Concave resource allocation problem is an integer programming problem of minimizing a nonincreasing concave function subject to a convex nondecreasing constraint and bounded integer variables. This class of problems are encountered in optimization models involving economies of scale. In this paper, a new hybrid dynamic programming method was proposed for solving concave resource allocation problems. A convex underestimating function was used to approximate the objective function and the resulting convex subproblem was solved with dynamic programming technique after transforming it into a 0-1 linear knapsack problem. To ensure the convergence, monotonicity and domain cut technique was employed to remove certain integer boxes and partition the revised domain into a union of integer boxes. Computational results were given to show the efficiency of the algorithm. 相似文献

With the rapid development of highway construction and formation of the highway network in China,the man- agement of pavement maintenance and rehabilitation （MR） activities has become important.In this paper,four discrete optimization models are proposed for different parties involved in the management system： government,highway agent,con- tractor and the common users.These four optimal decision models are formulated as linear integer programming problems with binary decision variables.The objective function and constraints are based on the pavement performance and prediction model using the pavement condition index （PCI）.Numerical experiments are carried out with the data from a highway system in Sichuan Province which show the feasibility and effectiveness of the proposed models. 相似文献

In this paper, a new method named as the gradually descent method was proposed to solve the discrete global optimization problem. With the aid of an auxiliary function, this method enables to convert the problem of finding one discrete minimizer of the objective function f to that of finding another at each cycle. The auxiliary function can ensure that a point, except a prescribed point, is not its integer stationary point if the value of objective function at the point is greater than the scalar which is chosen properly. This property leads to a better minimizer of f found more easily by some classical local search methods. The computational results show that this algorithm is quite efficient and reliable for solving nonlinear integer programming problems. 相似文献

互动式教学模式是一种开放性、多向性、启发性的教学模式。互动式教学模式在具体的教学实践过程尚存在一些亟待解决的问题,处理不好,往往事倍功半、收效甚微。针对这些问题,结合《文学理论》教学的实际,笔者提出了优选互动节点、活用互动方式、构建互动平台、营造互动环境等四点策略。以兹为互动式教学模式全面、深入、有效的展开提供借鉴,为我校本科教学工作改革尽绵薄之力。 相似文献

1IntroductionReliability opti mization plays an i mportant role inthe planning and design of moderntechnological syste-ms[1,2].Although components with high reliability canbe manufactured as the modern technology deve-lops,the requirements for the systems reliability are oftenbeyond the capability of manufacturing.This is spe-cially true for systems where a failure of the systemwill result in catastrophic consequence.On the otherhand,adopting high reliability components in a systemmay be infea… 相似文献
