In a single-stage decision tree problem, all decisions are made first and then all uncertainty is resolved.
Every path from a root to a leaf in a decision tree corresponds to a state in a state-based representation. However, it is frequently easier and more effective to express and think in terms of certain properties, which are referred to as variables.
All decisions in a single-stage design model must be made at the start of the planning horizon. Particularly, a single-stage formulation results in the identification of a system design that can address the entire spectrum of production issues, both present and future.
This refers to making a single choice in response to the input scenario tree, where the choice is represented by a striped circle at the decision node. The FFMS design approach's two-stage stochastic formulation enables the modeling of the manufacturing system's reconfiguration at a later time stage.
