Simulation offers a quick, controllable and tunable approach for prototyping complex assembly processes in manufacturing environments. In order to improve the responsiveness of production system, this paper proposes a new approach based on data driven modeling and simulation methodology, it can automatically generate the simulation model of production system and realize rapid modification. The generated model also has high efficiency, readability and reusability. The approach is developed for an automotive assembly line. Through the modeling approach of IDEF1X, a data structure of simulation model was constructed, a model simulator was implemented in Arena by VBA program, and then a simulation model for target production system was built automatically through the attribute values in the data structure. The management and control process of assembly line is divided into different levels by hierarchical modeling approach, modeling element and control logic of simulation are separated. The case study of the automotive assembly line demonstrates the validity of data driven modeling and simulation methodology.

This paper proposes enhanced prediction and control design methods for improving traffic flow with human-driven and automated vehicles. To achieve accurate prediction for the entire time horizon, data-driven and model-based prediction methods were integrated. The goal of the integration was to accurately predict the outflow of the traffic network, which was selected as the highway section in this paper. The proposed novel prediction method was used in the optimal design for calculating controlled inflows on highway ramps. The goal of the design was to reach the maximum outflow of the traffic network, even against disturbances on uncontrolled inflows of the network. The control design leads to an optimization problem based on the min–max principle, i.e., the traffic outflow is considered to be maximized by controlled inflows and to be minimized by uncontrolled inflows. The effectiveness of the prediction and the control methods through simulation examples are illustrated, i.e., traffic outflow can be maximized by the control system under various uncontrolled inflow values.

Study Implementation

This paper presents a case study implementation of one of the Toyota Production System (TPS) tools, known as Standardized Work (SW), in an automotive assembly line in Malaysia. The main functions of SW are to design, develop, document and visualize a set of a manufacturing process with detail and proper study of it. SW is conducted to raise production consistency and quality of a produced product and the job performed. With the proper SW implementation, good results have been obtained from the increase in efficiency, productivity, quality and process stability of the operator’s performance. Thus, the findings are consistent with TPS philosophies which are waste elimination and continuous improvement in any manufacturing area.

In this paper a dynamic simulation methodology of systems is presented by using ADAMS/MATLAB co-simulation. This methodology allows simulation, development and validation of different control strategiesfor robotic manipulator models in a fast way. It provides a first stage into the design of robotic prototypes for researchers and professionals. Finally, the methodology was validated by constructing a simulation model of a double pendulum and by implementing a PD type control strategy.
