Abstract
Reliability engineers must not only consider the consumption of energy, capital and material resources, but also seek more economic means of completing experiments effectively. This study derives formulae for computing ratios of expected type‐II censoring times and expected complete sampling times when the lifetime adheres to two‐parameter Pareto and Rayleigh distributions. Utilizing such formulae allows the construction of tables providing information about how much experiment time can be saved by employing a type‐II censoring plan instead of a complete sampling plan. Engineers can employ the proposed tables to determine the censoring number, the initial sample size and the other relevant parameters for reducing the total experiment time. Illustrative examples demonstrate the effectiveness of the proposed procedure.

Abstract
Purpose
This paper aims to explore the effectiveness of children as advertisement endorsers in the airline context, including images of safety and reliability.
Design/methodology/approach
This paper is intended to examine the advertising effect of endorsers (celebrities, CEOs, experts, consumers and children) in the context of the airline industry. A factorial experiment was conducted to test the communication effect (CE) of ten groups of advertisement combinations (five endorser types – with/without safety attribute).
Findings
The results indicate that a child endorser yielded a better CE than celebrity, CEO or typical consumer endorsers. Second, advertisements that emphasized safety had better CE than those without this emphasis. The group combining children and safety generated a better CE than most of the other groups comprising different combinations.
Practical implications
A child endorser and a safety message are recommended to be used in advertisements for airlines because flight passengers place importance on safety. Fragile image of child reinforces safety of an airline.
Originality/value
The integration of advertising endorsement and message into a conceptual model allows the current results to provide meaningful theoretical and practical implications.
