Chinese Abstract

由於世界各地對於工程管理的要求逐漸嚴格,工程專案排程問題漸受重視。然而,隨者台灣企業對外發展的迅速成長,必須在外地大規模的建造廠房,造成專案排程必須考量的問題日趨複雜。過去主要應用計畫評核術與要徑法作為專案排程的技術,但近年來企業在外地發展時,常常碰到人員派遣及人力資源取得不易等問題,只考量工期的控制而未考量有限人力資源配置的問題,將使企業所做出的決策缺乏實際面。因此,考慮有限人力資源的資源配置排程問題逐漸受到企業重視。除了人力資源的配置之外,企業發展面臨到的另一個棘手問題就是資金的流動。過去主要應用要徑法與計畫評核術的研究,以資源無限制的情況進行專案排程,此作法未考量實際作業時所碰到的成本問題,將使原規劃的排程結果失去最佳性。因此,本研究針對有限人力資源配置情況下的作業排程進行成本最小化模式之研究,構建一最佳化之專案排程模式,協助決策者有效地進行規劃。本研究參考管理科學所提到的規劃求解方法建構一試算表模式,並應用最短路徑問題作為排程的方法,達成成本最小化的目標。此模式為一整數限制式的網路最佳化問題,可利用簡單的Excel軟體作求解。 為測試本研究試算表模式求解績效,本研究以一實際企業案例作為研究對象,該企業於2011年時,為了規劃2012年在大陸建廠的人事成本所擬訂出的初步預算表。針對此專案資訊,進行一範例研究,進行個案分析,並將有限資源重新予以配置,研究如何擬訂最佳化之方案。比較結果顯示:(1)有限人力資源配置是影響專案排程的主要原因,規劃求解試算表模式能夠有效解決這個問題,並且計算出最低的人力成本;(2)專案排程的規劃是造成工程能否準時完成的根本原因,根據專案排程的最短完工時間,最短路徑問題未顯著優於要徑法,但是比較專案排程的作業項目有所變動時的方便性,最短路徑問題優於要徑法,最短路徑問題的規劃方法可與規劃求解試算表模式做連結,只要在需要變動的儲存格做出變動,就可以重新求解問題,因此比要徑法規劃方法產生較快速且方便的排程規劃。

English Abstract

Due to ever-tougher worldwide demand for engineering quality control, the construction project scheduling is becoming increasingly prominent. However, with rapid overseas growth of Taiwan-based enterprises, it is a must for them to build local plants, which has gradually complicated issues to consider in project scheduling. In the past, the technology of project scheduling is mainly the critical path method (CPM) and the Program Evaluation and Review Technique (PERT), but in recent years, enterprises in their nonlocal development have often encountered allocation and acquirement problems of human resources. In this way, the single considering scheduling control without taking into account of limited human resources will make infeasible the decisions by enterprises. Therefore, the resource scheduling considering limited human resource allocation will be valued by enterprises. In addition to the allocation of human resources, another challenge is the flow of capital. The previous studies mainly use the CPM and PERT scheduled under the condition of abundant resources, and this practice doesn't consider the costs in the actual operation, will make the original schedule lost the optimality. Therefore, this study under the condition of limited human resources and minimal costs to build an optimized of the Project Scheduling mode to assist decision-makers to plan effectively. This research, referring to the solver method in the management science, constructs a spreadsheet model and applies the shortest path problem as scheduling technique to achieve the objective of minimal cost. This model provides a network optimization problem with integer constraints, which can use simple Excel software for solution. To test the solution effectiveness of this spreadsheet, the research with an existing company as the case study. In 2011, it produced the preliminary budget for the human resources cost of building a plant in the mainland of China in 2012. The research based on data of this project is a case study and re-plans the original resource allocation to find out how to produce the optimal scheme. The comparison results indicate that: (1) the allocation of limited human resources is the main reason affecting the project scheduling, while the spreadsheet mode can efficiently solve this as well as greatly lower the cost of human resources; (2) the planning of project scheduling is the fundamental reason whether the project can be completed in time, based on the shortest completion time in the project scheduling, the shortest path method is not evidently better than the CPM, but comparing the convenience in any change in the project scheduling operation, the shortest path method is better than the CPM, the shortest path problem and solver spreadsheet model can be Combined, and with just changing the desired cells it can solve the problem again. In this way, it can produce reasonable and convenient project planning compared with CPM.
