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 根據煉油生產調度得到的油品調合比例,結合產品庫存和出廠計劃,對成品油的調合問題進行了描述。并分別以廠內罐區和碼頭罐區為對象,提出了成品油儲運調度的混合整數規劃模型,從而解決了成品油調合、存儲和移動等一系列問題,為成品油罐區的管理提供了技術支持。
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,信號燈通過相位切換對交叉口進行控制,同時也在交通控制模型中引入了整數決策變量,使交通控制模型成為一個大規模混合整數規劃問題,需要指數復雜度的優化算法。
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,對于謂詞函數均為輸入變量的線性函數的程序路徑, neelamgupta等人提出的求解方法是不完備的和非終止的,并建議采用線性規劃、線性(混合)整數規劃方法。
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 該框架以改進后的迭代松弛法為核心算法,對于謂詞函數均為輸入變量的線性函數的程序路徑,采用基于線性規劃、線性(混合)整數規劃的約束求解器;對于謂詞函數中含有輸入變量的非線性函數的程序路徑,采用線性規劃、線性(混合)整數規劃和最小二乘解法相結合的約束求解器。
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 當不可控子網是序狀petri網,且無法用整數規劃法綜合控制器時,可使用擴展線性整數規劃法,該方法的優點在于把非線性整數規劃轉化為可用標準數學工具求解的問題。
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評價的結果作為一項約束代入到選址模型中,經過這樣處理的模型具有特殊的優點,能夠把顧客的服務滿意度在模型中予以體現,同時還能夠使資源在各配送中心之間重新分配,使資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).
