Research Questions

Many organizations have adopted ERP systems, but most of them are not aware of the total costs associated with them, and they only consider the costs related with the software acquisition. This article is an exploratory study that sets out to identify other costs related to ERP systems during their life-cycle. Through the different phases of the life-cycle we define and categorize the various costs. The costs were classified as tanglible and intangible. We also describe a case study where the costs related to the three initial phases of the life-cycle were analyzed: acquistion, implementation, and usage and maintenance. Finally, some conclusions are drawn and we pose some research questions for further work.

A physical asset’s health is the consequence of a series of factors, ranging from the characteristics of the location where it operates to the care it is submitted to. These characteristics can influence the durability or the horizon of the useful life of any equipment, as well as determine its operational performance and its failure rates in the future. Therefore, the assessment of the influence of asset health on Life Cycle Costs is a compelling need. This paper proposes the incorporation of a factor that reflects the projected behavior of an asset’s health index into its corresponding Life Cycle Costing (LCC) model. This allows cost estimates to be made more realistic and LCC models to be operated more accurately. As a way of validating this proposal, a case study is shown. The methodology proposed in this case study was applied in a real case, considering an LNG facility located in central Chile. In addition, sensitivity studies and comparisons with the results obtained by a traditional Life Cycle Costing model are included. The results show the usefulness of incorporating asset health aspects into the Life Cycle Costing of physical assets.

The Cost

Life-cycle cost analysis (LCCA) is a commonly used approach by pavement engineers to compare the economic efficiency of alternative pavement design and maintenance strategies. Over the past two decades, the pavement community has augmented the LCCA framework used in practice by explicitly accounting for uncertainty in the decision-making process and incorporating life-cycle costs not only to the agency but also to the users of a facility. This study represents another step toward improving the LCCA process by focusing on methods to characterize the cost of relevant pay items for an LCCA as well as integrating costs accrued to users of a facility caused by pavement–vehicle interaction (PVI) and work zone delays. The developed model was implemented in a case study to quantify the potential implication of both of these components on the outcomes of an LCCA. Results from the construction cost analysis suggest that the proposed approaches in this paper lead to high-fidelity estimates that outperform current practice. Furthermore, results from the case study indicate that PVI can be a dominant contributor to total life-cycle costs and, therefore, should be incorporated in future LCCAs.

The approach used to implement an ERP system is an important decision in its implementation project as it greatly affects the configuration of the system, the allocation of resources and the management of the project and its risks. It will also play a decisive role at all the stages of the ERP system’s life cycle. This chapter discusses the different ways of “going-live” of ERP systems: big-bang, small-bangs and implementation in phases, and describes their advantages and disadvantages. The chapter also presents results of an exploratory study made in 53 Brazilian companies, which implemented SAP R/3. Based on these results, influences of the companies’ characteristics and of the project on the selected method are discussed. The relation of the implementation approach and project time is also presented.

Buoyancy Control

A case study approach clearly demonstrates how to integrate various investigative methods with design, procurement, contracting and construction strategies to significantly reduce life cycle costs for a recently constructed operating pipeline. Emergent strategies based on lessons learned throughout the process are presented based on an after construction review.
