At this big factory:
$3$ production lines:Line$_1$,Line$_2$,Line$_3$;
$10$ products: $p_1,p_2,p_3,p_4,p_5,p_6,p_7,p_8,p_9,p_10$;
Each production line can produce each of the products, but each product still is recommended to should be produced on certain special line;
the time of producing one of some product is invariable;
each product line runs all the time;
switch from producing one product to another on production line would waste extra time;
Now I receive many orders which record information as below:
enter image description here
Now I treat them as below:
- merge the orders which have the same product name and deadline;
- for deadline day, I range all the orders on the recommended lines;
- if the recommended lines are not enough then switch to other free lines;
- if all the lines on the current day are not enough, then switch to lines of the next day;
- if all the products were arranged on the current day and still some of lines are a little free, then these free lines would be arranged to produce products of next day(then next next day);
I have coded according to above steps but I still think maybe there is some system method for this problem; I guess maybe I should use linear programming, but I don't know how since lack of these experience;
so shall I get some advice for resolving this problem or some demo/examples materials for similar problems?
thanks a lot!

@MalayTheDynamo Are you suggesting they remake the table? Right now the non MathJax text matches the table's convention and isn't very hard to parse.

@MarkS. Not the table. The text. $textLine_1$ would be better than line_1. As would $p_1$.

But then it wouldn't match the table, is my point.
