Quo vadis, logistica?
This abstract answers the following questions: "Is it necessary to do things differentia telly?", "Do new strategies express new technologies as well?", Are the cost savings still important?, "Which effects can be achieved by logistic solutions?", Things are necessary to where they can be done better?", "Which are limits of that?", "How does the development effects the logistic market?", "Could firms choose the right logistic partners?".
Innovation in Logistics: The Impact on Transport and the Environment
Publisher Summary This chapter examines the innovations in logistics and their impact on transport and the environment. It emphasizes on three important innovations: (1) centralization of inventory, (2) 24-hour lorry operations, and (3) just-in time delivery. It also describes companies' motivations in relation to logistics and the consequences for transport. It also explores the policy initiatives that might succeed in reducing the environmental impact of road-freight transport. One of the classic relationships in logistics is the tradeoff between warehousing-arid transports. As the number of warehouses increases, the cost of operating them also increases, but transport operating cost falls, for a constant throughput of goods through the warehouse. Companies carrying high-value inventory, have been keen to convert to a system of distribution based on a central warehouse, rather than maintaining a network of, say, 10 regional warehouses. The consequences for transport of centralizing inventory have been calculated using P–E International's TRANSPLAN distribution software package.
Mathematical Simulation of Combustion of Boron Powder Gas Suspension
Based on a two-phase two-velocity model of a reacting gas-dispersed medium, a mathematical model of combustion of a boron powder gas suspension has been formulated. The results of numerical solution of the problem are presented. The influence of the composition of the gas suspension, its size, size distribution of particles, mass concentration of particles, as well as of the presence of aluminum powder in the suspension on the visible and normal velocities of flame propagation in the gas suspension, is shown. A comparison of the results of calculation with the well-known experimental and theoretical data is carried out. Satisfactory agreement of the predicted results with experimental data is shown.
