Study of modeling and simulation for a chemical production system
Article Abstract:
The purpose of this paper is to demonstrate the advantages that may be obtained through the use of simulation tools in the design of a production workshop and more specifically, in validating a structure for production and a logic for control in the field of chemical processes. Such simulation concerns a type of production which is totally different from manufacturing type, as the former are continuous processes that can be rendered discrete. After a rapid presentation of the various theoretical approaches to modeling and simulation tools that may be used in this field, we will describe the system to be designed and its characteristics. Then we will go on to the approach to modeling we have retained and the simulation carried out in order to study the system dynamically. Finally, we will present the results we reached and will draw some conclusions on the advantages and the limits of the study made. This study, which aims at designing and evaluating the performances of a production unit in an international class plant specializing in the production of liquid chemical products, was carried out with the help of the SIMAN-CINEMA (3.5) simulation generator and decision assistance tool widely used in the design and set up of manufacturing type production systems.

Modeling and simulation of a six-legged walking robot power system
Article Abstract:
Reliable models and simulation enhance design and optimization capabilities considerably for complex systems. This study is concerned with such issues for a six-legged rough terrain walking vehicle power system that includes the associated control systems. The power system of the vehicle can be divided into three broad categories: leg systems, mechanical transmission system, and the primary power source and energy storage system. Modeling techniques, detailed analytical models, and a comprehensive nonlinear digital simulation are developed for precise performance predictions, interaction studies, parametric studies, and to aid in the mechanical and control design process. Validation of the models is provided by several experiments performed on a prototype leg and the vehicle. The models and simulation predictions have resulted in a significant improvement in vehicle performance. (Reprinted by permission of the publisher.)
