Which of the following are key features of KUKA's flexible manufacturing systems?

The key features of KUKA's flexible manufacturing systems center around modular design and adaptability, making option B the correct choice.

Modular design refers to the ability of the manufacturing system to be composed of separate, interchangeable modules that can be independently added, removed, or reconfigured based on changing production needs. This design approach enhances flexibility, allowing manufacturers to quickly adapt their production lines to new products or varying production volumes without needing complete overhauls.

Adaptability is crucial in modern manufacturing environments, particularly as market demands fluctuate and customization becomes more prevalent. KUKA's systems are developed to easily accommodate diverse product lines and different manufacturing processes, allowing for swift changes to the production setup to meet specific customer requirements or to take advantage of new manufacturing technologies.

In contrast to this, fixed design and compatibility issues imply rigidity in the setup that hinders flexibility, while scalability and complexity would suggest challenges in managing the systems rather than benefits. Additionally, cost-effectiveness and limited application do not align with the goal of flexible manufacturing systems, which seek to maximize operational efficiency and adaptability across various applications.
