Design at the root of biophilia. Imitation. Nature
2021
According to the current state of research on the phenomenon of biophilia, the positive influence of nature's elements on humans has long been widely understood. Since the negative impact of urbanised areas on quality of life was noticed, human-friendly architecture has been redefined, where the physical and mental well-being of people using buildings, remains highly dependent on their contact with the environment. Selected examples of existing buildings analyzed two different approaches to contemporary biophilic architecture; one where nature is the pedestal of the whole building and one where the interpretation of nature translates into technological, engineering or structural solutions. …
Facility layout problem: Bibliometric and benchmarking analysis
2019
Facility layout problem is related to the location of departments in a facility area, with the aim of determining the most effective configuration. Researches based on different approaches have been published in the last six decades and, to prove the effectiveness of the results obtained, several instances have been developed. This paper presents a general overview on the extant literature on facility layout problems in order to identify the main research trends and propose future research questions. Firstly, in order to give the reader an overview of the literature, a bibliometric analysis is presented. Then, a clusterization of the papers referred to the main instances reported in literat…
Collaborative writing with web 2.0 technologies: education students' perceptions
2011
Published version of an article from the journal: Journal of Information Technology Education. Also available from the publisher: http://jite.org/documents/Vol10/JITEv10IIPp073-103Brodahl948.pdf Executive Summary Web 2.0 technologies are becoming popular in teaching and learning environments. Among them several online collaborative writing tools, like wikis and blogs, have been integrated into educational settings. Research has been carried out on a wide range of subjects related to wikis, while other, comparable tools like Google Docs and EtherPad remain largely unexplored in the literature. This work presents a case study investigating education students' perceptions of collaborative writ…
The Last Planner System Style of Planning: Its Basis in Learning Theory
2012
The objective of this article is to contribute to creating a better understanding of the Last Planner System (LPS) - which is associated with Lean Construction - in the light of the learning processes at the basis of knowledge development, and of change and innovation. Founded on a theoretical discussion, three research questions are asked, namely: In what ways can the LPS be expected to alter the learning arenas compared to conventional project management in construction; according to learning theory, what are the main challenges associated with implementing the LPS; and, finally, what kind of learning can be linked to an implemented LPS that functions as intended? The implementation of th…
Comparison of Internal Clustering Validation Indices for Prototype-Based Clustering
2017
Clustering is an unsupervised machine learning and pattern recognition method. In general, in addition to revealing hidden groups of similar observations and clusters, their number needs to be determined. Internal clustering validation indices estimate this number without any external information. The purpose of this article is to evaluate, empirically, characteristics of a representative set of internal clustering validation indices with many datasets. The prototype-based clustering framework includes multiple, classical and robust, statistical estimates of cluster location so that the overall setting of the paper is novel. General observations on the quality of validation indices and on t…
Managing adoption by cultural development: Exploring the plant level effect of a ‘Company Specific Production System’ (XPS) in a Norwegian multinatio…
2020
Purpose: ‘Company Specific Production Systems’ (XPS) aim to adopt ‘best practice’ across plants within a company. A pertinent issue in the literature involves the constraints in the possibilities of realising such an adoption. This paper addresses to what extent and how a Norwegian multinational succeeded in adopting the XPS in its local plants. Design/methodology/approach: A Brazilian, Chinese and Norwegian plant of a Norwegian electro-chemical company were studied from 2017 to 2019. Our data consist of the results of the plant’s assessment performance program, combined with interviews and observations at different organizational levels. Findings: The MNC had largely managed to adopt the X…
Firefly algorithm based upon slicing structure encoding for unequal facility layout problem
2019
Finding the locations of departments or machines in a workspace is classified as a Facility Layout Problem. Good placement of departments has a relevant influence on manufacturing costs, work in process, lead times and production efficiency. This paper analyses the problem of allocating departments with restrictions in terms of unequal area and rectangular shape within a facility, in order to minimize the sum of material handling costs taking into account the satisfaction of the aspect ratio requested. In particular, we propose for the first time a Firefly Algorithm based on the slicing structure encoding. The proposed method was tested comparing the results obtained from other authors on t…
Not so different altogether: Putting Lean and sociotechnical design into practice in a process industry
2021
Purpose: The shop-floor organization under lean production (LP) has been hotly debated for about three decades. As this organization concept leaves considerable room for interpretation, the content of lean-inspired changes can vary widely. This paper pleads for a contingency view of how LP is implemented and how the outcomes of lean-inspired changes rely on users’ interpretations of the concept in particular production contexts.Design/methodology/approach: A case study was conducted in two large Norwegian chemical plants. Data from the observations and interviews were supplemented by interviews with top managers in 2017 and 2018. The first author also followed a management audit in one plan…
EFFECTS OF THE PENETRATION OF WIND POWER IN THE BRAZILIAN ELECTRICITY MARKET
2016
Climate variability has been the main driver for renewables in the Brazilian electricity market. This article analyzes the vulnerabilities of the dependence on hydropower in renewable energy production due to climate variation, as well as wind power penetration in Brazil, given a set of wind industry policies. Despite Brazilian renewable energy increase, the study shows the impact in energy supply in north region, due to the lack of transmission infrastructure. In Brazil, the potential trade-offs between renewables growth, and transmission infrastructure inconsistencies in terms of policy implementation are not yet well analyzed. Simulation results show the potential conflicts between energ…
Special Issue on Computational Intelligence and Nature-Inspired Algorithms for Real-World Data Analytics and Pattern Recognition
