  By a theorem of Christensen and Hovey, the category of non-negatively graded
chain complexes has a model structure, called the h-model structure or Hurewicz
model structure, where the weak equivalences are the chain homotopy
equivalences. The Dold--Kan correspondence induces a model structure on the
category of simplicial modules. In this paper, we give a description of the two
model categories and some of their properties, notably the fact that both are
monoidal.
