This chapter deals with a mathematical model which gives an optimal production schedule in demand declining market if production system is imperfect (i.e. at any random time during production period machine shifts from 'in – control' state in to 'out – of control' state). This is a study about economic production in an imperfect production system. The imperfect production system means, a system...

A problem with most text production and language generation systems is that they tend to become rather verbose. This may be due to negleetion of the pragmatic factors involved in communication. In this paper, a text production system, COMMENTATOR, is described and taken as a starting point for a more general discussion of some problems in Computational Pragmatics. A new line of research is sugg...

In the past decades, the environment of production companies showed a permanent increase in dynamic and volatility in the form of demand fluctuations, new technologies or global crises. As a reaction to these new requirements, changeability of production systems came into attention. A changeable production system can adapt to these changes quickly and with little effort. Even though demand for ...

Open Journal Systems (OJS) is the result of a major research and development effort carried out under the auspices of the Public Knowledge Project (PKP) founded in 1998 by John Willinsky. OJS was developed to facilitate greater access to scholarly research by providing an open source platform for the production and distribution of the main coin of the academic research process, the scholarly jo...

Now with the Dept of CSEE, University of South Florida, Tampa, FL 33620 ([email protected]) Abstract — Modular hybrid timed Petri Nets are used to model and analyze behavior of random topology multioperational production systems. Each such system is decomposed into 3 fundamental modules, followed by derivation of their corresponding modular HPN models. The overall system model is obtained v...

We describe novel methods for highly adaptable representation of hypotheses about the complex temporal patterns typical of processes and threats. These methods permit expression and preservation of hypotheses about normal and abnormal processes of significant subtlety and complexity. The hypotheses can capture institutional domain knowledge and facilitate sharing across the organization. A hypo...

This paper introduces concepts for a service-oriented IT-landscape supporting flexible and high-performance provisioning of telecommunication products. On the one hand these concepts are designed to be generic in order to facilitate a short time-to-market for future products. On the other hand the concepts guarantee a scalable and high-performance operation of the system. The concepts have been...

Cattlemen have debated cow size and efficiency since the early days of the business. While efficient cattle production has been researched for over a century, it remains remarkably misunderstood. This misunderstanding can be costly for the industry as well as individual cattle operations because important and expensive management decisions are erroneously made based on misinformation or lack of...

Abstract—The paper deals with communication standards for control and production system. The authors formulate the requirements for communication security protection. The paper is focused on application protocols of the industrial networks and their basic classification. The typical attacks are analysed and the safety protection, based on requirements for specific industrial network is suggeste...

Nowadays, the skill management is an important factor in the new forms of the work organization. Man’s unlimited capacities are the main driving forces behind the evolution and the success of the Entreprise. the organization models have long been ignored , the human resources were considered as a secondary resources in the strategy of the company. Over the last years, however, the requirement t...
