The habits change. Formerly, the tailor made clothes according to the man's body. Today the man forms [models] his body according to the clothes pattern. In the industrial production the current is opposed. The standardized products multiply. The amount of the standardized products and the amount of components of each product increases. Work of production planning is bulkier. The cost needs to be calculated with more accuracy. The periods also demand more accuracy.
If the components of several production lines dispute same resources the periods should be calculated together [the whole production joins]. In the case of inclusion of new line everything should be calculated again. To foresee the cost of new line and the impact in the old lines, that is the viability of the new line or and which price does the new line viable, we needs to do the provisory calculations with all lines. This increases the cost of the calculation for the "pro-forma invoice". Fast calculations with software codified in MASM32 flat is described in http://oz.pro.br/wt/.
