The present study is a new approach for finding the suitable maintenance practice with the help of fuzzy logic rule base system. It is a decision making tool which depends upon various condition of a machine .The success of any industry depend on its optimum manufacturing cost of product and for achieving the above said factor the maintenance practice should be efficient and effective .Fuzzy ba...

This paper highlights the importance of software maintenance, specifically the UML (Unified Modeling Language) diagrams, created and changed, especially during the tasks of analysis and design of software. The main idea of this paper is to formalize the software maintenance phase in order to motivate the maintenance documentation of these diagrams taking into account a knowledge base which repr...

The true value of domain-specific modeling is found not in a domain-specific modeling language (DSML) but rather in the models that are created using that DSML. Changes to a physical system can be modeled, and the resulting executable model then is a working version of the physical system. Unfortunately, if the model of the domain—or metamodel—is changed, all models that were defined using that...

Source Integration is one of the core problems in Data Warehousing. Two critical factors for the design and maintenance of applications requiring Source Integration, and in particular Data Warehouse applications, are conceptual modeling of the domain, and reasoning support over the conceptual representation. We present a novel approach to conceptual modeling for Source Integration, which allows...

In this paper we propose a simulation model combining two processes of different origin (the production process and the information flow of maintenance work-orders) in one model in order to investigate how the interaction between the processes affect the performance of the production system, as well as to define the optimization opportunities. The proposed approach aims to extend the capabiliti...

This paper explores the impact of the size of a staff of equally trained maintenance technicians on the productivity of a serial production line. First, we use the reliability and maintainability characteristics of the line to derive optimal preventive maintenance (PM) policies for each unit of equipment. Second, we use simulation modeling to evaluate the performance of the line assuming all re...
