Is weather forecasting an example of a semi-structured situation? (1 Viewer)

[MrBrightside]

Is it?

 

[Dr No]

sup idiot

I would say yes - the requirements are clear and the procedure for arriving at a solution is known. (definitely not unstructured)
But we don't know the procedure for obtaining the best solution (it's often wrong...)

Not entirely sure how weather forecasting is done but I don't think all decisions there can be automated (which it would be if it were structured).

I said it was unstructured in my trials (even justified it) but got 0 for that Qs, and the sample answer said it was unstructured. Wtf. It should be semi-strucutred. It's backed up from raw data from the Bureau of Meteorology, that has a high probability of being correct.

Unstructured is more like winning the lottery or the stock market changing from day to day, where situations rely on chance alone and cannot be proven from hindsight. They require substantial judgement to come to a correct solution.

You should have received at least 1 mark for identifying the correct one. What did your teacher say about this?

I'm not sure if it's too late to get your mark changed as there is a BOS cut off date for sending student marks in.

Nah, it doesn't matter, I came first any ways. I Just want to make sure I'm 100% prepared for the HSC exam. My teacher said he was following the sample answers 100% and not accepting any other answers. Which is consistent, but unfair to people who actually studied and said semi-structured.

EDIT: Just re-reading over exam now, and it says that it was a flood emergency decision support system. But it still says that the DSS receives real-time data from the Bureau of Meteorology. :/

The sample answer says that the DSS is unstructured because there is a lot of uncertainty and often there is no method to reach a decision due to the nature of natural disasters. Also in unstructured situations judgement and insight is required. (which is also required for semi-structured but not as much).

I have a different teacher now, and he said that a "response to a nature disaster" was not unstructured, it was semi-structured. Ehhhhh everyone says something different ffs.

From memory though I think I remember that natural disasters require unstructured DSSs, how ever this question is weird as it says data is provided.

My answer:

Can you post up the original question?

From the syllabus, disaster relief management is definitely under unstructured.

Even though there is data coming from BOM, there is no specific procedure for arriving at a conclusion because natural disasters occur under very different circumstances. This is different from a weather forecasting system where you know you want to predict the weather for e.g. the next week - there are methods to predict it. In a natural disaster, your requirements aren't so specific.

Yes I can confirm that the syllabus states it as unstructured. Due to copyright reasons the exam is protected by copyright law and cannot be scanned or photocopied. But because they used an external source for the question I'll scan that.
