I am interested in manufacturing economics - suppose I have to built an engine, I would like to learn a systematic approach to break down what the costs of building an engine would be and how I could eventually optimize the process. I am a complete beginner to this, and I would like to learn from a resource that is not math-heavy (but not totally void of it!) which prioritizes intuition and is generic enough to be applicable to many different scenarios (not just engines!).
The reason is I often hear people talk of fixed costs, variable costs, production costs, amortization, etc. I would just like to learn more about it to be able to "follow the discussion".
What good books could you recommend on this? I could not find any myself.
