[DRAFT] improved multi-objective estimation

copy of [PoC with Multi-criteria / Matheus Bernardelli #104](https://github.com/equinor/dot-archive/issues/104)

> Create understanding of the approach from Matheus Bernardelli about mutli-criteria decision-making.
Paper is in SharePoint: Documents/cases/KVG OR Documents/02_literature/01_topics/mutli-criteria_decision_making_Bernadelli
What would be a good way of implementing something in the frontend? What needs to be changed in the backend?

Start by reviewing the linked PoC, issue #104, and the referenced Bernardelli paper in SharePoint. Use them to understand the proposed multi-criteria decision-making approach, then identify what frontend and backend changes would be required. Done means an agreed implementation direction and defined scope, rather than a small isolated code change.
