b. For a wheelbarrow manufacturer, a process is needed which will produce the 'barrow' or material containing part. It can be made from a polymer or a metal. a. Describe with diagrams a suitable manufacturing process. Assume batch size to be 5000, repeated at variable intervals. (15 marks) Using this process: One barrow container is made every five minutes. The process has two operatives. Their wages are 10 per hour. The material costs for this part is 10 per unit. The fixed costs of this press are 3,000 per batch. A new machine is recommended by the production engineer, which will have fixed costs of 10,000 per batch. It needs only one operative. The machine produces one 'body' every two minutes. The material costs stay unchanged. Sketch a break-even graph making a comparison for these two processes. (7 marks) A new less expensive tool is proposed which will drop the fixed cost to 4,000 from start for process number two. However, the material it is made from is not as resilient as the original press tool. It will need a partial refurbishment every 5000 parts, which has a fixed cost of 2000. Sketch your understanding of what a new graph with this change would look like. (3 marks) c. Total: 25 marks
