TL;DR: In this article, a holistic life cycle costing approach for cost management in product development is described, and a systematic way to optimize capital and operational cost drivers is explained based on cost modeling, a case study performed with an industry partner demonstrates the application of the model.
Abstract: Optimizing cost drivers is one of the key success factors within product development. Approaches to develop cost-efficient products are deeply rooted in standard design methodology. However, in most instances manufacturing costs are in primary focus. Against the background of current trends in various industries, the life cycle of a product becomes more and more important, which results in the necessity of considering costs from the use phases as well. Designing a product with low life cycle costs poses a significant challenge. Various dependent influences lead to trade-off decisions with the involvement of subject matter experts. Focus on the most important cost influences in different life cycle phases is essential for a fast, efficient, and standardized process to optimize costs. This paper describes a holistic life cycle costing approach for cost management in product development. Based on cost modeling, a systematic way to optimize capital and operational cost drivers is explained. Relations and trade-offs between costs from different phases of the life cycle are presented. Also, a case study performed with an industry partner demonstrates the application of the model.

TL;DR: In this article, a case study on an international multidisciplinary team of postgraduate students working on a design project with an integrated product development (IPD) approach was conducted.
Abstract: Integrated Product Development (IPD) is comprehensively discussed in literature. The human-centered approach offers a parallelized set of work activities in interdisciplinary teams. Due to the rapid globalization of IPD activities in the companies, project members are often obliged to work remotely in teams and through virtual means of communication. However, with the recent shift towards working remotely in IPD teams new challenges have emerged that might adversely affect the success of IPD projects. The objective of the paper is to outline the key factors strengthening and weakening the IPD process in a remote multidisciplinary team environment. To fulfill the objective, a case study on an international multidisciplinary team of postgraduate students working on a design project with an IPD approach, was conducted. The results highlight key success factors and their contributions to the project success in a remote multidisciplinary team environment. Additionally, key weaknesses of such approach and their negative impacts are also indicated.

TL;DR: The use of LCC has been used by the Malaysia Government as a tactical tool in assessing alternatives being considered in the line of the Government objectives, to advise and facilitate the Government in planning and managing the newer approaches and techniques of project delivery system, i.e. public private partnership (PPP), value management (VM), facilities management (FM), sustainable building, industrialised building, and the Red Book procurement system of the government-linked companies (GLCs) as discussed by the authors.
Abstract: LCC has been mandated by the Malaysia Government as a tactical tool in assessing alternatives being considered in the line of the Government objectives, to advise and facilitate the Government in planning and managing the newer approaches and techniques of project delivery system, i.e. Public Private Partnership (PPP), Value Management (VM), Facilities Management (FM), sustainable building, the Industrialised Building Systems (IBS) and the Red Book procurement system of the Government-Linked Companies (GLCs). The Government and clients, including estimators, and researchers have seen the important use of LCC analysis to facilitate them in making better investment decisions to attain the most optimum total ownership cost of an asset.

TL;DR: In this article, a life cycle cost-benefit analysis approach is presented to identify the most suitable life extension strategy for ageing offshore assets by taking into account all the capital, installation, operational, maintenance and risk expenditures during the extended phase of operation.
Abstract: Purpose A substantial number of production assets in the offshore oil and gas industry are facing operation beyond their anticipated design life, thus necessitating a service life extension program in the future. Selection of the most suitable strategy among a wide range of potential options to extend the lifetime of equipment (e.g. re-using, reconditioning, remanufacturing, refurbishing and adding on safety/process control measures) remains a challenging task that involves several technical, economic and organizational complexities. In order to tackle this challenge, it is crucial to develop analytical tools and methods capable of evaluating and prioritizing end-of-life strategies with respect to their associated costs and quantifiable benefits. The paper aims to discuss these issues. Design/methodology/approach This paper presents a life-cycle cost-benefit analysis approach to identify the most suitable life extension strategy for ageing offshore assets by taking into account all the capital, installation, operational, maintenance and risk expenditures during the extended phase of operation. The potential of the proposed methodology is demonstrated through a case study involving a three-phase separator vessel which was constructed in the mid-1970s. Findings The results from the application case indicate that the capital expenditure (CapEx) accounts for the largest portion of life cycle cost for the replacement strategy, while risk expenditure (RiskEx) is the major contributor to costs associated with life extension. A sensitivity analysis is also conducted to identify factors having the greatest impact on the optimum life extension solution, including oil price, production rate and money interest rate. Practical implications In the past, the decisions about life extension or replacement of in-service equipment were often made in a qualitative way based on experience and judgment of engineers and inspectors. This study presents a “quantitative” framework to evaluate and compare the costs, benefits and risks associated with life extension strategies and subsequently to select the best strategy based on benefit/cost ratios. Originality/value To the best of authors’ knowledge, no studies before have applied life cycle assessment and cost-benefit analysis methods to prioritize the potential life extension strategies in the oil and gas industry sector. The proposed approach not only assists decision makers in selecting the most suitable life extension strategy but also helps duty holders reduce the costs corresponding to life extension execution.
