Replacing equipment is an important decision that nearly all entities must face, generally
motivated by rising operating and maintenance costs of current assets or the technological …

Classical spare parts inventory models assume that the same vintage of technology will be
utilized throughout the planning horizon. However, asset replacement often occurs in the …

Operational characteristics of equipment tend to worsen due to ageing and wear. Physical
wear leads to an increase in the number of breakdowns and increases in current …

In many ecodesign problems, finding solutions that complete the design requirements while
bettering multiple performances (environmental impacts, costs, etc.) is no trivial task. Design …

The infinite-horizon cost minimization and the real-option stopping problem are used to
analyze serial replacement of a single asset under improving technology. It is shown that …

The economic life (EL) method of asset replacement is analyzed under improving
technology that impacts the maintenance cost, new asset cost, and salvage value. In …

This paper studies the cost-minimizing serial asset replacement problem under changing
operating and replacement costs. Technological improvements affect these costs in different …

Strategic business plans are based upon assumptions of future wood costs. Future wood
costs are affected by future equipment cost inputs and technological change. Equipment …

In this article, one of the commonly used replacement decision methods, the challenger–
defender (CD) method, is modified. The proposed method is shown to outperform the …

The paper analyzes a profit-maximizing serial replacement problem under variable asset
productivity, operating cost, and replacement cost that depend on asset age and installation …
