title: Customized weight based ranking mechanism
body: <p>I have the following problem I would like to tackle.
  I have a list of elements 'Ei' (element i), each with several parameters.
  The parameters are similar and each is assigned with a weight 'Wx' (Weight for parameter x).</p>
  
  <p>The weight can be changed according to preference.
  I need to rank/prioritize the elements according to the parameters and their weights.</p>
  
  <p>Are you familiar with any approach/technique/solution for a similar system?</p>
  
  <p>Thanks</p>
