We propose a novel approach to improve prediction accuracy of grey power models including GM(1,1) and grey Verhulst model through optimization of the initial condition and model parameters in this paper. And we propose a modified grey Verhulst model. The new initial condition consists of the first item and the last item of a sequence generated from applying the first-order accumulative generati...

The vast majority of research output is grey; white (peer reviewed scholarly publications) forms a minor proportion. Historically, grey material was generated and used within an organisation. However, in recent years some researchrelevant grey material is being made openly available. Among grey outputs, research datasets are the largest proportion by volume and increasingly these are being made...

In western Canada, Eastern Grey Squirrels (Sciurus carolinensis) were introduced to Stanley Park in the city of Vancouver, British Columbia, shortly before 1914. The three to four pairs of introduced Eastern Grey Squirrels came from eastern Canada (Robinson and Cowan 1954). In the early 1980s, Eastern Grey Squirrels colonized the rest of the city of Vancouver, including many of its urban parks....

According to the qualitative safety evaluation index system of electric power communication network, it is easy to occur in the scoring problems, we put forward a kind of expert evaluation data by correlation degree, solve the problem of qualitative index difference. The method based on Relative Grey Relational Analysis on safety evaluation data, the establishment of expert evaluation of the re...

In the modern highly competitive marketplace and global market environment, product quality improvements that abridge development time and reduce the production costs are effective methods for promoting the business competitiveness of a product in shorter lifecycles. Since the design process is the best time to control such parameters, systematically designing the processes to develop a product...

Decision makers sometimes tend to express their preferences in intuitionistic fuzzy form. Based on evidence theory and grey relational analysis (GRA) technique, this paper aims at investigating multiple attribute decision making problems, in which both attribute values and weight values take the form of intuitionistic fuzzy numbers (IFNs). To this end, each intuitionistic fuzzy evaluation ratin...

Supply chain risk evaluation is a multi-criteria decision making problem under fuzzy environments. To tackle the problem, this paper firstly identifies and discusses some of the important and critical decision criteria and constructs the evaluation indicator framework. Then this paper presents a modified grey relational analysis method based on the concepts of ideal and anti-ideal points. In th...
