In this work we propose a bi-criterion, multi-period, stochastic mixed-integer linear programming model that address the optimal design and planning of hydrocarbon biorefinery supply chains under supply and demand uncertainties. The model accounts for diverse conversion technologies, feedstock seasonality and fluctuation, geographical diversity, biomass degradation, demand variation, government incentives...
In this paper, it proposes fuzzy neural network(NN) system which is used for management decision-making and composed of three separate networks. The system's input can be both figures and vector language. The system's output exceeds the standard neural network - two-valued logic state. Based on the ambiguity function, NN's back-propagation algorithm and the monotonic function NN model the paper proposes...
This paper presents a Pore Network Model (PNM) based methods for design scaffold. In this modeling process, plenty of unit spheres that distributed in space coordinate randomly with different diameter within limits are created and permeated into the whole scaffold space. When the total volume proportion of the unit spheres ascends to a certain value, a PNM model is formed with the topological structure...
By establishing a novel model on the growth of knowledge stocks, we first perform analysis on the requirements that enterprises join a patent pool. After that, a function model of knowledge absorption capacity is introduced, based on which, we take the influence on absorption capacity into account in view of the investment proportion of knowledge stocks by enterprises in the patent pool. We further...
Because Web service function is continually strengthened, and Web service quantity increases rapidly, it is urgent to solve the problem on automatic service matching and composition to meet service request. The service matching algorithm for bionic manufacturing domain-specific ontology is proposed in the paper. For this algorithm, the semantic similarity between two concepts is calculated according...
An algorithm to generate macro-pores of bionic bone scaffold is proposed based on knapsack problem model in the paper. That is to construct the negative model of macro-pore structure of bionic bone scaffold according to the structure of knapsack problem model, with the ellipsoid as the basic unit, and the three-dimensional boundary of scaffold as the constrained space. Then, the model of bionic bone...
