Consider the problem of batch scheduling two products (A, B). The number of batches of B required

Question:

Consider the problem of batch scheduling two products (A, B). The number of batches of B required in a given time is twice the number of batches of A. One possible scheduling plan is shown in the Gantt chart in Figure P3.20, which shows the sequence BBABBABBA…. Using the information in Figure P3.20, answer the following questions:Mixer Reactor Crystallizer Separator 1 B 0 B B B T B B 1 A B B 4 6 8 10 Figure P3.20 Gantt Chart for Problem

  • How many batches of A and B can be produced (using the sequence BBABBABBA…) in a 600 h period?
  • How many batches of A and B can be produced in a 600 h period, if single product campaigns are used? (Remember, it is still necessary to produce twice the number of batches of B compared to A.)
  • If the desired yearly production volume of product B is 500 m and the plant operates for 7200 h/y, how much product storage for product B is required if a constant supply of B is to be maintained and single product campaigns are used as described in Part (b)?
  • Is this a jobshop or flowshop process?
