Final answer:
Transportation and logistics are key to connecting the production line to suppliers, offering efficient movement of goods and integration of technologies within a connected supply chain system.
Step-by-step explanation:
The connection between the production line and suppliers is essentially facilitated by transportation and logistics. Transportation is critical for moving raw materials to production sites and finished goods to the market. Having efficient transportation options like proximity to uncrowded freeways, rail, and water transport can greatly enhance cost-effectiveness.
Additionally, with transportation being so heavily reliant on petroleum, the evolution of technology and the adoption of policies to maintain supply chains during emergencies become crucial. Furthermore, labor rights and improved labor policies play an important role in supporting the supply chain, ensuring that it is sustainable and responsible.
