We analyze a business model for e-supermarkets to enable multi-product sourcing capacity through co-opetition (collaborative competition). The logistics aspect of our approach is to design and execute a network system where ‘‘premium’’ goods are acquired from vendors at multiple locations in the supply network and delivered to customers. Our specific goals are to: (i) investigate the role of pr...

Transport on-demand is an issue in the Vehicle Routing Problem which involves transporting a collection of goods from source (depot) to their destination (customers) and inversely. This paper analyzes forecasts viability using discrete event systems subset this general problem known as pickup delivery problems literature projects on automated manufacturing cell with optimization approach for ve...

This paper addresses the Electric Vehicle Routing Problem with Simultaneous Pickup and Delivery (EVRP-SPD), in which electric vehicles (EVs) simultaneously deliver goods to pick up from customers. Due limited battery capacity of EVs, their range is shorter than that internal combustion vehicles. In EVRP, addition depot customers, there are also charging stations (CS) because EVs need be charged...

This work presents a hybrid approach to solve distribution problem of Portuguese company in the automotive industry. The objective is determine minimum cost for daily operations, such as collecting and delivering goods multiple suppliers. Additional constraints are explicitly considered, time windows loading due limited capacity fleet terms weight volume. An exhaustive review state art was cond...

This paper discusses the vehicle routing problem with simultaneous pickup and delivery (VRPSPD), in which both pickup and delivery tasks simultaneously occur at various customer locations. The objective is to design a set of minimum distance routes with the minimum number of vehicles satisfying all the customers. This paper proposes a heuristic algorithm consisting of a route construction proce...

Vehicle Routing Problem (VRP) is addressed to a class of problems for determining a set of vehicle routes, in which each vehicle departs from a given depot, serves a given set of customers, and returns back to the same depot. On the other hand, simultaneous delivery and pickup problems have drawn much attention in the past few years due to its high usage in real world cases. This study, therefo...

In the stochastic and dynamic multi-stage vehicle routing problem, a set of vehicles collectively transports and services demands which require service at multiple spatially separated locations. Arrival times and service locations of individual demands are not known until the demand’s arrival, and vehicles are assumed to have infinite capacity and to travel with bounded velocity. The objective ...

Vehicle routing problems with pickup and delivery are of primary importance in distribution and logistics. Given a set of non-homogeneous vehicles, which are located at one central depot, the objective is to generate an optimal route plan ensuring that the demand for heterogeneous commodities can be satisfied by an arbitrary set of suppliers. Owing to their physical property, commodities have t...

The location routing problem with simultaneous pickup and delivery (LRPSPD) is a new variant of the location routing problem (LRP). The objective of LRPSPD is to minimize the total cost of a distribution system including vehicle traveling cost, depot opening cost, and vehicle fixed cost by locating the depots and determining the vehicle routes to simultaneously satisfy the pickup and the delive...

We address a single commodity Pickup and Delivery Vehicle Routing Problem from the literature. A network of customer nodes is given with both travel times costs. fleet vehicles limited capacity exploited to satisfy node demands, set routes must be found such that vehicle capacities are never exceeded, each route does not exceed time resource, cost minimized. The demands pickup delivery can spli...
