【摘要】：計劃、調度和控制是項目管理實踐的核心內容。在現(xiàn)代造船模式中，由于船體分段相互之間依賴強、數(shù)量多，而且建造過程中占用場地、機械等資源，低效率高成本的項目管理難題普遍存在。因此，分段調度計劃決定了分段項目建造的周期及資源配置的效率。人工編制的調度計劃，存在著計劃更新緩慢、項目建造周期長、資源利用效率低等諸多問題，不利于提高造船企業(yè)經(jīng)濟效益。通過對船體分段調度計劃過程進行研究，有利于縮短船體分段建造周期，，對提高造船企業(yè)制造效率意義重大。 本文對船體分段調度計劃問題進行了探討。首先對船體分段建造過程中的資源種類進行分析，界定常規(guī)線性資源與場地資源的約束條件與使用規(guī)則，將常規(guī)線性資源與場地資源結合為混合資源。然后建立混合資源約束下的項目調度評價指標，考慮船體建造過程中的實際情況，提出混合資源優(yōu)化調度假設，建立混合資源優(yōu)化調度模型，并運用啟發(fā)式算法對模型進行求解。最后，以造船企業(yè)為樣本，以混合資源優(yōu)化調度方法為基礎，設計實現(xiàn)了混合資源項目計劃優(yōu)化調度工具，實現(xiàn)調度結果的輸出與可視化顯示。 通過對比企業(yè)調度數(shù)據(jù)與優(yōu)化后的調度結果得出，面向船舶制造混合資源的項目計劃優(yōu)化調度模型能夠較好反應船體分段項目的調度過程，求解方法能夠縮短船體分段建造周期。
[Abstract]:Planning, scheduling and control is the core content of project management practice. In modern shipbuilding mode, because the mutual dependence between hull, number, and occupation in the process of the construction site, machinery and other resources, common project management problem of high cost and low efficiency. Therefore, subsection scheduling scheme determines the project construction cycle segment and the efficiency of resource allocation. The artificial scheduling plan, there are plans to update the slow, long project construction period, many problems of resource utilization efficiency is low, is not conducive to improving the economic benefit of shipbuilding enterprises. Through the research of block scheduling plan for ship hull process, shorten the construction cycle, to improve the manufacturing efficiency of shipbuilding enterprises great significance.
This paper discusses the problem of scheduling on the hull. The first section of the hull construction process resources analysis, constraint definition of conventional linear resources and space resources and the use of rules, the conventional linear combination of resources and space resources for mixed resources. To establish evaluation index of hybrid scheduling resource constrained project and the actual. Considering the hull construction process, this paper proposes hybrid scheduling assumptions, the establishment of mixed resource optimization scheduling model and a heuristic algorithm is used to solve the model. Finally, the shipbuilding enterprises as samples, with optimization method of mixed resource scheduling based on the design and implementation of hybrid resource project plan optimization scheduling tool, display and visualization the scheduling results.
By comparing the scheduling data and optimized scheduling results, it is concluded that the scheduling optimization model for ship manufacturing hybrid resources can better respond to the scheduling process of hull section projects, and the solution method can shorten the hull construction period.
