Abstract

Defines life cycle costing, which gives rise to Life Cycle Cost (LCC). Defines LCC as “The total cost of the system or product under study over its complete life cycle or the duration of the period of study, whichever is the shorter”. Stresses that LCC can be used at whatever level is chosen (estate or, say, a boiler). Explains the timing and mechanism of measurement. Argues that the application of LCC at an early design stage will greatly enhance system design and operation. Offers other pertinent definitions.

Abstract

Purpose

Reliability analysis is required to identify the components or subsystems with low reliability for a given designed performance. Life cycle cost analysis helps understand the cost implications over the entire life span of a product. The purpose of this paper is to present a case study describing reliability analysis and life cycle cost optimization of a band saw cutting machine manufactured and used in India.

Design/methodology/approach

The data required for reliability analysis is collected from the manufacturer and users of band saw cutting machine. The parameters of failure distribution have been estimated by using ReliaSoft’s Weibull++6 software. The life cycle cost is divided into various cost elements such as acquisition cost, operation cost, failure cost, support cost and net salvage value.

Findings

The results of the analysis show that the components such as band wheel bearing, guide roller bearing, limit switch, carbide pad, hydraulic cylinder oil seal, control panel dial, control panel and solenoid valve are critical from reliability and life cycle cost analysis perspective.

Originality/value

With certain design changes it is found that the reliability of the system is increased by 15.85 percent while the life cycle cost is reduced by 22.09 percent. The study also shows that the reliability analysis is useful for deciding maintenance intervals.

Abstract

Purpose

Despite existing life cycle costing (LCC) method descriptions and practicable suggestions for conducting LCC analyses, no systematic analyses on actual implementations of LCC methods exist. This paper aims to review reports on LCC applications to provide an overview of LCC uses and implementation feasibility.

Design/methodology/approach

A review of LCC cases reported in academic and practitioner literature. Case reports were compared against one another and against the defining articles in the field.

Findings

Most of the reported LCC applications were far from ideal. Compared to the methods suggested in the literature many of the case study applications: covered fewer parts of the whole life cycle, estimated the costs on a lower level of detail, used cost estimation methods based on expert opinion rather than statistical methods, and were content with deterministic estimates of life cycle costs instead of using sensitivity analyses.

Research limitations/implications

This review is limited to reported LCC applications only. Further research is encouraged in the form of a field‐based multiple‐case study to reveal context‐specific dimensions of LCC analysis and implementation challenges in more detail.

Practical implications

This review highlights the difficulty of conducting a reliable LCC analysis, and points out typical problems that should be carefully considered before drawing conclusions from the LCC analysis.

Originality/value

First systematic analysis of LCC applications that gives directions for further research on the LCC concept.

Abstract

Purpose

To provide an overview of research published in the management accounting literature on methods for cost management in new product development, such as a target costing, life cycle costing, component commonality, and modular design.

Methodology/approach

The structured literature search covered papers about 15 different cost management methods published in 40 journals in the period 1990–2013.

Findings

The search yielded a sample of 113 different papers. Many contained information about more than one method, and this yielded 149 references to specific methods. The number of references varied strongly per cost management method and per journal. Target costing has received by far the most attention in the publications in our sample; modular design, component commonality, and life cycle costing were ranked second and joint third. Most references were published in Management Science; Management Accounting Research; and Accounting, Organizations and Society. The results were strongly influenced by Management Science and Decision Science, because cost management methods with an engineering background were published above average in these two journals (design for manufacturing, component commonality, modular design, and product platforms) while other topics were published below average in these two journals.

Research Limitations/Implications

The scope of this review is accounting research. Future work could review the research on cost management methods in new product development published outside accounting.

Originality/value

The paper centers on methods for cost management, which complements reviews that focused on theoretical constructs of management accounting information and its use.

Abstract

Purpose

In recent years, fast urban expansion in China has stimulated rapid energy consumption growth and increased environmental pollution. Therefore, it is important to utilize clean and renewable energy in district heating for the sustainable urban development. This study aimed to investigate the environmental and economic impacts of one hot dry rock (HDR) geothermal energy-based heating system in a life cycle framework.

Design/methodology/approach

By using the input–output-based life cycle analysis model, the energy consumption, CO2 emission and other pollutants of the HDR-based heating system were evaluated and then compared with those of other four heating systems based on burning coal or natural gas. The life cycle costs of the HDR-based heating system were also analyzed.

Findings

The results showed that using HDR geothermal energy for heating can significantly reduce fossil fuel consumption, CO2 emission as well as environmental pollution, and its life cycle costs are also competitive.

Originality/value

This study not only evaluated the environmental and economic impacts of the HDR-based heating system in a life cycle framework but also provided a methodological life cycle assessment framework that can estimate both economic and environmental benefits, which can be used in policy making for China’s urban development.

Abstract

Purpose

The paper provides an overview of research published in the innovation and operations management (IOM) literature on 15 methods for cost management in new product development, and it provides a comparison to an earlier review of the management accounting (MA) literature (Wouters & Morales, 2014).

Methodology/approach

This structured literature search covers papers published in 23 journals in IOM in the period 1990–2014.

Findings

The search yielded a sample of 208 unique papers with 275 results (one paper could refer to multiple cost management methods). The top 3 methods are modular design, component commonality, and product platforms, with 115 results (42%) together. In the MA literature, these three methods accounted for 29%, but target costing was the most researched cost management method by far (26%). Simulation is the most frequently used research method in the IOM literature, whereas this was averagely used in the MA literature; qualitative studies were the most frequently used research method in the MA literature, whereas this was averagely used in the IOM literature. We found a lot of papers presenting practical approaches or decision models as a further development of a particular cost management method, which is a clear difference from the MA literature.

Research limitations/implications

This review focused on the same cost management methods, and future research could also consider other cost management methods which are likely to be more important in the IOM literature compared to the MA literature. Future research could also investigate innovative cost management practices in more detail through longitudinal case studies.

Originality/value

This review of research on methods for cost management published outside the MA literature provides an overview for MA researchers. It highlights key differences between both literatures in their research of the same cost management methods.

Abstract

Purpose

The purpose of this paper is to present the durability analysis in predicting the reliability life cycle for an automobile crankshaft under random stress load using the stochastic process. Due to the limitations associated with the actual loading history obtained from the experimental analysis or due to the sensitivity of the strain gauge, the fatigue reliability life cycle assessment has lower accuracy and efficiency for fatigue life prediction.

Design/methodology/approach

The proposed Markov process embeds the actual maximum and minimum stresses by a continuous updating process for stress load history data. This is to reduce the large credible intervals and missing loading points used for fatigue life prediction. With the reduction and missing loading intervals, the accuracy of fatigue life prediction for the crankshaft was validated using the statistical correlation properties.

Findings

It was observed that fatigue reliability corresponded well by reporting the accuracy of 95–98 per cent with a mean squared error of 1.5–3 per cent for durability and mean cycle to failure. Hence, the proposed fatigue reliability assessment provides an accurate, efficient, fast and cost-effective durability analysis in contrast to costly and lengthy experimental techniques.

Research limitations/implications

An important implication of this study is durability-based life cycle assessment by developing the reliability and hazard rate index under random stress loading using the stochastic technique in modeling for improving the sensitivity of the strain gauge.

Practical implications

The durability analysis is one of the fundamental attributes for the safe operation of any component, especially in the automotive industry. Focusing on safety, structural health monitoring aims at the quantification of the probability of failure under mixed mode loading. In practice, diverse types of protective barriers are placed as safeguards from the hazard posed by the system operation.

Social implications

Durability analysis has the ability to deal with the longevity and dependability of parts, products and systems in any industry. More poignantly, it is about controlling risk whereby engineering incorporates a wide variety of analytical techniques designed to help engineers understand the failure modes and patterns of these parts, products and systems. This would enable the automotive industry to improve design and increase the life cycle with the durability assessment field focussing on product reliability and sustainability assurance.

Originality/value

The accuracy of the simulated fatigue life was statistically correlated with a 95 per cent boundary condition towards the actual fatigue through the validation process using finite element analysis. Furthermore, the embedded Markov process has high accuracy in generating synthetic load history for the fatigue life cycle assessment. More importantly, the fatigue reliability life cycle assessment can be performed with high accuracy and efficiency in assessing the integrity of the component regarding structural integrity.

Abstract

The objective of this life cycle environmental cost analysis (LCECA) model is to include eco‐costs into the total cost of the products. Eco‐costs are both the direct and indirect costs of the environmental impacts caused by the product in its entire life cycle. Subsequently, this LCECA model identifies the feasible alternatives for cost‐effective, eco‐friendly parts/products. This attempts to incorporate costing into the life cycle assessment (LCA) practice. Ultimately, it aims to reduce the total cost with the help of green or eco‐friendly alternatives in all the stages of the life cycle of any product. The new category of eco‐costs of the cost breakdown structure includes eight eco‐costs, namely cost of effluent/waste treatment, cost of effluent/waste control, cost of waste disposal, cost of implementation of environmental management systems, costs of eco‐taxes, costs of rehabilitation (in case of environmental accidents), cost savings of renewable energy utilization, and cost savings of recycling and reuse strategies. Development of a suitable cost model and the identification of the feasible alternatives are performed simultaneously. Various checklists based on multiple environmental criteria will be used to ensure the eco‐friendly nature of the alternatives. On the basis of the calculated environmental impact indices (EII), priorities will be made for the selection of suitable alternatives. The mathematical model of LCECA aims to define the relationships between the total cost of products and the various eco‐costs concerned with the life cycle of the products, and determine quantitative expressions between the above‐said costs. A computational LCECA model has been developed to compare the eco‐costs of the alternatives. This model will include a break‐even analysis to evaluate the alternatives, and sensitivity analysis and risk analysis modules. This model aims at a cost‐effective, eco‐friendly product as an end result. This LCECA model will be compatible with the existing LCA software tools.
