Simulation Environment Synchronizing Real Equipment for Manufacturing Cell

Abstract

Recently, manufacturing industries face various problems such as shorter product life cycle, more diversified customer needs. In this situation, it is very important to reduce lead-time of manufacturing system constructions. At the manufacturing system implementation stage, it is important to make and evaluate facility control programs for a manufacturing cell, such as ladder programs for programmable logical controllers (PLCs) rapidly. However, before the manufacturing systems are implemented, methods to evaluate the facility control programs for the equipment while mixing and synchronizing real equipment and virtual factory models on the computers have not been developed. This difficulty is caused by the complexity of the manufacturing system composed of a great variety of equipment, and stopped precise and rapid support of a manufacturing engineering process. In this paper, a manufacturing engineering environment (MEE) to support manufacturing engineering processes using simulation technologies is proposed. MEE consists of a manufacturing cell simulation environment (MCSE) and a distributed simulation environment (DSE). MCSE, which consists of a manufacturing cell simulator and a soft-wiring system, is emphatically proposed in detail. MCSE realizes making and evaluating facility control programs by using virtual factory models on computers before manufacturing systems are implemented.

Simulação a eventos discretos de uma via semaforizada com controle automatizado em tempo real

“…Estudos abordando a integração e comunicação entre simulação e sistema de controle automático existem desde o início da década de 90, como os trabalhos de Smith et al (1994), Wysk et al (1995), Davis et al (1996), Dougall (1998) e Auinger et al (1999). Mais recentes, trabalhos como os de Chwif (2002), Bullock et al(2004), Inukay (2007), Smith e Cho (2008), Bubicz e Sellitto (2009), Oliveira, Sabbadini e Chamowitz (2009), Koflanovich e Hartman (2010) e Rangel et al (2012) continuam investigando tal aplicação, e buscando compreender melhor os aspectos construtivos e operacionais.…”

Towards the Integrated Simulation and Programming of Palletizing Lines

“…Simulation and visual programming software tools can help to meet the requirements for modern palletizing units and assist both manufacturers and end users. Several software packages have been proposed for simulation of a machine component (Dong et al, 2002), for integrated simulation and parameters optimization of a manipulator (Kazi et al, 2002), and for high-level simulation of manufacturing systems (Inukai et al, 2007). Few tools, however, integrate simulation, programming and monitoring of a complete palletizing line.…”
