;my-FCs: Vector which contains a number (0-1) that depicts an service's performance with a specific feature.
;           *FCs are enumerated.
;W*: list of values from other services
;S*: list of coalitions from other services
;joined: the coalition the service is associated with
services-own [ my-FCs W S joined my-price]

;requirements: Vector of requirements for a need that identifies the need of each feature.
;              *Size determined by num-FCs and enumerated in the same manner as my-FCs.
;coalition-in-use: As coalitions are associated with a need, they are added to this list for record-keeping
