In this paper we study the distributional properties (mean, variance, characteristic function) of the discounted warranty cost (DWC) for general warranty programs including free replacement (FRW) pro rata (PRW) and FRW/PRW in the context of perfect repair. Since only failure times and types are needed in the derivation of these properties, the reliability of the systems is modeled according to ...

BACKGROUND Evidence-based policies encouraging healthy behaviours are often strongly opposed by well-funded industry groups. As public support is crucial for policy change, public health advocates need to be equipped with strategies to offset the impact of anti-policy messages. In this study, we aimed to investigate the effectiveness of theory-based public health advocacy messages in generating...

This paper examines and compares various manufacturing policies which manufacturer may adopt so as to improve the performance of a vendor managed inventory (VMI) partnership. The goal is to maximize the combined cumulative profit of supply chain while minimizing relevant inventory management costs. The supply chain is a two-level system with a single manufacturer and single retailer at each lev...

The red-blue state and urban–rural narratives— which depict that people living in red states and rural areas oppose pro-LGB policies—are popular frames for describing variation in public opinion of LGB policies by geographic region. In a test case of a red state, we examine public opinion of pro-LGB policies to assess the accuracy of the red–blue and urban–rural narratives. Using data from a su...

4 Sales delay is the time interval from the date of manufacture to the date of sale. In analysing 5 warranty claims data, the existing research relating to the sales delay has mainly focused 6 on estimating the probability distribution of the sales delay. Longer sales delay may lead 7 to more warranty claims as it can have an impact on the post-sale reliability of products. 8 However, research ...
