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.

PurposeThe purpose of this paper is to evaluate the accuracy of life cycle cost analysis (LCCA) for institutional (higher education) buildings as a predictor of actual realised facility costs.Design/methodology/approachResearch methodology includes a comprehensive literature review to identify issues, best practices and implementation of LCCA in the construction industry. A case study was conducted to evaluate the accuracy of LCCA in predicting facility costs.FindingsNotwithstanding the benefits of LCCA, its adoption has been relatively slow for institutional buildings. The case study revealed that the average difference between estimated and actual construction cost is 37 per cent, whereas the average difference between the actual and estimated maintenance cost is 48 per cent. There is an average difference of 85 per cent in the actual and estimated administration cost.Research limitations/implicationsWhile limited to a few buildings, the case study underscores that LCCA methods should not be used for cost predictions of facility performance but rather for comparing total costs of alternative building features and systems, as well as building types. Sensitivity analysis also revealed that the selection of a discount rate would have less impact on recurring costs estimates compared to non‐recurring cost estimates. Facilities managers' involvement in LCCA technique developments and implementations will likely improve its performance during programming phases.Practical implicationsThe value of LCCA procedures is limited as a predictor of actual realised facility costs. Educational institutions can use the methods described in this paper to replicate the study and arrive at their own conclusions regarding the LCCA techniques and their potential use in programming stages.Originality/valueThe paper evaluated the accuracy of LCCA for institutional buildings and the potential of LCCA as an asset management tool for institutional buildings and provided suggestions to improve its adoption in facilities management.

Broad Overview

In the context of increasing concerns for sustainable development new comprehensive methods are developed by builders and architects in order to reduce the environmental impact of buildings. Life Cycle Cost Analysis (LCCA) is one of these methods, perhaps the most functional one for the evaluation process. Using this LCCA contributes to the integration of the design process and helps identify opportunities for energy efficiency, such as appropriate zoning, natural lighting and design optimization of heating, ventilation and air conditioning (HVAC). It also helps in finding the best solutions for reducing overall costs. LCCA is very little known in Romania and quasi unused practice for building design and for this reason the present paper contains a broad overview of the methodology and it’s uses highlighting its main advantages and a case study of the building design intended for laboratory research. The analyzed building is one of the 12 identical buildings of Transilvania University Research and Development Institute from Brasov.
