DEMAND FORECASTING METHODS FOR SPARE PARTS LOGISTICS FOR AVIATION: A REAL-WORLD IMPLEMENTATION OF THE BOOTSTRAP METHOD

One of the critical issues that an airline faces in its day-to-day operations is a correct prognosis of the necessary quantity of spare parts that are continuously fed into unexpected maintenance operations. Indeed, there is a critical need for accurate forecasting methods to predict the demand of these spare parts in order to minimize the so-called Aircraft-On-Ground situations. This paper describes the real-world implementation of the Bootstrap method and the assessment of its performance with actual data from aviation logistics. The analysis reveals that the Bootstrap method, while not the most accurate in every case, should be preferred over other popular methods in spare parts forecasting for aviation, because is more agile and can address adequately all categories of demand. A simple decision support system is then presented to assist airline materials managers in using the bootstrap method. The system is expandable and can potentially incorporate other forecasting method as wel

INVENTORY CONTROL MODELS FOR SPARE PARTS IN AVIATION LOGISTICS

Effective inventory management has a direct influence on monetary savings, high customer service level and product quality and thus plays an essential role in a company's economic and strategic performance. Forecasting and inventory models for aviation logistics are essential in commercial aviation. The objective of this paper is to study the problem of identifying the optimal order quantity of aircraft spare parts and the demand periods using the Order-Up-To (OUT) inventory model in conjunction with the Negative Binomial Distribution (NBD) and the (s, S) inventory model with Revised Power Approximation Method. These models are compared and contrasted via a real-world paradigm. The analysis reveals that the OUT inventory model in conjunction with the Poisson distribution allows ordering the lowest order quantity. However, the (s, S) inventory model with the Revised Power Approximation outperforms it in terms of average total inventory costs

Investigating the female role in the wine sector. Business administration perspective on a Decade of Research (2010–2019)

Wine is one of the most traditional products and bears a high symbolic value, and for some countries of the world, it is the bearer of the knowledge of the community, which contains tangible and intangible assets. It also generates income, employment, economic and social value. Starting from the results of a previous study by the authors (Paoloni et al., Knowl Ecosyst Growth 1132–1156, 2019), this work aims to fill the gaps that have emerged in the literature on the subject of female entrepreneurship in the wine business scenario. To comply with the objective of the document, a bibliographic search was conducted on Scopus, using a series of selected keywords. The literature identified was then analysed using a structured literature review (SRL) proposed by Paoloni and Demartini (Palgrave Commun 2(1):16094, 2016). This paper helps to extend international literature by building a global framework on female entrepreneurship in the wine sector which, starting from the state of the art, highlights the contribution of the female role in the sector, as it provides different inputs for future research and analysis. The main implication of the paper is to advance knowledge and practice on the role of women in the economy and on the contribution of female entrepreneurs to the growth of the country, focusing on empirical researches, theoretical developments, practice and current issues. Taking into account that female entrepreneurship is considered central to the development of economies, the deepening of knowledge on how female entrepreneurs manage relationships – both internally and externally – in their business can help improve policies aimed at promoting the participation of women entrepreneurs in the economy
