How to use the scenarios and alternatives?

Based on the situation AS-IS and analysis of previous flows, it is possible to create all possible scenarios.

A alternative is used to test the location of teh machines.

A scenario is used to test a new design (new working area, new aisles…), solutions with new investments in term of machines or new routings for the parts.

Modify the location of the machines in the As-Is sitiation

  • Duplicate « Alternative AS-IS »
  • Changing the positions of the machines has a direct impact on the mileage (in green if a gain is observed if not red)

New scenario based on the rerouting of flows

To create solutions based on the rerouting of flows performed in the graphical view of the “Scenario 2”:

  • Work in Scenario 2 alternative “S2RA1”
  • Determine incremental changes (in terms of positioning of machines):
    • Modify « S2RA1 »
    • Duplicate« S2RA1 » en « S2RA2 »
    • Modify « S2RA2 »
    • Duplicate « S2RA2 » en « S2RA3 »
    • Modify « S2RA3 »

..hint each stage to be saved must be duplicated in order to keep the changes.

  • Modify the design of the factory
    • Duplicate Scenario 2 (Scenario 3 =)
    • Modify the design (delete cells, create new cells …)
    • Delete the non-useful alternatives from the previous Scenario 2 (“S2RA1” and “S2RA2”)
    • Start to change the alternative “S3RA3” (new design with machines positioned as the last alternative scenario 2)
    • Proceed with incremental changes to create a different alternative “S3RA3”, “S3RA4” to “S3RA5”

Incremental changes (via alternatives) can result in freeing up of an area so as to facilitate redesign. (via a new scenario).

Using the Dashboard

process_real_11_dashboard

The dashboard allows you to compare different real alternatives to quickly and easily visualize which is the best of them. It contains several data:

  • The name of the alternative and it’s scenario .
  • Total cost that represents the situation
  • The percentage gain this situation than that indicated as the reference
  • The total number of kilometers traveled by products
  • The total time

To determine what is the alternative reference, you either go through the Scenario menu, or right-click on the selected alternative and choose “set as baseline” option. Computing the winning percentage of alternatives will be based on this alternative reference.

Fermeture

menu_file_close

When closing the opened case with the command “Close” in the menue “File”, it will first ask it a backup of any changes made to the current case is necessary.

message_close

If the response is “Yes”, the modification will be saved in the original file xml. On the contrary, the modification will be lost.
