What is the primary goal of using multimodal transportation in logistics as per the discussed research?
|
To minimize transportation costs and risks while delivering on time. |
|
The primary goal of multimodal transportation is to optimize the entire logistics chain by using multiple transport modes (e.g., rail, sea, road) efficiently.

According to the case study, what is the primary commodity considered for transportation?
|
Electronics. |
|
According to the case study in the paper, the primary commodity considered for transportation in the multimodal route selection is electronics. This commodity typically requires careful consideration of cost, delivery time, safety, and reliability, making it ideal for analyzing multimodal transport options using decision-support models like AHP and ZOGP.

What is the role of the Analytic Hierarchy Process (AHP) in the multimodal transportation decision support model?
|
To establish weights for different criteria based on expert judgment. |
|
Prioritize multiple decision criteria such as cost, time, risk, and environmental impact. Use expert judgment to assign relative importance (weights) to each criterion through pairwise comparisons.

What does ZOGP stand for, and what is its role in the model?
|
Zero-One Goal Programming - It's used to solve the optimal route selection problem. |
|
ZOGP uses the weights provided by AHP to find the best combination of routes that meets the set goals as closely as possible.

In the context of the AHP used in the study, what does a consistency ratio (CR) less than 0.1 indicate?
|
The judgments are sufficiently consistent. |
|
A CR less than 0.1 (or 10%) indicates that the judgments made by the decision-makers are sufficiently consistent and reliable for the model.
If the CR is higher than 0.1, it suggests inconsistency, and the comparisons should be reviewed or recalculated.

What is the main natural cause of landslides along the Jammu-Srinagar National Highway?
|
Prolonged precipitation |
|
Heavy and sustained rainfall weakens slopes and triggers landslides in mountainous regions like along the Jammu-Srinagar National Highway. Other causes like earthquakes can also contribute but prolonged precipitation is the primary natural trigger.
