Web Application Development for Industrial Engineering

For decades, our discipline has focused on optimizing time, motion, and physical resources within production processes. However, in the context of Industry 4.0, efficiency is no longer measured solely on the production floor, but also by the speed, quality, and accuracy with which information flows throughout the organization. Today, an industrial engineer who doesn't understand the architecture of the data generated by their processes is, to some extent, operating blindly.

This book stems from a need observed both in university classrooms and in the production sector: to bridge the gap between process management and the development of technological solutions. In many cases, commercial software solutions are rigid or excessively expensive, while traditional spreadsheets end up becoming islands of information that are difficult to maintain and prone to error. Between these two extremes lies a space where engineers, with the right tools, can design and build their own digital solutions—agile, scalable, and aligned with the logic of the processes they manage.

This book is not a computer science manual aimed at programmers. It is, rather, a roadmap for industrial engineers who want to understand how processes can be transformed into information systems. Throughout these pages, the reader will not only learn the syntax of languages ​​like PHP or how to construct SQL queries, but will also learn to model operational reality within a digital structure, connecting processes, data, and decisions.

The central case study of this work, the SSOMA management system of Minera ZET, was not chosen at random. It represents an industrial environment where information management is critical. In these contexts, proper data management not only impacts operational efficiency, but also the safety of people and the sustainability of operations.

My goal with this text is to offer students and professionals a different perspective on the role of technology in industrial engineering. Rather than relying exclusively on external tools, engineers can develop the ability to transform manual processes into structured and robust information systems. Technology should not be a black box, but rather a space where industrial engineering projects its analytical capacity, creativity, and vision of continuous improvement.

I invite you to explore this path with curiosity, discipline, and a critical mind. In the world of digital transformation, code becomes one of the most powerful tools an engineer can use to understand, improve, and transform industry processes.
