Crowdsourced Delivery: A Dynamic Pickup and Delivery Problem with Ad-hoc Drivers

The trend towards shorter delivery lead-times reduces operational efficiency and increases transportation costs for internet retailers. Mobile technology, however, creates new opportunities to organize the last-mile. In this paper, we study the concept of crowdsourced delivery that aims to use excess capacity on journeys that already take place to make deliveries. We consider a peer-to-peer platform that automatically creates matches between parcel delivery tasks and ad-hoc drivers. The platform also operates a fleet of backup vehicles to serve the tasks that cannot be served by the ad-hoc drivers. The matching of tasks, drivers and backup vehicles gives rise to a new variant of the dynamic pick-up and delivery problem. We propose a rolling horizon framework and develop an exact solution approach to solve the various subproblems. In order to investigate the potential benefit of crowdsourced delivery, we conduct a wide range of computational experiments. The experiments provide insights into the viability of crowdsourced delivery under various assumptions about the environment and the behavior of the ad-hoc drivers. The results suggest that the use of ad-hoc drivers has the potential to make the last-mile more cost-efficient and can reduce the system-wide vehicle-miles

Streamlining deliveries through crowdsourcing

Internet shopping is taking an increasing share of the retail market, putting pressure on retailers to slash delivery times and to get products to customers quickly. This reduces operational efficiency and increases transportation costs for retailers with dedicated fleets of delivery vans. Using crowdsourced deliveries by ad-hoc external parties could offer a cost-effective solution

Penentuan Rute Terbaik Pendistribusian Gas Industri menggunakan Algoritma Ant Colony Optimization ( Studi Kasus di PT. Samator Gas Industri, Kudus)

Abstrak – Penentuan rute terbaik pendistribusian dapat dilakukan untuk meningkatkan performance dalam proses distribusi. Utilisasi truk di PT Samator Gas Industri saat ini masih rendah yaitu 61,24% dari kapasitas maksimum truk 7000 kg. Penelitian ini bertujuan untuk menentukan rute terbaik pendistribusian gas industri di PT Samator Gas Industri untuk meminimasi jarak tempuh kendaraan dan penghematan biaya bahan bakar serta memaksimalkan utilisasi truk dengan batasan Capacitated Vehicle Routing Problem with Pickup and Delivery for Multiple Products dengan Dynamic Demand yang diselesaikan dengan metode pendekatan algoritma Ant Colony Optimization (ACO). Penelitian ini mempertimbangkan 2 jenis layanan pendistribusian yaitu pickup and delivery dengan batasan kapasitas kendaraan yang homogen. Penelitian ini menggunakan menggunakan 2 kelompok relasi meningkatkan utilisasi truk sebesar 91,86%, menurunkan persentase total jarak tempuh sebesar 15,589% menjadi 398.12 km perhari dari yang sebelumnya 324.11 km perhari, dan penghematan kebutuhan biaya bahan bakar sebesar 15,589%

A simulation-based evaluation of a Cargo-Hitching service for E-commerce using mobility-on-demand vehicles

Time-sensitive parcel deliveries, shipments requested for delivery in a day or less, are an increasingly important research subject. It is challenging to deal with these deliveries from a carrier perspective since it entails additional planning constraints, preventing an efficient consolidation of deliveries which is possible when demand is well known in advance. Furthermore, such time-sensitive deliveries are requested to a wider spatial scope than retail centers, including homes and offices. Therefore, an increase in such deliveries is considered to exacerbate negative externalities such as congestion and emissions. One of the solutions is to leverage spare capacity in passenger transport modes. This concept is often denominated as cargo-hitching. While there are various possible system designs, it is crucial that such solution does not deteriorate the quality of service of passenger trips. This research aims to evaluate the use of Mobility-On-Demand services to perform same-day parcel deliveries. For this purpose, we use SimMobility, a high-resolution agent-based simulation platform of passenger and freight flows, applied in Singapore. E-commerce demand carrier data are used to characterize simulated parcel delivery demand. Operational scenarios that aim to minimize the adverse effect of fulfilling deliveries with Mobility-On-Demand vehicles on Mobility-On-Demand passenger flows (fulfillment, wait and travel times) are explored. Results indicate that the Mobility-On-Demand services have potential to fulfill a considerable amount of parcel deliveries and decrease freight vehicle traffic and total vehicle-kilometers-travelled without compromising the quality of Mobility On-Demand for passenger travel.Comment: 19 pages, 4 tables, 7 figures.

Where is my parcel? A review of crowd logistics revolution in Malaysia

This research aims to explore the crowd logistics concept and discover crowd logistics evolution in the Malaysia logistics industry. Employs a systematic literature review approach by using PICo or mnemonic, which signifies ‘P’ (Population or Problem), ‘I’ (Intervention or Exposure) and ‘Co’ (Context). This paper evaluates the evolution of crowd logistics in Malaysia starting with conventional logistics, the introduction of raid hailing, last-mile delivery, crowd logistic and the future of crowd intelligence. The history of crowd logistics expansion has become prominent with the integration of technology and existing infrastructure which allows greater flexibility, customization and efficiency in logistics and transportation delivery. Addressing the crowd logistics revolution has shaped the development of future crowd logistics to be available in the supply chain and maximize the value creation in the Malaysia logistics industry
