From supply chains to demand networks. Agents in retailing: the electrical bazaar
A paradigm shift is taking place in logistics. The focus is changing from operational effectiveness to adaptation. Supply Chains will develop into networks that will adapt to consumer demand in almost real time. Time to market, capacity of adaptation and enrichment of customer experience seem to be the key elements of this new paradigm. In this environment emerging technologies like RFID (Radio Frequency ID), Intelligent Products and the Internet, are triggering a reconsideration of methods, procedures and goals. We present a Multiagent System framework specialized in retail that addresses these changes with the use of rational agents and takes advantages of the new market opportunities. Like in an old bazaar, agents able to learn, cooperate, take advantage of gossip and distinguish between collaborators and competitors, have the ability to adapt, learn and react to a changing environment better than any other structure. Keywords: Supply Chains, Distributed Artificial Intelligence, Multiagent System.Postprint (published version

Benchmarking performance management systems
The Balanced Scorecard and associated performance management approaches, has become a widely practiced and popular management reporting method in recent times. Moreover, enabling technology, which assists in the delivery and personalisation of corporate performance information, is having a deeper and more rapid impact than ever before. This paper presents a brief comparative benchmarking study of leading enterprise performance management systems. Also, the author discusses the merits of bespoke internet technology development and out-of-the-box portal functionalities. An analysis of key business drivers and implementation risks of such approaches is highlighted via a case study example, and concludes the paper
Information technology and performance management for build-to-order supply chains
En las siguientes líneas se plantea un artículo de reflexión que tiene en cuenta parte del marco teórico que sustenta la investigación titulada “Prácticas pedagógicas que promueven la competencia argumentativa escrita (CAE) en niños campesinos de los grados
4° y 5° del Centro Educativo Municipal La Caldera, Sede Principal de Pasto”, desarrollada en el año 2012. En él se contemplan los aportes de las ciencias del lenguaje y la comunicación, la teoría de la argumentación, la didáctica de la lengua escrita y los géneros discursivos, que dan cuenta de la necesidad de desarrollar la
capacidad crítica en los estudiantes a través de la argumentación, lo cual implica transformar las prácticas pedagógicas para que se alejen de la transmisión de conocimientos y den paso a la comunicación, para que la palabra escrita sea apropiada de manera significativa
Risks associated with Logistics 4.0 and their minimization using Blockchain
Currently we are saying that we are at the dawn of the fourth revolution, which is marked by using cyber-physical systems and the Internet of Things. This is marked as Industry 4.0 (I4.0). With Industry 4.0 is also closely linked concept Logistics 4.0. The highly dynamic and uncertain logistic markets and huge logistic networks require new methods, products and services. The concept of the Internet of Things and Services (IoT&S), Big Data/Data Mining (DM), cloud computing, 3D printing, Blockchain and cyber physical system (CPS) etc. seem to be the probable technical solution for that. However, associated risks hamper its implementation and lack a comprehensive overview. In response, the paper proposes a framework of risks in the context of Logistics 4.0. They are here economic risks, that are associated e.g. with high or false investments. From a social perspective, risks the job losses, are considered too. Additionally, risks can be associated with technical risks, e.g. technical integration, information technology (IT)-related risks such as data security, and legal and political risks, such as for instance unsolved legal clarity in terms of data possession. It is therefore necessary to know the potential risks in the implementation process.Web of Science101857

On the Activity Privacy of Blockchain for IoT
Security is one of the fundamental challenges in the Internet of Things (IoT)
due to the heterogeneity and resource constraints of the IoT devices. Device
classification methods are employed to enhance the security of IoT by detecting
unregistered devices or traffic patterns. In recent years, blockchain has
received tremendous attention as a distributed trustless platform to enhance
the security of IoT. Conventional device identification methods are not
directly applicable in blockchain-based IoT as network layer packets are not
stored in the blockchain. Moreover, the transactions are broadcast and thus
have no destination IP address and contain a public key as the user identity,
and are stored permanently in blockchain which can be read by any entity in the
network. We show that device identification in blockchain introduces privacy
risks as the malicious nodes can identify users' activity pattern by analyzing
the temporal pattern of their transactions in the blockchain. We study the
likelihood of classifying IoT devices by analyzing their information stored in
the blockchain, which to the best of our knowledge, is the first work of its
kind. We use a smart home as a representative IoT scenario. First, a blockchain
is populated according to a real-world smart home traffic dataset. We then
apply machine learning algorithms on the data stored in the blockchain to
analyze the success rate of device classification, modeling both an informed
and a blind attacker. Our results demonstrate success rates over 90\% in
classifying devices. We propose three timestamp obfuscation methods, namely
combining multiple packets into a single transaction, merging ledgers of
multiple devices, and randomly delaying transactions, to reduce the success
rate in classifying devices. The proposed timestamp obfuscation methods can
reduce the classification success rates to as low as 20%
Shipbuilding 4.0 Index Approaching Supply Chain
The shipbuilding industry shows a special interest in adapting to the changes proposed by
the industry 4.0. This article bets on the development of an index that indicates the current situation
considering that supply chain is a key factor in any type of change, and at the same time it serves as a
control tool in the implementation of improvements. The proposed indices provide a first definition
of the paradigm or paradigms that best fit the supply chain in order to improve its sustainability and
a second definition, regarding the key enabling technologies for Industry 4.0. The values obtained
put shipbuilding on the road to industry 4.0 while suggesting categorized planning of technologies
