Abstract: Consider an n-job stochastic bottleneck assignment problem in which the production rates are independent random variables rather than constants. Assume that the production rate, R ij , (R ij \geqq 0; i, j - 1, 2, ..., n) of man i when assigned to job j is: (1) exponentially distributed with mean 1/\lambda ij or (2) Weibull distributed with scale parameter \lambda ij and shape parameter \beta. It is shown that in either case, the assignment that maximizes the expected rate of the entire line is found by solving the deterministic assignment problem with "cost" matrix [\lambda ij ].
