Resumen. En las últimas décadas se ha hecho indispensable el desarrollo de sistemas industriales que deben procesar gran cantidad de datos en breves periodos de tiempo. Estos sistemas se desarrollan poco en México, por un lado son complejos y especializados y por otro, deben ser claros y prácticos para que puedan ser utilizados en diversas áreas como es la de producción, ya que estos deben controlar la maquinaria en tiempo real y reflejar el estado de la misma en pantallas ubicadas a distancia, también, deben ser capaces de obtener información histórica para la toma de decisiones concretas en forma de reportes específicos según se requiera. En este artículo se presenta un modelo creado para desarrollar sistemas tipo SCADA el cual fue empleado en dos proyectos 1) trituramiento y pulverización y 2) pulimiento y limpieza, ambos de forma automatizada y de materia prima hecha a base de vidrio reciclado. El sistema se validó y los resultados obtenidos fueron satisfactorios, se espera que sirva de guía para desarrollos similares.Palabras clave. Sistemas industriales de control, sistemas SCADA, desarrollo de sistemas de información, sistemas de soporte para la toma de decisiones.Abstract. In the last decades, the development of industrial systems capable of processing large amounts of data in short time periods has become crucial. These systems are narrowly developed in Mexico due to their focused nature and complexity. They must be practical to use in diverse areas, such as production, where the system remotely controls and reports machine metrics in real time and reflect the status of it, on screens located on distance; they should also be capable of providing historical data when required. This article presents a model created to develop SCADA systems which was used in two projects 1) crushing and pulverization and 2) polishing and cleaning, both automated and raw material made from recycled glass. The system was validated and the results obtained were satisfactory, is expected to serve as a guideline for similar projects.Keywords. Industrial control systems, SCADA systems, development of information systems, support systems for decision making. IntroducciónEn las últimas décadas las empresas están reconociendo que trabajar con la mayor cantidad de información tanto histórica como actual, les ayuda a obtener mejores resultados, ya sea para realizar mejores planeaciones o para tomar mejores decisiones [5]. Existen diversos factores que están haciendo que las empresas sean mucho más competitivas, uno de ellos es la globalización, lo que conlleva al uso de la tecnología informática como recurso organizacional [6] y [11]. De hecho, aquellas empresas que tengan como Visión la de crecer, son aquellas que emplearán a la tecnología como una ventaja competitiva y, dependiendo del nivel de tecnología que apliquen solo se mantendrán o bien realmente podrán trabajar de manera global, convirtiéndose esta en un recurso de base operacional de la empresa [4].Los gerentes o responsables de la toma de decisiones, han comprendido que la...

To meet current challenges, manufacturing industries must develop precise designs for interactions of various components of production control systems, and in particular for behavior of the software controlling them. Several diagrammatic techniques, e.g., SDL, statecharts, and UML, have been utilized to represent the static and dynamic aspects of control systems. Still, a conceptual framework is lacking that would integrate components and allow assembly of applications from shared processes. This paper addresses the issue by providing schemata to be used in the conceptual modeling of production control systems. A flow-based specification that has been utilized in software engineering is proposed as a good vehicle in this area. The resulting description achieves uniformity by using a single flow system to represent all production system elements. The methodology is demonstrated by recasting the diagrams of two specific research projects in unified flow models.

This paper illustrates a case study of a PLC (Programmable Logical Controller) logic simulation in the car manufacturing industry. The case study is developed in order to simulate and verify the PLC control program for an automobile panel AS/RS. Because of increasing demand, the complexity of the supply system is rising in this industry. To cope with this problem, companies use AS (automated storage) and RS (retrieval system) systems, despite inherent logical complexities. Industrial automated processes use PLC code to control the AS/RS; however, control information and the control code (PLC code) are difficult to understand. Therefore, this paper suggests a PLC simulation environment, using 3D models and PLC code, which consists of real automobile manufacturing data. Data used in this simulation is based on 3D and logical models, using actual size and PLC signals, respectively. The environment resembles a real factory; users can verify and test the PLC code using the simulation prior to implementation of AS/RS. The developed simulation environment can be used to run AS/RS systems to reduce time and cost. INTRODUCTIONTo fulfill increasing customer demand for various requirements, small quantity batch production and JIT (Just in Time) systems have been introduced in modern industries. The production system information and logistics have to comprise a single body to introduce these systems and thus high-speed facilities and high-accuracy control are necessary. The AS/RS (Automated Storage and Retrieval System), a rapid logistic system in automated manufacturing systems, plays a significant role to carry out production of parts and allow flexibility in functional changes. An AS/RS is a combination of equipment and controls that handle, store, and retrieve materials as needed with precision, accuracy, and speed under a defined degree of automation. Systems vary from relatively simple, manually controlled order-picking machines operating in small storage structures to extremely large, computer-controlled storage/ retrieval systems totally integrated into a manufacturing and distribution process. The AS/RS is applied to increase production volume in automated manufacturing systems through automation of facility control and strengthening of stock control. Application of the technology of AS/RS is a kernel skill for the construction of automated logistics, FMS, and CIM. Systematical management of information is not easily realized in an AS/RS, because special control rules and communication code are utilized to control the AS/RS, which uses an exclusive controller (Han et al. 1987, Hausma et al. 1976).
