In Akhwan Company, operations director Mr Tamad recently realized there had been an increase in products failing during the final quality checks. These checks were carried out in the QC (quality control) laboratory, which tested finished goods products before being released for sale. The product failure rate had risen from 1% to 4% in two years' time which meant an increase of hundreds of items of output a month which were not sold to Akhwan's customers. The failed products had no value to the company once they had failed QC as the rework costs were not economic. Because the increase was gradual, it took a while for Mr Tamad to realize that the failure rate had risen. A thorough review of the main production operation revealed nothing that might explain the increased failure and so attention was focused on the QC laboratory. For some years, the QC laboratory at Ikhwan, managed by Ramly, had been marginalized in the company, with its two staff working in a remote…arrow_forwarddo fastarrow_forward

Assume the building lifetime is 60 years, AC-2 can save 300kWh/year than AC-1. The currency inflation rate is 3%. The electricity cost is $0.8/kWh at year-1 with an annual growth rate of 5%.
