  ECOMB is established as a hadronic multiparticle production generator by soft
interaction. It incorporates the eikonal formalism, parton model, color
mutation, branching, resonance production and decay. A partonic cluster, being
color-neutral initially, splits into smaller color-neutral clusters
successively due to the color mutation of the quarks. The process stops at
hadronic resonance, $q\bar q$ pair, formation. The model contains self-similar
dynamics and exhibits scaling behavior in the factorial moments, e.g. the
intermittency.
