Aircraft Assembly Line Thought

I have been studying the following simple case:

An aircraft assembly line is organized as a flow production process with a certain takt time. The total flow-time for assembly, painting and flight test is 25 days. The paint process takes 4-5 days, depending on the customer specific paint schema (due


The Dark Secret at the Heart of AI

No one really knows how the most advanced algorithms do what they do. That could be a problem.

Mass Sign and Effects

Since I met the Maxwell equations (oh God, half a century ago) I wonder if given the similarity between electrostatic and gravitational formels there would exist a non conservative, rotational field derived from masses in movement. As all masses have same sign and are attracted each other, this fiel

Equation For Comparing Flow Rates of Canal as a Function of Inflow Flow Rate?

Hello, I am conducting a research project which analyzes flow rates of open channels. In one particular portion of the project, I am analyzing an open channel that is receiving inflow from a separate source. Let us say for the purpose of this question that the flow rate of the water coming out from
