Cost Analysis of a designed system

hi burhan nun mina llah

it is surely a necessary aspect of any product design.
here i am posting the link to an IEEE paper on life-cycle cost analysis. i hope it helps you.

Hi Burhan num mina llah..

you are welcome. are you trying to do cost analysis of any product or design?
Surely, before even asking for funding, one needs to be aware of the cost budget of the system.
If budget exceeds the available financial assistance, one could face hick ups. All the best.

Best Wishes

Hello Burhan

I am little bit confused about your query. Do you mean link budget / power budget by the cost analysis here?
If so then i would like to mention that Link budget and power budget are two different things but are related to each other. A data link will only operate if the cable plant loss is within the power budget of the link.
The terms “power budget” and “loss budget” are often confused. The power budget refers to the amount of loss that a datalink (transmitter to receiver) can tolerate in order to operate properly. Sometimes the power budget has both a minimum and maximum value, which means it needs at least a minimum value of loss so that it does not overload the receiver and a maximum value of loss to ensure the receiver has sufficient signal to operate properly.
The link budget is the amount of loss that a cable plant should have. It is calculated by adding the average losses of all the components used in the cable plant to get the total estimated end-to-end loss. The link budget has two uses, 1) during the design stage to ensure the cabling being designed will work with the links intended to be used over it and 2) after installation, comparing the calculated loss to test results to ensure the cable plant is installed properly.
For your reference i am attaching the link which might help you in calculating link budget in FTTH networks.

Thanks

For your reference i am attaching the few more links which might help you.

instead of calculating cost due to each component u can represent ur design cost by an empirical formula which can be calculated
from ur proposed architecture. and this equation can be used by different vendors to calculate the cost.

Hello Everyone,
This is an very important aspect of any design and it would be worth discussing.
Umer Ashraf do you mean that we need to devise the empirical formula for our design on our own or it is some common expression given?
If so can you help in that regard i mean how we derive that formula for our system. I will be highly appreciable.
Regards

Dear abid it is pure mathematical modelling
If u know numerical methods then u can do it.

Hello Umer,
Thank you for the valuable inputs. Shall look into it.

hello..sorry for interrupt you guys… can anyone help me to solve my problem. actually i use numerical method (split step fourier method) in matlab to prove the effect of fiber losses, dispersion and non-linearity in optical soliton and also need to compare that result with optisystem. actually, i already got the result from optisystem for fiber losses, dispersion and SPM. i compared the effect of fiber losses (alpha), GVD (beta2), and SPM (gamma) based on the 3 physical length. (i picked 10km, 20km, and 30km).but here, i need to tally the result with matlab (split step fourier method) n must be the same result with optisystem. i try to change the coding, but it failed. since i picked 3 physical length in optisystem result, so i need to setup the same physical length in matlab coding to test the effect of fiber losses, GVD,and SPM.. i hope you guys help me to solve this problem.. i tired to thinking how to solve this problem. here i attached the coding and the result from optisystem.

Hello Everyone,
Thanks for sharing but please try making it more of a discussion rather than copying and pasting. Please refrain from this. It is not good. Thanking you.
