Four products (A-D) are made in a batch processing plant. The times (in hours) required for each piece of equipment for each product are shown in Table P3.15.

Using the information in Table P3.15, answer the following questions:

• Is this a jobshop or flowshop plant?
• Over a 600 h period (approximately 1 month), the required number of batches for products B and D is 25 and 10, respectively. 
• The demand for products A and C is such that twice as many batches of A compared to C are required. Determine how many batches of A can be manufactured if single product campaigns are used. In your calculations, you should use the exact cycle time expression for each product.
• Repeat Part (b) but use the limiting cycle time for each product.
• For a process with unlimited intermediate storage (uis process) and an equal number of batches for each product, determine the maximum number of batches for each product using a mixed product campaign (ABCDABCD… or ACBDACBD…, etc.) in a 600 h operating period.
