Challenges in the Business Model of Low-Cost Airlines
2020
In recent decades, low-cost airlines have proliferated in the European market offering cheap tickets and increasing popularity. This business model, characterised by cost leadership, has been studied on numerous occasions. The case of the Irish airline Ryanair has presented different challenges over the last few years in relation to its stakeholders, who are shaping the sustainability of the current era of air travel. This business model should be adapted to the current demands of the market, such as corporate social responsibility or care for the environment. The functioning of low-cost airlines regarding the use they make of ERP management systems is also analysed. They aim to balance the…
Finding evidence on the innovative or positional character in medium sized manufacturing firms
2002
Through an empirically based study on 65 medium sized manufacturing firms corresponding to 12 industrial sectors and located in the Spanish region of Valencia, we seek in this paper to provide enough evidence about the prevalence of positional, static and myopic values or, instead, innovative, dynamic and open minded principles, among the firms under study. Gathered into three groups of sectors, depending on the scope of demand (weak, medium and strong demand sectors), we conclude that the weak and medium demand sectors are still facing remarkable challenges basically connected to technology issues, despite improvement in other variables directly linked to an innovative character.
Performance and energy optimisation in CPUs through fuzzy knowledge representation
2019
Abstract This paper presents an automatic design space exploration using processor design knowledge for the multi-objective optimisation of a superscalar microarchitecture enhanced with selective load value prediction (SLVP). We introduced new important SLVP parameters and determined their influence regarding performance, energy consumption, and thermal dissipation. We significantly enlarged initial processor design knowledge expressed through fuzzy rules and we analysed its role in the process of automatic design space exploration. The proposed fuzzy rules improve the diversity and quality of solutions, and the convergence speed of the design space exploration process. Experiments show tha…
Social support for collaboration and group awareness in life science research teams
2019
Background Next-generation sequencing (NGS) technologies have revolutionarily reshaped the landscape of ’-omics’ research areas. They produce a plethora of information requiring specific knowledge in sample preparation, analysis and characterization. Additionally, expertise and competencies are required when using bioinformatics tools and methods for efficient analysis, interpretation, and visualization of data. These skills are rarely covered in a single laboratory. More often the samples are isolated and purified in a first laboratory, sequencing is performed by a private company or a specialized lab, while the produced data are analyzed by a third group of researchers. In this scenario, …
A formal model based on Game Theory for the analysis of cooperation in distributed service discovery
2016
New systems can be designed, developed, and managed as societies of agents that interact with each other by offering and providing services. These systems can be viewed as complex networks where nodes are bounded rational agents. In order to deal with complex goals, they require cooperation of the other agents to be able to locate the required services. The aim of this paper is formally and empirically analyze under which circumstances cooperation emerges in decentralized search of services. We propose a repeated game model that formalizes the interactions among agents in a search process where agents are free to choose between cooperate or not in the process. Agents make decisions based on…
Towards safe reinforcement-learning in industrial grid-warehousing
2020
Abstract Reinforcement learning has shown to be profoundly successful at learning optimal policies for simulated environments using distributed training with extensive compute capacity. Model-free reinforcement learning uses the notion of trial and error, where the error is a vital part of learning the agent to behave optimally. In mission-critical, real-world environments, there is little tolerance for failure and can cause damaging effects on humans and equipment. In these environments, current state-of-the-art reinforcement learning approaches are not sufficient to learn optimal control policies safely. On the other hand, model-based reinforcement learning tries to encode environment tra…
ERP system implementation in SMEs: exploring the influences of the SME context
2012
Small and medium-sized enterprises SMEs are increasingly implementing enterprise resource planning ERP systems. Compared to large enterprises, SMEs differ in a number of inherent characteristics, which are likely to impact the ERP system implementations. The purpose of this study is to explore these influences of the SME context on the ERP system implementation process. SME characteristics are synthesised from relevant literature and the influences of the contextual factors on various activities across the ERP life cycle are investigated. The study presents findings from a multiple case study of four SMEs. The ownership type of the companies and limited resources were identified as the most…
Evaluating security and privacy issues of social networks based information systems in Industry 4.0
2022
[EN] The present study aimed to analyse the main risks related to security and privacy of social networks based information systems in Industry 4.0. The methodology we used is an innovative exploratory data-driven process divided into three steps. First, we performed sentiment analysis to divide the database composed of 67, 206 tweets into feelings. Second, we applied a topic-modelling algorithm to extract topics. Third, we applied textual analysis to collect insights. A total of 10 topics related to security and privacy issues were identified as results. The paper concludes with a discussion of the challenges and main concerns related to the identified topics.
Diverging approaches to benefits realization from public ICT investments
2013
PurposeThe purpose of this paper is to explore practical methods for benefits realisation, with the intention of investigating if they are variance of a theme or rather can be classified as different approaches.Design/methodology/approachBased on a document study of Norwegian methods‐in‐use, this study uses an analytical comparison following an assimilation‐accommodation procedure to categorize the chosen methods as instances of approaches to benefits realisation.FindingsThis study documents the emergence of several methods from practice in the last half decade. This analysis suggests the existence of three distinct approaches to benefits realisation and defines these according to their cen…
Innovation capabilities in tourism and food production SMEs in the Baltic Sea Region
2011
Drawing on the resource-based view, this paper addresses two fundamental questions: what innovation capabilities are most important for the creation of innovations in Small and Medium-sized Enterprises (SMEs) and what are the relations between different innovation capabilities? We propose a model for the analysis of innovation capabilities in small and medium enterprises. In the model, we distinguish between capacities, such as access to financial, physical, technological and human resources, and competencies, such as knowledge and skills, market and entrepreneurial orientation. The findings are based on surveys from 277 tourism and food production SMEs from five Baltic Sea Region countries.
