Analysis of the production function in civil construction: a driver for lean construction

The construction industry has bleen an important role for economic growth, and gains in productivity could produce a significative impact. However, historically, it has been proved that this industry is operating not significativelly well in terms of efficiency related performance. The objective of this work is to justify the adoption of Lean Construction, as a comprehensive alternative for addressing problems related to resource and systemic productivity. To frame the productivity problem, the work analyzes the productivity of this sector, using the production function of Cobb Douglas, which is an econometric concept that provides information to assess relationships between the total volume produced, and the resources that are used during the production process. The present work has analyzed biggest  companies in the world of civil construction, all of them listed in the Forbes 2017 publication. The production function analysis shows that these organizations are experiencing returns of decreasing scale. To address this results, this paper discusses the use of lean construction as a feasible alternative to increase productivity, considering the effects that operations networks and supply chain level could produce in the aggregate level of industry performance

Application of Lean Construction – A Systematic Literature Review

Traditional management models have not achieved good results for project management in the construction sector. In this sector, the benefits of a proper management can only be achieved through efficient models that offer better results for the end customer through more effective control of workflows, resulting in improved project performance and the elimination of non-value adding activities. This paper seeks to support three statements associated with these observations: (A1) management models with more effective control of workflows result in improved project performance; (A2) these models are able to eliminate non-value adding activities and consequently reduce waste in construction sites; and (A3) a structured planning provides the improvement of predictability, reliability, and contributes to the optimization of value adding activities, as well as to better communication, coordination and learning in construction projects. The research was based on a systematic review of the existing literature to demonstrate that the proposed statements have theoretical support and that it is possible to demonstrate that such statements are valid to describe aspects related to lean construction.

Lean Construction: IGLC research evolution and agenda for the future

The way Lean Construction has evolved within the construction industry is still not entirely clear. Inspired by lean manufacturing, there are differences in the output of the construction industry, thus resulting in differences between both types of sectors. In 2012, Jacobs, Folkestad, Glick have conducted a study analyzing the works published in the IGLC between 1996 and 2009. The authors have noticed a gap between Lean Construction and the Toyota Production System framework. In view of the high volume of publications between 2010 and 2016, as well as of the dynamics of the sector, this work proposed to reanalyze the 686 works published in this interval, and to verify whether there have been changes in the content of Lean Construction. It also proposes to map, within the proposed topics, the main topics studied each year through content analysis. Initially, the results obtained with the publication of 2012 have been compared, and it was possible to verify that certain topics remained, as was the case of work-on-process improvement. On the other hand, new topics have emerged and became frequent, such as the case of the Last Planner tool. Thereafter, a roadmap was drawn up by grouping the main topics covered each year by topic, allowing the understanding of the development of Lean Construction in the studied time interval

A Supply Chain Management view from ICPR – Innovation in Product and Production

This Special Issue of the Brazilian Journal of Operations and Production Management (BJOPM) features six papers selected from the supply chain management (SCM) track of the 21st International Conference on Production Research (ICPR), which conference theme was “Innovation in Product and Production”. This introduction paper evaluates and summarizes the selected contributions characterizing SCM with a leading role in innovation management. The research presented here focuses on supply chain design and cultural influences on supply chain performance, bridges the gap between basic research and industrial application and provides approaches to effectively design supply networks and processes. Some of the dominate key topics emphasized in the six papers contained in this special issue are countertrade in supply chains, types of contracts in supply chains, value stream mapping (VSM), process management, supply chain performance measurement, order penetration points and inventory policies for distribution systems. The main research tools used are analytical hierarchy process (AHP), simulation, SCM logistic scorecard and Markov chains

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Identifying organizational requirements for the implementation of Advanced Manufacturing Technologies (AMT)

a b s t r a c t AMT selection and adoption processes have been extensively studied. Topics that include financial and human factors, productivity, and coordination of the AMT implementation establish a substantial content of the present research agenda. The purpose of this paper is to study the organizational factors that influence the AMT implementation, considering a manufacturing strategy context and an analysis based on an organizational design framework. The research strategy is based on 'empirical iterations' using survey secondary data, experts' interviews information and multiple case studies. The results show that there is a set of recommendations, which strongly influence the AMT implementation. Companies require a structured and integrative approach for the AMT implementation in order to take advantage of all their individual and systemic benefits. The set of proposed AMT recommendations for integrating these technologies to the organizational design are framed by structural, process and contextual aspects
