A large number of products are now being sold with long-term warranty policies. This is mainly due to fierce competition in the market and customer demand. Offering long term warranty results in additional complexities in estimating costs associated with warranty servicing due to the uncertainties associated with usage, preventive maintenance and warranty servicing strategies. This paper review...

OBJECTIVES Diesel exhaust fumes emission is a significant source of ultrafine particles, the size of which is expressed in nanometers. People occupationally exposed to diesel exhaust particles include mainly workers servicing vehicles with engines of this type. This article presents the analysis of measurements of ultrafine particle concentrations occurring in the bus depot premises during the ...

In contrast to the standard capital structure theory prediction that builds on a trade-o¤ between interest tax shields and expected bankruptcy costs, public …rms use debt quite conservatively. To address this well known debt conservatism puzzle (Graham 2000), I argue that servicing debt drains valuable liquidity for a …nancially constrained …rm and hence endogenously creates ‘debt servicing cos...

The objective of this study is to develop a warranty servicing strategy, based on imperfect and minimal repairs, that minimises the total warranty servicing cost. For pre-specified degrees of repair, the expected warranty servicing cost is minimised by optimally partitioning a two-dimensional rectangular warranty region into n disjoint subregions. We numerically illustrate the imperfect repair ...

This paper examines the impact of foreign aid on public sector fiscal behaviour in Côte d’Ivoire. A special interest is the relationship between aid, debt servicing and debt, given that Côte d’Ivoire is a highly indebted country. The theoretical model employed differs from those of previous studies by highlighting the interaction between debt servicing and the other fiscal variables. This model...

Space robotics has been considered one of the most promising approaches for on-orbit services (OOS) such as docking, berthing, refueling, repairing, upgrading, transporting, rescuing, and orbit cleanup. Many enabling techniques have been developed recently and several technology demonstration missions have been completed. Several manned servicing missions were also successfully accomplished but...

The study develops a model from which an option-adjusted spread approach is utilized for pricing individual mortgage servicing contracts. The pricing model is comprised of a stochastic interest rate process, an exogenous prepayment function and an assumed servicing cost, all of which jointly determines the contract’s future net cash flows and the rate at which to discount these cash flows. Then...
