HOLONIC PRODUCTION SYSTEM TO OBTAIN FLEXIBILITY FOR CUSTOMER SATISFACTION
2008
The Holonic Production System (HPS) can be a valid choice to overcome the problems of traditional production sys-tems’ architectures, thanks to its capability to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination. The HPS is made of holons seen as functional production units which are simultaneously autonomous and cooperative. Although the holonic approach could represent a valid solution in order to pursue the necessary levels of agility of production systems, they have been scarcely implemented in practice and even less studied from a business studies perspective. The purpose of this discussion paper is to show the bene…
Temporary organisations in the creation of dynamic capabilities: effects of temporariness on innovative capacity and strategic flexibility
2020
The dynamic capabilities (DCs) of an organisation refer to its ability to integrate and renew existing competences as circumstances may change. Although research has considered various aspects of D...
Context Aware Mobile Learning as a Factor for Economic Growth
2015
Abstract Mobile technologies have become an integral tool for communication and information delivery. It transformed educational paradigms from traditional one-size-fits-all to personalized and context aware learning. Such education can support human resources development, resulting in improved outcomes. Quality of education and working skills are the important driving force for economic development. This paper deals with the role of mobile learning in education, which is unique in terms of flexibility of time and location, but it requires extra planning and analyses of appropriate technologies during learning design process. The contextual information can be static, but some parts are dyna…
Determinants of employee well-being in project work
2021
Projects are supposed to foster innovation and flexibility and to create better conditions for learning. Accordingly, project work usually has a positive connotation for both, firms and the individ...
Process support in MetaCASE: implementing the conceptual basis for enactable process models in MetaEdit+
2002
This study concerns the support of information system analysis and design process in a metaCASE environment. We see a process as highly, evolutionary and unstructural in nature, thus requiring the tailorability of user process models and their conceptual basis, process modelling language (PML). In addition to the flexibility needed for guiding various system developers, the CASE environment needs to be enacted using strictly defined environment actions. A distinction between user and environment processes is made, hence distinguishing also their conceptual basis and modelling requirements. The study depicts the realisation of the basic concepts and tools required in modelling a PML and the …
New Flexible Probability Distributions for Ranking Data
2015
Recently, several models have been proposed in literature for analyzing ranks assigned by people to some object. These models summarize the liking feeling for this object, possibly also with respect to a set of explanatory variables. Some recent works have suggested the use of the Shifted Binomial and of the Inverse Hypergeometric distribution for modelling the approval rate, while mixture models have been developed for taking into account the uncertainty of the ranking process. We propose two new probabilistic models, based on the Discrete Beta and the Shifted-Beta Binomial distributions, that ensure much flexibility and allow the joint modelling of the scale (approval rate) and the shape …
Real-Time Routing Selection in Flexible Manufacturing Systems
1993
Routing flexibility is one of the main peculiarities of Flexible Manufacturing Systems. This paper proposes three methods for real-time routing selection. The first one makes decisions comparing the current workload of machines in each alternative path. The second method considers the current workloads at the bottleneck machines in each allowed route. The third approach makes real-time decisions minimizing a merit index that represents a measure of the still required resource amount. The index is computed by short discrete-event simulation runs. Some case studies evaluate and compare the proposed approaches.
Sustainability in Polish Road Transport Sector
2013
Abstract Today, road transport is the fastest-growing segment of the freight transport in Poland. Due to its dynamic development in the 90's and low barriers to entry of new transport companies the importance of this segment still growing. Low transport rates, the ability to reach every place, as well as high flexibility and reliability of supplies carried are the main advantages of this kind of transport. However, besides the advantages, road transport has disadvantages as well, and the biggest drawback of this type of transport is its negative impact on the environment through the emission of pollutants into the atmosphere. In addition, road transport is characterized by high land consump…
Lightweight Privacy-aware yet Accountable Secure Scheme for SM-SGCC communications in smart grid
2011
Abstract Smart grid is envisioned as a critical application of cyber-physical systems and of the internet of things. In the smart grid, smart meters equipped with wireless sensors can upload meter readings (data) to smart grid control and schedule centers via the advanced metering infrastructure to improve power delivery efficiency. However, data gathered in short intervals, such as 15 minutes, will expose customers' detailed daily activities (for example, when they get up and when they use oven) using nonintrusive appliance load monitoring. Thus, data must be hidden to protect customers' privacy. However, data accountability is still required for emergency responses or to trace back suspec…
Autonomous on-board data processing and instrument calibration software for the SO/PHI
2018
The extension of on-board data processing capabilities is an attractive option to reduce telemetry for scientific instruments on deep space missions. The challenges that this presents, however, require a comprehensive software system, which operates on the limited resources a data processing unit in space allows. We implemented such a system for the Polarimetric and Helioseismic Imager (PHI) on-board the Solar Orbiter (SO) spacecraft. It ensures autonomous operation to handle long command-response times, easy changing of the processes after new lessons have been learned and meticulous book-keeping of all operations to ensure scientific accuracy. This contribution presents the requirements a…
