Papel de los sistemas de control de gestión en el éxito de la trasformación digital: influencia en las capacidades dinámicas digitales
2023
La rápida evolución de las tecnologías de la información (TI) y sus aplicaciones empresariales está obligando a las organizaciones a realizar esfuerzos constantes para seguir siendo competitivas. La nueva economía digital, así como el entorno disruptivo y cambiante en el que operan las empresas, fuerza a los directivos a priorizar estratégicamente procesos de adaptación y transformación, replanteando su perspectiva estratégica más allá de la implantación de nuevas tecnologías (Rogers, 2016), para provocar un cambio profundo en toda la organización. Este proceso es conocido, aunque no siempre es bien entendido, como transformación digital (TD). La TD modifica el alcance y la velocidad del la…
Transient stability simulation of a fixed speed wind turbine by Matlab/Simulink
2007
This paper describes the dynamic behavior of a typical fixed speed wind turbine connected to the grid; the model is developed in the simulation tool Matlab/Simulink and created as a modular structure. The pitch control system is used for stabilization of the wind turbine at grid faults. In this way, voltage stability of the system with grid-connected wind turbines can be improved by using blade-angle control for a temporary reduction of the wind turbine power during a short-circuit fault in the grid. This paper shows a new variable control for maintaining of voltage stability, when a three-phase fault is applied close to the wind turbine and cleared by disconnecting the affected line. In th…
The Effect of the Perceived Utility of a Management Control System with a Broad Scope on the Use of Food Waste Information and on Financial and Non-F…
2020
The purpose of this study is to analyse the effect of the perceived utility of a management control system with a broad scope on the use of food waste information and on financial and non-financial performances in restaurants. To collect data, a questionnaire was administered in Brazilian restaurants. Data from 206 restaurants were analysed with structural equation modelling, which was performed with SmartPLS software. The results reveal that a management control system of broad scope, which includes non-financial information, is oriented towards the future, and contains an external and long-term focus, assists in the use of information on food waste. In addition, the use of information abo…

Toward learning autonomous pallets by using fuzzy rules, applied in a Conwip system
2012
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-4057-8 Nowadays, material planning and control strategies are becoming continuously complex tasks spanning from individual plants to logistic networks. In fact, this is the consequence of increasing intricacy in product variants and their respective convolution in networks’ structures. Customers ask for specific products with individual characteristics that force companies for more clever performances by more flexibility. For doing so, the existing planning and control systems, which work based on central m…
Fuzzy Systems Based on Multispecies PSO Method in Spatial Analysis
2012
We present a method by using the hierarchical cluster-based Multispecies particle swarm optimization to generate a fuzzy system of Takagi-Sugeno-Kang type encapsulated in a geographical information system considered as environmental decision support for spatial analysis. We consider a spatial area partitioned in subzones: the data measured in each subzone are used to extract a fuzzy rule set of above mentioned type. We adopt a similarity index (greater than a specific threshold) for comparing fuzzy systems generated for adjacent subzones.
The contribution of "spontaneous" health care networks to improving outcomes: Opportunities and challenges from the perspective of planning and contr…
2019
The article aims to explore how Planning Control systems may support network-oriented policy-making in the health care sector. This work examines the case of ISMETT (Mediterranean Institute for high specialized transplants and therapies), a Sicilian hospital established in 1998 to provide high specialized and complex transplants and therapies. ISMETT pertains to several networks and it has a long-time experience in establishing and governing such inter-organizational relationships. The analysis of the case illustrates how health care networks may contribute to improve health and generate social and economic outcomes for the community.
Iekšējās kontroles sistēma un tās novērtējums SIA “Firma Orions”
2018
Iekšējai kontroles sistēmai ir būtiska loma uzņēmuma efektīvas un normatīvajām prasībām atbilstīgas darbības nodrošināšanā. Mazos uzņēmumos izstrādātā iekšējās kontroles sistēma var būt nepilnīga, tās detalizācija – nepietiekama. Diplomdarba mērķis ir, pamatojoties uz teorētiskās informācijas izpēti un analīzi par iekšējās kontroles sistēmu, veikt SIA “Firma Orions” iekšējās kontroles sistēmas novērtējumu un izstrādāt atbilstošus priekšlikumus tās trūkumu novēršanai, uzlabošanai. Pētījumā tika vērtēta SIA “Firma Orions” iekšējās kontroles sistēma. Autore secina, ka tā izstrādāta daļēji. Nepieciešamos pasākumus tās trūkumu novēršanai un pilnveidošanai izstrādā atbilstošos priekšlikumos. Atsl…
Strategic thinking and accounting: potentials and pitfalls from a managerial perspective
2019
This study explores the strategic thinking of managers from an accounting perspective. By building on interview data from managers working with strategic roles in various organizations, an understanding is offered of the experienced potentials and pitfalls of accounting in strategic thinking. The results are elaborated into a framework presenting the dual nature of accounting in strategic contexts. This study suggests that the benefits and pitfalls of accounting for strategic thinking constitute a paradoxical duality, which cannot be fully solved, but must be addressed by practising managers. The observed role of accounting in managers’ strategic thinking also offers implications for manage…
Investing in strategic development : Management control of business model and managerial innovations
2018
Purpose This paper aims to explore management control in the strategic development of business model and managerial innovations. The issue is approached from the perspective of managerial work, aiming to outline what managers consider as essential elements of management control in these often iterative and learning-intensive developmental activities. Design/methodology/approach The study is based on the views of 20 managers engaged in strategic development and its control in various organisations. The interview data consist of the respondents’ experiences and project cases involving non-technological innovations. Qualitative content analysis is used to identify three key concepts of manage…
