Warranty service providers usually provide homogeneous warranty to improve consumer satisfaction and market share. Considering the difference of consumers, some scholars have carried out studies on maintenance strategies, pricing, payment method, claim behaviour cost analysis in recent years. However, few focused differentiated coverage that considers usage rate option consumers. On basis previ...

Age replacement policy is concerned with finding an optional time tominimize the cost, at which time the unit is replaced even if itdoes not fail. So far, age replacement policy involving random agehas been proposed. This paper will assume the age of the unit is anuncertain variable, and find the optimal time to replace the unit.

An effective warranty servicing strategy should be made considering both warranty cost and product availability. Based on the two-dimensional free repair warranty, a strategy combining the imperfect preventive maintenance and minimal repair is proposed where the imperfect preventive maintenances are implemented in a special subregion of the warranty and all other failures are repaired minimally...

Recent years have seen a strong trend toward outsourcing warranty repair services to outside vendors. In this paper we consider the problem of dynamically routing warranty repairs to service vendors when warranties have priority levels. Each time an item under warranty fails, it is sent to one of many service vendors for repair. Items covered by higher priority warranty receive higher priority ...

Battery electric vehicles (BEV) are widely regarded as crucial to decarbonising the transport sector and achieving Paris Agreement goals. Yet, there is much political controversy over how accelerate uptake of BEVs, which currently still rather slow in most countries. The important concerns extent consumer-oriented policy measures, such purchase price subsidies, tax breaks subsidised charging in...

This paper studies the joint optimization of price and two-dimensional (2-D) warranty policy with limits both length usage. For this purpose, in paper, we first propose a new sales function to characterize influence price, length, usage limit on rate while considering heterogeneous customer rate. Then, model dynamic 2-D as nonlinear optimal control problem, solve it via numerical approach based...
