摘要： Aimed at the uncertain characteristics of discrete logistics network design, an interval hierarchical triangular uncertain OD demand model based on interval demand and network flow is presented. Under consideration of the system profit, the uncertain demand of logistics network is measured by interval variables and interval parameters, and an interval planning model of discrete logistics network is established. The risk coefficient and maximum constrained deviation are defined to realize the certain transformation of the model. By integrating interval algorithm and genetic algorithm, an interval hierarchical optimal genetic algorithm is proposed to solve the model. It is shown by a tested example that in the same scenario condition an interval solution [3 275.3, 3 603.7] can be obtained by the model and algorithm which is obviously better than the single precise optimal solution by stochastic or fuzzy algorithm, so it can be reflected that the model and algorithm have more stronger operability and the solution result has superiority to scenario decision. © 2013 Central South University Press and Springer-Verlag Berlin Heidelberg.

关键词： Discipline construction;Service mode;Special library in department

摘要： The special libraries in departments with the comprehensive library of university constitute together a multi-level, multi-faceted and multi-type college literature resources sharing system. The special libraries in department could be play an unique role for discipline construction and join in discipline construction through providing several services including literature and information service, special works service and date processing. In the construction of special library in department, special attention must be paid to the purchase of professional books, the reformation and innovation of service mode to highlight the construction of discipline, and also the enhancing professional qualities of librarians.
