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...
The growing complexity of products and processes in industrial production require new methods of processing technical information and searching for new IT solutions. Fast and adequate solutions can be made on the basis of extensive information and long-term experience. This is possible when the implementation of automated systems is seen as a general-functional process in which the emphasis is placed...
Cloud computing provides a means for developing economies to improve their global competitiveness. This is because it is a combination of infrastructure, technology innovation and technology readiness. Private organisations in the developing economy of context, believe there is a sizeable market to be served. The key challenge is to do this effectively at a price that is not only affordable but economically...
The primary objective of the marketing set-up is the customers' satisfaction. It is a measure of how products and services supplied by a company meet customer expectations. The companies that know customer expectation can deliver services/products of superior quality compared with those services provided by conceivable competitors, this is the key for the company success in the modern era. This paper...
An interval estimate is provided for the Herfindahl-Hirschman Index (HHI) when the knowledge about the market is incomplete, and we know just the largest market shares. Two rigorous bounds are provided for the HHI, without any further assumptions. Though the interval gets wider as the sum of the known market shares gets smaller, the estimate proves to be quite tight even when the fraction of the market...
The screening of new product projects is critically important for the survival of companies. Many approaches have been developed to deal with this screening process. In this paper, we introduce a kind of proportional 2-tuple fuzzy linguistic screening evaluation model and the so-called preference-preserving transformation based on canonical characteristic values. It is shown that this new screening...
The importance of considering the volumes to analyze stock prices movements can be considered as a well-accepted practice in the financial area. However, when we look at the scientific production in this field, we still cannot find a unified model that includes volume and price variations for stock assessment purposes. In this paper we present a computer model that could fulfill this gap, proposing...
Due to the growing of business market, there is an increasing need to enhance the connectivity of the market and provide a flexible tool which allows fast access. Mobile application can provide such type of accessibility. A mobile with the necessary applications connected with a wireless internet gives the user the required connectivity. Although hardware processing capabilities of the mobile might...
This paper adopted Altman's Z model to analyze Chinese listed companies' financial data which has been selected from the A stock market in China. The paper found that the Z score is unstable but the whole trend is better compared to the former years. Finally, the author has found some microcosmic problems.
It is well known that credit rating for corporations is very important to the development and stability of financial market. The current rating methods always just pay attention to the information of rated aim. Here the paper offers a novel idea to improve the quality of credit rating with consideration to incidence relation among corporations. In addition, when the credit level of one corporation...
Due to the variety and complexity of computer virus harm, there are few practical evaluation methods currently. The paper presents harms' definition and classification of the virus. Then representative first-level and second-level evaluation indexes are proposed. However, as these evaluation factors could hardly be assigned with definite values and the evaluation process is more suitable to be regarded...
Enterprise competition comes into cooperation from opposition with the accelerating process of global integration. In this context, the paper studies the connotation of enterprise cooperation and cooperation motivation in-depth, demonstrates the promoting effect from good partnership to enterprise performance clearly. After designing the evaluation index of enterprise performance strictly, it establishes...
To reduce the high failure rate of the ERP applications, the paper established a fuzzy evaluation model of enterprise's ERP applications based on the theory of BSC (Balanced Score Card). Took 12 listed companies for example, the paper tested and evaluated the efficiency averages of their before and after 2 year's ERP implementation. The results indicated that good effect has been obtained after implementing...
In order to get rid of the limit of traditional methods and provide a decision making reference for the supervision of securities organizations and the risk control of investors, A novel model based on SOM2W network (SOM with 2 winners self-organizing map) is proposed for assessment financial performance of the listed companies. In addition, a tabu-mapping method is proposed to avoid that the same...
This paper analyzes the defects of the present method of company order assessment, a superior membership function is brought forward to establish the element values in the fuzzy evaluation matrix, the rationality of the membership function is proved and an example with the fuzzy evaluation matrix built by this membership function is given. The company order evaluation index system using fuzzy comprehensive...
In this paper, we suggest efficient heuristics to solve a cooperative transportation planning problem that is motivated by a scenario found in the German food industry. After an appropriate decomposition of the entire problem into sub problems, we obtain a set of rich vehicle routing problems (VRP) including due dates for the delivery of the orders, capacity constraints and maximum operating time...
The variety and complexity of virus harm cause there is few practical evaluation methods currently. The paper first presents harms' definition and classification of the virus. Then representative first-level and second-level evaluation indexes are proposed. However, as these evaluation factors could hardly be assigned with definite values and somewhat have fuzziness, the paper constructs a fuzzy evaluation...
Evaluation of managerial performance is one of the most important problems in management science. Two stage relative efficiency model, a newly named analytical method, is presented here in order to evaluate managerial performance fairly. This method evaluates managerial performance by eliminating the influence of existing conditions. Empirical results show that managers in firms with relatively superior...
Most of modern systems for information retrieval, fusion and management have to deal more and more with information expressed quatitatively (by linguistic labels) since human reports are better and easier expressed in natural language than with numbers. In this paper, we propose to use Herrera-Martinez' 2-tuple linguistic representation model (i.e. equidistant linguistic labels with a numeric value...
An improved model based on Kohonen neural network, called self-organizing map neural network with two winners (SOM2W), is applied to assess stock companies in this paper. In addition, in order to improve the precision of solutions, tabu-mapping method is also used to avoid that the same output node is mapped by more than one input. The clustering analysis for the stock is also done by using SOM2W...
