Purpose: The purpose of this article was to assess changes and trends in the main parameters characterizing inventory management in industrial processing enterprises in 2006-2009, 2010- 2013 and 2018-2022. Design/methodology/approach: The analysis covered business entities by Divisions of Section C - “Manufacturing” in relation to four crisis situations. The research undertaken is descriptive, spatial-temporal and critical analysis - the changes and deviations of selected indicators from average values in periods of prosperity are indicated. The presentation of the research results includes descriptive form and graphical form in the form of figures. The numerical data came from the Statistics Poland website. Findings: In the majority of manufacturing enterprises, all crisis situations had an adverse effect on inventory management. The exceptions were D17, D21 and D32 enterprises, which showed no negative sensitivity to crisis situations. Research limitations/implications: The geopolitical and macroeconomic situation has impeded most of the favorable trends after the post-pandemic “rebound” in 2022. For this reason, it was difficult to clearly assess the impact of the energy crisis on inventory management at the surveyed companies. Originality/value: The originality of the study lies in the fact that it was carried out for four different crisis situations and was concerned with assessing changes in the parameters characterizing inventory management, rather than assessing the value of indicators.

Controlling the size of inventories in a manufacturing company allows, firstly, to reduce costs, secondly, to increase profits, and thirdly, to relieve the burden on working capital. In practice, the approach and indicators chosen by companies for inventory management and planning often turn out to be ineffective, which may subsequently cause problems related to lack of funds for settlements with suppliers, lack of warehouse space, the possibility of losing important customers, and the like. The combination of all such problems can lead to the bankruptcy of a company. Inventory control is a complex process that should be improved. The aim of the research work was to analyze inventory management and develop directions for improving and increasing the efficiency of the inventory control system of a selected company from the construction industry. The article characterizes the activities of the analyzed company, and an analysis of inventory control was carried out, during which problems related to this process were revealed. As part of the project, three groups were distinguished in terms of rotability of finished beam-type products. As a result, recommendations for solving the existing shortcomings were proposed for each group.

In this study, we analyze how a company's inventory policy changes because of adopting CSR policies in the manufacturing companies listed on the Shanghai Shenzhen stock exchange by targeting manufacturing companies, as their overall policies are greatly impacted by the level of inventory. The analysis focus on how inventory policies affect Chinese companies' CSR. Inventory levels affect company policies therefore we chose manufacturing companies. The uniqueness of the topic warranted us to research CSR and Inventory management from historical and current viewpoints. The topic has few investigations, especially in China. Increased worker, consumer, and environmental satisfaction may impact volume, according to this study. Given the uniqueness of the topic, there are a very limited number of studies conducted on the topic, especially in the Chinese context, which warrants us to conduct the study, keeping in view the historical and present perspectives of both CSR and Inventory management. In this study, we take this step further by examining whether the volume is affected by efforts to improve the satisfaction of staff, consumers, and the natural environment. We found that customer satisfaction positively affects the cost-to-sales ratio. Environmental consciousness harms the ratio, and employee satisfaction has an inverted U-shaped association with this ratio. It was also found that customer satisfaction positively correlates with inventory levels. Our research has shown that increased levels of social responsibility led to decreased levels of customer corporate social responsibility and increased levels of CSR, which explains the non-linear relationship between a company's total CSR and the to-sales ratio. According to the collected data, the ratio of profits to sales tends to increase when a company's CSR rating is much higher (or lower) than the mean of the CSR distribution.

W niniejszym badaniu analizujemy, jak zmienia się polityka firmy w zakresie zapasów w związku z przyjęciem polityki CSR w spółkach produkcyjnych notowanych na giełdzie w Szanghaju i Shenzhen. Skoncentrowano się na spółkach produkcyjnych, ponieważ ich profil działania i ogólna polityka ma duży wpływ na poziom zapasów. Analiza koncentruje się na tym, jak polityka dotycząca zapasów wpływa na CSR chińskich firm. Wyjątkowość tematu skłoniła nas do zbadania CSR i zarządzania zapasami z historycznego i aktualnego punktu widzenia. Temat ten obejmuje niewiele badań, zwłaszcza w Chinach. Zgodnie z niniejszym badaniem zwiększona satysfakcja pracowników, konsumentów i środowiska może mieć wpływ na wielkość produkcji. Biorąc pod uwagę wyjątkowość tematu, istnieje bardzo ograniczona liczba badań przeprowadzonych na ten temat, zwłaszcza w kontekście chińskim, co uzasadnia przeprowadzenie badania, biorąc pod uwagę historyczne i obecne perspektywy zarówno CSR, jak i zarządzania zapasami. W niniejszym badaniu poszliśmy o krok dalej, sprawdzając, czy wysiłki na rzecz poprawy satysfakcji pracowników, konsumentów i środowiska naturalnego mają wpływ na wielkość sprzedaży. Okazało się, że zadowolenie klientów pozytywnie wpływa na stosunek kosztów do sprzedaży. Świadomość ekologiczna szkodzi temu wskaźnikowi, a zadowolenie pracowników ma związek z tym wskaźnikiem w kształcie odwróconej litery U. Stwierdzono również, że zadowolenie klientów pozytywnie koreluje z poziomem zapasów. Nasze badania wykazały, że zwiększony poziom odpowiedzialności społecznej doprowadził do zmniejszenia poziomu społecznej odpowiedzialności biznesu klientów i zwiększenia poziomu CSR, co wyjaśnia nieliniowy związek między całkowitą CSR firmy a wskaźnikiem sprzedaży. Zgodnie z zebranymi danymi, stosunek zysków do sprzedaży ma tendencję wzrostową, gdy ocena CSR firmy jest znacznie wyższa (lub niższa) niż średnia rozkładu CSR.

Background: The decision-making process in the operational context of enterprises is an integral aspect of how they function, and in this area, precise demand forecasting plays a key role. The use of accurate forecasting models not only meets customer expectations but also enables efficient resource allocation and operational cost optimization. In the long term, such actions contribute to increasing the organization's competitiveness in the market. In recent years, there has been a growing trend in the use of advanced analytical technologies, including machine learning, for demand forecasting purposes. This scientific paper focuses on a comparative analysis of demand forecasting effectiveness using the generative language model GPT in relation to the auto ARIMA algorithm. Methods: A case study analysis for a selected manufacturing organization was conducted based on twelve diversified operational references, for which the supply chain mechanisms are heterogeneous. In the research process, a classification into four reference groups was established, based on the time required to complete the ordering process. Forecast generation was carried out using the auto.arima() algorithm in the R programming environment, as well as through the ChatGPT language model versions 3-5. The forecast results were subjected to comparative analysis, in which weighting was applied for different forecast accuracy indicators, including the Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and the number of precisely predicted daily forecasts. Results: The study showed that ChatGPT is more reliable in forecasting compared to ARIMA. However, integrating ChatGPT into the existing systems in the company can be problematic, mainly due to limitations in data operations. Despite this, ChatGPT has the potential to improve the accuracy of inventory management plans both in the short and long term. Conclusions: The comparative analysis of the effectiveness of forecasting models, including ChatGPT and ARIMA, showed that the ChatGPT algorithm achieves higher levels of forecasting accuracy. This is observed despite increased computational complexity and challenges associated with processing large data sets.

Background: Circular supply chain management encourages manufacturers to take advantage of used materials and industrial wastes, ensuring social and economic benefits of enhanced environmental sustainability in production. With the development of digital technologies, transactions can be recorded within distributed or decentralized ledger technology. To improve the reliability of digital transactions on the internet, manufacturers need to apply security software such as blockchain technology across a network. Blockchain technology in the supply chains brings transparency, traceability, and security to online transactions, increasing customer attractiveness to the used product and recycling process. Secure transactions might bring significant benefits to the future of the retail industry. The manufacturer exploits the retailer as an online store. Consumers access an online store for purchase, return, and comment on the manufacturer's products. Methods: This research presents a novel meta-heuristic algorithm, specifically, adaptive particle swarm optimization (adaptive PSO), to determine the optimal policy for product price and quantity of materials imported from suppliers for maximizing total profits with sustainability. The adaptive PSO algorithm evaluates the fitness function involving discrete random variables. The supply chain model captures realistic conditions by considering the inherent uncertainties of customer demand. Two scenarios in business settings have been tested on the same customer demand. The proposed framework is intended to yield a more sustainable, resilient, and regenerative system, securing the data of the shared community. Results: The swarm intelligence algorithm implements profit optimization to determine the unit price of the product and the number of materials to be imported. The numerical experiments are conducted to demonstrate the efficacy of the optimal strategy and to evaluate the effect of the number of used products returned to the recycling center. An effective circular supply chain management is realized based on a secure database shared across a network of participants. Key findings significantly contribute to the intelligent decision support system for optimizing inventory management under various stochastic scenarios. Conclusions: Sharing, reusing, repairing, and remanufacturing help companies transition to a circular economy, minimize waste, diversify sources of supply, and maintain production continuity. Transactions on the blockchain framework become transparent and traceable. Based on the circular economy and blockchain platform, this study deals with an adaptive particle swarm optimization algorithm (APSO) to determine the optimal policy for product unit price and quantity of materials imported from suppliers to maximize total profits. The presented methodology can provide better supply chain visibility and traceability under highly realistic stochastic environments.

The literature on product variety provides great insights into various businesses. However, little research has been conducted on product variety in the healthcare industry. This study aims to explore the influence of product variety on inventory in hospitals. Since most hospitals are known to replenish products using a homegrown ad-hoc system, a model is developed for exploring all possible product combinations and substitutions. This article presents the behaviour of product substitution, which may be either one-to-one or many-to-one for both sterile and non-sterile products, in the hospital with cost factors. It discusses the product variety reduction and its corresponding cost impacts. The data on a hospital inventory over the course of six years has been procured from a hospital in Norway. Based on the results, the hospital could have a potential product variety reduction of approximately 11% and cost savings from the spending of approximately NOK 3.6 million. Reducing the variety of products in hospital inventories proves to be an approach to reducing costs. The model developed for the research.
