Design an identification and estimation strategy to measure the causal impact of reallocating inventory across regions on overall conversion yield when interference and capacity constraints exist. Discuss randomized designs (cluster or stratified), instrumental variables, synthetic control approaches, and how to adjust estimators for limited supply and spillovers between units.

Explain the difference between slack and surplus variables in linear programming with a brief algebraic example. In yield optimization, when would you use each and why (i.e., modeling ≤ vs ≥ constraints)?

List and explain the core data preprocessing steps you would perform before building an optimization model for supply-chain yield optimization. Cover handling of missing demand history, outlier sales spikes, lead-time variability, encoding categorical features such as supplier IDs, and capturing seasonality or promotions in time-series data.

Describe dual variables (shadow prices) in linear programming. In a constrained yield optimization example, how would you interpret the shadow price of a machine-hour constraint? Explain how you might use shadow prices to prioritize capital investments or outsourcing decisions.

When would you favor heuristic or metaheuristic approaches (e.g., greedy, simulated annealing, genetic algorithms) over exact LP/MIP solvers for yield optimization problems? Provide concrete problem characteristics (nonlinearity, very large combinatorial space, solution-quality requirements) and practical trade-offs between solution quality and time-to-solution.
