Is the following sentence grammatically correct ?

Hi,

s the following sentence grammatically correct ?

Coping with technical issues in real time AND (or UNDER) dynamic environment
Coping with technical issues in a real time, dynamic environment

It's not a sentence. It's a phrase.

Thank you Clive.

It's indeed a phrase, but I don't want to change the meaning. A friend suggested to use:

coping with technical issues in real time under a dynamic environment

It sounds fine to me

Hey Clive,

CliveHi,'Under' is not a suitable preposition. Say 'in'.Clive

It sounds weird to me using IN twice :

..in real time IN a dynamic environment

Don't you think ?

Thank you again.

Hi,
It sounds weird to me using IN twice :

..in real time IN a dynamic environment

Don't you think ? I wouldn't say 'weird'. Just not very stylish..
That's why I suggested
in a real time, dynamic environment,

Thank you again for your comment.

Since it's not very stylish to use IN twice, I wanted to use "UNDER" ,what might be not very common, but it doesn't change the meaning, until you said it's unsuitable. Anyway, I just can't use "," (comma), it changes the meaning of the phrase.

Thanks!

Hey again,

Because you can't say "in real-time.(period)" or "in real-time environment" without changing its meaning... You can use "," (comma) only if you use "real-time" as another kind of environment, what I don't want to do. The "real-time" describes the time, while "dynamic" describes the environment.

Thanks again.

I'm sorry. I shouldn't have written "AND" at all, only "under", that's what probably made it so unclear
