Global Value Chain Governance in the MNE: A Dynamic Hierarchy Perspective

The pandemic crisis caused a severe shock to global value chains and led to supply shortages for complex medical goods such as respiratory ventilators. What followed were calls to reshore production for security, and the loss of efficiencies from foreign global value chain (GVC) operations for the multinational enterprise. This article merges internalization and GVC theory to demonstrate a dynamic hierarchy managerial response to these crisis conditions. An optimally configured GVC under hierarchy governance can resiliently eliminate global supply line ruptures yet maintain the benefits of global efficiency.

Determining the Electrical Losses in the Electrical Supply Line of a Sprinkler Using Autonomous Asynchronous Generator

The use of an asynchronous generator to power the electrical equipment of the sprinkler is a comprehensive solution that allows you to reduce electrical losses in the supply line. The problem of reactive power compensation for sprinkler machines can be solved by dividing capacitor units into main and additional, the main one is to create the required excitation current in the asynchronous generator, and the additional one is to compensate for the reactive component of the electric motor current. Moreover, an additional unit is installed directly at the outputs of the booster pump to unload the line, and the main capacitor unit is installed near the asynchronous generator.

RELATED REGULATION OF BIOGAS SUPPLIES AND METHANE IN A GAS ENGINE

The results of experimental researches were received on a gas-electric installation with a rated power of 30 kW at 1500 rpm. The spark-ignited petrol drive engine (8-cylinder, 100 mm cylinder diameter, 88 mm stroke) was converted to a pure gas one. The compression ratio of 8.5 did not change. The gas fuel supply system consists of a supply line and an emergency shut-off circuit. The natural gas supply line was connected to the domestic main line through a special gas distributor. On the basis of HEINZMANN components, a system for dosing mixed gas fuel was developed, which, through a microprocessor control unit and an actuator, acted on the throttle valve of the gas mixer. In experimental researches, the composite fuel was a model gas – a mixture of natural and carbon dioxide gases, which was prepared in a zero pressure reducer before the gas mixer. With an increase in the volume fraction of carbon dioxide in the model gas by more than 34 %, a deterioration of the combustion process was observed in the steady state. In the article, based on the analysis of the experimental results of the operation of a piston gas engine on a model gas, an algorithm for the use of associated automatic control of biogas and methane feeds is substantiated. The transition from quantitative to qualitative regulation of the gas-air mixture has been substantiated. To do this, it is necessary to create two automatic control loops for the supply of air and a mixture of natural gas, which are interconnected through an external load. With the developed algorithm, as the load increases, the supply of natural gas increases, and the supply of biogas decreases. With an increase in the load of 75 % or more, a more intensive enrichment of the fuel mixture with natural gas occurs than at low and medium loads. The proposed algorithm for regulating the fuel mixture can be implemented using electromagnetic gas injectors for dosing the components of the composite fuel. Signals from sensors for oxygen and methane content in exhaust gases were selected as corrective links for the coupled control algorithm. Recommendations on the choice of tuning modes for oxygen and methane sensors have been developed.

EFFICIENCY MODEL FOR THE PROLIFERATION OF SECONDARY MARKET SUPPLY CHAIN – WITH REFERENCE TO THE INDIAN GARMENT CLUSTER

The growth of secondary market in retail garment trade has been a major boost to economic growth in developing nations. This paper highlights the importance of effective forward and reverse supply chain the garment sector as driver for this booming secondary market. A conclusive research technique has been adapted to study the supply chain practices followed in the garment business those in the primary and secondary market. Structural equation modelling is used to validate and test the proposed model for supply chain performance. Cluster sampling method was incorporated. Owners of garment manufacturing firms in and around Coimbatore, Tirupur, Salem, Bargur and Bengaluru region would form the respondent group. A structured questionnaire was given to them to understand their supply chain practices, supply chain flow velocity and flow efficiency and its impact on their business performance. The firms operating under uncertain circumstances in the secondary supply line have adopted practices which lead to appropriate velocity and efficient flow of money, material and information which has been proved through the testing of the model. The velocity and efficiency in the supply line has improved the performance thereby ensuring a more sustainable business for the firm operating in the secondary markets. This study has contributed in understanding the various dimensions of best supply chain practices and its effect on the flow velocity and flow efficiency of the money, material, and information in the secondary market garment supply chain. An assessment of the results of the study has opened a window to the operations of the secondary garment supply chain line in the Indian cloth market which have been more or less camouflaged under the primary market operations. The outcome of the research also shows that these secondary market players have evolved their own strategies to sustain in volatile and uncertain circumstances. These strategies have proved to be very effective in minimizing wastage and increasing profitability of the manufacturing firms. The implications of this study is bound to give much needed support and leverage to the frail and underperforming secondary garment cluster which is a major contributor of Gross Domestic Product and employment ratio.
