I'm learning linear programming's basic concepts. In following inequality:
$ \begin{align} \text{Minimize }c_1x_1 + c_2x_2 + \cdots+ c_nx_n \\ \\ \text{Subject to }a_{11}x_1 + a_{12}x_2 +\cdots+a_{1n}x_n & \geqslant b_1 \\ \\ a_{21}x_1 + a_{22}x_2 +\cdots+a_{2n}x_n & \geqslant b_2 \\ & {}\ \vdots\\ a_{m1}x_1 + a_{m2}x_2 +\cdots+a_{mn}x_n & \geqslant b_m \\ \\ x_1,x_2,\ldots,x_n & \geqslant 0 \end{align} $
My question is : Why we call $a_{ij}$ "technological coefficients" ? What is technology ? And why is it technological ? I don't know the meaning of "technological" in here.
Thanks in advance
