“…Systems engineering principles implies that the AM system must normally have a strong influence over the acquisition phase of any asset given that usually this provides the greatest opportunity to control the life cycle cost and life cycle performance or system effectiveness of assets (Arnold and Lawson 2004;ISO/IEC 15288 2008;Blanchard 2009). The challenge in managing the entire asset life effectively lies in integrating the fragmented activities through the various stages (Charles and Alan 2005;Luan, Siew et al 2007). This leads to integrating the need identification, alternative analysis and project selection to the business management focus.…”

The role of engineering asset management (AM) system as a controlling element within organizations is not well defined or understood. The purpose of this paper is to include the role of AM in the organizational strategy making, an issue that has not received sufficient attention. The focus of the paper is on how such role is maintained by the AM system activities, relationships and mechanisms over the asset-related activities of an organization. Design/methodology/approach -As an approach, a reference framework is required that allows research of this area. By combining a number of possible views of an organizational management system a comprehensive view can be established. A review of literature was used to establish a framework identifying the AM system as an integrated part of the organization's management system. Findings -A framework is established that focuses on planning and controlling asset-related activities by involving a set of activities, relationships between these activities and feedback mechanisms. A system functional model is proposed integrating the established framework as part of the control of the enterprise system. Research limitations/ implications -The framework and system functional model are established on a theoretical basis and practical experience requiring applicability to be proven by further research. Practical implications -Asset managers in capital intensive organizations can utilize the framework and the system functional model in order to study their AM system, its relationships and to consider how it may be improved.

“…LCC is directly influenced by decisions and activities from system preliminary design to utilization stage including system analysis, evaluation of alternatives or trade-offs. LCC may be reflected by the costs committed to and/or being incurred during the asset life cycle (Blanchard and Fabryky, 2010, p. 585), because asset operational management including maintenance is carried out through the entire asset life (Charles and Alan, 2005;Luan, et al, 2007). El-Akruti (2012) argues that LCC analysis is essential in managing the overlaps among the interdisciplinary activities in assets' life cycle.…”

This paper focuses on developing maintenance policies for critical assets to improve the production performance based on life cycle cost (LCC) analysis. A general approach is adopted for conducting the LCC analysis. The investigation is based on a case study to demonstrate how an optimum maintenance policy is determined. The relevant LCC structure in the case study is defined for the decision process which involves determination of the optimum life, repair limit and selection of materials, and trade-off between repair and replacement. The LCC analysis is based on statistical data modelling which facilitates decision-making on the optimal replacement of an asset and its remaining life. Based on the optimization and remaining life criterion, the optimal maintenance policy can be made. The results obtained from this case study include selection of the best lining material for use, determination of the optimal time for refractory lining replacement, the hot repair sequence required for maintaining the optimum condition and the repair limit for doing cold repairs before replacement, for one type of electric arc furnaces used in the steel industry. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 This paper focuses on developing maintenance policies for critical assets to improve the production performance based on life cycle cost (LCC) analysis.

-Today, the power utilities is setting on the slow load growth and the aging of power equipment, and then could spend the efforts on the stability of system performance. Asset management may be defined as the process of maximizing corporate profit by maximizing performance and minimizing cost over the entire life cycle of power equipment. Therefore, asset management is great way to fulfill the economic investment and the stability of system performance. This paper presents the application of effective asset management from an economic perspective. A proposed method is considering the life cycle analysis using life cycle cost methodology for hydro-generator during the total life cycle. The life cycle cost methodology include a way to calculating maintenance and operating costs. The proposed method will be expected to play an important role in investment decision making considering economic evaluation.
