abstract = {Analyzing the assembly line balancing problem with cobots on parallel adjacent assembly lines is the main objective of this research. On the assembly line, human workers and robots, or cobots, are permitted to work in parallel or independently. There are two categories of workers in the assembly lines: workers without disabilities and workers with disabilities. Workstations are assigned jobs, workers, and cobots in order to accomplish system-, human-, and robot-related goals. The well-known evolutionary methodology of the Non-dominated Sorting Genetic Algorithm (NSGA-III) is utilised to identify optimal solutions because the problem is NP-hard. Workers with disabilities exist, thus their effects on the system's objectives are examined. It has been shown that how workers with disabilities have a substantial effect on assembly line efficiency. © 2024 Owner/Author.},

abstract = {Objective: To improve patients’ experience concerning insufficient informational flow to patients waiting at the dispensary station–case study of a traditional Chinese medicine clinic. Method: The service system was explored via qualitative techniques such as interviews and constructing the customer journey map. Then, experience and operational issues were defined through experience ratings at each touchpoint, patient interviews, and root cause analysis. The solution was identified via brainstorming and prototyping. A prescription tracking system was proposed with a finish time estimation algorithm. Results: The overall satisfaction score at the dispensary station, comparing before-after system implementation in 2019, was increased 37% from the average score of 3.27 to 4.47 using 5-point Likert scales. The mean absolute percentage error (MAPE) of the waiting time estimation model that included the buffer time (upper bound at 95%) is 52%. Conclusion: This methodology, which included both patient experience and operational improvement viewpoints, could successfully improve both the patient experience and the related operation system at its critical touchpoints. Moreover, the data from the prescription tracking system could be used to estimate the number of patients waiting in the system, allowing the clinic to better manage its waiting space and capacity during the COVID-19 pandemic. © 2022 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {This research focuses on a framework for making decisions when adopting collaborative robots (cobots) to collaborate with or replace human workers. Top management at a real-life case study firm that manufactures a variety of eyeglasses lenses wants to implement cobots in the sorting process since such a repetitive task has been shown to have a significant negative influence on workers' ergonomic ailments. Its current procurement decision-making process focuses solely on financial perspectives without taking into account any other significant criteria. Therefore, the purpose of this study is to investigate the elements that are crucial in deciding whether to use cobots in manufacturing lines., Multivariate statistical methods, comprising the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), are applied to analyse the elements that are associated with the latent variables such as safety, ergonomics, productivity, quality, system, internal organisation and external organisation. In addition, alternative deployments of cobots in the case study are validated through the ARENA simulation software. More specifically, the results showed that using cobots in the workplace might boost output while lowering WIP, waiting times, the number of tasks in queue, and the workforce. In addition, cobots may reduce employee ergonomic risk and enhance workplace safety. © 2023, Chulalongkorn University, Faculty of Fine and Applied Arts. All rights reserved.},
