Purpose – To determine the optimal software warranty period in continuous and discrete circumstances where the difference between the software testing environment and the operational environment can be characterised by an environment factor. Design/methodology/approach – Software reliability...

Purpose – To investigate the optimal burn‐in time from the perspective of minimizing the expected total cost (i.e. manufacturing plus warranty costs) per unit of product sold under a failure‐free renewing warranty policy. The conditions indicating when burn‐in becomes beneficial were...

Purpose – To provide a brief survey of the literature directed towards the analysis of warranty claim data. Design/methodology/approach – For convenience, this survey of the analysis of warranty claims data is somewhat arbitrarily be classified by topics as follows: age‐based claims...

Purpose – To provide a brief introduction to warranty analysis and a classification of general repairs. To introduce the notion of accelerated probability distribution and use it to model imperfect warranty repairs. Design/methodology/approach – The notion of accelerated probability...

Purpose – To consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service. Design/methodology/approach – The repair allocation problem is formulated as a convex minimum‐cost network flow problem and solve it by the successive shortest path...

Purpose – To make a theoretical comparison between two scale‐inspection and warranty policies for weight‐quality, one practical and the other theoretically grounded. Design/methodology/approach – Comparison is made in a Stackelberg game framework considering the consumer's as well as the...
