Optimal sequential designs are investigated for experiments to test whether a device subjected to a standard stress has an expected lifetime exceeding a specified value. It is assumed that the lifetime is exponentially distributed, with expectation a function of the stress and an unknown parameter; we assume this function is known (at least for some range of stresses). At each stage of experimentation, the experimenter chooses a stress level and obtains an observation of lif time at a cost proportional to the expected lifetime, i.e., proporional to the expected length of time requir d to obtain the obser ation. This cost may make it desirable to choose a greater than standard stress and perform an accelerated test. The case where the reciprocal of the expected life time is a quadratic function of stress is given particular attention. At each stage of experimentation, the optimal design involves randomizing between at most two stress levels. (Author)

This study is concerned with the problem of choosing the amounts x sub 1, x sub 2, ..., x sub n of a single product (or aggregation of several products) to produce in each of n successive time periods 1,2, ..., n so as to minimize the total manufacturing costs over the n periods. The requirements r sub 1, r sub 2, ..., r sub n for the product occurring in periods 1,2, ..., n are assumed to be known in advance. Requirements in a period are satisfied in so far as possible from stock on hand at the beginning of the period and from production during the period. Requirements which cannot be met in this was are back logged until they can be satisfied by subsequent production
