【摘要】：本文討論了傳統(tǒng)集卡調(diào)度方式的優(yōu)缺點(diǎn)，分析NS港現(xiàn)行的幾套智能化的集卡調(diào)度方式的先進(jìn)性與局限性，提出能將集卡行駛距離和任務(wù)重要程度兩方面因素綜合考慮的基于GPS技術(shù)和模糊控制理論的智能調(diào)度方式。 接著提出了集卡調(diào)度模糊控制系統(tǒng)的總體方案，并詳細(xì)闡述了系統(tǒng)的總體設(shè)計(jì)、算法、模糊化和清晰化過程。隸屬函數(shù)和模糊規(guī)則庫的確定采用專家經(jīng)驗(yàn)法，對碼頭有豐富調(diào)度經(jīng)驗(yàn)的人員發(fā)放調(diào)查表，讓其填寫關(guān)于每一個(gè)論域值對于每一個(gè)模糊集合的符合程度的語言描述，綜合所有接受詢問的人員的意見得到隸屬度函數(shù)的離散點(diǎn)，進(jìn)而得到近似的隸屬度函數(shù)。然后在Matlab中建立此模糊控制系統(tǒng)，計(jì)算出每一對輸入對應(yīng)的清晰化輸出值，得出調(diào)度方案的決策查詢表。實(shí)際工作中，在碼頭管理系統(tǒng)中直接查詢這張表就能為集卡分派最優(yōu)的集卡調(diào)度方案。 最后用Arena建立了傳統(tǒng)調(diào)度方式和模糊控制調(diào)度方式兩個(gè)模型，并從集卡資源飽和、集卡資源不飽和兩個(gè)角度進(jìn)行了詳細(xì)的對比分析。發(fā)現(xiàn)當(dāng)集卡資源過飽和時(shí)，兩種調(diào)度方式的作業(yè)效率相差不大，但對于達(dá)到同樣作業(yè)效率的所需集卡數(shù)量方面，模糊控制調(diào)度系統(tǒng)可以比傳統(tǒng)調(diào)度方式少使用15%左右的集卡資源；當(dāng)集卡資源不飽和時(shí)，模糊控制調(diào)度系統(tǒng)可以提高10%~30%的作業(yè)效率。此結(jié)論證明了模糊控制調(diào)度系統(tǒng)的確能有效的提高集裝箱碼頭的裝卸效率，提高集卡的滿載率，降低集卡投入數(shù)量，，降低集卡單箱能耗。
[Abstract]:This paper discusses the advantages and disadvantages of the traditional card gathering scheduling mode, and analyzes the advantages and limitations of several sets of intelligent card collection scheduling methods in NS Port. An intelligent scheduling method based on GPS technology and fuzzy control theory is proposed, which can consider both the driving distance of the card and the importance of the task. Then, the overall scheme of the card scheduling fuzzy control system is proposed, and the overall design, algorithm, fuzzification and clarity process of the system are described in detail. Membership function and fuzzy rule base are determined by expert experience method. Questionnaire is issued to people with rich dispatching experience in wharf to fill out a linguistic description of the consistency of each domain value to each fuzzy set. The discrete points of membership function are obtained by synthesizing the opinions of all the people questioned, and the approximate membership degree function is obtained. Then the fuzzy control system is established in Matlab, and the corresponding clear output values of each pair of inputs are calculated, and the decision query table of the scheduling scheme is obtained. In practice, by directly querying the table in the wharf management system, the optimal card scheduling scheme can be assigned for the card collection. Finally, two models of traditional scheduling mode and fuzzy control scheduling mode are established by using Arena, and compared and analyzed in detail from two angles of card resource saturation and card resource unsaturated. It is found that when the card resource is supersaturated, the efficiency of the two scheduling modes is not different, but for the number of cards needed to achieve the same job efficiency, The fuzzy control scheduling system can use about 15% less card resource than the traditional scheduling method, and when the card resource is not saturated, the fuzzy control scheduling system can improve the efficiency of 10% or 30%. The conclusion proves that the fuzzy control dispatching system can effectively improve the loading and unloading efficiency of container terminal, increase the full load rate of the container, reduce the input quantity of the card, and reduce the energy consumption of the single container.
