ipolo 4 Material Flow: Order and transport calculation (possible errors)

1. A means of transport type lacks an assigned shift plan

Solution: Assign a shift plan to all deployed means of transport.

To do this, switch to the “Shift plan management” submodule and select the desired shift plan for the desired means of transport, or select a global shift plan in the window on the right:

2. No worker type assigned

Solution: Assign a worker for all transport processes.

To do this, switch to the “Create routes” submodule and select a worker type for the desired route:

3. Order time exceeds maximum tour duration (clocked tours)

Solution: Adjust the maximum tour duration, the route itself or the processes in the supply chains.

To do this, switch to the “Create routes” submodule and adjust the maximum duration of the tour in question or delete the maximum tour duration by setting it to 0 min:

Alternatively, switch to the “Standard process chain” submodule and identify where the total number of processes in a route transport exceeds the maximum tour duration:

It may also be that the travel time of a tour is too long for the maximum tour duration. Adjust the route of a tour accordingly in the “Create routes” submodule. Find out more here: Create routes.

 

4. No suitable cycle (clocked tours)

Solution: Adjust either the cycle or the affected orders - the orders cannot be completed within the cycle without waiting times, although they can be completed according to the shift plan.

 

5. Average speed of the means of transport is 0

Solution: Enter an average speed >0 for all means of transport.

To do this, switch to the “Resource management” submodule, select the corresponding “Direct means of transport” or “Tugger” tab and adjust the average speed of the means of transport:

 

6. No means of transport type assigned

Solution: Assign a means of transport for all transport processes.

To do this, switch to the “Create routes” submodule and select a tugger train type for the desired route:

 

7. Stopping point of the source differs from the stopping point of the route start

Solution: Adjust the stopping point of the route start to the stopping point of the source, or vice versa.

To do this, first switch to the “Process chain editor” submodule [1] and search for the affected standard supply chain [2] or the corresponding supply chains [3]. Here you can determine the exact stopping point [4] of the source, which must be adjusted on the entered route [5]:

Now switch to the “Create routes” submodule and search for the route entered in [5]. Adjust the starting point of the route to the starting point in the source [4] using the “flag” symbol in the function bar:

 

8. Stopping point of the source is missing

Solution: Add the source in the supply chains.

To do this, first switch to the “Process chain editor” submodule. Select the relevant standard supply chain and then the supply chains (multiple selection possible). Then go through the individual stages and make sure that a stopping point is specified in the source for each stage:

 

9. Stopping point of the sink is missing

Solution: Add the source in the supply chains.

To do this, first switch to the “Process chain editor” submodule. Select the relevant standard supply chain and then the supply chains (multiple selection possible). Then go through the individual stages and make sure that a stopping point is specified in the sink for each stage.

 

10. No valid stopping points set

Solution: Adjust the stopping points of the route network.

To do this, switch to the “Create route network” submodule and take a look at the distribution of the stopping points on your route network. The stopping points should always be located close to the corresponding material area and must have been assigned in this way beforehand (more information here: Create route network). Routes created by you must in turn run via stopping points to enable the material flow.

If this is not the case, create new stopping points using the “H+” symbol in the function bar and assign them to a material area using the button below:

Then switch to the “Create routes” submodule and plan the route so that the breakpoints enable the material flow.

 

11. No suitable shift

Solution: Change the current shift or create a new one.

To do this, switch to the “Shift plan management” submodule. Here you can create a new shift plan, adjust the shift plan time to extend the shifts or create a new shift that fits better into the time requirements of the orders:

 

12. A single order alone exceeds the capacity of an entire tour

Solution: Locate the affected order and adjust it or adjust the tour.

 

13. No trailer type defined

Solution: Add the trailer type in the supply chains.

To do this, switch to the “Process chain editor” submodule. Select the relevant default supply chain and then the supply chains (multi selection possible). Then go through the individual stages and make sure that a trailer is selected for each route transport (which also has enough capacity):

 

14. No route to the sink found

Solution: Adapt the route or select a different stop for the sink.

To do this, switch to the “Process chain editor” submodule and identify which stopping point at which sink is affected:

In this case, it would be stopping point 42. See if you can replace the stopping point with another one that is on the associated route.

Then switch to the “Create route network” submodule and take a look at the distribution of stopping points on your route network. If necessary, adjust the route in the “Create route” sub-module so that it runs via the stopping point of the sink.

 

15. No destination sink found

Solution: Add a stopping point for use as a sink.

To do this, switch to the “Create route network” submodule and add a stopping point where your sink is located. Also assign the corresponding material area to it.
