PENGGUNAAN SIMULASI UNTUK PEMECAHAN MASALAH TRANSPORTASI
No full textSecara umum sebagian besar masalah transportasi darat yang sering terjadi adalah, kemacetan lalu lintas, trayek-trayek yang tumpang tindih, volume pelayanan tidak sesuai dengan jumlah penumpang serta efisiensi yang rendah. Dengan melakukan simulasi melalui komputer untuk masalah transportasi tersebut, yakni dengan parameter jumlah antrian, menentukan waktu keberangkatan bus (headway) pada shelter keberangkatan, dapat ditentukan jumlah armada bus yang optimal untuk suatu trayek tertentu, dapat ditentukan penjadwalan bus dan sebagainya. Makalah ini mendeskripsikan usaha penentuan jumlah bus yang optimal pada perencanaan busway kota Yogyakarta. Pada model awal yaitu sistem dengan jadwal keberangkatan bus pada menit ke-0, ke-5, ke-10, ke-25 dan seterusnya, diperlukan 18 bus yang memiliki kapasitas penumpang perhari 15.352. Model alternatif 1 dengan jadwal keberangkatan bus setiap 5 menit berkapasitas 21.812 penumpang per hari. Pada model alternatif 2 dengan jadwal keberangkatan bus pada menit ke-0, ke-5, ke-10, ke-18 dan seterusnya, kapasitas penumpang perhari 20.140. Sedangkan pada model alternatif 3 dengan jadwal keberangkatan bus setiap 3 menit, kapasitas penumpang perhari mencapai 31.996
Supply Chain Simulation for Determining Quantity of Delivery Bach
No full textSupply chain planning problems encompass industrial production process design and improvement,
inventory control policy, transportation management, supply procurement, and demand planning. The
supply chain is due to a realization by most companies that maximizing performance of one department
or function may lead to less than optimal performance for the whole company. In order to achieve high
performance, supply chain functions must operate in an integrated and coordinated manner. As the modern
high technology manufacturing systems can be extremely complex due to factors such as: multiple
part types made in the same facility/line, numerous manufacturing, batch processing, multiple levels of
subassemblies, just to name a few. The uncertainties in the supply chain network make manufacturing
enterprises inefficient. The supply chain management should be concerned with the reduction or even
elimination of uncertainties. Simulation is a practical methodology for understanding the high-level dynamics
of a complex manufacturing system
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
