Two types of multidimensional processes are defined. The first of these generalizes a univariate IFRA process due to Ross and relates to a multivariate concept of IFRA due to Esary and Marshall. The second of these relates to a multivariate concept of IFRA due to the present authors. Decompositions for multistate monotone structure functions are given and behavior of nonincreasing stochastic processes such as those given above is analyzed. Various coherence assumptions for multistate systems are also analyzed.
