Description
|
|
Available Time Per Day (Current and Revised)
|
The system displays the available time for each work day, as defined in Kanban Process Maintenance. If you revise the current value and save your changes, the system updates that record.
|
|
Number of Resources (Current and Revised)
|
The system displays the number of resources available to the process, as defined in Kanban Process Maintenance. If you revise the current value and save your changes, the system updates that record.
|
|
Total Time Available Per Day (Current and Revised)
|
The system displays the current available time for each work day multiplied by the number of resources, as defined in Kanban Process Maintenance. If you update the number of resources or the time available per day, the system calculates and displays the revised total.
|
|
Uptime Percent (Current and Revised)
|
The system displays the percentage of the available time for each work day that the process is actually producing, as defined in Kanban Process Maintenance. If you revise the current value and save your changes, the system updates that record.
|
|
Adjust Time Available per Day (Current and Revised)
|
These fields display on the Process Data tab only (not on the grid). They are directly associated with the Available Cycle and Setup Time Per Day field in the process grid.
• The Current value displays the value as it was when you entered the workbench. It is initially the same as the Available Cycle and Setup Time Per Day grid field. It updates to match the revised value of that field when you save your changes.
• The Revised value is the same as Available Cycle and Setup Time Per Day. Any changes automatically update Available Cycle and Setup Time Per Day.
|
|
Available Cycle and Setup Time Per Day
|
The system displays the result of:
Available Time Per Day (Revised) * Uptime Percent (Revised) * Number of Resources (Revised)
|
|
Total Cycle Time Per Day
|
The system displays the total of all individual cycle times multiplied by the daily demand for the items produced by this process. When you modify values in the process data grid, the system updates this field.
|
|
Total Fixed EPEI Setup Time Per Day
|
The system displays the daily total setup time for items that have EPEI Auto set to No in Kanban Master Maintenance.
|
|
Available Setup Time Per Day
|
The system displays the result of:
Total Time Available Per Day (Revised) – Total Cycle Time Per Day – Total Fixed EPEI Setup Time per Day
|
|
Total Setup Time Per Interval
|
The system displays the total of all individual setup times for the items produced by this process that have EPEI Auto set to Yes. When you modify values in the process data grid, the system updates this field.
|
|
Intervals per Day
|
This is the number of times all setups can be performed each day. The system displays the result of:
Available Setup Time Per Day / Total Setup Time Per Interval
|
|
EPEI (Current)
|
The system displays the process every-part-every interval (EPEI) value from Kanban Master Maintenance. This is the time interval during which all parts produced by this process can be made while still meeting demand. EPEI is expressed in the interval defined in Kanban Process Maintenance. For example, when you choose Days as the interval, an EPEI of 1 means that the process can produce each part every day.
|
|
Minimum Process EPEI (Current and Revised)
|
The system displays the minimum process EPEI defined in Kanban Process Maintenance. If you revise this value and save your changes, the system updates that record.
|
|
EPEI (Calculated)
|
The system displays the EPEI value initially calculated by the workbench. If the value is negative, an error message displays.
|
|
EPEI (Revised)
|
The system displays the updated EPEI value. If the calculated EPEI is less than the value of Minimum Process EPEI (Revised), the system sets EPEI (Revised) to that value.
|
|
Lead Time Method (Current and Revised)
|
The system displays the process item lead time calculation method defined in Kanban Process Maintenance. If you revise this field, the system updates the Variable Lead Time field in the Sizing Data grid based on the new method. When you save your changes, the Kanban Process Maintenance record is updated. Valid values are:
• Variable. Default the value of Lead Time to Replenishment Time (Revised). Replenishment Time (Revised) cannot be updated.
• Fixed. Default the value of Replenishment Time (Current) to Replenishment Time (Revised).
|
|
Item Count
|
The system displays the number of items produced by this process, as defined in Kanban Master Maintenance or Kanban Process Maintenance.
|
|
Total Item Volume per Day
|
The system displays the total demand quantity of all the items produced by the process. This is calculated as the sum of the values in the Daily Demand Total column in the process item data grid.
|
|
Takt Time per Unit
|
The system displays the takt time for this process. Takt time is the time in which the process must produce one unit in order to match the rate of demand. It is calculated as:
Available Cycle and Setup Time per Day / Total Item Volume per Day
|
|
Pitch Time
|
The system displays the Pitch Interval value specified in Kanban Process Maintenance.
|
|
Pitch Quantity and UM
|
The system displays the pitch quantity and unit of measure specified in Kanban Process Maintenance. If an individual item is defined in a different UM, the conversion factor displays in the last column of the process item data grid.
|
|
Process Function
|
The system displays the process function specified in Kanban Process Maintenance. Processes can be defined as standard, pacemaker, or FIFO processes.
|
|
Load Limit Percent
|
The system displays the load limit specified in Kanban Process Maintenance. If you revise the current value and save your changes, the system updates that record.
|
|
Load Limit Time Per Day
|
The system displays the total time represented by the specified load limit percent, calculated as:
(Total Cycle Time Per Day + Available Setup Time Per Day) * Load Limit Percent
|
|
Current Load Percent
|
The system displays the percentage of total time available represented by the time required to produce this process item. It is calculated as:
Current Load Time / Total Time Available Per Day (Current)
|
|
Current Load Time Per Day
|
The system displays the total amount of time needed each day to set up and run the current daily demand for this process or for all items in the process. If this is greater than the value of Load Limit Time or Total Time Available Per Day, the system displays a warning message.
If either Order Quantity (Revised) in the sizing data grid or EPEI (Revised) is 0, the system uses 0 in the Current Load Time calculation.
|
|
Days Per Week
|
The system displays the number of days in a standard work week. These are days with any number of hours assigned to at least one shift in Process Calendar Maintenance.
|
|
Number of Changeovers Per Week
|
The system displays the number of times the process can be set up each week, calculated as:
(SUM (Revised Item EPEI * Daily Demand / Revised Order Quantity)) * Days Per Week / Revised Process EPEI
|
|
Changeover Hours Per Week
|
The system displays the total time required for setup each week, calculated as:
(SUM (Item Setup Time * Daily Demand / Revised Order Quantity)) * Days Per Week
|
|
Percent Changeover in Operating Cycle
|
The system displays the percentage of total load time represented by changeover time, calculated as:
SUM (Revised EPEI for process / Revised EPEI for item) * Setup Time in seconds / (Total Time Available Per Day in seconds * Revised EPEI for process)
|
