Based on the introduction of the new adaptive probability for chromosome cross and chromosome mutate, this paper presents a new method for constructing chromosome. A new genetic algorithm for an integrated model of a single finished product VMI (Vendor Managed Inventory) system considering markets and one level BOM (Bill of Materials) is developed. An example is given to illustrate the converge...

Improvement in supply chain performance is one of the major issues in the current world. Lack of coordination in the supply chain is the main drawback of supply chain that many researchers have proposed different methodologies to overcome it. VMI (Vendor-managed inventory) is one of these methodologies that implementing it has some obstacles. This paper proposes new model that is agent-managed ...

This paper considers the performance of a production or distribution-scheduling algorithm termed Automatic Pipeline, Inventory and Order Based Production Control System (APIOBPCS) embedded within a Vendor Managed Inventory (VMI) supply chain where the demand profile is deemed to change significantly over time. A dynamic model of the system using causal loop diagrams and difference equations is ...

For the best implementation of (vendor-managed inventory) VMI, a vendor must choose optimal combination suppliers that can better meet criteria environmental problems. In controls some retailers' inventory decisions. This study aims to select in green VMI and assign orders them. this study, selects by accounting for various factors, including quality delivery reliability, reduction return perce...

I n this paper we consider a cooperative, two-level supply chain consisting of a retailer and a supplier. As in many practical settings, the supply chain members progressively observe market signals that enable them to explain future demand. The demand itself evolves according to an auto-regressive time series. We examine three types of supply chain configurations. In the first setting, the ret...

This paper studies a single-product supply chain, in which the supplier needs to manage its own inventory to fulfill requests from a set of heterogonous retailers. The retailers’ requests are determined by the supplier in a fashion of vendor-managed inventory (VMI). Under a VMI arrangement, the supplier agrees to pay all the order setup costs and a portion of unit holding costs for the retailer...

This paper examines the relationship between distributor backorder performance and its inventory levels under Vendor Managed Inventory (VMI) in a supply chain that consists of distributors and manufacturers. We construct a principal-agent model to show that distributors' inventory managed by manufacturers can be used to induce distributor efforts, which are unobservable to the manufacturers, in...

This paper models a type of vendor-managed inventory (VMI) agreement that occurs in practice called a (z, Z) contract. We investigate the savings due to better coordination of production and delivery facilitated by such an agreement. The optimal behavior of both the supplier and the retailer are characterized. The optimal replenishment and production policies for a supplier are found to be up-t...
