"全球持續增加對氣候變遷及能源安全性關注，引起全球許多城市對建置永續運輸模式--如公共自行車系統的構想。雖然全球許多城市對建置公共自行車系統的構想持續增加，過去研究探討公共自行車系統規劃之文章確非常少。因此，這一個三年期的研究計畫的目標，在於探討規劃公共自行車系統使用者關注議題，建構考慮使用者關注議題的公共自行車系統模式，並發展可行之求解方法，探討求解之品質。第一年計畫的目的在建構及分析同時考量服務水準及公共自行車存貨決策之公共自行車系統規劃模式，並發展出Branch-and-Price 演算法求解。模式主要的決策變數有公共自行車站之數目及區位、介於自行車站間之自行車道建置、使用者在起迄點的路徑選擇及在自行車站存放自行車數目。第二年計畫的目的在建構及分析同時考量公共自行車存貨及公共自行車停車位決策之公共自行車系統策規劃模式。因此規劃模式為非線性整數規劃，本研究擬發展混合式啟發演式算法求解此規劃問題。第三年計畫的目的在建構及分析同時考量所有使用者關注議題公共自行車系統策規劃模式。規劃模式考慮道路路網、使用者路徑選擇、騎乘安全性及規劃妥善度等因素，因此規劃模式為双層數學規劃，本研究擬發展出混合式啟發演式算法求解此規劃問題。""Global growing concerns over climate change and energy security have lead to an explosive interest in sustainable transportation modes such as bicycle sharing. Despite of growing interest in cities around the world, there are relatively few studies published on the planning of public bicycle sharing systems. This encourages us to carry out this three-year study to address the logistics issues concerned by users in the planning of public bicycle sharing systems. The purpose of this first year project is to formulate and analyze a planning model for public bicycle sharing systems with service levels and bicycle stocks considerations. The key planning decisions considered are: the number and locations of bicycle stations in the system, the creation of bicycle lanes between bicycle stations, the selection of paths of users between origins and destinations, and the inventory levels of sharing bicycles to be held at the bicycle stations. A closed inventory analysis is developed to determining the required bicycle stocks at bicycle stations to ensure the desired service levels. The planning problem is formulated as a hub location inventory model. A branch-and-price algorithm will be then developed for instances of realistic size. The quality of solutions to a series of test problems will be evaluated. The second-year project focuses on formulating and analyzing a planning model for public bicycle sharing systems with service levels and both bicycle stocks and rack space considerations. The key planning decisions considered are: the number and locations of bicycle sharing stations in the system, the creation of bicycle lanes between bicycle stations, the selection of paths of users between origins and destinations, the inventory levels of sharing bicycles to be held at the bicycle stations, and the rack space to be installed at the bicycle stations. Based on queuing theory, an analysis for determining the required bicycle stocks and rack space is developed. A non-linear mathematical programming is then presented. So we will propose a hybrid meta-heuristic method for solving the problem. A post-optimization simulation study will be carried out to verify the analysis of inventory levels and rack space. The third-year project focuses on formulating and analyzing an integration planning model for public bicycle sharing systems addressing all five logistic issues concerned by users. A multi-objective bi-level mathematical programming formulation of the problem is presented. The key planning decisions in the upper level programming considered are: the number and locations of bicycle sharing stations in the system, the creation of bicycle links on the street network between bicycle stations, the inventory levels of sharing bicycles to be held at the bicycle stations, and the rack space to be installed at the bicycle stations. The upper level planning decisions are made with concern for the systems costs, the user un-safety levels and the undesired planning levels. The key user choices decisions in the lower level programming considered are the user choices on routes. A hybrid meta-heuristic method will be developed for solving the problem. The quality of solutions to a series of test problems will be evaluated."
