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.

Hierarchical Sales Forecasting System for Apparel Companies and Supply Chains

Lenort R., Besta P.

Fibres & Textiles in Eastern Europe

2013

Vol. 21, no. 6 (102)

7--11

The typical problems facing with apparel companies and supply chains are forecasting errors, because fashion markets are volatile and difficult to predict. For that reason, the ability to develop accurate sales forecasts is critical in the industry. There are several research studies related to forecasting apparel goods, but very often only for one level. However, apparel companies and supply chains deal with a number of levels at which the forecasts could exist and require consistent forecasts at all of them. The paper presents a hierarchical middle-term forecasting system designed for this purpose on the basis of a literature review. The system is built by the top-down forecasting approach and verified by means of a case study in a particular apparel company. The weaknesses of the system are identified during discussion of the results acquired. A generalised concept of the ANN forecasting model is designed for elimination these weaknesses.

Rynki mody są niestabilne i trudne do przewidzenia, dlatego typowym problemem, z którym muszą się uporać firmy odzieżowe dla konstrukcji odpowiednich łańcuchów dostaw to przewidywanie błędów. Z tego powodu, możliwość opracowania dokładnej prognozy sprzedaży jest bardzo istotna w przemyśle. Istnieje wiele badań naukowych dotyczących prognozowania dla towarów odzieżowych, ale bardzo często dotyczą tylko jednego poziomu. Jednak firmy odzieżowe i łańcuchy dostaw mają do czynienia z dużą liczbą poziomów i wymagają spójnych prognoz na wszystkie z nich. Przedstawiono hierarchiczny system średnioterminowego prognozowania przeznaczony do tego celu. System zbudowano przez odgórne podejście prognozowania i zweryfikowano poprzez studium przypadku w danej firmie odzieżowej. Słabości systemu zostały określone podczas dyskusji uzyskanych wyników. Uogólnione pojęcie modelu prognozowania przeznaczone jest do eliminacji słabości.
