Vendor managed resupply is an emerging trend in logistics and refers to a situation in which a supplier manages the inventory replenishment of its customers. Vendors save on distribution cost by being able to better coordinate deliveries to different customers, and customers do not have to dedicate resources to inventory management anymore. We present and discuss the inventory routing problem. ...

In this paper, a problem of managed inventory by the vendor in production-distribution supply chain is presented based on scenario. The main purpose presenting model maximizing producer profit three-level network consisting various strategic and tactical decisions under uncertainty. Due to nonlinearity NP-Hardness problem, meta-heuristic genetic algorithms, Whale optimization algorithm league c...

This paper investigates a multi-period multi-product stochastic inventory problem in which cash-constrained online retailer can leverage order-based loans provided by some Chinese e-commerce platforms to speed up its cash recovery for deferred revenue. Sample average approximation (SAA) and moment-matching scenario tree are adopted solve this multi-stage with the objective of maximising retaile...

We consider an application of the inventory routing problem. A fleet of vehicles is devoted to collecting a single product from geographically dispersed sites. Each site has its own accumulation rate and stock capacity. On each visit, the vehicle empties the stock. At the tactical level, the objective is to minimize the fleet size and an estimate of the distance travelled. Moreover, for practic...

Reinforcement Learning (RL) can solve practical sequential decision problems, even when structures of the problems are less understood. However, some sequential decision problems intrinsically have structural parts that are easily to formulate and distinguish from less understood parts. Exploiting this knowledge may help improve performance of RL. This study proposed and investigated an approac...

In this paper, we consider the batch arrival of customers to a transport station. Customers belonging each category is considered as single entity according BMMAP. An Erlang clock order m starts ticking when vessel reaches When Lth stage reached, an for next placed. The lead time follows exponential distribution. There are two types rooms in system: waiting and service station vessel, respectiv...
