The activity times per deck are as follows: Sanding: 3 minutes per deck Painting: 20 minutes setup, and 2 minutes per deck Trvina: 30 minutes for the batch regardless of the batch size 2. Assume the following average inventory in sanding, the buffer, painting, and drying: Sanding: 1 batch Buffer: 2 batches Painting: 1 batch Drying: 1 batch What is the average flow time from the start of sanding until the decks leave the drying area with a batch size of 50 decks? Assume that the process is running at its capacity. ( 6 points) 3. At what batch size will sanding and painting both be bottlenecks? ( 6 points)
