MODELING & SIMULATION FOR WORKPLACES ANALYSIS IN THE LEATHER INDUSTRY, G. De Sensi, F. Longo, G. Mirabelli
In this paper the authors analyze some workplaces of a manufacturing plant devoted to support hand-crafted production of leather items. Workers’ satisfaction and safety have been improved by using ergonomic analysis together with modeling and simulation. A three dimensional environment (developed by using a simulation software package) recreates the real workplace. The software used is eM-Workplace (by Tecnomatix Technologies) that integrates some ergonomic methodologies for designing and analyzing manufacturing workplaces. Finally the research work presents an ergonomically designed workstation that allows to prevent workers’ wrong posture, reduce overload operations during the manufacturing process and give more flexibility to the system in terms of items mixture. This last aspect plays an important role for satisfying the more and more specific requirements of the final customers.
SIMULATION MODELING OF A MANUFACTURING VINYL FLOOR SYSTEM TO IMPROVE PRODUCTIVITY AND QUALITY, Gabriela Arana, Carolina Rodríguez, Isis Castillo, Francisco J. Ruiz-Sánchez
In this paper we present a simulation modeling analysis of a new production line in a vinyl floor factory. We introduce the model of the vinyl floor manufacturing process and we briefly describe the process and comment some of the main considerations taken durino its construction. We establish the parameters that indicate the efficiency of the line and the quality of the final product, and we determine their relation with three control variables. We analyze the performance of the system exposed to different operational conditions. Finally, we show some simulation results and offer some proposal to modify the configuration of the production line to improve its performance. This project was realized by the students as a part of the Industrial Projects course with full involvement of industry .
INVENTORY POLICIES COMPARISN IN A MANUFACTURING PLANT BY USING MODELING AND SIMULATION, D. Curcio, F. Longo, G. Mirabelli
This paper focuses on the model implementation of a real system, in particular a manufacturing system that produces high-pressure hydraulic hoses. The objective is to use the simulator, developed by using the discrete event simulation package eM-Plant, for testing four different inventory control policies. The results comparison allows to understand which policy performs better in terms of average on hand inventory keeping fixed the service level provided to customer. |
