Environmental Life Cycle Costing - Chapter 6

Tóm tắt Một cuộc khảo sát được phân phối và thống kê phân tích, tại điểm khởi đầu của những cuộc thảo luận của các nhóm làm việc SETAC-Châu Âu, với mục đích xác định các thực tiễn hiện tại liên quan đến hàng không giá rẻ. Các characterizations có thể đã được thực hiện dựa trên việc phân tích được trình bày trong tài liệu này, do đó, gốc rễ của 3 loại cuối cùng của hàng không giá rẻ được phân biệt trong cuốn sách này. 33 trường hợp, phần lớn trong số đó đã được thực hiện. | 6 A Survey of Current Life Cycle Costing Studies Andreas Ciroth Karli Verghese and Christian Trescher Summary A survey was distributed and statistically analyzed at the outset of the deliberations of the SETAC-Europe working group with the aim of identifying current practices in regard to LCC. The characterizations that were made possible based on the analysis presented herein were therefore the roots of the ultimate 3 types of LCC that are distinguished in this book. The 33 cases the majority of which were performed in 2003 or later were statistically examined in terms of their goal and scope as well as the duration of the costing the type of sector and the functional unit. The results are distinguished according to the geographical location of the study or production site. The means by which the various investigators examined uncertainty are discussed. 6.1 INTENTION When performing LCC studies numerous goal and scope settings are possible. These shall ideally be reflected in the approach and methods used in the studies as well as in the result provided by the cases. In order to understand the current practice a survey was distributed at the outset of the 3-year period leading up to this book. The specific goals were to identify for the LCC in the public domain different goal and scope settings and various methods and methodological choices. The correlation between the various stated objectives with the methods employed was also examined. This process could be regarded as a descriptive step. A 2nd deliverable of the survey was to make recommendations regarding the most suitable means to carry out LCC. Indeed the survey inspired the delineation of the 3 types of LCC that are described herein and defined in Chapter 1. It should be emphasized that the aim of this chapter is not to build a collection of cases but rather to provide an analysis of life cycle costing studies undertaken for different use patterns in addition to identifying possible flaws and improvement .
