Traditional Approaches

This paper presents a review of research in the area of life cycle costing and offers a critique of current commercial cost estimation systems. The focus of the review is on relevant academic research on life cycle cost from 2000 onwards. In addition to this a comparison of the current cost estimation systems is presented. Using the review findings and industrial investigations as a base, a set of mathematical representations for design and manufacturing costs and the introduction of the critical factors is proposed. These are considered in terms of the operational, maintenance and disposal costs to create a method for ascertaining the life cycle cost estimate for complex products. This is presented using as an exemplar, research currently being undertaken in the area of low volume and long life electronic products in the UK defence sector. The benefit of the method proposed is that it aims to avoid the inflexibility of traditional approaches which usually require historical and legacy data to support the cost estimation processes.

And Control

The Illinois Department of Transportation (IDOT) spends $2 million annually on reflective crack control treatments; however, the cost-effectiveness of these treatments had not been reliably determined. A recent study evaluated the cost-effectiveness of IDOT reflective crack control System A, which consists of a nonwoven polypropylene paving fabric, placed either in strips longitudinally over lane-widening joints or over the entire pavement (area treatment). The study was limited to projects constructed originally as rigid pavements and subsequently rehabilitated with one or more bituminous overlays. Performance of 52 projects across Illinois was assessed through crack mapping and from distress and serviceability data in IDOT’s condition rating survey database. Comparisons of measured reflective cracking in treated and control sections revealed that System A retarded longitudinal reflective widening crack development, but it did not significantly retard transverse reflective cracking, which agrees with earlier studies. However, both strip and area applications of these fabric treatments appeared to improve overall pavement serviceability, and they were estimated to increase rehabilitation life spans by 1.1 and 3.6 years, respectively. Reduction in life-cycle costs was estimated to be 4.4 and 6.2 percent when placed in medium and large quantities, respectively, and to be at a break-even level for small quantities. However, life-cycle benefits were found to be statistically insignificant. Limited permeability testing of field cores taken on severely distressed transverse joints suggested that waterproofing benefits could exist even after crack reflection. This was consistent with the observation that, although serviceability was generally improved with area treatment, crack reflection was not retarded relative to untreated areas.

Costing Analysis

This study was conducted in order to estimate the economic life of two models of rubber-tired skidders, namely Timberjack 450C and HSM 904, in Iranian Caspian forests. The total annual costs and average cumulative cost of skidders were calculated by life-cycle costing analysis. The economic life of the machines was estimated by both the cumulative cost model and cost minimization model. The results indicated that the economic life of Timberjack 450C and HSM 904 is 7,700 h (at the end of the 11<sup>th</sup> year) and 15,300 h (at the end of the 17<sup>th</sup> year), respectively, using the cost minimization model. Furthermore, the results indicated that the economic life of Timberjack 450C and HSM 904 is 9,100 h (at the end of the 13<sup>th</sup> year) and 11,900 h (at the end of the 21<sup>st</sup> year), respectively, using the cumulative cost model. The cumulative cost model estimated the economic life of skidders longer than the cost minimization model.

Costing Analysis

This work investigates life cycle costing analysis as a tool to estimate the cost of hydrogen to be used as fuel for Hydrogen Fuel Cell vehicles (HFCVs). The method of life cycle costing and economic data are considered to estimate the cost of hydrogen for centralised and decentralised production processes. In the current study, two major hydrogen production methods are considered, methane reforming and water electrolysis. The costing frameworks are defined for hydrogen production, transportation and final application. The results show that hydrogen production via centralised methane reforming is financially viable for future transport applications. The ownership cost of HFCVs shows the highest cost among other costs of life cycle analysis.

The Cost

Life cycle cost estimates of training equipment for F-16 Avionics Intermediate Station personnel were developed. The major purpose was to compare the cost of intermediate level maintenance training when conducted on simulated vs actual avionics test equipment. This was the initial phase of a planned two-part effort. The analysis was therefore limited to estimates of training device acquisition and maintenance costs. Total estimated fifteen year costs for simulated equipment trainers were approximately 50% less than comparable estimates for actual equipment trainers.

The Cost

In order to survive in today’s competitive global business environment, implementation of life cycle costing methodology with a greater emphasis on cost control could be one of the convincing approaches for the manufacturing firms. The product life cycle costing approach can help track and analyse the cost implications associated with each phase of product life cycle. Life cycle costing (LCC) practices with traditional costing methods may provide results that have a severe deviation from the real product LCC as it focuses on the cost of materials, labor and a low portion of overheads apportioned by the absorption rate to the product. Activity based costing (ABC) has emerged as one of the several innovative and more accurate costing methods in recent years. It is based on the principle that products or services consume activities and activities consume resources that generate costs. Thus, the ABC system focuses on calculating the costs incurred on performing the activities to manufacture a product. This paper presents a LCC modeling approach for estimating life cycle cost of pumps using activity based costing method. The study was conducted in a large pump manufacturing company from India that has significant global standing within its industry. Firstly, all the activities and cost drivers associated with the life cycle of a pump have been identified. A methodology for LCC analysis using ABC is then developed and it is applied to two different pumps manufactured by the same industry and the results obtained are presented.

Over Time

Basing drug reimbursement on cost-effectiveness provides too little incentives for R&D. The reason for this is that cost-effectiveness is concerned with immediate value for money. But since the price of a drug usually declines over time, the drug might well provide value for money as seen over its entire life cycle, even though its price during patent protection is too high to warrant reimbursement according to the cost-effectiveness decision rule. We show in a theoretical model that welfare could be improved if decision-makers took a longer perspective and initially allowed higher prices than immediate value for money can motivate. We also discuss the real world relevance of applying dynamic cost-effectiveness.
