Unsupervised KDD to creatively support managers' decision making with fuzzy association rules: A distribution channel application

To be competitive in contemporary turbulent environments, firms must be capable of processing huge amounts of information, and effectively convert it into actionable knowledge. This is particularly the case in the marketing context, where problems are also usually highly complex, unstructured and ill-defined. In recent years, the development of marketing management support systems has paralleled this evolution in informational problems faced by managers, leading to a growth in the study (and use) of artificial intelligence and soft computing methodologies. Here, we present and implement a novel intelligent system that incorporates fuzzy logic and genetic algorithms to operate in an unsupervised manner. This approach allows the discovery of interesting association rules, which can be linguistically interpreted, in large scale databases (KDD or Knowledge Discovery in Databases.) We then demonstrate its application to a distribution channel problem. It is shown how the proposed system is able to return a number of novel and potentially-interesting associations among variables. Thus, it is argued that our method has significant potential to improve the analysis of marketing and business databases in practice, especially in non-programmed decisional scenarios, as well as to assist scholarly researchers in their exploratory analysis.     

Artificial intelligence-based systems applied in industrial marketing: An historical overview,current and future insights

Intelligent systems have particular potentialities and strengths to support decisional situations faced by companies, especially those of a strategic nature, where good strategic intelligence is necessary. In this paper, we carry out an historical literature review of artificial intelligence-based systems applied to marketing, covering a time period of several decades (from the 1970s to the present day), with special focus on applications to industrial marketing. A detailed review is presented, along with conclusions and some future insights. Then, we briefly introduce the set of papers in this special issue.

ICT-enabled system innovations in public services: Experiences from intelligent transport systems

Public transport is confronted with major challenges such as climate change and congestion. This paper discusses how these major challenges are addressed by means of ICT-enabled system innovations in public services. Recent developments in ICT enable the realisation of novel solutions for public transport that can be subsumed under the headline of intelligent transport systems (ITS). However, while the advances in information and communication technology are very fast, the transformation of transport systems and infrastructures tends to take a long time. In parallel, public sector reforms of the past decade, often characterised by the introduction of New Public Management principles, have changed the organisational and institutional conditions for transport service provision and innovation, with the private sector playing an increasingly prominent role. Public–private innovation networks in services (ServPPINs) have been suggested as a concept to foster the realisation of system innovations.This paper analyses the conditions, determinants and instruments for managing ServPPINs successfully, by comparing four cases of ServPPINs in intelligent transport systems, which all aim at establishing system innovations. The four cases are: ITS Vienna Region, a dynamic intermodal traffic information service; compano, a novel ride-sharing scheme in Austria; SIS, a real-time traffic information services, displays and management system in Oslo; and Flexus, an electronic ticket system for public transportation in Oslo.The paper shows the importance of organisational and institutional conditions of ServPPINs for realising these system innovations, and the crucial role of entrepreneurial individuals, both in public and private sector organisations. It also points to the importance of making clear strategic choices at the right moments in time in the course of the life-cycle of ServPPINs.

A model for R&D performance measurement

R&D activities are increasingly costly and risky and, as a consequence, measuring their performance and contribution to value becomes critical. This paper illustrates a formal model for measuring R&D performance, based upon a balanced and synthetic evaluation of quantitative indicators from five different perspectives of performance: financial, customer, innovation and learning, internal business, alliances, and networks. The model is built in coherence with the suggestions coming from the theory of measurement in soft systems, which gives relevant guidelines for ensuring validity, objectivity and inter-subjectivity of the model. Then, an application in a real R&D setting is described, which helps to understand the model and to enlighten its main advantages and limits.

Critical success factors of Six Sigma implementations in Italian companies

The present paper discusses the results of a research project going on at Politecnico di Milano, aiming at analysing the idiosyncrasies of Six Sigma implementations in Italian companies. In particular, the project addresses the following research questions, regarding the approach of Italian companies towards Six Sigma: are Italian companies implementing Six Sigma exactly as it was originally conceived at Motorola or, rather, is there an Italian way to Six Sigma? do Italian companies which implemented Six Sigma recognize the same set of critical success factors singled out in the international literature?Bibliographic analysis showed a lack of literature concerning Six Sigma implementation in Italian companies. The research was then based on the study of real life application of Six Sigma in an Italian company and on discussion through a set of workshops organized at Politecnico di Milano with Six Sigma experts. In particular, we will concentrate on a set of case studies and on one workshop specifically addressing the second research question.The insights coming from the analysed case studies and discusses with industry experts - if further explored, validated and reorganized - could constitute a Road Map for Six Sigma implementation in Italian companies; the validation and re-organization process is still on-going and its completion could constitute a further research objective.     

Conceptualisation of technology education within the paradigm of sustainable development

This article addresses the issue of how sustainable development might be conceptualised and used to advance technology education practice. It is argued that a conceptualisation of sustainable development based on a combination of weak anthropocentrism and value based approaches within particular social, environmental and economic contexts provides the basis for establishing education for sustainable development (ESD) through technology education. It is argued that such an approach is in accord with the general push for a paradigm shift in curriculum development to meet future social needs. Moral values are proposed to be at the centre of teaching and learning in technology education. Examples of learning activities presented in the article illustrate the position and approach. A second issue addressed in the article concerns the role of teachers in the implementation of ESD. The argument advanced in the article, that this role is critical, is supported by the results of two research projects with in-service and pre-service teachers.
