This document describes an approach to support an automated generation of simulation models by use of already existing engineering data. The concept enables engineers to execute tests in parallel to the development of the control applications, using a physical model of the controlled system. The simulation model forms a virtual representation of the process plant that is still under construction at...
Product data management (PDM) system enables the management of the entire product lifecycle and related information about its design, its manufacturing and its in-service. The interest of using the object-oriented approach for modeling, specifying and implementing PDM systems is detailed. Then an implementation method is proposed in order to clarify the instantiation of UML diagrams into database...
In this research work, auto-generation of PLC ladder diagram program is explained. This work is carried out in real time operation of PLCs in the plant and simulation of the models in the PlcStudioreg. Involved modelling and simulation tasks are performed in PlcStudioreg which is research product of digital manufacturing system (DMS) team in Ajou University, consists of input/output model and graphics...
The research presented the supply chain operation model based on networked manufacturing. It employs the Object-oriented Petri Net(OPN) to analyze the process of supply chain. The model of each object who takes part in supply chain operation was designed and the synthetical model was presented. Then, some properties such as deadlock, overflow and conflict can be analyzed. In such supply chain operation,...
To tackle the problems associated with the field management of furniture production, a furniture production line simulation model was constructed. This model was implemented by employing United Model Language (UML) as the modeling tool and object-oriented software, EM-Plant, as the development platform. The simulation results were analyzed on the basis of the average processing time, machine utilization...
