The purpose of this paper is to introduce a quantitative method for assisting contractors to select appropriate projects for bidding by considering multiple attributes and integrating decision group member opinions.

The fuzzy technique for order preference by similarity to ideal solution (TOPSIS) method is used to help contractors make decision on project selection and the linguistic terms are defined for representing the triangular fuzzy numbers for ratings of alternatives and weights of criteria.

The selection of appropriate projects for bidding is a multiple attribute group decision‐making exercise. In a real decision process, there are many uncertainties and ambiguities, and time limitations mean that decision makers cannot always make precise judgments. The numerical example demonstrates that the fuzzy TOPSIS approach can be used to simulate the decision process in project selection, and the results provide contractors with valuable insight into the project selection problem.

Selecting appropriate projects for bidding is to use a contractor's limited resources more efficiently and increase the probability of winning contracts. Therefore, there is a need for a quantitative method to help contractors make better decision on project selection. That leads to the formulation of this paper. The fuzzy TOPSIS method can assist contractors to make better decisions in bidding.

The purpose of this paper is to summarize the advances in grey system theory research and various application achievements in science and engineering. At the same time, it commemorates the 40th anniversary of the birth of grey system theory and the 10th anniversary of Grey Systems–Theory and Application.

Firstly, the innovations of theoretical research in grey system theory were summarized and some of the widely recognized new results are briefly described. By searching and combing the research results of grey system theory in China national knowledge infrastructure (CNKI) database and Web of Science by Institute for Scientific Information (ISI), this paper shows the rapid development trend of grey system theory in the past 40 years, and the successful applications of grey system theory in the fields of social sciences, natural sciences and engineering technologies.

More than 227 thousands literature were found by input 10 phrases such as grey system, grey number and sequence operator etc. in CNKI database. After entering the new century, the number of grey system papers included in CNKI database is increasing rapidly. Since 2008, more than 10 thousands papers have been included per year and more than 15 thousands papers have been included per year since 2014. Grey system method and model are widely used in physics, chemistry, biology and other fields of natural science, as well as transportation, electric power, machinery and other fields of engineering technology, and a large number of valuable results have been achieved.

It can be seen that the grey system theory plays an important role in promoting China’s scientific and technological progress, innovation and development and high-level talent training from tens of thousands of literatures marked with important national science and technology projects and a large number of grey system literatures published by China’s double first-class universities and double first-class discipline construction universities.

Both innovations of theoretical research and practical application play important role in the growth of new theory. The innovations of theoretical research provide methods and tools for practical application, which is conducive to improve application efficiency and broaden application fields. A large number of practical applications needs have become the source of theoretical innovation and the solid background for the birth of theoretical innovation achievements.

The purpose of this paper is to investigate service quality of e-commerce Websites in online platform and their contribution on e-business promotion.

The online survey was performed on a survey portal provided by Nepal Telecom in Nepal.

The findings of this study suggest that information quality and online service quality were the key determinants for user satisfaction and sustainability of e-commerce technology.

Research opportunities of web services and e-commerce area are fruitful and important for both academics and practitioners.

The findings on online service quality of e-commerce technology will be useful for current management practice such as making business policies and strategies and sharing information to managers and organization leaders. This study can be used for e-commerce Website operators wishing to enhance the competitiveness of their Websites in the highly competitive online market.

E-commerce is considered an excellent alternative for individuals and companies to reach new customers. Service quality delivery through Internet is an essential strategy to success, more important than price and web presence. The e-commerce Website has been identified as having a significant impact on business activities in solving the geographical problem. A number of performance problems have been observed for e-commerce Websites, and much work has gone into characterizing the performance of web-servers and Internet applications.

In the past few decades, relationship management (RM) theory and RM strategies in business-to-business (B2B) contexts have evolved tremendously, driven by constant innovation. Hence, the purpose of this study is to understand the trends and evolution of RM and relationship quality (RQ) in B2B contexts and empirical insights on RM and RQ in B2B, which in turn would provide insights into trends and future research directions.

Grounded on the industrial marketing and purchasing group, this study adopts a critical systematic literature review to provide a comprehensive analysis of the past, current and future trends in empirical research insights of RM and RQ in B2B markets.

This study provides some novel insights into RM in B2B context by using a multidimensional approach to RM and RQ and analyzing prior marketing research from three perspectives: the evolution of RM and RQ in B2B context; prior empirical research; and practical business insights. Overall, these perspectives inform the development of an evolving side of RQ in B2B contexts, leading to some predictions regarding the future of RM in B2B markets.

The exploratory results of this study shed light on the key factors that drive RQ and the importance of RM in B2B markets in the digital age where customers still long for human interaction regardless of the prevalence of advanced technology.

In the wake of advanced technologies and particularly, B2B companies had to turn to virtual platforms and embrace digital transformation to establish and manage their customer relationships. Yet, managing relationships via digital channels has its own challenges for both B2B practitioners and scholars. This indicates that there is still a huge need for attuned RM strategies that align with the changing environments – mainly driven by technological advancement – in B2B markets.
