Hit Flip Inc. is a skateboard manufacturer that supplies skateboard decks to specialty skateboard stores. With skateboarding being the fastest growing sport among children 10-18 years, the company is experiencing demand that greatly exceeds capacity for these specialty boards. The process steps are given below: Specifically, the boards, or "decks", are purchased from an outside suppun.. deck and paints these using a lithography machine. The company has 5 patterns that are painted on the decks. The lithography machine requires a setup (to change from one pattern to another), so decks are processed in batches according to the pattern. After painting, the decks are loaded onto a pallet (a device to hold a batch of decks) and dried using an ultraviolet lamp. The pallet is not placed under the lamp until all decks in a batch have been painted. The lamp can dry up to 50 decks at one time. The activity times per deck are as follows: Sanding: 3 minutes per deck Painting: 20 minutes setup, and 2 minutes per deck Drying: 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) At what batch size will sanding and painting both be bottlenecks? ( 6 points)
