Recipe Scheduling Information Dialog

This dialog is presented when you select Tasks } Recipe Scheduling Information from the main menu. It allows you to edit the scheduling information required at the recipe level.

Specification Choices / Comments

For the entire process file, you must specify:

a) the Available Annual Operating Time,

b) the Number of Campaigns per Year,

c) the Number of Batches Per Year (if set by user), and

d) the Recipe Cycle Time or the Recipe Cycle Time Slack.

Using the above information as well as all the scheduling information at the operation level and the procedure level, the program calculates the following scheduling outputs:

a) the Recipe Batch Time,

b) the Minimum Recipe Cycle Time,

c) the Maximum Number of Batches per Year,

d) the amount of Main Product produced per Year,

e) the Unit Procedure with Longest Duration in the recipe,

f) the Equipment with Longest Occupancy (the Scheduling Bottleneck Equipment) in the recipe,

g) the Utilized Annual Operating Time,

h) the Number of Batches Per Year (if calculated), and

i) the Recipe Cycle Time Slack (if the Recipe Cycle Time is specified) or the Recipe Cycle Time (if the Recipe Cycle Time Slack is specified).

In cases where equipment are shared and used across batches then the user may need the assistance of the Cycle Time Calculator in order to find the desirable cycle time. Clicking on the Cycle Time Calculator button will produce the Cycle Time Calculator Dialog which can calculate all the valid cycle time bounds.
