CBF has hired you to help determine why they are not able to produce the 1,000 boards per day.
1. What type of process flow structure is CBF using?
The company is using a batch shop process flow structure. CBF, Inc. bases its board fabrication process on the average job size or on its typical order. This means that the company proceeds with the manufacturing process in batches so as to meet the specific requirements per order. The typical contract that the company currently gets is 60 boards per order. However, due to persisting factory defects, they manufacture a total of 75 boards per batch in order to compensate for 20% of the boards that they typically reject during the process.
2. Diagram the process in a manner similar to exhibit 6.7.
According to the book, the diagram is an operation and route sheet that specifies operations and process routing for a particular part. It conveys such information as the type of equipment, tooling and operations required to complete the particular part.
The ?Setup Hr.? is derived from dividing the setup (minutes per job, as illustrated in exhibit 6.9) by 60 minutes. Likewise, the hourly capacity of each operation (Rate Pc. Hr.) is solved by dividing 60 minutes by the run (minutes per part, as shown in exhibit 6.9).
3. Analyze the capacity of the process.
The first thing to consider is the process of cleaning and coating of the boards. This particular process involves the set-up of the machines, the loading of the boards, and the actual cleaning and coating of the said boards by the machines.
From the computations above, it is clearly illustrated that there is a disparity between the loading of the boards ...
