"城市快速的生活步調讓城市配送變成艱難複雜的工作，城市居民討厭等待且喜好即時的服務，因此，發展出兩種創新城市配送方式減輕顧客的等待負擔、滿足顧客的即時需求並提升配送的效率。雖然全球許多城市已經建置創新城市配送系統，但過去研究探討創新城市配送系統規劃之文章確非常少。因此，這一個二年期的研究計畫的目標，在於探討規劃創新城市配送系統，建構考慮考量服務水準的創新城市配送系統規劃模式，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智能取貨櫃數量決策之城市最後一哩配送系統規劃模式，並發展出分枝價格演算法(Branch-and-Price Algorithm)求解。模式主要的決策變數有智能取貨站的數目及區位、在智能取貨站配置的智能取貨櫃數量、及配送路徑選擇。第二年計畫的目的在考量運務員規模及運務員最少工作量平衡限制下，建構群眾外包配送系統規劃模式，並發展出運算負荷上可行之演算法求解此規劃問題及探討運務員規模及運務員最少工作量的權衡。模式主要的決策變數為運務員規模、及在每一期中：每一服務內運務員總數、運務員調度及貨物運送。""The frenetic pace of urban living style has transformed urban delivery into a very intricate engineering task. Nowadays customers hate waiting for delivery and prefer their service immediately or with a short delay. Two innovative urban delivery systems have been developed to lessen customer’s burden of waiting, to meet customer’s immediate need, and to enhance the efficiency of delivery. Despite of growing interest in cities around the world, there are relatively few studies published on the planning of innovative urban delivery systems. This encourages us to carry out this two-year study to address the logistics issues concerned by customers in the planning of innovative urban delivery systems. The purpose of this first year project is to formulate and analyze a robust planning model for last-mile delivery systems with locker storage space capacity considerations. The key planning decisions considered are: the number and locations of locker stations in the system, the number of lockers to be held at the locker stations and the routing of shipments through a locker station between parcels distribution centers and customer locations. The planning decisions are made with concern for both total cost and service level (measured both by fill rate for shipments storages at the locker station and coverage of the customers). 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 purpose of the second-year project is to formulate and analyze a crowdsourced same-day courier planning model for urban on-demand delivery systems where are constrained by the courier size. The key planning decisions considered are: the number of couriers at each service zone in each period, how the available couriers should be repositioned to replenish the courier pool at each service zone for hire and how to dispatch the couriers to serve the immediate service requests. The planning decisions are made with concerns for the revenue of serving demand, the operation costs of running the system and service levels (measured by unmet demand in each period).The optimal planning of this system requires an integrated view of the ownership costs of courier, the reposition strategy of un-hired courier and the dispatching strategy of couriers. The purpose of this project is to create a formal model that provides such an integrated view, and to develop methods for obtaining solutions for the planning variables in practical situations."
