Due to the diversity and different distribution conditions of agricultural products, split delivery plays an important role in last mile products distribution. The time-dependent green vehicle routing problem with multiple time windows (TDSDGVRPMTW) is studied by considering both economic cost customer satisfaction. A calculation method for road travel across periods was designed. satisfaction ...

over the two last decades, distribution companies have been aware of the importance of paying attention to the all aspects of a distribution system simultaneously to be successful in the global market. these aspects are the economic, the environmental, the social and the safety aspects. in the vehicle routing problem (vrp) literature, the economic issue has often been used, while the environmen...

This paper introduces a new model of the customer-centric, two-product split delivery vehicle routing problem (CTSDVRP) in context mixed-flow manufacturing system that occurs power industry. Different from general VRP model, unique characteristics our are: (1) two types products are delivered, and demand for them is interdependent based on bill materials (BOM); (2) considers aspect customer sat...

A capacitated location-routing problem (CLRP) is one of the new areas of research in distribution management. It consists of two problems; locating of facilities and routing of the vehicle with a specific capacity. The purpose of the CLRP is to open a set of stores, allocate customers to established deposits, and then design vehicle tours in order to minimize the total cost. In this paper, a ne...

A considerable amount of research has been concerned with the domain of automatic planning and scheduling, but many real world scheduling problems such as The Pick up and Delivery Problem With Time Windows (PDPTW) are still not easily tackled. The PDPTW problem demands solving the schedule for each vehicle of a transportation fleet where pick up and delivery of customer orders are distributed a...

Solving the Vehicle Routing Problem (VRP) and its related variants is significant for optimizing logistic planning. One important variant of the VRP is the Pickup and Delivery Problem with Time Windows (PDPTW), where it is assumed that a client may request one of two service types, a pickup or a delivery. It is required to find a set of minimum cost routes for a fleet of vehicles, while observi...

The multi-depot pickup and delivery problem with heterogeneous fleet and soft time windows (MDPDPHSTW) requires to find a minimum cost routing for a fleet vehicles with different capacities and based at different depots, satisfying a given set of customers. A customer request is associated with two locations: a source where a certain demand must be picked up and a destination where this demand ...

We study an extension to the general routing problem, which deals with integrating fixed route service with the general pickup and delivery problem to create a hybrid routing problem. The primary application for such a service is a dial-a-ride system used by transit agencies to transport disabled or elderly individuals. The main aim of the integration is to reduce the vehicle miles of the on-de...
