vertical market system (VMS)

Formally or informally coordinated distribution channel where its independent members work together to achieve greater efficiency and economies of scale, and to eliminate channel-conflict arising out of disparate individual objectives.

(2) Contractual: independent production and distribution firms formally agree to integrate their resources.
