VIII A laser machine is used to process metal sheets based on customer orders. The inventory level of this metal went from 1.6 tons at the start of the week to 2.2 tons at the end of the week. During the same week, 5 tons of metal sheets were added to the inventory Determine the material efficiency of the system if the total weight of delivered orders was 3.3 tons during the week. If an additional processed is used, then 20 percent of waste can be reused similar to the new material. Calculate the material efficiency when this additional process is used Assuming the price of this metal is $5000 per ton and the processing cost per ton is $13000 for each ton of input, determine the efficiency of this production system based on cost. How different this way of calculation is compared the way material efficiency is calculated in question "a"? The "processing cost" can be attributed to the capital cost 30%, la bour cost 40%, and energy cost 20%. How this knowledge could influence our understanding of efficiency? a. b. c. d
