Human errors (HEs) are prevalent issues in manual assembly, leading to product defects and increased costs. Understanding knowing the factors influencing human assembly processes is essential for improving quality efficiency. This study aims determine rank HEs based on expert judgments. To achieve this objective, an integrated model was developed using two multi-criteria decision-making (MCDM) techniques—specifically, fuzzy Delphi Method (FDM) Analytic Hierarchy Process (FAHP). Firstly, rounds of FDM were conducted identify categorize primary contributing assembly. Expert consensus with at least 75% agreement determined that 27 influence scores 0.7 or higher significantly impact these processes. After that, priorities a third round FAHP method.

This study examines the transformative role of digital platforms in fostering sustainable entrepreneurship within emerging economies. We argue that transcend mere communication channels, acting as catalysts for innovation and collaboration among startups, thereby driving economic, social, environmental progress. Our framework emphasizes platform-enabled navigating unique challenges opportunities presented by these dynamic markets. adopt a dual lens, using mixed-methods approach to analyze development trends through prism reframes discourse on technology-driven development, acknowledging unidirectional flow platform adoption from developed nations. The research need prioritizing sustainability standards regions. Furthermore, we delve into interplay between with following three objectives: (1) deciphering drivers platform–startup interaction goals, (2) formulating policies maximize benefits while mitigating risks, (3) developing actionable strategies stakeholders cultivate thriving ecosystem platform-based ventures. findings this reveal six key uncertainties will shape future trajectories ecosystems, particularly These encompass following: social standards, ongoing education mobile application utilization, global market access, competitiveness value creation. Several alternative scenarios have been constructed based uncertainties, including advancements technologies, conditions evolving consumer behaviors, heightened emphasis corporate responsibility, paradigm shift towards collaborative business models. A comprehensive supportive interventions has proposed facilitate realization scenarios. Moreover, analysis underscores pivotal roles providers startups landscape.

According to the UNHCR, 117.2 million people have been displaced in 2023, with rate and scale of displacement surpassing resources available assist those impacted. Modular construction is favored over traditional methods meet urgent demand for affordable housing as it overcomes challenges like long project timelines, high costs, safety environmental issues. However, manual assembly often slow prone errors, resulting inefficiencies higher costs. While advanced technologies could improve process, there limited research on automating modular construction. This aims assess how automation affects time efficiency cost aiming production by The follows a quantitative approach, collecting data through simulation evaluate effectiveness integrating robotics processes. It compares performance automated processes, focusing resource utilization, savings, implications. results reveal that manufacturing offers faster times improved efficiency, leading productivity lower overall By conducting detailed analysis, this provides insights can guide integration into manufacturing.

In the context of demand for mass customization products, a trade-off between highly efficient automated systems and flexible manual operators is sought. The linear arrangement workstations made it possible to divide process into many simple operations, which increases production efficiency, but also results in an increase number significant extension line. A human operator usually treated as quasi-mechanical object, error considered, similarly, failure technical component. However, behavior more complex difficult predict. mathematical model new organization presented, including dividing traditional line shorter sections or replacing serial assembly with U-line cells. Moreover, reliability means are distinguished. Work-in-progress inventories located improve system stability. stability examined based on configuration probabilistic estimates failure. influence symmetry parameters people key performance indicators (KPI (headcount), KPI (surface) (Overall Equipment Effectiveness) examined.
