Initial State

Initial state is a virtual copy of the current scenario, created at a user-defined moment of time with the additional data describing the state of the supply chain in that particular moment of time. This supply chain copy can be used as an entry point for simulation, i.e.by creating a new initial state you create a digital twin of the existing scenario that is simulated not from the abstract null, but from a certain point in time with a set of conditions and corresponding data.

Please note that:

  • You can create initial states for scenarios of SIM type only.
  • When started, the experiment considers only the current initial state. The succeeding initial states are not involved.
  • The Comparison and Custom experiments cannot use the initial states.

Supply chain state

First of all, every supply chain scenario has the start date and the end date. These dates define the simulation period (which may be further changed in the Periods table). The initial state can be created for any moment of time within the scenario's simulation period.

e.g. If the scenario's simulation period constitutes one year (01.01.2019 - 12.31.2019), then you can create as many initial states as required within this simulation period.

Second of all, every supply chain comprises a combination of objects, policies and other elements that are in permanent interaction with each other and have certain state at every particular moment of time. This means that if we create a digital twin on February 22, the supply chain will have been working by that time for almost 2 months:

  • Initial stocks may be gone
  • Certain demand may be satisfied
  • Factories may have produced certain amount of products
  • Some orders may have been delivered, while others may still be on their way, etc.

The Initial state that you create considers these processes and allows you to define the specific supply chain state in this particular moment of time, from which you want to start the simulation.
