One variable input and biomass output as a single line curve based on EWT complex basic equation.
This production function is generated in real time and serves to illustrate the general production function relationship of output increasing with input but showing a diminishing marginal output response to input; the output rise is de-accelerating. The two remaining variables remain at constant values.
Several production surfaces generated using the EWT complex basic equation.
This low productivity surface is generated by plotting the values of T and W each over the range of 1 - 10 while E remains at 1.
This medium-low productivity surface is generated by plotting the values of T and W each over the range of 1 - 10 while E has been fixed at 5.
This medium productivity surface is generated by plotting the values of T and W each over the range of 1 - 10 while E has been fixed at 10.
This medium-high productivity surface is generated by plotting the values of T and W each over the range of 1 - 10 while E has been fixed at 20. However, in this case T and W become limiting so the peak condition is lower than could be attained is all variable inputs has risen to 20.
