Method & Evidence

AimHow can the design and operational planning of process supply chain networks be optimized to balance responsiveness to demand changes with profitability?

MethodMathematical Optimization (Mixed-Integer Non-Linear Programming)

ProcedureDeveloped a multi-period mixed-integer non-linear programming model to simultaneously consider supplier and manufacturing site selection, technology choices, production levels, and scheduling. The model incorporates a quantitative measure of responsiveness (lead time with zero inventories) and is formulated as a bi-criterion optimization problem to maximize net present value and minimize lead time, generating a Pareto-optimal curve.

DV["Net Present Value (NPV)","Lead Time"]

CV["Demand changes","Multi-echelon, multi-site structure"]

Strengths & Limitations

Strengths

+Provides a quantitative method for assessing supply chain responsiveness.
+Offers a robust mathematical model for optimizing complex supply chain networks.

Limitations

Real-world supply chains have many more variables than can be modeled, such as transportation delays, quality control issues, and geopolitical risks.

Reliability & validity

The validity of the model relies on the accuracy of the input data and the assumptions made in the MINLP formulation. Reliability would be assessed by the consistency of results when re-running the model with the same parameters.

Think critically

How might the 'zero inventory' assumption for responsiveness impact the practical applicability of the Pareto-optimal curve in a real-world supply chain?

Design Principles

"For complex systems like supply chains, multi-objective optimization is crucial for understanding and managing inherent design trade-offs."

Designers and engineers must consider the inherent tension between agility and cost-effectiveness when developing supply chain networks. Understanding this trade-off allows for strategic decisions that align with business objectives and market demands.

What This Means for Your Design

To make a supply chain both fast and profitable, you need to make smart choices about where to get materials, where to build factories, and how to produce things, because making it faster might cost more, and making it cheaper might make it slower.
