In ‘A conceptual framework of vulnerability in firms’ inbound and outbound logistics flows.’, Göran Svensson separates inbound and outbound flows, adds 2 categories of disturbance (quantitative and qualitative), and also adds 2 sources of disturbance (atomistic and holistic) create 4 vulnerability scenarios.

Separating the chaff from the wheat and diving straight into the essence of the paper, Svensson aligns his framework along two dimensions, categories of disturbance and sources of disturbance. He then divides the categories into either quantitative or qualitative disturbances. Sources of disturbance are either atomistic (direct) or holistic (indirect).
