Nowadays, internet of things (IoT) technology is considered as one of the key future technologies. The adoption of such technology is receiving quick attention from many industries as competitive pressures inspire them to move forward and invest. As technologies continue to advance, such as IoT, there is a vital need for an approach to identify its viability. This research proposes the adoption of IoT technology and the use of a simulation paradigm to capture the complexity of a system, offer reliable and continuous perceptions into its present and likely future state, and evaluate the economic feasibility of such adoption. A case study of one of the largest pharmacy retail chain is presented. IoT devices are suggested to be used to remotely monitor the failures of a geographically distributed system of refrigeration units. Multi-agents distributed system is proposed to simulate the operational behavior of the refrigerators and calculate the return of investment (ROI) of the proposed IoT implementation.

The adoption of the Internet of Things (IoT) and its related technologies has transformed the manufacturing industry and has significantly changed the traditional linear manufacturing supply chains into dynamic and interconnected systems. However, the lack of an approach to assess the economic feasibility and return uncertainties of an IoT system implementation, is blamed as the culprit for hindering its adoption rate. Using two distinctive case studies, this research investigates the use of distributed simulation of agent-based model (ABM) to address such gap in the literature. The first involves the economic feasibility of an IoT implementation in a very large retail warehouse facility, while the second case study proposes a framework able to generate and assess ideal or near-ideal manufacturing configurations and capabilities, and in establishing appropriate information messaging protocols between the various system components by using ABM in distributed simulation.

The retail market in Vietnam continues to grow with the entry of foreign retail brands and the strong rise of domestic businesses in expanding distribution networks and conquering consumer confidence. The appearance of more retail brands has created a fiercely competitive market. Based on the outcomes of previous research results on brand choice intention combined with a customer survey, the paper proposes an analytical framework and scales to examine the relationship of five elements including store image, price perception, risk perception, brand attitudes, brand awareness and retail brand choice intention with a case study of the Hanoi-based Circle K convenience store chain. These five elements are the precondition for retail businesses to develop their brands so as to attract customers.

The operation and maintenance of buildings has seen several advances in recent years. Multiple information and communication technology (ICT) solutions have been introduced to better manage building maintenance. However, maintenance practices in buildings remain less efficient and lead to significant energy waste. In this paper, a predictive maintenance framework based on machine learning techniques is proposed. This framework aims to provide guidelines to implement predictive maintenance for building installations. The framework is organised into five steps: data collection, data processing, model development, fault notification and model improvement. A sport facility was selected as a case study in this work to demonstrate the framework. Data were collected from different heating ventilation and air conditioning (HVAC) installations using Internet of Things (IoT) devices and a building automation system (BAS). Then, a deep learning model was used to predict failures. The case study showed the potential of this framework to predict failures. However, multiple obstacles and barriers were observed related to data availability and feedback collection. The overall results of this paper can help to provide guidelines for scientists and practitioners to implement predictive maintenance approaches in buildings.

The current pandemic situation has created many challenges for maintaining positive relationships between fast fashion retailers and their suppliers. In the proposed paper it is assumed that strong and ethical relationships may be beneficial for all supply chain members, especially in the era of global pandemic. Therefore, the aforementioned issues (fast fashion retailers’ ethical behavior towards suppliers) constituted the subject of the paper. Our knowledge about relationships between fast retail chains and their suppliers in the times of global pandemic is relatively week. Trying to fill the gap, this paper discussed relationships between fast fashion retail chains and their suppliers’ customers on the basis of literature review and case study research. Purpose: The aim of the paper was to indicate the scope of activities undertaken by retailers and addressed at suppliers by fast fashion retail chains in pandemic times. The following goals of descriptive and cognitive character were assumed in the paper: (a) Identification of the fast fashion retailers’ common behavior in the era of pandemic, and (b) indication of ethical practices applied by fast fashion retail chains which are beneficial for all retail chain members, based on the Inditex example. Methodology: Based on the theoretic deliberation of retail chain relationships with suppliers in the pandemic times, qualitative research was conducted to supplement the theoretical background. The purpose of this study was to identify how fast fashion retailers maintain relationships with their suppliers in supply chains. The conducted research enabled us to reveal answers to the following research questions: What are good practices of fast fashion retailers in terms of relationships with suppliers? Can socially responsible, trustworthy fast fashion retailers stay profitable in the Covid-19 pandemic? The theoretical deliberation was based on a critical literature review. The empirical part of the paper was based on case study research. The conducted research was descriptive in nature, conducted in order to describe a particular phenomenon within its context, and was not intended to provide conclusive evidence, but to have a better understanding of the problem. A descriptive intrinsic case study was the method applied in the research. Results: On the grounds of literature studies, as well as collected information, we can state that close and ethical cooperation with suppliers, based on socially responsible relationships, are becoming a more and more important part of the strategy for commercial chains. There are companies that use any legal measures to not fulfil their obligations as contractors and avoid paying for orders completed and in production. The descriptive case study research allowed us to observe, analyze, and report good practices of fast fashion retailers in terms of relationships with their suppliers based on the Inditex example. The theoretical contribution: On the grounds of the case study, we can state that during pandemic times fast fashion retail chains have focused on the development of relationships with suppliers, which means changing from transactional to relationship marketing in cooperation strategies. Practical implications (if applicable): The paper provided intellectual input into the managerial problem of how to develop mutual beneficiary relationships between fast retail chains and their suppliers. The study suggests that fast fashion retail chains have to take into consideration growing customer expectations, which regard their cooperation’s strategies toward suppliers.

The purpose of this paper is to analyze the integration of Information and Communication Technologies (ICT) in higher education for imparting easily accessible, affordable and quality higher education leading to the uplift of Malaysia. The focus of the paper is on the benefits that ICT integration in education can provide, right from breaking time and distance barriers to facilitating collaboration and knowledge sharing among geographically distributed students. ICT increases the flexibility of delivery of education so that learners can access knowledge anytime and anywhere. It can influence the way students are taught and how they learn as now the processes are learner driven and not by teachers. This in turn would better prepare the learners for lifelong learning as well as to contribute to the industry. We will also analyze if ICT does indeed improve or hinder the quality of learning among higher education students. This paper reports on the changing trends in use of ICTs for instruction in higher education institutions (HEIs) and discusses a mini-case study of how ICTs are being used by lecturers in one university in Malaysia.
