiety. Perceived usefulness and technology anxiety were found to positively and negatively influence adoption intention, respectively.

This study enriches the information systems literature by developing a multidimensional construct that delineates how older adults’ health-related needs can be supported by features of mHealth apps. Drawing on IRT, we complement the existing literature on resistance to innovation by systematically examining the impact of five types of barriers on technology anxiety.
