• General Overview:
  • For an assembly line for car manufacturing, assume that there are three sequential assembly stages. Also, there is an 8-hour shift, its a continuous operation since there isnt a start-up stage phase.
    • Stage A
      • Installs internal upholstery into the car seats, dashboard, steering wheel, etc.
      • Can process 20 cars/hour
      • There is an initial set up time of 20 min when changing the car model or size
    • Stage B
      • External painting of the car body
      • Can process 20 cars/hour
      • Must be shut down for maintenance and cleaning for 30 mins after every 90 mins of operation
    • Stage C
      • Final finishing of the car in terms of accessories - rims, lights, etc.
      • Can process 18 cars/hour
      • More customization, but no setups
• Part B Questions:
  • Three models X, Y, Z
    • Setup is only required for changing the model type on Stage A
    • Consider an 8-hour shift per day and 6 day per week operation (Monday through Saturday), determine the batch sequence for the three models that will be processed through the week.
      • How many of each model can I produce during the week? Develop a sequence for how the models will be produced over the 6-day period.
        • Parameters:
          • Theres an equal number of batches produced for each model in the week. Therefore, the entire weeks output would be equally split across the three models.
          • Within a single day, we need to produce at least one batch of each model
          • You could have more than one batch of each model produced within in a day
      • What happens to Part B analysis if you have a fourth model, Model W, in the mix? How would the solution change to incorporate this additional model?
