The author presents a methodology which is used first to model a product-manufacturing-and-distribution system, and then to predict the resulting changes in environmental impact from changes either in taxation or in costs of inputs. A case study of the paper sector in the eastern and central United States is developed, derived from the 1993 US Commodity Flow Survey. From an analysis of five scenarios, two central findings arise: (1) the model is found to be unresponsive to even large changes in transport taxation, so an environmental policy which considers both transportation and production aspects at the same time is favored, and (2) fluctuations in raw-material costs can have an influence on environmental impact as great as or greater than that of changes in taxation levels.

Performance a nalysis of an organization has a major role in setting t he strategy followed especially during the financial crisis. In what follows we performed a financial analysis, based on data from the balance sheet and profit and loss account of a company that produces and sells crystal sugar, using a system of indicators that are relevant. Using the results of this economic analysis we can draw certain conclusions according to which can forecast future developments. I tried to use a number of indicators of a system that defines, in the end, a model for analyzing the economic performance of a compa ny. The research focused on the application of the diagnostic performance of agreed financial data recorded by that company.

Purpose – The purpose of this paper is to explore the specific practices of management in the dispatching unit and to identify mechanisms for supporting transfer of shop floor knowledge embedded in operating manufacturing equipment. Design/methodology/approach – The paper applies an inductive and a case study approach for exploring three empirical cases that represent different manufacturing facility relocation processes and differences in the applied managerial practices. Findings – The paper identifies two important gaps in international production literature when firms relocate equipment to other sites; a time gap (from dismantling to re-assembly of production facilities) and a space gap (from the current to the new site abroad). These gaps are important for understanding why relocation processes are difficult and what management can do to facilitate such processes. Practical implications – The paper identifies four issues that management faces in the dispatching context when relocating manufacturing facilities. Originality/value – The paper gives new insights to a limited literature of shop floor knowledge transfer when relocating manufacturing facilities.

The Industrial Internet of Things (IIoT) is known to be a complex system because of its severe constraints as it controls critical applications. It is difficult to manage such networks and keep control of all the variables impacting their operation during their whole lifecycle. Meanwhile, Digital Twinning technology has been increasingly used to optimize the performances of industrial systems and has been ranked as one of the top ten most promising technological trends in the next decade. Many Digital Twins of industrial systems exist nowadays but only few are destined to networks. In this paper, we propose a holistic digital twinning architecture for the IIoT where the network is integrated along with the other industrial components of the system. To do so, the concept of Network Digital Twin is introduced. The main motivation is to permit a closed-loop network management across the whole network lifecycle, from the design to the service phase. Our architecture leverages the Software Defined Networking (SDN) paradigm as an expression of network softwarization. Mainly, the SDN controller allows for setting up the connection between each Digital Twin of the industrial system and its physical counterpart. We validate the feasibility of the proposed architecture in the process of choosing the most suitable communication mechanism that satisfies the real-time requirements of a Flexible Production System.
