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. |
|
Because each modes have their strengths and limitations therefore combining them all can reduce their risks and cost overall.
|
From the total logistic cost theory, using multimodal transportation means concising cost because using only one mode may be fast for transportation but expensive. Therefore, the cheaper and slower modes will be used instead and for where is needed, the faster and more expensive modes will do.

Which method is primarily used for decision-making in multimodal transportation route selection?
|
None of the above methods are used. |
|
The method used is not mentioned above. The methods used to decide on multimodal transportation consists of each from different parts of decision making: mathematics, route planning, decision making with criterias

According to the case study, what is the primary commodity considered for transportation?
|
Coal. |
|
It’s one of the world most important natural resources therefore it’s being transported most.
|
Because coal is transported in many different ways, coal was used to conduct this case study.

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. |
|
This process is for determining how the main criteria like transportation cost, time and risks weighs out.
|
It is a technique developed by Thomas L to mainly help with decision making.

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. |
|
Although ZOGP has an inability to weight criteria’s, it is used for decision making and in this case: finding the optimal route.
|

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. |
|
It means that the judgement is okay to use further on and doesn’t need more recalculations
|
The last part of the analytic hierarchy process stated: if CR is NOT less than 0.1 the judgement needs to be carried out once more for a consistent decision. Therefore, if CR is less than 0.1 it is already consistent.

What is the main natural cause of landslides along the Jammu-Srinagar National Highway?
|
Prolonged precipitation |
|
The highway has been receiving maximum rainfall because it hasn’t been raining previously, causing the landslide.

|
Remote sensing and ARIMA modeling |
|
It is used to determine the threshold values that trigger a landslide and the probability of landslide occurrence.

|
Directly proportional |
|
This means that as the LST increases, the underground water level increases and same way vise versa.
