Insight’s SCOREKEEPER offers a dynamic, stochastic simulation model of a supply chain. This is an event‐driven model with a built‐in clock that emulates supply chain activities. The term stochastic means that certain components of the model are represented as random variables. Examples include customer demand, transit and product batch sizes. It is an optional component of the INSIGHT SAILS (Strategic Analysis of Integrated Logistics Systems) product which addresses complex strategic questions.
