Dynamic programming approach to solve multi-period production planning problems with time-dependent costs and constraints. The method uses backward induction to solve the multi-period optimization problem, computing optimal decisions recursively from the final period. State variables track period-specific information (inventory, demand), and value functions represent minimum cost to reach the terminal period. Table of Contents: - Aggregate planning problem definition and planning horizon - Demand aggregation across products and time periods - Decision variables: production rate, workforce, inventory, backorders - Constraint formulation: demand satisfaction, capacity, inventory balance - Cost components: production, inventory holding, workforce hiring/firing, backordering - Objective function: total cost minimization - Dynamic programming principle: optimal substructure property - Multi-period decision problem formulation - Stage-based decomposition and state variables - Value function: minimum cost to go from current state to end - Backward induction recursion and Bellman equation - Stage-dependent cost functions and transition equations
