Description

The initial-production phase of new products or new manufacturing facilities is often unstable because of inexperienced workers and defective products. An initial-production process control, in which the defects in design, production technologies and products are fully fixed and removed, is switched to normal process control whenever it is ready for actual mass-production. This paper discusses a method of deciding the optimal initial-production control-period based on a reliability growth model. It is determined by the number of products with the minimum total expected quality control cost. Finally, a penalty cost due to unattainable loss to the quality goal is introduced in the quality control cost: the realized stabilization of initial-production process control is lower than the original goal. Numerical illustrations for the optimal policies are also presented.
