The role of cost breakdown structure in life cycle cost model

This paper highlights the basic process of developing a life cycle cost model and the role of cost breakdown structure for water distribution pipeline networks. a life cycle cost is the total cost of owning an asset during its predicted useful life,while a cost breakdown structure illustrates all the costs emerged in each single phase of the asset’s life cycle cost. its purpose is to identify,define and organize all cost elements to be taken into account in a life cycle cost. each cost element included in developing a cost breakdown structure will also be discussed in this paper. © 2015 penerbit utm press. all rights reserved.
