Big Data in operations and supply chain management: a systematic literature review and future research agenda
2021
In the era of digitalisation, the role of Big Data is proliferating, receiving considerable attention in all sectors and domains. The domain of operations and supply chain management (OSCM) is no different since it offers multiple opportunities to generate a large magnitude of data in real-time. Such extensive opportunities for data generation have attracted academics and practitioners alike who are eager to tap different elements of Big Data application in OSCM. Despite the richness of prior studies, there is limited research that extensively reviews the extant findings to present an overview of the different facets of this area. The current study addresses this gap by conducting a systema…
Technologia Blockchain i jej zastosowanie w zarządzaniu łańcuchem dostaw
2019
Blockchain is a new technology that allows for decentralized data storage and data verification. Recently, this technology has been gaining more and more interest from representatives of various industries, including logistics and supply chain management. There are more and more voices that Blockchain technology will revolutionize existing business models. However, current research in this area are limited, especially in the logistics and supply chain. Therefore, the aim of this study is the identification of the Blockchain Technology benefits and presenting the potential areas of its application in the supply chain.
Mobile Telephony in Sub-Saharan Africa
2007
A mobile telephone is a telecommunications device that connects its user to a network using a wireless radio wave transmission technology. In some parts of the world, mobile phones are known as cellular phones. Mobile telephones were first introduced in the mid-1980s (Marcussen, 2002; Sadeh & Sadeh, 2002; Sarker & Wells, 2003). Mobile telephony is diffusing globally due to a variety of reasons, including cost advantages in setting up the system compared to landlines, its small-sized nature, portability, and its ability to foster and enhance social relationships, among others (Plant, n.d.; Marcussen, 2002; Sadeh & Sadeh, 2002; Sarker & Wells, 2003; ITU, 2004; Anonymous, 2006)…
Performance and Organisation of Very Small Firms in the Supply Chain
1993
The authors present some results of an empirical research aimed at investigating the evolution of the relationship between large purchasing firms operating on the international market and very small subcontractor firms. The factors that have proved critical in establishing the process of subcontracting are identified and analysed. Under pressure from the high level of international competition, purchasing firms are beginning to demand better qualified and better skilled subcontractors. For many very small firms it effectively means that they are excluded from the large firms’ production cycle or are relegated to a lower position in the supply chain. There are three possible evolutionary pat…
Supply chain modelling and analysis: an application of Latin square to a repeated coupling of non-linear differential equations
2011
In the last 50 years, Forrester’s system dynamics techniques have been adopted to analyse problems and find solutions for global supply chains. An important topic in production-inventory system modelling is the design of experiment. The aim of this paper is to present an application of a statistical technique of design of experiment, the Latin Square Design, to set a combination of input values for the initial-value problem of non-linear repeated coupling of first-order differential equations modelling a production-inventory system. This design permits to reduce the number of experiments while allowing statistical analysis for testing the significance of the studied parameters.
The Challenges Underlying Firm Revival and Resilience in the Post-COVID-19 Phase
2022
Covid-19 is an exogenous shock that has deeply modified the basic building blocks and the micro-mechanisms on which socio-economic systems and organizations rest. The vast majority of both factor markets and final markets have been significantly disrupted on a worldwide scale. As all factors that determine severe crises, the Covid-19 pandemic is a low probability and high impact shock which has significantly changed the environment in which firms operate (Grewal and Tansuhaj 2001, Hudecheck et al. 2020). Such changes have nonetheless been asymmetric, whilst they have menaced the survival of a huge number of firms and have brought to their knees many key industries, it has also ignited rapid…
From the LCA of food products to the environmental assessment of protected crops districts: A case-study in the south of Italy
2010
In the present study, Life Cycle Assessment (LCA) methodology was applied to evaluate the energy consumption and environmental burdens associated with the production of protected crops in an agricultural district in the Mediterranean region. In this study, LCA was used as a ‘support tool’, to address local policies for sustainable production and consumption patterns, and to create a ‘knowledge base’ for environmental assessment of an extended agricultural production area. The proposed approach combines organisation-specific tools, such as Environmental Management Systems and Environmental Product Declarations, with the environmental management of the district. Questionnaires were distribute…
Blockchain for power systems:Current trends and future applications
2020
Abstract Today, the blockchain is synonymous of technological innovation, being recognized among the 10 top strategy technologies in 2018 by the consulting company Gartner, it is more and more adopted in different sectors. However, the initial enthusiasm around this technology is going beyond the peak of inflated expectations, towards more stable applications in money transactions, cryptocurrencies and Digital Commodity Exchanges. Essentially, misguided efforts, the overuse of blockchain, and the Bitcoin's price drop have been the main reasons for this decay in expectations. Nevertheless, the exploitation of the blockchain technology in the power systems area appears largely underexplored, …
A synthesis regarding the application of Expert Systems in Inventory management
2015
The paper surveys the application of Expert Systems in Inventory field in order to find out the relevant aspects needed to build an improved system. The result is a hybrid Expert System-Decision Support System that helps managers to face the uncertainty, complexity and the dynamics of the Inventory Management as the Heart of the Supply Chain Management.
An optimized system dynamics approach for a hotel chain management
2009
The proposed model consists of an integrated system dynamics-data envelopment analysis approach to value, in a dynamic framework, the effects over time of the policies implemented according to the relative efficiency analysis. Rooms’ price and competing facilities (the hedonics) are the decision variables to move in order to push the hotels towards a higher relative efficiency at the end of the observation periods. In fact, in competitive markets as tourism, hotels compete for money offering differentiated quality. Moreover, according to the microeconomic theory, a producer of differentiated goods is not a price taker but a price maker. Therefore, we assume that the decision maker of the ho…
