Development of a systematic approach to the implementation of modern information technologies in manufacturing enterprises

Smagowicz Justyna, Szwed Cezary

Production Engineering Archives

2024

Vol. 30, Iss. 1

36--47

The paper aims to show the possibilities of using modern information technologies in production management. Successive stages of production process preparation and implementation are characterized. Information technologies that are currently being implemented in manufacturing enterprises are discussed. The focus was on the part of the process related to the product's manufacture. The paper presents the concepts of two methodological approaches to the adoption of modern information technologies: the top-down approach and the bottom-up approach. The successive stages of each of these approaches are discussed. The advantage of the top-down approach is the ability to comprehensively implement various technologies, and the disadvantage is the significant level of resource commitment. The advantage of the bottom-up approach is the high efficiency of the proposed solution, and the disadvantage is the limitation of application to projects of limited size. The proposed approaches have been verified using the example of two companies: the automotive and the control automation industries. There are correlations between the choice of the methodology used and the type and extent of implementation of the technology in question. The study's key conclusion is that both approaches are applicable in practice. The most important thing in the decision-making phase is to identify the barriers and constraints related to the organization's maturity to use a given technology. Enterprises can use the study results to help them prepare for their digital transformation.

The market model of CDO spreads

Gątarek D., Petrov V., Stavrou A.

2015

Vol. 44, no. 1

149--162

In this paper we present a new arbitrage-free bottomup model of correlated defaults, based on a special approach to systematic and idiosyncratic risks for individual obligors. The model admits several attractive features, like consistency with currency and interest rate models, as well as numerical tractability and ﬂexibility, making it capable to ﬁt the market for practically all self consistent CDO tranche prices. Its background is rather remote from other approaches, like copulas and point processes, so our presentation is detailed.
