Ratio

Statistics related to this group provide detailed information on the utilization of various supply chain elements during the Simulation-based experiments, as well as quality of provided delivery services (based on the analysis of the received ( Fulfillment Received (Orders On-time), Fulfillment Received (Products On-time), Fulfillment (Late Orders), Fulfillment (Late Products)), sent ( Demand Placed (Orders) by Site ) or initially dropped ( Demand Placed (Dropped Products) by Customer, Demand Placed (Dropped Orders) by Customer) orders/ordered products).

Bullwhip Effect by Product

Shows statistics on product demand variability amplification during the supply chain simulation: from the point of actual (final) product items demand to the point of origin (DC, factory).

  • BWE > 1 means that outgoing variability prevails over the incoming
  • 0 =< BWE < 1 means that incoming variability prevails over the outgoing
  • BWE = 1 means there is NO bullwhip effect
  • BWE = -1 means that incoming variability is 0

The bullwhip effect is defined as:

Where:

  • - variance in demand
  • - expected value
  • - outbound orders
  • - inbound orders

The data is:

  • Updated each model day.
  • Collected per:
    • Type - the type of object the data is collected on (DC, Factory).
    • Object - the name of the object (DC, Factory) the data is collected on.
    • Product - the products the data is collected on.

ELT Service Level by Orders

Shows the service level based on the ratio of on time orders to the overall number of outgoing orders.

The ELT Service Level by Products and the ELT Service Level by Revenue statistics are calculated in the same way, the difference lies in the data extracted from the calculation:

  • ELT service Level by Products - shows ratio of products delivered on time to the overall number of products shipped. The data on products is taken from the processed orders.
  • ELT service Level by Revenue - shows the ratio of on time orders to the overall number of outgoing orders in terms of money received.

The ELT Service Level by Orders statistics shows service level calculated based on the expected lead time.

The value is defined as:

Where:

  • number of on time orders - the number of orders that were delivered within the expected lead time.

The value does not include placed orders that are not yet shipped, delayed or dropped (such orders can still be delivered within the Expected lead time specified in the Demand table). Note that for ELT-based service level, dropped orders are excluded from outgoing orders if backorder policy for the selected customer is set to Not Allowed (backorder policy is defined in the Demand table).

The data is:

  • Updated at the end of the day.
  • Updated each time an order is received / delayed / dropped.
