Incorrect credit judgement causes huge financial losses. This work describes the use of an evolutionary-fuzzy system capable of classifying suspicious and non-suspicious credit card transactions. The paper starts with the details of the system used in this work. A series of experiments are described, showing that the complete system is capable of attaining good accuracy and intelligibility levels for real data. 1. INTRODUCTION Fraud is a big problem today. Looking at credit card transactions alone, with millions of purchases every month, it is simply not humanly possible to check every one. And when many purchases are made with stolen credit cards, this inevitably results in losses of significant sums. The only viable solution to problems...

...Evaluating Competitiveness Using Fuzzy Analytic Hierarchy Process - A Case Study of Chinese Airlines Abstract With the development of a national market economy, the Chinese aviation industry is now confronted with international competition. Therefore, it is necessary to research the competitive status of Chinese national aviation, as well as advice on how to enhance the competitiveness of the Chinese aviation industry. The main objective of this paper is to propose FAHP as an effective solution for resolving the uncertainty and imprecision in the evaluation of airlines’ competitiveness. In this paper, we review the research of industrial international aviation competitiveness at both home and abroad, discuss a theoretical framework for the study of aviation competitiveness, establish an index system with 5 first-order indicators and 17 second-order indicators, set up a Chinese aviation competitiveness model based on simple fuzzy numbers from the Fuzzy Analytic Hierarchy Process, and evaluate the competitiveness of 5 major Chinese airlines. The results show that this model and these indicators are scientific and practical, with a wide range of application prospects for the purpose of improving and increasing Chinese airline competitiveness in the international market. The effective approach presented in this paper is especially applicable when subjective judgments on performance ratings and attribute weights are not accessible or reliable, or when suitable decision makers...

...International Review of Business Research Papers Vol.2. No.4. December 2006, Pp. 39-50 eBusiness-Process-Personalization using Neuro-Fuzzy Adaptive Control for Interactive Systems Zunaira Munir1 , Nie Gui Hua2 , Adeel Talib3 and Mudassir Ilyas4 ‘Personalization’, which was earlier recognized as the 5th ‘P’ of e-marketing , is now becoming a strategic success factor in the present customer-centric e-business environment. This paper proposes two changes in the current structure of personalization efforts in ebusinesses. Firstly, a move towards business-process personalization instead of only website-content personalization and secondly use of an interactive adaptive scheme instead of the commonly employed algorithmic filtering approaches. These can be achieved by applying a neuro-intelligence model to web based real time interactive systems and by integrating it with converging internal and external e-business processes. This paper presents a framework, showing how it is possible to personalize e-business processes by adapting the interactive system to customer preferences. The proposed model applies Neuro-Fuzzy Adaptive Control for Interactive Systems (NFACIS) model to converging business processes to get the desired results. Field of Research: Marketing, e-business 1.

...Assignment- 2 Assignment- 2 Strategic Management Strategic Management Submitted by: Ridhi Mundra 13A1HP124 Submitted by: Ridhi Mundra 13A1HP124 Company: McDonalds The McDonalds Corporation is the largest hamburger fast food chain in the world. It serves around 68 million customers daily in 119 countries. The company’s headquarters is in USA. The company has expanded its business across the globe through franchisee and affiliations and company owned outlets. McDonald’s revenue is not just from sales of the fast food but also royalties and rents i.e the company has many sources of other incomes as well. The company very well understands the changing customers need and accordingly alters its menu. To enter the Indian market McDonalds completely changed its menu to suit the Indian taste buds and has been very successful. The company follows a low cost leadership strategy and thus is able to deliver a low cost happy meal. The company provides good quality fast food at very low prices that competitors find it very difficult to match. The company is able to deliver its products at low prices because firstly they have vertical integration for few of its raw materials plus they buy other ingredients in bulk which lets them take the advantage of economies of scale , secondly they employee people with just basic educational qualification as mostly everything is machine operated the art of cooking is not...

...Control Mechanism For Best Buy Joanne Forde MGT/330 March 7, 2011 Dorothy Galiger Control Mechanism For Best Buy An effective control system within any organization must provide detailed information that is both valuable in its measure and consistent in its delivery. Such qualities of a control system are essential for management to harness it for the greater good of the organization. Control systems must be a fluid expansion of the control aspect of the organization’s strategic planning. Best Buy is a good example of a company that utilizes control systems to assist in company operations. These controls are not without their negative consequences, but for the most part, they serve as a beneficial tool for the company in achieving its goals. Control systems specify standards of performance, monitor, and measure company performance, and use data collected to compare the company outcomes to internal standards. Controls also assist in making steps toward continued improvement by reinforcing successful techniques and revising the less successful ones. Best Buy uses four distinct types of controls to maintain and drive the success of their organization: Feed forward control, market control, financial control, and Bureaucratic control. Feed Forward Control is aimed toward preventing problems before they begin by setting standards in place to reduce company loss. For example, Best Buy offers customers a return policy, but only gives cash refund with a receipt or...

...International Journal of Scientific & Engineering Research Volume 2, Issue 5, May-2011 ISSN 2229-5518 1 Autonomous Room Air Cooler Using Fuzzy Logic Control System M. Abbas, M. Saleem Khan, Fareeha Zafar Abstract— This research paper describes the design and implementation of an autonomous room air cooler using fuzzy rule based control system. The rule base receives two crisp input values from temperature and humidity sensors, divides the universe of discourse into regions with each region containing two fuzzy variables, fires the rules, and gives the output singleton values corresponding to each output variable. Three defuzzifiers are used to control the actuators; cooler fan, water pump and room exhaust fan. The results obtained from the simulation were found correct according to the design model. This research work will increase the capability of fuzzy logic control systems in process automation with potential benefits. MATLAB-simulation is used to achieve the designed goal.

...Available online at www.sciencedirect.com ScienceDirect Transportation Research Procedia 5 (2015) 186 – 200 SIDT Scientific Seminar 2013 Measuring transport systems efficiency under uncertainty by fuzzy sets theory based Data Envelopment Analysis: theoretical and practical comparison with traditional DEA model Sara Braya, Leonardo Caggiania and Michele Ottomanellia* a DICATECh – Politecnico di Bari, via E. Orabona 4, Bari 70125, Italy Abstract In transportation management the measure of systems efficiency is a key issue in order to verify the performances and propose the best countermeasure to achieve the prefixed goals. Many efforts have been made in this field to provide satisfactory answer to this problem. One of the most used methodologies is the Data Envelopment Analysis (DEA) that has been in many fields. The DEA technique is a useful is non-parametric method that allow to handle many output and input at the same time. In many real world applications, input and output data cannot be precisely measured. Imprecision (or approximation) and vagueness may be originated from indirect measurements, model estimation, subjective interpretation, and expert judgment or available information from different sources. Therefore, methodologies that allow the analyst to explicitly deal with imprecise or approximate data are of great interest, especially in freight transport where available data as well as stakeholders’ behavior often suffer from vagueness or...

...Question 1 – Do you think that to truly be effective it is possible for an international firm to have a common control system for any single activity? I do not think that to truly be effective it is possible for an international firm to have a common control system for any single activity because of the variety of cultures, institutional environments and financial costs associated with doing business in different countries. As the book illustrates in Chapter 3 companies that operate globally must take into account the cultural differences of the employees they higher and how they respond to different forms of management and oversight. In addition different countries have different rules, regulations, and laws that might impact what may be accepted business standards. It would be important to implement a control system that adhere to what is acceptable in that environment. Finally, there are different financial costs associated with operating in different countries. Using manufacturing as an example, although a company’s strategic control may theoretically apply across all environments, the tactical and operational controls that are implemented will need to be modified based on the country the factory is located. Question 3 – Do people respond to control systems or control systems respond to people? I recognize up front that I’m not providing a definitive “yes” or “no” answer to the question as to whether or not people respond to control systems or control systems respond...

...Four major control systems Question 1: Managers are most likely to step across ethical and legal boundaries when the pressure to perform is great. Pressure can be healthy but companies that set high-performance targets and grant large rewards for achieving these must have strong control systems to ensure that people are not tempted to cross boundaries. What are the four important control systems? After analyzing the WorldCom case I was able to gather what four major control systems that were not implemented correctly and led to their downfall. Risk management is one of the control systems that are very important. Risk management was very ineffective in WorldCom. With a risk assessment strategy in place which usually takes place once a quarter or semi-annually, employees or unit managers won’t be able to intentionally hide potential problems which could be avoided by identifying them in a timely manner. Control Activities was also another major weakness at WorldCom. Lack of organizational Instructions, weak controls of financial data and blocking or denial of information all are control activities not performed at WorldCom. No internal handbook based on U.S. GAAP to guarantee consistent, continuous, and legally compliant handling of basic and complex types of accounting entries was ever used. With a CEO that only wanted to hit the numbers and did not accept financial reporting when the figures didn’t match his expectations, financial reporting was never reliable. Another...
