M-GSPRT APPROACH TO THE DEVELOPMENTAL OF ITS/CVO STRATEGIC ANALYSIS

[[abstract]]商車營運系統(Intelligent Transportation Systems/Commercial Vehicle Operation; ITS/CVO)乃運用智慧型運輸系統中之各項先進技術於商車相關營運服務，以提升商用車輛營運之效率與安全。 本研究在一開始發展出ITS/CVO價值鏈後，搭配策略型態組合而成策略矩陣，並以此為基礎來設計問卷，而最後則是透過M-GSPRT(一般化序列機率比檢驗法)佐以貝斯估計法來分析問卷結果。並針對ITS/CVO總體面、供給導向與需求導向等三大層面，研擬短、中、長期之發展策略。 重要研究結果如下： 1. 總體面之短期價值鏈活動，僅有車隊管理一項；中期則有資料倉儲、資訊科技、貨運機動性、與ATMIS整合，與供應鏈作連結與整合、複合運輸之延伸等六項價值鏈活動；長期則有貨運行政、危險資材事故管理、即時安全自動偵測，路邊安全檢視等四項價值鏈活動。 2. 供給導向之短期價值鏈活動有車隊管理，與供應鏈作連結與整合二項；中期則有資料倉儲、資訊科技、貨運行政、危險資材事故管理、貨運機動性、與ATMIS整合、複合運輸之延伸等七項價值鏈活動；長期則有即時安全自動偵測、路邊安全檢視等二項價值鏈活動。 3. 需求導向之短期價值鏈活動有資料倉儲、車隊管理、貨運機動性等三項；中期則有資訊科技、貨運行政、危險資材事故管理、路邊安全檢視，與ATMIS整合，與供應鏈作連結與整合，複合運輸之延伸等七項價值鏈活動；長期則有即時安全自動偵測一項價值鏈活動。[[abstract]]Commercial Vehicle Operations (CVO) is a program designed to implement new and existing technologies and services aimed at improving safety ,and increasing efficiency. Our study explores a new sequential decision methodology which integrates a generalized sequential probability ratio testing approach with a strategy-value matrix analytical tool to determine the developmental priorities of commercial vehicle operation (CVO) technical packages for CVO time-based strategic planning. Utilizing the proposed method ,we determined efficiently the developmental priorities of CVO technology packages for short-term ,mid-term ,and long-term strategic plans in three domains. The main results are as follows: 1.In general analysis: our results indicated that fleet management appears to be the most urgently needed in the short-term CVO strategic plan ;value-added technology packages including data warehousing ,information technology ,integration with the supply chain management (SCM) platform ,freight mobility ,integration with advanced traffic management systems (ATMS) ,and extension for intermoal operations are assigned to the mid-term CVO strategic plan; and others including freight administration ,HAZMAT management ,on-board safety monitoring and roadside safety inspections are involved in the long-term CVO strategic plan. 2.Supply orientation : our results indicated that fleet management ,and integration with the SCM platform appears to be needed in the short-term ;value-added technology packages including data warehousing ,information technology ,freight administration ,HAZMAT management ,freight mobility ,integration with ATMS ,and extension for intermal operations are assigned to the mid-term CVO strategic plan ; and others including on-board safety monitoring ,and roadside safety inspections are involved in the long-term CVO strategic plan. 3.Demand orientation : our results indicated that fleet management ,data warehousing ,and freight mobility appears to be needed in the shout-term CVO strategic plan ;value-added technology packages including information technology ,freight administration ,HAZMAT management ,roadside safety inspections ,integration with ATMS ,integration with the SCM platform ,and extension for intermodal operations are assigned to the mid-term CVO strategic plan ;and on-board safety monitoring is involved in the long-term CVO strategic plan
