For the next post in the series, we will explore the concept of industrial systems, with a particular focus on soft systems. Soft systems are an integral part of modern industrial processes, particularly in complex environments where human factors, organizational structures, and non-quantifiable elements play significant roles in decision-making and optimization.

This post is the second part of the series that will explore the optimization concept, tailored for authors and researchers interested in submitting to Jurnal Optimasi Sistem Industri (JOSI). We will break down essential optimization techniques and terminologies, providing insights that can guide your research and manuscript preparation, helping you align with the scope and standards of JOSI.

In our previous post, we explored the fundamental aspects of optimization, focusing on the objective function, constraints, and the distinction between local and global optima. We will build on that foundation by introducing two powerful concepts: gradients and convexity. These ideas play a central role in many optimization problems, determining how efficiently and effectively we can find the optimal solution. Understanding these tools will help you approach optimization challenges with greater precision and confidence.
