The submodule Means of Transport Calculation Preview can be found in the module Transportation Planning.
Here routes are evaluated according to the VDI norm 5586. The calculation of the VDI standard was extended here for a higher accuracy by empties and grouping transports, as well as an evaluation of direct transports.
With 1 you can switch the view between "term based" and "formula based", so that you can also display the formula symbols here.
Above the graphs, the values used for the calculation are displayed.
Notes on the calculation:
Load units are treated like load carriers: If a load unit is larger than the standard load carrier, the NLT equivalent is 1, if a load unit is smaller than the standard load carrier, the NLT equivalent is calculated.
Disposal chains are considered analogous to supply chains.
For grouping chains, the value of grouping transports per day is determined as follows:
Products per day / Number of compartments for the grouping box / Number of grouping boxes per grouping load unit
For the calculation of the NLT equivalent, the dimensions of the grouping load unit are always used here (regardless on whether grouping box or grouping load unit was selected)
Via 2 you can switch between the routes and the direct transports.
All used combinations of means of transport are listed here, sorted in descending order according to the respective workload.
Notes on calculation:
The transportation means requirement between two stages is calculated as follows:
Transports per day per LOG ID = LC per day / division factor
Transports per day per LOG ID = LU per day / division factor
The division factor is always the minimum of the reorder quantity and the stacking factor for the respective transport (stored in the respectivesupply chain).
The transport duration is calculated from the distance and speed of the means of transport used.
The transports per day determined above are then multiplied by the transport duration: Result A
For the duration oft the processes, the loading and unloading times stored for the transport are added up.
The transports per day determined above are then multiplied by the process duration: Result B
Result A and result B are added and assigned to the respective transport means combination - this must be done for all stages where the respective transport means combination is used: Result C
Under 1 (see above) an empty trip percentage of 10% is stored by default. This value can be changed and confirmed with Enter so that the calculation is adjusted directly.
Result C is therefore multiplied by this precentage of empty trips and, if necessary, an allowance time (can be stored in the resource management) of the worker used.
This value is then divided by the net working time (in case of different shift schedules for workers and means of transport, the net working time of the means of transport applies) to obtain the number of means of transport per shift. The number per day as well as the rounded number per day is calculated by counting the individual shifts.
Average workload = calculated number / rounded number
Grouping chains are not taken into account here.
