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 if we only have one way to transport in logistics when it's not suffice or prevented. We won't be able to transport in logistics.
|
To create transportation, we need these key objectives, such as cost reducing, simple, and safe.

Which method is primarily used for decision-making in multimodal transportation route selection?
|
A combination of AHP and ZOGP. |
|
Because when we need to make a decision in multimodal transportation route, we need to analyze it. So, we need to use AHP and ZOGP to analyze all the possible pros and cons of the choices.
|
Because AHP is like an advanced analyzing with various choices that ordinary human can understand and make a decision. And ZOGP has binary number which AI or computer system can help analyze and make a decision.

According to the case study, what is the primary commodity considered for transportation?
|
Coal. |
|
Because coal is not that expensive, so we need to transport in high volume to make it cost efficient.
|
Coal is commonly transported. Because it is cost sensitive, complex, and large-scale in logistics. Because it is used in almost many kinds of production, such as food, cleansing, and energy producing.

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. |
|
AHP helps people to decide that which choice is the choice they want.
|
AHP helps people to break down the problems and relate the importance of their choice. It also support ZOGP and bring us structured and transparent methods.

Which risk is NOT considered in the list of risks assessed for multimodal transportation route selection?
|
Health risk. |
|
Because health is related with human, and human isn't considered in a list of risks.
|
Because multimodal transportation is mainly about logistics, not health which is relevant to HR and organizational resources.

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 stands for Zero-One Goal programming, which is a type of analyzing used to help decide the best route for the problem solving.
|
ZOGP's role is to help human like us to compared the routes or the choices in a certain problem that which one is better or more compatible with certain moment.

Which of the following is NOT a mode of transport discussed in the multimodal transportation case study?
|
All are discussed. |
|
Because all of the choices above are included in multimodal transportation. All of them are transportation routes which used worldwide.
|
Because the only mode which is not discussed in multimodal transportation is pipeline. And pipeline is mainly used for gases and liquids, which is not compatible with other freight modes for intermodal containerized transport.

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. |
|
Because in AHP context, CR or consistency ratio is used to indicate that the judgements are consistent or not.
|
If CR is less than 1, the judgements are consistent.
If CR is more than 1, the judgements aren't consistent.

What is the primary purpose of sensitivity analysis in the context of the ZOGP model used in the study?
|
To reduce the cost of the project. |
|
ZOGP is mainly used for decision-making process to solve the problems.
|
It helps to identify which variable have the most influence on the outcomes.

Which of the following best describes the role of multimodal transportation in global trade according to the study?
|
It is essential for making local industry and international trade more efficient and competitive. |
|
Multimodal transportation is used to make transportation faster, cost efficient and reliable.
|
Multimodal transportation enhances efficiency by optimizing delivery times, costs, and reliability for the industries and trading.

What is the main natural cause of landslides along the Jammu-Srinagar National Highway?
|
Prolonged precipitation |
|
Because landslides are mostly caused by heavy rainfall.
|
Heavy rainfall reduces dirt friction and increases the weight of slope dirt, which can trigger landslides.

|
Remote sensing and ARIMA modeling |
|
They can tell us both where and when landslides are likely to happen.
|
Remote sensing is used to identify existing landslides and map terrain.
ARIMA is used to predict rainfall patterns or landslide over time based on historic data.

What is the relationship between land surface temperature (LST) and underground water level mentioned in the study?
|
LST decreases as underground water level increases |
|
This inversion is important for identifying high moisture areas and monitoring environmental changes
|
When LST increased, it shows lower soil moisture and reduced groundwater levels.
When underground water increased, it shows higher soil moisture and increased groundwater levels.

If the mean monthly rainfall in April is 150 mm and it increases by 20% in May, what is the mean monthly rainfall in May?
|
180 mm |
|
The mean monthly rainfall in April increased by 20% in May.
|
Because 150*(20/100) = 30 and 150 + 30 = 180 mm.

|
0.24 |
|
Because the slope angle is 45 degrees and the friction angle is 11.
|
Because 11/45 is around 0.244 or 0.24.
