A matheuristic for the traveling salesman problem with positional consistency constraints

International Transactions in Operational Research, EarlyView.
Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.

A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

Monopoly Versus Dual‐Channel Distribution With Multiple Retailers

The Journal of Industrial Economics, EarlyView.
ABSTRACT This paper examines how downstream competition shapes a manufacturer's decision to adopt a dual‐channel structure—supplying independent retailers via secret two‐part tariff contracts while also operating a direct channel. We show that the shape of the inverse demand function plays a key role in this decision.
