Supply chain risk assessment in the fashion retail industry: An analytic network process approach
No full textIn today’s global markets, characterized by extremely fast changes in technology and customer’s demand, and by product life cycle getting shorter and shorter, a single firm has not the ability to be competitive if it is not included in a network that, operating as a single entity, is able to react to demand dynamism and volatility. Therefore, existing supply chains, structured in a global sourcing view, are highly vulnerable to perturbations resulting from a strong dependence on other network’s players, such as suppliers or logistics providers. In this complex and competitive context, properly assessing and managing risks connected to the different stages of the value chain, as well as external and not directly controllable risks, means being able to ensure continuity in supply. This paper focuses on the particular field of the fashion retail industry since its highly unpredictable demand and extremely short life cycle make it very important to analyse risks connected to the supply chain. The particular case we are referring to is represented by a fashion company that manages an extended network of wholesalers, direct operated stores, franchising mono-brand stores and factory outlet stores main aim of the presented work is to prioritise the list of identified risk factors by adopting the Analytic Network Process approach. This method is, in fact, more suitable for real complex problems that cannot be completely represented through a simple hierarchical structure. The obtained results show that supply chain efficiency, in terms of correct management of both material and informative flows, is considered the most crucial part also for a demand-driven supply chain as the fashion industry one which, in addition, is constantly seeking for customer tastes and always changing trends
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
Optimisation of the replenishment problem in the Fashion Retail Industry using Tabu-Bees algorithm
No full textThe problem of properly allocating several different products in the stores network is one of the crucial processes in the Retail Industry. This means trying to meet market demand and at the same time reducing logistics costs. In this context, main aims of the presented work are to (a) otpimise the replenishment process for the retailer's network of companies with multi-product multi-store configuration and (b) propose a new algorithm which combines the Basic Bees algorithm, a swarm based optimization technique, with the Tabu-Search principles. Attention is focused on the particular case of lost sales and budget constraints for a fashion company. Simulation results show that the use of the Tabu-Bees algorithm can guarantee an average 10% improvement in results allowing the model to overcome local minima
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
