Sep 23, 2011· Let's calculate the line efficiency of one production line. 48 operations worked in a line for 8 hours. They produced 160 garments and SAM of the garment is 44.25 minutes. Here, Total minutes produced = (160 x 44.25) = 7080 minutes. Total minutes attended = (48 operator x 8 hours x 60) = 23040 minutes. Effiicnecy% = (7080 x100)/23040 % = 30.729%.
Feb 15, 2019· To calculate your company's labor productivity, you would divide 80,000 by 1,500, which equals 53. This means that your company generates $53 per hour of work. You could also look at labor productivity in terms of individual employee contribution. In this case, instead of using hours as the input, you would use number of employees.
Jul 12, 2018· System Efficiency Applications. Several building systems can reduce energy consumption through improved controls, thermal exchanges, and multi-systems integration.While these measures may be easier to apply to new construction and major renovations, the majority of savings potential lies in changes to existing buildings.
Fuel quality affects construction equipment fuel efficiency. To enhance the durability of your investment: Buy fuel from a reputable source. Store it in a clean, well-maintained place, protected from dust and moisture. Use a recommended filtration unit with quality filters for refueling machines. Instigate a regular sampling programme of ...
Studies have shown 5 – 15% fuel efficiency gains at 75% power and 15 – 30% efficiency gains at 50% power. Running in this mode whenever possible reduces engine speed and can cut fuel usage by up to 22%, depending on machine and application. Too much or too little horsepower can drastically affect fuel efficiency.
