Research On The Optimization Distribute Of The Fund In Books Purchasing

Modern libraries pay more attention on the using of document and the content of the readers' information need . Only by being used can the value of collect books be carried out. But now the estimate of optimal library benefit mostly rests on the qualitative point of view. It was short of normative scalar target.According to this circumstances , the article inducts the parameter of circulation benefit based on the rule of library being used and readers' satisfied rate on the point of economic view, combines every factors in order to find a rational outlay distribution and make the limited fund to exert the most economy benefit with the tool of operational research.First we need to define the goal of a library, fix the aim to achieve . Also ,we confirm the priority gene of every kind of books with Analytic Hierarchy process(AHP).Second the article points out that the law of diminishing marginal utility is the same with the distributing of the fund in books purchasing . The fact in circulation and the value of books' are synthetically considered , then the parameter of circulation benefit is put forward which is used to judge the utility of collect books in use.The highest total utility can be ensured when the fund is distributed according to the equal marginal utility . Thus, the optimization distribute of fund have proper economics sense.After finishing the analysis of correlation parameter, we construct the model of fund distributing, and seek the satisfying solve of the problem with Nonlinear programming.
