A cost optimization-based design of precast concrete floors using genetic algorithms
(Elsevier B.V., 2012-03-01)
The integrated design optimization, not only the element optimization, is considered a strong trend. The integrated optimization involves the three major stages of an engineering design process namely conceptual design, ...

Feeder-trunk or direct lines? Economies of density, transfer costs and transit structure in an urban context
(Pergamon-Elsevier, 2016)
A feeder-trunk scheme has been labeled as superior in urban areas due to the presence of economies of density (decreasing average operating cost) along the avenues served by trunk lines. We compare this structure against ...
Hospital productivity bias when not adjusting for cost heterogeneity: The case of Spain
(2019)
This research quantifies the bias caused in hospital productivity measurements when cost heterogeneity is not considered. A multi-output stochastic cost frontier under a normalised translog specification is used to approximate ...
H-infinity design of switching surfaces for sliding-mode control with nonmatching disturbances

Análise de estruturas metálicas treliçadas por intermédio da aplicação do princípio do trabalhos virtuais
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2022-06-24)
This work presents an approach comparing a pre-existing low-carbon metal truss structure with this structure after the resizing process, mainly aiming at reducing material costs, given the high competition in this sector. ...
Comparativo orçamentário utilizando os sistemas construtivos convencional e Light Steel Framing
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2017-06-22)
With the national economic instability and the construction setor’s decline in recent years, it’s necessary to rationalize the productive processes of the sector. Therefore, one of the alternatives is the use of Light Steel ...
Labor incidents impact on tile cost structure in Colorificio Pordecar, C.A CompanyImpacto de las incidencias laborales en la estructura de costo de la baldosas de la empresa Colorificio Pordecar, C.A.

Are returns to scale with variable network size adequate for transport industry structure analysis?
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2006-08)
It is customary to analyze transport industry structure using two indices: (1) economies of density and (2) economies of scale with variable network size. The latter has been defined to analyze the behavior of costs when ...
