A dual transportation problem analysis for facility expansion/contraction decisions: A tutorial

A dual transportation analysis is considered as a strategic matter for plant facility expansion/contraction decision making in manufacturing operations. The primal-dual problem is presented in a generalized mathematical form. A practical technique of generating the dual solution is illustrated with a plant facility expansion/contraction example as a tutorial. Demand forecasting is performed based on the time series data with seasonal variation adjustments. The dual solution helps facilitate operations decision making by providing useful information.
