When SMEs face the challenge of improving operations-related performances to survive: a theoretical framework and a survey in Italy
No full textThe objective of this paper consists in presenting a methodological framework to support the re-design decision, in terms of the strategic settlement in the operations management area and of the adoption level of innovative techniques. Furthermore, to test the ability of the proposed methodology to suggest re- designing patterns, more than 15 real-life case-studies of Italian SMEs are thoroughly considered and analysed
Modelling Plant Capacity and Productivity: The Multi-Machine Case
Get PDFThis study deals with systems (lines, departments or production units) made up of multiple machines, and it analyzes the meaning and assessment of productivity, utilization, efficiency and so
forth at system level. Special emphasis is placed on calculating indices for the whole system starting from parameters referred to a single machine. Two basic system types are discussed, i.e. pure parallel systems and pure serial systems. The latter ones are further split into serial systems with tightly interconnected machines (i.e. without buffers), serial systems with loosely interconnected machines (i.e. provided with some decoupling buffers among stages), and independent departments systems

No full textThis article introduces two real-life case studies respectively devoted to a parallel production system of a chemical company and to a production system made up of tightly interconnected machines. The objective is to highlight the most relevant features of a production system that determine the system's productivity. A calculation model that allows movement from machine-level to system-level indices is useful both during the production system design and during the performance measurement phase. The application of the presented framework provides useful results: (1) to improve analysis, and to make proper diagnosis of causes, of productivity loss and to track their evolution over the time; (2) to design and to implement specific improvement projects, aimed at removing loss causes, and thus increasing efficiency and productivity; (3) to establish proper production capacities, by focusing on bottleneck machines, to keep under control the actual system throughput; (4) to make comparisons and internal benchmarking aimed at defining machine management and productive maintenance best practices; (5) to design plant performance reporting systems and build appropriate tools to collect data from the field
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
