Application of Fuzzy Analytical Hierarchy Process based on Geometric Mean Method to Prioritize Social Capital Network Indicators

Abstract: Vietnam is striving to develop dynamically and overcome many human resource challenges. As the economy expands, the demand for jobs and human resource development has become increasingly critical. The pressures from reform and international integration are forcing many changes. New graduates must provide proof of their academic capabilities, while also actively developing their social capital to support their job search process. In fact, social capital is an essential capital for personal development as well as professional development of new graduates. This paper applies Fuzzy Analytical Hierarchy Process based on Geometric Mean Methodology to evaluate factors for measuring the social capital of graduates at Ho Chi Minh City Open University in Vietnam. The research results highlight the important role of social networks for graduates, in which a linking network is the most important, a bonding network is the second most important, and a bridging network is the third most important. In addition, the research shows that trust plays an even more important role than networks; and specific belief is more important than general belief.

Towards a Mechanism for Protecting Seller’s Interest of Cash on Delivery by using Smart Contract in Hyperledger

Abstract: In emerging economies, with the explosion of e-commerce, payment methods have increasingly enhanced security. However, Cash-on-Delivery (COD) payment method still prevails in cash-based economies. Although COD allows consumers to be more proactive in making payments, it still appears to be vulnerable by the appearance of a third party (shipping companies). In this paper, we proposed a payment system based on “smart contract” implemented on top of blockchain technology to minimize risks for parties. The platform consists of a set of rules that each party must follow including specific delivery time and place, cost of delivery, mortgage money; thereby, forcing parties to be responsible for their tasks in order to complete the contract. We also provided a detailed implementation to illustrate the efficiency of our model.

Calculating Weights of Social Capital Index Using Analytic Hierarchy Process

Abstract: This study aims at identifying and ranking social capital indicators in the measurement model for Vietnam context. The analytic hierarchy process is adopted to explore the relative importance of each dimension in the integrated social capital index. The opinions from the in- depth interviews with experts, scholars and practitioners in social capital theory in Vietnam are employed to calculate the indicators’ weights in the model. The empirical findings indicate the superior impact of trust to network in the integrated index. Moreover, bridging and bridging-link are found to be more important than bonding and bonding-link. The result implies the potential of leveraging this resource for the development of individuals and community.

Extended Fuzzy Analytical Hierarchy Process Approach in Determinants of Employees’ Competencies in the Fourth Industrial Revolution

Abstract: This paper explored the education factors and ranked their impacts on the employees’ competencies development in Vietnam. Factors contributing to the employees’ competencies in the Vietnamese context are proposed based on the literature review under the justification of experts’ interviews. Then, the extended fuzzy analytical hierarchy process (EFAHP) approach was used to prioritize the importance of the factors affecting the employees’ competency. The research finding confirmed the decisive role of teachers with the greatest weight of impact on the employees’ competency, though there was a shift of teacher’s role to that of facilitator in the Fourth Industrial Revolution education.

Using Fuzzy Logic to Develop Employees’ Competency Ranking Model

Abstract: This paper developed the employees’ competency model based on the literature review of both the United Kingdom (UK) and the United States of America (US) approaches. Furthermore, experts’ interview is applied to justify the model in the Vietnamese context. A competency model comprising of seven dimensions with ASK (Attitudes, Skills, and Knowledge) components at each dimension was constructed. Then, the fuzzy logic approach was used to prioritize the importance of the dimensions in the employees’ competency ranking model. It was found that critical thinking and problems solving was the first criterion expected by the employer in the Vietnamese labor market.

Dynamic pricing in industrial internet of things: Blockchain application for energy management in smart cities

Abstract: With the advent of advancements in the power sector, various new methods have been devised to meet modern society’s electricity needs. To cope with these large sets of electronic device’s current requirements, better energy distribution is needed. Smart Grid (SG) facilitates energy providers to distribute electricity efficiently to the user according to their particular requirements. Recent advancements enable SG to monitor, analyze, control and coordinate for the demand and supply of electricity efficiency and energy saving. SG also allows two-way real-time communication between utilities and customers using cloud and Fog enabled infrastructures. SG minimizes management and operations cost, electricity theft, electricity losses, and maximize user comfort by giving the user choice about their energy use. It also facilitates Renewable Energy Resources (RER) and electric vehicles. Blockchain is a promising technology, provides the necessary features to solve most of these issues. Current Issues include saving a large amount of data, deletion, tampering, and revision of data. It also eliminates the necessity of intermediaries. Inherent security, along with the distributed nature, makes it a perfect candidate for improving the overall services. The rules of the smart contract are automatically enforced upon execution. Smart contracts are enhanced in a way that per-unit price is calculated dynamically based upon RER and utilities generated energy units in the overall grid. The system is also automated in a way that electricity is transferred from one resident (or service) to another resident according to their requirements. The exchange of energy is done via a smart contract after checking the needs of each participant. Each participant defines their requirements at the time of the registration and can update these thresholds. The privacy protection scheme has higher security, shown by theoretical security analysis. The main contributions of our work are two-fold; Using smart contracts to automate the bidding process for transactions based upon supply and demand for energy in smart cities. Secondly, at the same time, using hyper ledger fabric and composer to leveraging Blockchain to uphold privacy, anonymity, and confidentiality at the same time giving the users ability to have dynamic pricing based on supply and demand.

Blockchain: How shipping industry is dealing with the ultimate technological leap

Abstract: Despite its historical resilience to innovation, several novel technologies (e.g. IoT, AIS data, and automation) have recently been introduced in the maritime sector: the majority of them represents incremental changes in respect to current practice. Nevertheless, a few of these novel solutions could represent radical game changers for the whole shipping business. Among the latter category, blockchain registers a particular role, given the possibility for smoothening administrative problems, providing new ways to achieve secure and frictionless transactions at a global level. Despite the importance of such innovation, most of the published studies have just focused on technical aspects, while the adoption and implementation processes are far to be clarified since there is not a clear understanding on the potential effects of blockchain on shipping and logistics actors, especially at local level. The proposed study aims at filling this gap, providing insights that might help to better understand: i) which are the actors that impact the most on the blockchain implementation (and related potential frictions), and ii) the difference among alternative initiatives currently present on the market. In order to achieve these twofold aim, the study uses a triangulation approach, mixing literature and media reports research with both web-based research on main initiative characteristics and expert opinions. The proposed study defines that regulators and public authorities might potentially represent the main barrier to the full implementation of the block chain technology, especially due to a missing market standard.
