return on investment

 Calculate return on investment by optimizing cross-section saw capacity

According to the 9-hour working system every day

Nine working hours per shift

1、Efficiency:

a) . manually push and lift the saw

i) According to the actual market investigation and calculation, each person can cut 3000 meters of material every day. 6ax3000m = 18000m

II) it needs 6 skilled sawing experts to complete.

b) . cross section saw is preferred

i) The output of each machine is more than 35 meters per minute, 35 meters x 540 minutes = 18900 meters, which can be completed by two ordinary marking workers.

II) save 4 workers, calculated as 150 yuan per person per day for skilled Sawers, 150 yuan x 350 days = 52500 yuan / year, 4ax52500 yuan = 210000 yuan / year

The maintenance cost of the machine will not exceed 10000 yuan a year, and the labor cost will be saved by 210000-10000 = 200000

2. Accuracy and yield

a) For the sake of efficiency and safety, workers will produce a little waste

i) Now, it is a piece wage. Instead of carefully measuring and calculating the length of wood, it is to calculate the output. It is difficult to complete the speed and accuracy manually at the same time

In terms of safety, the hardness of scar is high, and it is easy to splash wood blocks to hurt people during sawing, with a scar error of 5mm. The head and tail sawing is too small, small wood blocks are easy to pop up and splash and hurt people, and the head and tail are poor 5-t- so workers will

consider staying away from stuttering and head and tail sawing when sawing. Manual sawing specification error 5mm

III) on average, there will be 4500 pieces of wood at 18000 meters for 4m materials and 9000 heads and tails (9000 saw mouth x5mm = 45m wood).

IV) on average, 18000 saws will be cut at 18000 meters for each one meter of wood

18000 saw edge x5mm = 90m wood

5) On average, according to a piece of wood, 4 scabs are 8 saws

18000m 4 - 4m = 4500 pieces, 4500 pieces X8 saws = 36000 saws

36000 saw blade x5mm = 180m wood

VI) saved timber 45 + 90 + 180 = 315m

Calculation of sectional area 30x50mm 315x0.03x0.05 = 0.4725m3

VII). Based on 3800 yuan per cubic meter, 0.4725 cubic meters x 3800 yuan = 1795 yuan

VIII) 1795 yuan can be saved every day, and 350 days x 1795 yuan = 628250 yuan per year


3. Safety and management

a) The number of safety accidents depends on the management of each factory, and the money saved in this item

This item cannot be estimated and calculated by our company. In short, we also hope that everyone will have no safety industrial accidents.

b) The mood of workers may lead to the loss and waste of wood. What is the specific loss

Each factory is different. There are some uncontrollable factors, such as working time and delivery date, and workers' work and rest time.

c) Invest 200000-300000 yuan in a preferred saw, and the return is 200000 yuan of labor costMaterial 600000.

d) The investment cost of recycling the machine within one year is no problem at all.
