Designing acceptance sampling schemes for life testing with mixed censoring

Mixed censoring is useful extension of Type I and Type II censoring and combines some advantages of both types of censoring. This paper proposes a general Bayesian framework for designing a variable acceptance sampling scheme with mixed censoring. A general loss function which includes the sampling cost, the time‐consuming cost, the salvage value, and the decision loss is employed to determine the Bayes risk and the corresponding optimal sampling plan. An explicit expression of the Bayes risk is derived. The new model can easily be adapted to create life testing models for different distributions. Specifically, two commonly used distributions including the exponential distribution and the Weibull distribution are considered with a special decision loss function. We demonstrate that the proposed model is superior to models with Type I or Type II censoring. Numerical examples are reported to illustrate the effectiveness of the method proposed. © 2004 Wiley Periodicals, Inc. Naval Research Logistics, 2004

Keeping David From Bathsheba: The Four-Star General’s Staff as Nathan

Readers of reports on ethical failures by four-star general officers must wonder, “Don’t they have staffs to ensure that the general follows ethics rules?” The Department of Defense publishes robust ethics guidance in several documents; however, a staff’s best efforts to implement this guidance may fail to make an impression on a senior leader who is susceptible to the “Bathsheba syndrome,” an allusion to the biblical account where the prophet Nathan rebuked King David for his moral failings. This paper proposes a methodology to enable senior headquarters staffs to play the role of Nathan in supporting ethical behaviors by high-level officers. It examines the mechanisms that embed ethical behavior within members of those staffs in carrying out their three principal roles of advising, scheduling, and transporting the four-star officer. The authors offer a framework based on an ethical infrastructure of organizational climate that focuses the staff’s daily efforts to mitigate risk across seven ethical “danger areas” that threaten ethical failures by senior officers.

The Persistent Deficit of Militia Officers in the Swiss Armed Forces: An Opportunity Cost Explanation

The Swiss Armed Forces are suffering from a structural deficit of militia officers despite good pay and a general supportive attitude in the population. Whereas, prior studies have focused on motivation to explain understaffing in armed forces, we offer an alternative approach based on opportunity cost. We model decision alternatives both within and outside a military organization, taking private sector employment as the reference point. We then monetize opportunity costs of leisure, fringe benefits, and private sector income not compensated. Our results suggest that in terms of opportunity cost, service as a militia officer is the least attractive option, an effect that we believe explains the persistent staff deficit. Implications of these findings for the literature and recruitment policy are discussed.
