Define the parameters of calculation profiles for the kanban calculation.
In this step, you define the parameters and requirement smoothing procedures for kanban calculation profiles.
You can optimize the sizing of control cycles, by selecting a calculation profile in each control cycle. You can run the kanban calculation for the control cycle, to propose the number of containers or the quantity per container, based on the parameters defined in your calculation profile.
You define the following parameters in the calculation profile:
- Calculation Type
- The calculation type controls whether the number of kanban containers or the quantity per kanban container is to be calculated.
- Safety Factor
- The safety factor is used to cater proportionately for requirement fluctuations. It is multiplied by the result of the kanban calculation formula.
- Calculation Constant
- Depending on how Kanban is used in production, you set the calculation constant in the following way:
- If a kanban container is reported empty when all the material in the container has been used up, the calculation constant is set to 1.
- If several work centers are served by one production supply area when containers are reported empty in this way, the constant must be increased by the number of work centers.
- If, on the other hand, the kanban container is reported empty as soon as the first part is withdrawn, the constant is 0.
- You can also use this calculation constant to plan a safety stock.
- Smoothing Type
- If you want to smooth the dependent requirements for the kanban calculation, you must define the smoothing type. If necessary, you must also define a distribution function. The requirements can be evenly distributed over a week, a month, or a quarter.
- You can add a relative buffer to allow for requirement fluctuations.
- You can add a relative buffer to even out delivery fluctuations.
- Factory Calendar, Planning Calendar, Shift Grouping, Shift Sequence for the supply source
- If you have entered a replenishment lead time of less than a day in the control cycle, the system has to convert the daily dependent requirement quantity to the dependent-requirement quantity in this sub-day replenishment lead time. Before the system can do this conversion, it must be able to calculate the working time per day. The working time per day is calculated using the three above parameters.
- Note: In the kanban calculation, the system calculates the average working time (averaged over the period of examination).
- Factory Calendar, Shift Grouping, Shift Sequence for the demand source (consumer)
- You can model the working times of the consuming work center using these three parameters. From this information, the system then calculates the calendar buffer. The calendar buffer is a buffer that the system uses to compensate for the missing material quantity if the supply source does not work on a day on which the consumer (demand source) works, for example.
- The pull interval is used as a buffer covering lead times between the supply source and the demand source.
The parameters:
- Calculation Type
- Safety Factor
- Calculation Constant
can be overwritten in the control cycle.
The parameters:
- Smoothing Type
- Factory Calendar, Shift Grouping, Shift Sequence
can only be set in the calculation profile. Therefore, if you want to smooth the dependent requirements, or if you want to use a replenishment lead time of less than a day for the kanban calculation, you must maintain a calculation profile with these parameters, and assign it to the control cycle.
