從投入產出的角度講，如何提高飯店核心競爭能力，以達到提高企業經濟效益，盡快產生回報，加速貨幣回籠的目的，是飯店業嚴肅的話題。在經歷了近二十年步履艱難的國企改革歷程后，我國飯店業已開始由幼稚走向成熟，由賣方市場走向買方市場，這種轉變將使得部分理性的消費者享受到物有所值，也使部分膚淺的飯店品嘗到必然的失敗；近十年來，作為飯店業占相當比重的國有飯店在跨國飯店集團和民營飯店企業的雙重沖擊下，歷經了金融體制改革及銀行商業化、市場開放及解控、市場及競爭機制三個階段，由於計劃經濟遺留下來的問題、結構不合理造成的問題和重復投資造成的問題等三方面的原因，使得國有飯店在市場競爭中逐漸喪失競爭優勢，相繼出現困境，如何提高國有飯店競爭力的問題，對於我國旅遊業具有強烈的現實意義，湖南芙蓉賓館就是一家極具代表性的國有三星級飯店。Recently, color doppler ultrasound has played an adjunctive role in the detection of renal a vm for its non - invasive means and efficiency
近日，都卜勒超音波夾其非侵犯性及高準確度的優勢，在動靜脈畸型的診斷上，扮演重要的角色。Optimized association rules are permitted to contain uninstantiated attributes. the optimization procedure is to determine the instantiations such that some measures of the roles are maximized. this paper tries to maximize interest to find more interesting rules. on the other hand, the approach permits the optimized association rule to contain uninstantiated numeric attributes in both the antecedence and the consequence. a naive algorithm of finding such optimized rules can be got by a straightforward extension of the algorithm for only one numeric attribute. unfortunately, that results in a poor performance. a heuristic algorithm that finds the approximate optimal rules is proposed to improve the performance. the experiments with the synthetic data sets show the advantages of interest over confidence on finding interesting rules with two attributes. the experiments with real data set show the approximate linear scalability and good accuracy of the algorithm
優化關聯規則允許在規則中包含未初始化的屬性.優化過程就是確定對這些屬性進行初始化，使得某些度量最大化.最大化興趣度因子用來發現更加有趣的規則;另一方面，允許優化規則在前提和結果中各包含一個未初始化的數值屬性.對那些處理一個數值屬性的演算法進行直接的擴展，可以得到一個發現這種優化規則的簡單演算法.然而這種方法的性能很差，因此，為了改善性能，提出一種啟發式方法，它發現的是近似最優的規則.在人造數據集上的實驗結果表明，當優化規則包含兩個數值屬性時，優化興趣度因子得到的規則比優化可信度得到的規則更有趣.在真實數據集上的實驗結果表明，該演算法具有近似線性的可擴展性和較好的精度The composites not only show excellent photo - responsive properties in the visible and near - ir region ( 450 ~ 850 nm ), but also show complementary and synergetic enhancement effects in photosensitivity in the visible and near - ir region. the reasons for the enhanced photoconductive properties and new effects are explained in terms of the partial and directional charge transfer from phthalocyanine to azo compound in these azo / tiopc composites. 2
