The reliability-redundancy allocation problem can be approached as a mixed-integer programming problem. It has been solved by using optimization techniques such as dynamic programming, integer programming, and mixed-integer nonlinear programming. On the other hand, a broad class of meta-heuristics has been developed for reliability-redundancy optimization. Recently, a new meta-heuristics called harmony search (HS) algorithm has emerged. HS was conceptualized using an analogy with music improvisation process where music players improvise the pitches of their instruments to obtain better harmony. This paper introduces a modified HS approach combined with an operator of differential evolution - a paradigm of evolutionary computation - to solve optimization problems in reliability engineering. In this context, an example of mixed integer programming in reliability-redundancy design of an over-speed protection system for a gas turbine is evaluated. In this application domain, HS was found to outperform the previously best-known solutions available. ©2009 IEEE.

We consider a supply chain, which consists of N stocking locations and one supplier. The locations may be coordinated through replenishment strategies and lateral transshipments, i.e., transfer of a product among locations at the same echelon level. The supplier has limited production capacity. Therefore, the total amount of product supplied to the N locations is limited in each time period. When total replenishment orders exceed total supply, not all locations will be able to attain their base stock values. Therefore, different allocation rules are considered to specify how the supplier rations its limited capacity among the locations. We team up the modeling flexibility of simulation with sample path optimization to address the multilocation transshipment problem. We solve the sample average approximation problem by random search and by gradient search. With this numerical approach, we can study problems with non-identical costs and correlated demand structures. ©2009 IEEE.

IEEE/PES Transmission and Distribution Conference and Exhibition: Asia and Pacific

作者： Rony Seto Wibowo Naoto Yorino Mehdi Eghbal Yoshifiimi Zoka Yutaka Sasaki Complex Systems Engineering Department Graduate School of Engineering Hiroshima University Higashihiroshima Japan

This paper proposes a method for solving congestion management problem by optimally allocating FACTS devices. The problem is approached by utilizing optimization method which optimizes generation and installation costs while satisfying voltage stability index. The main contribution of this paper is to provide pareto optimal solutions which describe previous objectives during congestion and after congestion removed. Moreover, the method is able to rank optimal location in relieving congestion, to describe feasibility of solutions and to show better solution in improving voltage stability. Therefore, it is valuable for decision maker in determining locations and sizes of devices which gaining the benefit. Due to the complexity of the problem, Multi Objective Particle Swarm Optimization (MOPSO) is utilized to optimize devices allocation as master sub-problem; Sequential Quadratic programming (SQP) is used to solve the operation sub-problem, and Point of Collapse method is applied to calculate load margin during contingency. The effectiveness of this technique is demonstrated in modified IEEE 14 bus system.

3rd International RuleML 2009 Challenge, Collocated with the 3rd International Symposium on Rules, Applications and Interoperability, RuleML 2009

作者： Yeh, Ching-Long Lin, Kuo-Chung Kuan, Meng-Jong Department of Computer Science and Engineering Tatung University Taipei 104 Taiwan Information Systems Business Division Tatung Co. Taipei 104 Taiwan Graduate Institute of Project Management Kainan University Taoyuan 33857 Taiwan

In respect of the frequent fraud cases of social insurance by government organizations, the inspection procedure usually relies on experts' experience for verification and experienced personnel in charge for checking. However, due to the heavy work load and the insufficiency of manpower and lack of experience, the ratio of miscarriages of justice is very high, leading to improper settlement of claims and the waste of social resources. In this paper, we employ rule technology to improve the above inefficiency. We employ a knowledge engineering methodology to analyze the problem and construct the knowledge model, including the domain schema and rules. We then implement the knowledge model along with the existing database applications. The benefits generated by the research are: (1) establishing a knowledge system with expertise reasoning to solve the review problems of massive cases, (2) significantly reducing the large labor cost and consumed time of the existing reviewing system, and (3) improving the application level of traditional database in the expert reasoning system.

This paper describes the design of a unified framework for a multilingual text-to-speech （TTS） synthesis engine-Crystal. The unified framework defines the common TTS modules for different languages and/or dialects. The interfaces between consecutive modules conform to Speech Synthesis Markup Language （SSML） specification for standardization, interoperability, multilinguality, and extensibility. Detailed module divisions and implementation technologies for the unified framework are introduced, together with possible extension for algorithm research and evaluation of TTS synthesis.

Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2009年第18期53卷 1466 - 1470页

Several events on university campuses in recent years have raised awareness about the importance of effective mass emergencies notification systems (MNS). These systems are developed to deliver critical information during life threatening events. Congress created a grant program specific for purchasing mass notification technology. When a mass notification system is in place an individual or group of individuals can send out prerecorded messages or customized messages to any or all of the system's various group lists. Message delivery can be sent using text messaging, e-mail, PDAs, sirens, flashing strobes, intercoms, outdoor emergency phones, computer screen displays, cell and landline phones, and live or recorded voice announcements. Schools, universities, medical buildings, cities, law enforcement, and military have embraced such systems. Any organization can use mass notification to better their emergency management. These systems can also be used to distribute non-emergency messages such as breaking news that is of interest to students or *** has been introduced in the U.S. House of Representatives to require colleges to immediately notify their students and employees when an emergency happens on campus. As recent incidents have demonstrated, minutes can mean the difference between life and death. Mass notification technology helps ensure that information is communicated, empowering students and employees so that they can take steps to protect themselves during a crisis. Students, parents, teachers, and college instructors have already embraced these *** University of Science and Technology (Missouri S&T) installed an MNS to notify the campus community of emergency information via phone, email, SMS Text, and instant messaging.

Interval-valued fuzzy relation-based clustering with its application to performance evaluation

Computers and Mathematics with Applications 2009年第5期57卷 841-849页

作者： Guh, Yuh-Yuan Yang, Miin-Shen Po, Rung-Wei Lee, E. Stanley Graduate School of Business Administration Chung Yuan Christian University Chung Li 32023 Taiwan Department of Applied Mathematics Chung Yuan Christian University Chung Li 32023 Taiwan Institute of Technology Management National Tsing Hua University Hsinchu 30013 Taiwan Department of Industrial and Manufacturing Systems Engineering Kansas State University Manhattan KS 66506 United States

A similarity relation with its partition tree has been applied in the performance evaluation area for obtaining an agglomerative hierarchical clustering. These fuzzy relation-based methods require a decision maker to perform pair-wise comparisons for the similarity among criteria as forming a fuzzy relation matrix. The approach is developed based on real membership values of fuzzy relations. However, interval-valued memberships may be better than real membership values to represent higher-order imprecision and vagueness for human perception. Thus, in this paper we would like to extend fuzzy relations to interval-valued fuzzy relations and then construct interval-valued similarity relations for performance evaluation. We first give some definitions for these interval-valued types of fuzzy relation, similarity relation and resolution form. We then construct an interval-valued fuzzy similarity relation into a hierarchical structure schema. It is shown that both of procedures and results for the partition tree derived from interval-valued and crisp-valued similarity relation matrices have some corresponding relationships and different merits. To demonstrate the usefulness of the proposed approach, performance evaluations for academic departments of higher education are considered by using actual engineering school data in Taiwan. © 2008 Elsevier Ltd.

In traditional visual secret sharing (VSS) scheme, the pixel expansion is a drawback which not only increases the transmission cost, but also distorts the recovered secret image. This paper proposes a visual secret sharing scheme which hides a secret into two share images without pixel expansion. It provides high quality of recovered secret image. The experimental results show the stacking result of share images in our scheme is smoother than others. Copyright © 2009 ACM.
