With the blending ratio calculated from production scheduling , a mixed integer programming model of oil storage and transfer scheduling is proposed based on the oil inventory and output planning , the problem of oil storage both in the port tank and in the refinery tank are solved , the results can be used for the oil management 根据炼油生产调度得到的油品调合比例,结合产品库存和出厂计划,对成品油的调合问题进行了描述。并分别以厂内罐区和码头罐区为对象,提出了成品油储运调度的混合整数规划模型,从而解决了成品油调合、存储和移动等一系列问题,为成品油罐区的管理提供了技术支持。
However , signals take effect by the switch of signal phases , which introduces integer control values into the traffic control problem , so the traffic control problem becomes a large - scale mixed integer programming problem , the computation of which requires an exponential - complexity optimiz ation algorithm 但是,信号灯通过相位切换对交叉口进行控制,同时也在交通控制模型中引入了整数决策变量,使交通控制模型成为一个大规模混合整数规划问题,需要指数复杂度的优化算法。
Jon edvardsson et al pointed out that the technique developed by neelam gllpta et al is neither complete nor terminationai for w on which all of the predicate functions with respect to the input variables are linear , and suggested using linear programming and linear ( mixed ) integer programming methods instead Jonedvardsson等人指出,对于谓词函数均为输入变量的线性函数的程序路径, neelamgupta等人提出的求解方法是不完备的和非终止的,并建议采用线性规划、线性(混合)整数规划方法。
A path - wise test data generation framework is proposed in this thesis , whose fundamental algorithm is the improved method . this framework adopts a constraint solver using linear programming and linear ( mixed ) integer programming methods for w on which all of the predicate functions with respect to the input variables are linear . for w on which there is nonlinear function ( s ) with respect to the input variables 该框架以改进后的迭代松弛法为核心算法,对于谓词函数均为输入变量的线性函数的程序路径,采用基于线性规划、线性(混合)整数规划的约束求解器;对于谓词函数中含有输入变量的非线性函数的程序路径,采用线性规划、线性(混合)整数规划和最小二乘解法相结合的约束求解器。
The elip is suitable for the case that the uncontrollable subnet is cascade petri net and some cascade subnets are neither acyclic petri nets nor state graphs , and the main character is that the nonlinear integer program problem is converted into the problem that can be solved by using some standardized mathematical tools 当不可控子网是序状petri网,且无法用整数规划法综合控制器时,可使用扩展线性整数规划法,该方法的优点在于把非线性整数规划转化为可用标准数学工具求解的问题。
One is single node dba mixed integer programming ( sdmip ) , the other is double node dba mixed integer programming ( ddmip ) . the result of dba model is used as a restraint in the reconfiguration model , which is one of the strong points of this paper . the purpose of this paper is to support the action of selecting address and allocate resource more efficiently 并把dea评价的结果作为一项约束代入到选址模型中,经过这样处理的模型具有特殊的优点,能够把顾客的服务满意度在模型中予以体现,同时还能够使资源在各配送中心之间重新分配,使资源的利用率得以提高。
An integer programming problem is a mathematical optimization or feasibility program in which some or all of the variables are restricted to be integers. In many settings the term refers to integer linear programming (ILP).
