“…To understand the influence of overloading on the overall network reliability, its influence on the component reliability should be understood first. For this purpose, we employ the model proposed by Kim et al to describe the load‐failure relationship of each edge, with its baseline load equal to its designed capacity. If an edge's flow l e is less than or equal to its designed capacity q e ( e ∈ E ), the scale parameter θ e of its failure time distribution remains fixed as

The economic development and social well‐being of modern societies are highly dependent on networked critical infrastructures to satisfy the necessary demand. In the case that the prescribed demand cannot be satisfied with each component of a network normally loaded, certain components need to be overloaded. To study the influence of overloading on the network reliability, this research proposes a new flow‐redistribution rule based on minimal cuts to determine the components to overload when necessary and the way to redistribute the network flow. The proposed rule can help to keep the prescribed demand for a network satisfied, while trying to minimize the adverse influence of overloading on the network reliability. Based on the proposed rule, we then propose a bi‐objective optimization model to identify a network's critical components that, among all the possible combinations of components with the same amount, influence the network reliability the most when incapacitated, while considering the possibility of overloading and its influence on the reliability.

“…Apparently, a lower value of γ e implies less influence of overloading on component reliability. Note that although we utilize the model proposed by Kim et al, other models describing the load‐failure relationship of component such as PHM and AFTM can also be employed in the proposed approach.…”

“…Ja, Kulkarni, Mitra & Patankar (2001) consideran el problema de la estimación de los costos y de las reservas de garantía durante el ciclo de vida de un producto reparado mínimamente y bajo una política de garantía sin renovación, en la cual los costos de los reparos dependen de la edad del producto, e indican cómo usar la información de los costos de garantía para determinar el período de garantía; Kim, Djamaludin & Murthy (2001) estudian modelos para el análisis del costo esperado de garantía bajo una política FRW para productos con intensidad o tasa de falla dependiente del uso; Bai & Pham (2004) discuten el problema de la estimación y la predicción de los costos de garantía descontados, usando políticas FRW y PRW, para sistemas en serie reparados mínimamente, y aplican sus resultados en la determinación del período de garantía y de las reservas para el servicio usando el Teorema de Límite Central. Chien (2005) considera el problema de la determinación del períodoóptimo de garantía y de la edad de sustitución del producto después del vencimiento de la garantía, según las perspectivas del vendedor y del comprador, respectivamente, que minimizan las funciones de costos correspondientes, considerando el modelo denominado de falla general.…”

Estas aplicaciones corresponden a extensiones propuestas en este trabajo de problemas formulados previamente en la literatura de confiabilidad, con el fin de modelar los procesos de falla/reparo y las funciones de costo asociados, cuando el sistema coherente es observado bajo una filtración completa.PALABRAS CLAVE: Modelo general de tiempo de vida, reparo mínimo, semi-martingala regular, sistema coherente, tasa de falla.ABSTRACT: In this paper is introduced some applications of the optimal stopping rule known as ILA rule (Infinitesimal Look Ahead rule) in solving optimization problems in maintenance, burn-in and guarantees processes on coherent systems observed at the level of components.

“…Stefanka and Hayakawa [7] evaluated the warranty costs over the warranty period under non-renewing free replacement policy over the life cycle of the product. Kim and Murthy [8] studied the expected warranty cost for products sold with free replacement warranty with varying usage intensity. Chattopadhyay and Murthy [9] developed probabilistic models to compute the expected warranty cost to the manufacturer when the items are sold with free replacement or pro-rata warranties.…”

Extended warranty pricing considering the time of money

Warranty usually plays an important role in providing customers with product assurance. Although the customers have to pay extra money to buy an extended warranty, they can obtain more protections from the company. Our study focuses on the extended warranty; the successive failure times of the repairable product are assumed to be drawn from a non-stationary Poisson process, taking into the consideration of time value of money, to figure out a more precise model of warranty cost. A numerical example is given to illustrate the model.
