Question 1 1.1 1.2 Identify the 3 benefits long term planning, medium term planning and short term planning (9) In a 7 day week a machine works for 150 hours, its loading time. Change over's take an average of 15 hours and breakdowns an average of 10 hours every 7 days. On average the machine waits for material for 5 hours and when it runs, it averages 80% of its rated speed. 5% of what is run is defective. Calculate the OEE? (20) 1.3 Suppose a television producing factory produces three different models of television units, the plasma, the LED and the 3D. The plasma model can be assembled in 1.0 hours, the LED in 1.25 hours and the plasma in 1.75 hour. The assembly area in the factory has 650 staff hours of assembly time available each week. If demand for the plasma, the LED and the 3D is in the ratio 3:4:3, calculate the following: (12) 1.3.1 Time needed to assemble the units 1.3.2 Number of units produced per week 1.3.3 1.4 If the demand changes to a ratio of plasma, LED and 3D units of 2:1:3, what will the time needed to assemble the units be 1.3.4 Number of units produced per week A chocolate manufacturing company has a slab manufacturing line that operates 24 hours a day, 7 days a week. The records for a weeks production show the following lost production times:(9) Product changeovers 22 hours Preventative maintenance 14 hours No work scheduled 8 hours Quality checks 9 hours Shift change times 8 hours Breakdowns 21 hours Quality defects 20 hours Material shortages 9 hours Labour shortages 7 hours Waiting for chocolate 7 hours 1.4.1 Calculate utilisation 1.4.2 Calculate efficiency Question 1 1.1 1.2 Identify the 3 benefits long term planning, medium term planning and short term planning (9) In a 7 day week a machine works for 150 hours, its loading time.
