This paper presents the application of adaptive neuro-fuzzy inference systems (ANFIS), using Sugeno ANFIS to measure the quality management performance of public highway construction organization in Thailand. Attributes associated with Public Sector Management Quality Award (PMQA) criteria are considered as the input and output variables for the main-model and sub-models, respectively. The dependent variable is the quality management performance. Highway projects for the Thailand Department of Highway (DOH) have been used as data sources for this study. The result can be used to improve its quality as well as to achieve high performance organization.

The developing countries have lately experienced a surge in mobile phone adoption. New investment into the telecom sector has enabled network roll-out, and increasingly innovative business models have driven down network operation costs and customer acquisition & retention costs, enabling pricing to be lowered significantly (Samrajiva, 2009). The result is that people who, just a few years ago were unable to afford any form of telephone are now purchasing mobile phones and SIM cards and using them to make calls and send SMS. Given the dearth of fixed access networks, developing nations, especially those in South Asia, depend mobile phones to take their citizens online. All these new consumers are naturally creating increased demand for Internet capacity. At the same time, the demand for Internet access capacity is increasing because many South Asian countries (particularly India, and to a less extent others such as Sri Lanka) have been at the forefront of attracting a significant share of the booming market for business process outsourcing. While new consumer numbers are growing, tests performed by LIRNEasia in India, Bangladesh and Sri Lanka show that users get low value for money from their broadband connections when compared to North American counterparts. Using only data publically available, we could hypothesize that the poor performance of South Asian broadband in terms of throughput (upload speed, download speed), jitter, latency and other measurable dimensions is due to the lack of international capacity (as opposed to the local access network capacity or in-country back haul capacity). For example, we know that while the region has surging demand, the supply of international connectivity has not caught up to the demand (Telegeography, 2010). Therefore South Asian internet service providers end up paying significantly higher fees for international connectivity when compared even to their East Asian peers (Telegeography, 2009). We test our hypothesis using a broadband quality of service testing methodology developed jointly by LIRNEasia and the Indian Institute of Technology, Madras. The results confirm that international connectivity is indeed a significant choke point when accessing the Internet and negatively impacts the service quality of broadband. Individual countries or individual ISPs cannot do much in the immediate or near term to increase international leased line capacity and prices (due to relatively long lead times required to actually lay the cable, and the seemingly longer time some countries require to agree on the rules related to the consortia that participate in the cable). However, our testing provides data on a second choke point, one that is very much within the control of the ISPs. The points where two or more ISPs exchange traffic (network access points/NAPs, or Internet exchanges/IXPs) turn out to be choking points also. While ISPs in smaller/developing countries may not have control over international NAPs/peering

Quality Function Deployment (QFD) has been used earlier in the design of curriculum of courses and various other aspects of imparting higher education. In this paper, we have shown the use of this concept in designing and discussing business case studies in imparting management education. It is becoming increasingly difficult to get readymade case studies, which can satisfy the learning requirements of heterogeneous group of students in any MBA program. It is thus imperative that the instructors will have to make case studies on their own suitable to their own set of students with unique expectations for discussion in the classroom. The QFD process starts by asking the students about their overall expectations and the relative importance of each of the expectations on a scale. Various relationships between these expectations and the corresponding technical requirements to satisfy these expectations are then found. The interrelationships between these technical requirements are also determined. The entire information is shown in different parts of a matrix known as the QFD house of quality. The output of this matrix is a set of values suggesting which technical requirements are more important to be addressed in order to satisfy the requirements of students in a better way. In the first part of this paper, we discussed a case from a textbook authored by one of the authors of this paper, in a class of MBA students. Then, we interviewed a sample group of students to know the performance ratings of this case and the cases of our closest competitor (instructor) with respect to their various expectations. In the second part, we applied the QFD to find the technical requirements, which will help in satisfying the student’s expectations in a better way. In the last part of the paper, on the basis of these inputs, we designed a new case study and discussed the case with the same class of MBA students. Feedback from students was obtained to find the performance ratings of the new case subjected to quality function deployment. The performance rating of the new case was found to be higher on various parameters giving positive results of the QFD exercise.

We develop a new model of quality to capture the idea that even if a customer chooses to purchase a product, it may fail to deliver.' In this event, the customer may wish to choose some other product. We model this as a two stage game where firms first choose quality and then price. We find that in equilibrium, the high quality firm (the one with a higher probability of being able to deliver') will always make higher profits than the low quality one even if costs of quality are sharply increasing. Our work thus provides a reason for high quality niches to be inherently more profitable. The implications for welfare and equilibrium under free entry are also studied.

Failure Mode Effect Analysis (FMEA) is a powerful proactive technique developed to prevent product and process failures. FMEA (also known as the fish-bone or the Ishikawa technique after its originator) was first used by Japanese automobile manufacturers to plan their production systems on the shop floor (Pfeifer, et alt 1994). It is now gaining acceptance in other areas like logistics, quality control and even personnel management. FMEA in its traditional form. The author is presently a member of faculty at Indian Institute of Management, Bangalore is largely dependent on managerial judgment and uses minimal mathematics or computer time. Despite simplicity it is an elegant technique for ensuring process performance, likemany other management techniques originating from Japan, FMEA requires team-based thinking and a mutual belief in collective responsibility. The success of this method therefore rests largely upon the behavioural-motivational aspects of the people involved in the process. In this paper, I propose to provide an overview of FMEA as a management tool and at the same time suggest improvements for better effectiveness.
失效模式影响分析(FMEA)是一种强大的前瞻性技术，用于预防产品和过程失效。FMEA(也被称为鱼骨或石川技术，以其创始人命名)首先被日本汽车制造商用于在车间规划其生产系统(Pfeifer, et alt 1994)。如今，它在物流、质量控制甚至人事管理等其他领域也得到了认可。传统形式的FMEA。本文作者目前是位于班加罗尔的印度管理学院(Indian Institute of Management)的一名教员，主要依靠管理判断，很少使用数学或计算机时间。尽管它很简单，但它是一种确保过程性能的优雅技术，就像起源于日本的许多其他管理技术一样，FMEA需要基于团队的思维和对集体责任的共同信念。因此，这种方法的成功很大程度上取决于参与过程的人的行为动机方面。在本文中，我建议提供FMEA作为一种管理工具的概述，同时提出改进建议以提高有效性。

This paper is based on ISO 9000 which was conducted by making personal visits to plants located in Bangalore. It deals with:- The overall structure of ISO 9000 Quality Standard- Activities involved in implementing an ISO 9000 Quality Standard and the planning required in successfully implementing the programme.- Issues involved in implementation.- Distribution analysis of QS certificates awarded to Indian Companies up to October, 1993.The understanding, discussion and implementation of ISO 9000 has recently assumed lot of importance not only in our country but also in other parts of the world. Various reasons could be attributed to this. Some of them are:(1) Product/Service Quality has been identified as one of the important factors for becoming competitive.(2) Globalization in almost all types of activities is forcing many global players to insist on quality inputs irrespective of the source from which they are procured. In other words, a company which wishes to do business globally has to ensure quality performance with respect to their activities.(3) To gain entry into EC market many companies have been insisting on the interested party to demonstrate that they have a system which can ensure the quality of the product/service provided those who wanted to respond to the changes that are taking place had gone for some sort of quality certification such as ISO 9000.(4) As far as India is concerned, after liberalization, companies have realized that to do business, they have to be competitive, and to survive within the country and also to compete in the global market they have to improve their performance especially in the quality front. This development has forced many companies to go for quality certification.
