Decision Matrix to help with design spiral

A decision matrix is a tool that allows to quantify different elements of a design. To start with, each element is given a percentage of the total value within the design. This is a decimal and all the values added have a value of 1 and are called "weight". The weights are a combination of subjective values and constraints. I include an example on a comparison between solar panels and three different wind chargers. In this case noise is 0.2 (20%) of the total. In an isolated location it might be 0.0 and in a location with noise regulation 0.7. Personal preferences are also an influence. The matrix allows for comparison of diverse solutions to a problem, with all of them judged by the same standards.

 

A good way of summarising a complex problem.
I was looking for an element called Performance eg Output, but I suppose the 2 Efficiency lines could encapsulate that somehow.

 

It looks to be a spreadsheet so you will be able to add lines and columns for any parameters you like I would say and there might be an open source solution that is independent of spreadsheet software also. Speaking of open source software have you seen this little gem? Bareboat Necessities OS Documentation https://bareboat-necessities.github.io/my-bareboat/bareboat-os.html

 

It is usually in Excel. You can add as many rows or columns as needed.

 

Seems like they are only interested in electronics. I would put a spare anchor much higher in the list.

 

I am not sure if it is within the responsibilities of a boat management computer to deploy a secondary anchor, though I guess there could be automatic systems designed for controlling an anchor winch.
