This paper presents a multicriteria nominal classification method derived from the concepts of PROMETHEE, which is then applied to problems characterized by minimum performance profiles (MMP) to determine categories. In order to illustrate the applicability of the proposal, this method is applied to classify relational attitudes in the context of IT outsourcing regarding an IT service contractor company...
The basic indicators of the life cycle of technology were analyzed and the generalized system for the evaluation of the life cycle phase is allocated. Indicators are considered as properties that technology must have to fit a certain stage of its existence. The existing approaches of technology development analysis were studied. The generalized classification, which is a list of indexes for the proper...

Consumers in this case would be to buy the product based on the aspects and criteria in accordance with their wishes. Consumers will buy these products not only look from one criterion alone, there are...
IPO (Initial Public Offerings) pricing is a systematic and complicated task that directly determines whether the capital market is able to function in a healthy way. As China's stock market goes through ups and downs, China Securities Regulatory Commission generally adopts a positive strategy. Therefore, to weaken the policy factors, 48 cases of IPO companies dated from January 2014 to February 2014...
The purpose of the paper is to design a comprehensive evaluation system for the Chinese pharmaceutical manufacturing industry from the stakeholders' respective, and then apply it to evaluate listed companies by using entropy weight method and building the grey cluster evaluation model. The final evaluation results provide a reference for the stakeholders. The system is conductive to promote and guide...
As a global innovation capital and industrial cluster representative, Silicon Valley affects the whole world for its scientific and technological innovation. Patent co-citation can be used as information carrier to identify the core technology patents and evaluate technical similarities between enterprises in industrial clusters. In this paper, we carry out industrial clusters analysis of Silicon...
Stock market dynamics is of great importance to researchers from diverse fields. Network Analysis of stock data can play an important role in the study of stock market. In this paper, network based data mining of stock market is done to identify crucial players.

This study focuses on how the cumulative excess returns (CER) of corporate bonds in the Japanese market respond to simultaneous publications of current net earnings and management’s net earnings forecast. The estimation results using a regression model generalizing the interaction of the current net earnings and management’s net earnings forecast show that the CER of corporate bonds is influenced...
This paper presents a user independent choice decentralized charging strategy to motivate electric vehicle (EV) charging loads to achieve load valley filling in household smart micro-grid. A personal tailor price method is put forward by the power company side to guide EV charging processes accompanied by the user participation. At the EV user side, the EV user select personal tailor price trade based...
Based on listed companies in our country, this article explores the impact of tight money on corporate financing constraints by using cash-cash flow sensitivity model. This study finds that firms in our country usually face financing constraints, tight-money policy aggravates corporate financing constraints through bank lending channel, and meanwhile, no-tight-money policy alleviates corporate financing...
The security situation of China's futures industry is currently in good condition on the whole, with strong industrial competitiveness and control force, as well as low external dependency. However, under the new normal, there still exist some problems, such as fewer trading varieties of futures, irrational investor structure and the slow internationalization process and so on. So we must accelerate...
A numerical prediction algorithm called addition-subtraction frequency (ASF) algorithm is presented in this paper to predict potential valley-point dates of stock market. In the paper, we use historical valley-point date data of Shanghai Security Exchange (SSE) Composite Index as the input of ASF algorithm. According to the Royal Swedish Academy of Sciences, the stock prediction in the next three...
In this paper, we investigate the estimation of crop biophysical properties from small footprint LiDAR waveforms inversion. Due to crop heterogeneity within the same agricultural field, a classification on similar waveform clusters is performed before inversion. A Look up table (LUT) approach was adapted then, to derive the height and LAI of maize and wheat crops. The LUT was generated using the Discrete...
The Detrending Moving Average (DMA) algorithm can be implemented to estimate the Shannon entropy of a long-range correlated sequence which will be shown to be of particular relevance for its significance in finance. The entropy is written as the sum of two terms corresponding respectively to power-law (ordered) and exponentially (disordered) distributed blocks (clusters). Interestingly, the behaviour...
