While the engineering design research community has developed numerous models for early-stage design over the years, these models explore the design space corresponding to the dominant solution in the domain. These models work well for making predictions for designs by experts within an organization, but they cannot compare solutions that use alternative principles to solve the same problem. With the increasing popularity of open innovation and crowdsourcing within engineering design organizations, it is important to value the non-traditional solutions from non-traditional solvers in the early-stage design to make informed decisions about structuring the problem-solving mechanism employed by the organization. This paper attempts to create a new modeling framework to predict the design outcome by valuing non-traditional solutions alongside the dominant solution, thereby capturing the potential performance and novelty offered by the solutions from the non-traditional solvers. The model is demonstrated using a case study of a robotic gripper design. The results indicate the model can predict the best solution for the same problem across different principles. In addition, we find that the model is more important for non-traditional solvers than traditional solvers, as a larger fraction of their solutions would have been missed by models considering only the dominant solution.

This study seeks to address the resource constraint and module development sequencing issues associated with the non-preemptive product development (PD) process. We specifically consider the development of multiple product variants from a common product family where the product variants may share one or more common modules, and each product variant emerges only after the completion of its associated module(s). Furthermore, the modular configuration of each product variant is known a priori, and each module is defined by a specific set of attributes. Given the constraint of PD resource and the stringency of modular configuration for product modules, the goal of this study is to develop an approach for determining the development sequence which maximizes the net revenue associated with the PD process upon product release. The approach will utilize parameters relevant to the conventional PD process and we proceed to develop a mathematical model to define the problem. We conclude by demonstrating the applicability of the model using a realistic case example and discuss the insights and managerial implications of the study. © 2023 IISE Annual Conference and Expo 2023.

Emerging with aging populations in developed countries, continuously rising incidences of fall has consistently raised the concern in elderly and long-term care. In this research paper, the relationship between Berg Balance Scale (BBS) and elderly movement data captured by wearable accelerometers are determined. In situations where it is not known if the elderly is prone to falls, a clustering model is established to segment different groups of distinguished gait pattern and evaluate the feasibility to stratify the risk of falling variates with the harmonic ratio of measurements in three perpendicular directions during gait pattern assessment. It purely relies on the measurements of body movement without any judgement subjected to individual medical professional which opinions even can be variated among each other. Robustness of this model are further verified by appropriate tests of statistical significance. The present study, as an authentic complement, evaluates the effectiveness of using wearable accelerometers to assess the fall risk for elderly. It is also an alternative reference for IoT or wearable device manufacturers to further research and develop a system to estimate fall risk individually, predict any fall activity and thus prevent from its occurrence. © 2023 Newswood Limited.

This preliminary paper presents a Systematic Literature Review (SLR) to explore how consumer brand love of Micro, Small, Medium Enterprises (MSME) in Indonesia could be enhanced through branding strategies. MSMEs play important role in current Indonesia economic growth, but unfortunately, they focus on the trading and forget about the branding. It also examines previous research to observe what should be highligted about brand love, how to identify the variables of the consumer voices and if the latent consumer voices has been identified. To collect the literature data, ScienceDirect and Google Scholar were used as databases. There is a contradictive thing about the masstige brand and MSME's brands about brand love, brand loyalty and purchase intention. Some recommendations strategies could be determined such as good collaboration between the government and MSMEs, and how to gather the latent consumer voice. For further research could be suggested to include interview that would be converted to text document. © 2024 IEEE.

eLearning has been utilized as a mode of instruction among medical students amidst the COVID-19 pandemic. The present study aimed to investigate the factors influencing the acceptance of eLearning platforms in medical education during the COVID-19 pandemic in the Philippines by employing the latent variables of UTAUT2, along with two additional latent variables gathered from various related literature. A sum of 360 medical students participated and answered an online survey that consists of 40 questions. A stepwise multiple linear regression was utilized and found that performance expectancy (PE), habit (HB), and instructor characteristics (IC), can successfully predict the actual use (AU) of medical students with a precision of 54.22%. A higher performance expectancy (PE), habit (HB), and instructor characteristics (IC) can enhance and promote the acceptance of medical eLearning platforms. This is the first study that has examined the acceptance of eLearning platforms among medical students in the Philippines during the COVID-19 pandemic. The outcomes of this research can serve as guidelines for the Commission on Higher Education of the Philippines for the enhancement of eLearning platforms. Although this study only utilized the latent variables of UTAUT2 along with two additional variables: Learning Value and Instructor Characteristics;the findings of this study would still hold significant value for promoting open innovation in eLearning platforms in medical fields worldwide. © 2024 Copyright is held by the owner/author(s).

This research aims to find the best open-source blockchain platforms for use in agriculture, providing businesses with a solid foundation and helping them avoid the challenges of starting from scratch. The study began by reviewing 18 blockchain platforms and narrowing them down to 9 open-source options. It then used a combination of the Analytic Hierarchy Process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to evaluate the platforms. Expert opinions and a thorough literature review focused on four key criteria: Transparency and Traceability, Security and Data Integrity, Cost Efficiency, and User Experience and Accessibility. The AHP analysis showed that Transparency and Traceability were the most important factors, while the TOPSIS evaluation highlighted Hyperledger Sawtooth as the top platform, excelling in all areas. The study underscores the importance of a multi-criteria decision-making approach in selecting blockchain solutions for agriculture, showing how open-source platforms can enhance efficiency, ensure data integrity, and build trust with consumers. © 2024 IEEE.

In today's digital transformation era, technology has become an integral part of enterprises and organizations;this integration can only be efficacious when technology is aligned with business strategies. This business-IT alignment can be achieved via Enterprise Architecture (EA). Previous research extensively studied the benefits of EA adoption, frameworks, and processes, mostly from an information systems perspective. However, not an insignificant number of these frameworks and processes were criticized as being ambiguous, inconsistent, and infeasible to be used in the real world and EA theory construction. Hence, in this work, we will promote the general systems theory perspective to express EA more rigorously, holistically, and consistently. This study contributes to EA understanding by providing the initial grounds for modelling and constructing an EA theory from the systems theory perspective to making EA more conceivable and practical. © 2023 IEEE.

Maritime shipping plays a pivotal role in the global transportation system, providing safety and cost-effectiveness. However, it encounters numerous challenges, including port congestion, delivery delays, complex paperwork, unreliable reports on hazardous materials, and difficulties in tracing containers. To address these issues and mitigate risks associated with the transportation of hazardous goods, researchers have explored the implementation of blockchain technology in the maritime sector. Blockchain offers decentralization, transparency, and auditability of transactions, as well as the ability to trace and track cargo, particularly hazardous materials. Despite its potential, there is limited research available on the practical implementation of blockchain for hazardous material traceability. This research paper aims to investigate the application of blockchain technology in enhancing hazardous material traceability in seaports, contributing to the growing body of knowledge regarding blockchain's potential in this area and providing valuable insights for future research and practical implementations. Moreover, the paper suggests a preliminary framework for an optimized blockchain algorithm for hazardous material traceability. The main findings highlight the significant potential of blockchain technology in improving traceability of hazardous materials in seaports. Real-time tracking and monitoring of hazardous materials from origin to destination can be achieved through blockchain's distributed nature, reducing the risk of data manipulation or fraud. The immutability of blockchain records ensures the integrity and accuracy of critical data related to material composition, handling procedures, and safety certifications. Furthermore, blockchain's decentralized control allows for collaborative traceability in seaports, involving stakeholders such as port authorities, shipping companies, regulatory bodies, and manufacturers.
