Firstly, a 0 - 1 integer programming mathematical model is constructed to describe tail - number - assigning work happened in domestic airline, since the problem is npc, a unified polynomial algorithm which satisfies engineering requirement is unavailable. illuminated by the practical experience, a specific tna problem is classified into one of three typical tna modes : tna based on fleet dispatching commands, tna based on fleet balance application, tna based on minimum fleet requirement ; secondly, by simplifying and relaxing some minor constraints, corresponding mathematical models and heuristic algorithms are reconstructed for each typical tna mode ; finally, computing complexities are discussed
為此論文在借鑒手工編制排班計劃經驗的基礎上，將一個具體的飛機排班問題，歸結為三種典型排班模式中的一種，即：基於飛機調度指令要求的排班問題，基於飛機使用均衡要求的排班問題和基於最少需用飛機數的排班問題，對于每種典型的飛機排班模式，在對次要的約束條件進行簡化、松馳的基礎上構造出相應的能夠滿足工程應用要求的啟發式演算法，並分析了演算法的復雜性。The rayleigh - ritz method is used to lead to analytical expressions for the stiffness and mass matrices and load vector as well as their sensitivities, which uses the simple polynomials to define assumed displacement functions, geometry and construction of wing structures. excluding some selected terms from the displacement functions or using stiff springs at the specified locations imposes boundary conditions. the accuracy of calculated results is improved by including transverse shear effects and using multiple sets of ritz functions in the analysis
它使用簡單多項式作為ritz基函數、定義翼面的幾何和結構參數，利用rayleigh - ritz方法導出翼面結構的剛度矩陣、質量矩陣和載荷向量及其靈敏度的解析表達式，通過排除位移函數中某些選定的項或在指定點使用約束彈簧施加各種邊界條件，考慮橫向剪切變形和使用多組ritz基函數改進分析的質量，使用等效蒙皮和等效夾芯技術提高計算效率。
