【摘要】：起重機是工程建設(shè)中廣泛使用的重要設(shè)備,對保證工程建設(shè)順利進行有著重要作用。近年來,隨著工程機械行業(yè)的發(fā)展,起重機產(chǎn)品型號和品牌不斷增加,如何選擇最合適的起重機成為廣大用戶關(guān)心的問題。要做出正確的決策首先要對起重機產(chǎn)品進行客觀的評價,對起重機的評價往往針對其綜合性能,而起重機的性能體現(xiàn)在多個方面,考慮的指標較多,評價具有一定的復雜性。因此,研究起重機指標體系及評價方法,利用科學的評價方法得到客觀、合理的評價結(jié)果,具有重要的現(xiàn)實意義。 本文在了解各類起重機的性能參數(shù)的基礎(chǔ)上,針對起重機綜合評價的特點,從指標體系的建立、指標權(quán)重的確定、評價模型的應用等環(huán)節(jié)出發(fā),展開了系統(tǒng)的研究,探索適合起重機產(chǎn)品評價的綜合評價方法,并開發(fā)起重機綜合評價系統(tǒng),將起重機的綜合評價方法利用軟件的方式實現(xiàn)和應用。 在現(xiàn)有工程機械方面產(chǎn)品評價指標體系的基礎(chǔ)上,根據(jù)起重機評價指標的特點,結(jié)合指標篩選的理論方法,提出定量分析方法,分析指標之間的相關(guān)性和指標的區(qū)分能力,并結(jié)合定性分析,得到分層的指標體系。然后將指標體系的構(gòu)建方法應用到汽車起重機綜合評價指標體系的建立中。 分析現(xiàn)有的權(quán)重確定方法,為解決熵權(quán)法在應用中存在的問題,提出改進的熵權(quán)法,并通過分析和實例應用證明改進方法的合理性。利用向量貼近度代替Spearman秩相關(guān)系數(shù)來反映不同賦權(quán)方法所得結(jié)果之間的一致性程度,并考慮到?jīng)Q策者的偏好,研究基于決策者偏好和賦權(quán)結(jié)果一致性的組合賦權(quán)法。 分析在TOPSIS法綜合評價中“垂面”距離相對于歐式距離的優(yōu)點,將組合賦權(quán)法應用在改進TOPSIS法綜合評價的權(quán)重確定中,應用評價實例驗證改進TOPSIS法綜合評價模型的合理性和實用性。 開發(fā)起重機綜合評價系統(tǒng),將本文的綜合評價方法集成到系統(tǒng)中,通過應用實例證明了評價結(jié)果的合理性和系統(tǒng)的實用性。
[Abstract]:Crane is an important equipment widely used in engineering construction, which plays an important role in ensuring the smooth progress of engineering construction.In recent years, with the development of construction machinery industry, crane product models and brands continue to increase, how to choose the most suitable crane has become a problem of concern to the majority of users.In order to make correct decision, it is necessary to evaluate the crane product objectively. The evaluation of crane is usually based on its comprehensive performance, but the crane performance is reflected in many aspects, and the evaluation has some complexity.Therefore, it is of great practical significance to study the index system and evaluation method of crane, and to obtain objective and reasonable evaluation results by using scientific evaluation method.On the basis of knowing the performance parameters of all kinds of cranes, this paper starts with the establishment of index system, the determination of index weight, the application of evaluation model and so on, aiming at the characteristics of comprehensive evaluation of cranes.This paper explores a comprehensive evaluation method suitable for crane product evaluation and develops a crane comprehensive evaluation system. The comprehensive evaluation method of crane is realized and applied by software.On the basis of the existing evaluation index system of construction machinery products, according to the characteristics of crane evaluation index and combining with the theoretical method of index screening, the quantitative analysis method is put forward, and the correlation between indexes and the ability of distinguishing indexes are analyzed.Combined with qualitative analysis, a hierarchical index system is obtained.Then, the construction method of index system is applied to the establishment of comprehensive evaluation index system of truck crane.In order to solve the problems existing in the application of entropy weight method, an improved entropy weight method is put forward, and the rationality of the improved method is proved by analysis and practical application.Vector closeness degree is used instead of Spearman rank correlation coefficient to reflect the degree of consistency among the results obtained by different weighting methods. Considering the preference of decision makers, a combined weighting method based on the consistency of decision makers' preferences and weighted results is studied.This paper analyzes the advantages of "vertical plane" distance relative to Euclidean distance in TOPSIS comprehensive evaluation, and applies the combined weighting method to determine the weight of improved TOPSIS comprehensive evaluation.The rationality and practicability of the improved TOPSIS comprehensive evaluation model are verified by an evaluation example.The comprehensive evaluation system of crane is developed and the comprehensive evaluation method of this paper is integrated into the system. The rationality of the evaluation results and the practicability of the system are proved by an application example.
