demand is assumed constant in the classical economic order quantity (eoq) model. however, in the real world, the demand is dependent on many factors such as the selling price, warranty of product and marketing effort. in addition pricing and ordering quantity decisions are interdependent for a seller when demand for the product is price sensitive in the inventory models. these types of models a...

For engineering and production systems, due to the structural dependence between components, disassembly operation caused by replacement of components will affect failure degradation processes other in system. In order optimize extended warranty (EW) cost multi‐component system with dependence, this paper described modeled impact, then rate model component considering impact under EW was develo...

This paper presents the effects of salvage value on the optimal age-replacement policy for non-repairable products sold with a renewing free-replacement warranty (RFRW). Cost models from the customer’s perspective are developed for both warranted, and non-warranted products. The corresponding optimal replacement ages are derived such that the long-run expected cost rate is minimized. Under the ...

In general, a newly purchased item or system is warranted for a specific period. When the system fails during the warranty period, it is repaired free of charge. Even if the system is repairable, there exists some warranty services under which the manufacturer replaces the failed system during the warranty period. This study considers a case where a manufacturer offers an additional warranty se...

Conditional Value-at-Risk Constrained Optimization of a Power Portfolio Published in International Journal of Applied Decision Sciences • A predictive and risk analytics tool guiding cash management of warranty reserves, covering contingent liabilities. • Finding a balance between excess reserves causing opportunity cost, and not enough reserves necessitating emergency funds. • The decision mak...

In this paper, a replacement-repair model is developed to study a warranty servicing policy for a class of multi-state deteriorating and repairable products, based on a computer simulation analysis. In each working state there is a determined probability for transition to each of the subsequent states, given that it has made a transition out of that state. There are two parameters that determin...

In systems today, software provides substantial portions of capability and performance. In many Department of Defense (DoD) acquisitions, however, software too often is a minor consideration when the early and most constraining decisions about program cost, schedule, and behavior are made (i.e., prior to Milestone A). These decisions manifest themselves in the acquisition strategy, the system a...
