Comparative analysis for estimating production costs

Estimating Building Construction Costs by Production Processes

Building actors need accurate estimates in order to efficiently undertake the construction of buildings. The knowledge of real expected costs of construction works is a necessary condition for contractors to submit competitive tenders and for developers to be aware of the magnitude of their investment. In this paper, an innovative process-based model is presented, the POP model. This model aims...

COMPARATIVE COSTS OF THE PRODUCTION, TRANSPORT AND ASSEMBLY STAGES OF PRESTRESSED PRECAST SLABS USING GENETIC ALGORITHMS

In the precast structures, optimization of structural elements is of great interest mainly due to a more rationalized way that elements are produced. There are several elements of precast prestressed concrete that are objects of study in optimization processes, as the prestressed joist applied in buildings slabs. This article inquires into cost minimization of continuous and simply supported sl...

Estimating Environmental Costs

Added demands on natural resources and proposed environmental regulations could potentially have a significant impact on the production and operational costs of information technology (IT). In this paper, we utilize an Economic Input-Output Life-Cycle Assessment (EIO-LCA) framework to model projected changes in the cost structure of a portfolio of IT products due to increased electricity prices...

Estimating Prevalence & Costs

Estimating medical costs

Abstract: Nonparametric estimators of the mean total cost have been proposed in a variety of settings. In clinical trials it is generally impractical to follow up patients until all have responded, and therefore censoring of patient outcomes and total cost will occur in practice. We describe a general longitudinal framework in which costs emanate from two streams, during sojourn in health state...
