Essay | Explanation: ZOGP is used to generate the optimal route by integrating weights obtained from AHP.
|
Zero-One Goal Programming (ZOGP) plays a crucial role in optimizing multimodal transportation routes by integrating weights derived from the Analytic Hierarchy Process (AHP). This essay will explain how these two techniques work together to generate the optimal route selection.
|
|
The combined application of AHP and ZOGP offers a powerful approach for optimizing multimodal transportation routes. By leveraging the prioritization framework of AHP and the optimization capabilities of ZOGP, this approach facilitates data-driven decision-making that considers various criteria while respecting the decision-maker's priorities. This integration ensures the selection of a route that is not only feasible but also aligns with the established goals and preferences.
|
ZOGP is an optimization technique specifically designed for problems where decision variables can only take binary values (0 or 1). In the context of route selection, this translates to choosing a single route from the available options. ZOGP utilizes the AHP weights in the following manner:
