This report evaluates production plans and remanufacturing strategies in dynamic systems, suggesting cost-reduction opportunities.

The aim is to develop a production plan addressing remanufacturing of used products while considering uncertainties in demand.
Formulated a constrained time-discrete linear quadratic gaussian (LQG) production planning problem.
Estimated return rates to assess production scenarios for remanufacturing.
Converted the LQG problem to a deterministic equivalent solvable by quadratic programming methods.
Illustrated concepts with a simple use case.
Developed sub-optimal inventory and production plans.
Enabled managers to evaluate scenarios for cost reduction through optimized remanufacturing strategies.
Demonstrated the importance of reusing materials due to environmental legislation and raw material shortages.

Salviano et al. (2017) studied this question.
