3. The most cost-effective way to produce gasoline is to never interrupt the process because the constant, uninterrupted production of gasoline leads to the greatest efficiency. This type of production is known as a(n) production process.

Continuous

Explanation:

Continuous production process is the procedure where the manufacture of the products need the sequential performance of different processes on multiple machines receives the material for manufacturing by the closed channel.

This process is mostly used in the business of chemical and paper.

So, in this case, the most effective way to produce the gasoline is the kind of production which is referred as the continuous production process.
