Due to the rapid use of various applications, the information is collected from these applications are vague and improper but the crisp information is an important part of any object-oriented database in the current scenario. As an uncertainty orvagueness in any database is represented through the fuzzy techniques, an object-oriented database is very efficient in handling that kind of fuzziness...

Fuzzy set theory has been extensively applied to extend various database models and resulted in numerous contributions, mainly with respect to the popular relational model or to some related form of it. To satisfy the need of modeling complex objects with imprecision and uncertainty, recently many researches have been concentrated on fuzzy semantic (conceptual) data models. This paper reviews f...

This contribution presents a new approach, based on Fuzzy Prototypical Knowledge Discovery, to predict the maintainability of class diagrams done using the Unified Modelling Language (UML), which has great importance on the final quality of object-oriented information systems (OOIS). The prediction model is built from metrics values obtained at the early phases of OOIS life-cycle. We will start...

Tool wear state classification has good potential to play a critical role in ensuring the dimensional accuracy of the work piece and prevention of damage to cutting tool in machining process. During machining process, tool wear is an important factor which contributes to the variation of spindle motor current, speed, feed and depth of cut. In the present work, on-line tool wear state detecting ...

This paper deals with a method which enables to describe a system using both UML State Machine Diagrams and Fuzzy-DEVS (to describe uncertain data) then to perform its simulation using DEVS formalism. The goal of the paper is to simplify the modeling of DEVS models, and also to take into account possible uncertainties on the transitions between states, by using a language based on UML State Mac...

Penjadwalan mata kuliah merupakan kegiatan yang sangat penting sebagai awal dari proses belajar mengajar agar dapat terlaksana dengan teratur, baik bagi dosen maupun mahasiswa mengambil kuliah. Dalam penggambaran sistem ini menggunakan metode pendekatan berorientasi objek alat bantu pemodelan UML (Unified Modeling Language) dan pengembangan model prototipe acuan tahapan penelitian. Penelitian t...

Due to the many limitation and poor data handling in the existing relational database, the software professional and researchers moves towards the object-oriented database which has much better capability to handling the real and complex real world data i.e. clear and crisp data and also have the capability to perform some huge and complex queries in an effective manner. On the other hand, a ne...

As the education fees are becoming more expensive, more students apply for scholarships. Consequently, hundreds and even thousands of applications need to be handled by the sponsor. To solve the problems, some alternatives based on several attributes (criteria) need to be selected. In order to make a decision on such fuzzy problems, Fuzzy Multiple Attribute Decision Making (FMDAM) can be applie...

The complexity of real production systems implies more difficulties to make an efficient monitoring and especially fault diagnosis. We propose a new method supporting the operator to find the cause and the origin of a fault. To obtain a diagnosis aid system that is both reactive and easy to configure, we define a set of artificial intelligence tools using neuro-fuzzy techniques. The interest of...
