By defining the path flow ratio to establish the probabilistic space of the path entropy, the calculating model of path entropy is developed. And the sequential method and the separate-layer ranking thought are used to solve the model.
Computation result shows that the flow assignment of the algorithm is identical to Logit-based path flows and Dial's algorithm data,the algorithm directly computes link flow and turn flow patterns,which not only agrees with Logit route-choice probability,but also counts for the effect of turn delays on traffic assignment,and Dial algorithm is a special case of the algorithm when all turn delays vanish. 5 tabs,3 figs,10 refs.
Secondly,because the logit model applied to the traffic assignment is only suit to the problem of the trip cost independent of the number of passengers on the route and the stochastic user equilibrium model is abstruse and complex in solution,the author brought forward the ameliorative method of the logit model.
The optimized assignment of the manufacture routes of work-pieces in FMS is the crucial issue following the system planning and design, as well as the manufacture management and scheduling. In this issue, the characteristics of NP-complete make the most optimized solutions inaccessible via multinomial.
(5) Combined with a concrete example of FMS, the computerized result of Ant-cycle system is provided and compared with simulated annealing algorithm. And the final conclusion is drawn that ACO is a perfect to solve the problem of the optimized assignment of the manufacture routes of work-pieces in FMS.
Secondly, introduces a flexible manufacturing system machining optimization flow path optimization theory and the distribution of the NP-complete problems faced. In comparison to address such issues as the use of several heuristic search algorithm and tabu-insert search algorithm based on simulated annealing algorithm highlights the advantages and disadvantages of the Ant Colony Optimization and Genetic algorithm.
Movable Electrical Conducting Probe (MECP), a kind of simple and reliable measuring transducer, used for predicting full-flow-path flow pattern in a boiling vapor/liquid two-phase flow is introduced in this paper.
Among these three approaches, the segmented path flow-based approach presents the highest robustness to the system stochasticities/randomness, but at the cost of restricted vehicle routings and the need for complicated handling operations.
The process alternatives for new process design as well as retrofit design are generated through a systematic method that is simple yet effective and is based on a recently developed path flow analysis approach.
In addition, this connection provides us with a novel interpretation of the financial network equilibrium conditions in terms of paths and path flows and a direct existence result.
In this paper we propose a new iterative method for solving the asymmetric traffic equilibrium problem when formulated as a variational inequality whose variables are the path flows.
