Truncated Sequential Life Tests for a 3-Way Decision Procedure

Eleven sets of test plans are given for testing ``¿ = ¿0´´ against the alternative ``¿ = ¿1 < ¿0´´ and ``¿ = ¿2 > ¿0´´ where ¿ is the failure rate. The results are useful for incentive plans and life-cycle costing applications, and are fundamental in the life testing of equipment, whether a consumer or industrial item, during the constant failure-rate period. The theory and equations for the calculations of the tables and plans are developed and discussed and the related references are included.
