The present article shows the integration of techniques for the early fault detection and diagnosis in industrial processes, in order to make recommendations to the operations staff in an industrial process and avoid safety incidents. The early fault detection and diagnosis provides assistance to the operations team in an industrial plant in order to make the right decisions during the process. This prevents small faults from escalating to critical situations where risks such as loss of human lives, damages to the environment or economic loss may exist. The article presents a prototype in a fluidized catalytic cracking unit.

The enterprise integration model called enterprise actor is a recent concept developed in the Industrial Automatics I + D group of Universidad del Cauca. Research work has been developed regarding this concept, and its results have allowed specific definitions and characteristics of the model. Future investigation is centered on the definition of a methodology that allows applying this model to manufacturing companies in order to assess the advantages that so far have been theoretically defined. The formalization of the methodology has led to a comparison between the current status of the enterprise actor model and multi-agent systems. This comparison has provided the investigation group with a new overview of certain elements that need to be modified, added or removed from the current structure of the proposed integration model. The present article shows the basic principles of the enterprise integration model, its current status and future projects that will allow its continuous development.

The present article describes the development of a project oriented towards physics, optics and electronics, and the implementation of an instrument to measure distance and speed. Its operation is based on a lateral movement interferometer with a two-sign optical configuration based on power supply. The measurements performed with the instrument show that distances can be measured in a 100 millimeter range according to its calibration and the implementation of the beam expander. In addition, the reader is presented with an instrument oriented to the application of alternative technologies that are not tied to modern productive processes such as robotic applications, a progress that is necessary to achieve greater technification and a sustainable development that allows the improvement of production conditions.

In order to obtain an integrated automation of production processes different aspects must be taken into account, such as the process itself, the company’s organizational structure, resources and business management. To reach an integrated system that manages the abovementioned aspects it is necessary to have behavior models that make it possible to demonstrate the knowledge of the business process and its supervision. The present article shows the results of the dynamic modeling of the product traceability process with Petri networks for WorkFlow (WF-Net).
