BACKGROUND The production of fuel-grade ethanol from lignocellulosic biomass resources has the potential to increase biofuel production capacity whilst minimising the negative environmental impacts. These benefits will only be realised if lignocellulosic ethanol production can compete on price with conventional fossil fuels and if it can be produced commercially at scale. This paper focuses on ...

In this paper, using the maximum principle for analyzing dynamic cost, we propose a new twostage supply chain model of the manufacturing-assembly mode for high-tech perishable products supply chain and obtain the optimal conditions and results. On this basis, we further research the effect of localization of CODP on the total cost and the relation of CODP, inventory policy and demand type throu...

In modern conditions, a number of factors affect the activities enterprises, which include tough competitive environment, limited material resources, and economic crisis caused by COVID-19 pandemic. To improve its efficiency, it is necessary to minimize costs manufacturing products, performing work providing services. Effective rational internal control contributes solution this task. regard, i...

Intense international competition pushes the actors of wood supply chains to implement efficient chain management incorporating coordinated cost-saving strategies remain competitive. In order observe effects individual and decision making, mixed-integer programming models for forestry, round-wood transport, wood-based industry were developed integrated. The deal with operational planning issues...
