【論文摘要】考量時窗限制內之多階狀態鐵路運輸網路可靠度評估
【論文摘要】Reliability Evaluation of a Multistate Railway Transportation Network within Time Window Constraint
摘要
近年來，人們對生活品質的重視，旅遊成為生活不可或缺的一環，而鐵路運輸則為多數人旅遊時考量的主要運具，導致每逢假期時，鐵路運輸系統不易負荷龐大數量的旅客，而經常造成班車延誤與旅客抱怨。因此本研究提出網路可靠度做為評估鐵路運輸系統（railway transportation system）之服務績效指標，並定義其為鐵路運輸系統得以於特定時窗內能夠滿足旅客從起站至訖站的機率，以作為旅行業者於接待團體旅客時之參考。本研究依據鐵路的排班時刻資訊系統，建構多階狀態鐵路運輸網路（multistate railway transportation network, MRTN）模型，其中列車停靠站視為網路中之節點，連接兩停靠站間的傳輸邊則表示行駛於兩站間之列車，由於列車座位可能被其他乘客事先預訂以及團體旅客偏好預訂整個車廂，使得各列車當下可提供空座位車廂的數量呈現多階狀態且對應一機率分配。為求算此網路可靠度，本研究以最小路徑的概念發展一鐵路運輸網路可靠度評估之演算法，並以蒐集自臺灣鐵路管理局的資料，來演示所提出演算法之程序，並根據所得之可靠度，進一步探討旅行業者的管理意涵。

In recent years, people gradually focus on the quality of life. Travel plays an indispensable role in our life, and the railway is the main transport means for the travelers because of its convenience. It's difficult to carry a large number of passengers for the railway transportation system, especially on holidays and special festivals. In addition, delay usually occurs in the system and causes much complaint from passengers. For the purpose to measure whether the railway transportation system can meet travel demand, this research focuses on evaluating network reliability which can be treated as a service performance index of a railway transportation from the perspective of travel agency and group booking. A railway transportation system can be modeled as a multistate railway transportation network (MRTN), in which each node represents a station and each arc denotes the trains carrying passengers between a pair of stations. In general, group tours prefer to book the entire carriages. However, the number of available carriages are multistate because the seats may be partially reserved by other passengers. In order to consider the scheduled departure and arrival time on the traveler's itinerary, herein, the reliability of a multistate railway transportation network is defined as the probability that a requested number of passengers can be carried successfully within time window constraint. An algorithm is proposed in terms of minimal paths to calculate network reliability. Finally, a case study of the Taiwan Railway Transportation System is utilized to present how to implement the proposed algorithm and discuss the managerial implications of tourism further.
