The telecommunication company aims to build a modular glass fiber network across

The telecommunication company aims to build a modular glass fiber network across 13 regions. Each region will have its own local network, and these will be interconnected via a main network. Local networks are designed using modular nodes, with various layouts containing 3, 4, 5, or 6 nodes. The main network, comprising star, circle, double circle, triple circle, or quadruple circle shapes, links these local networks. The project requires calculating system reliability for different network configurations and optimizing costs to achieve an overall reliability of 0.98 using Excel’s built-in functions.
