An Improvement of Joint Ordering Policy of Multiproduct Inventory Problem with Partial Joint Ordering

Coordinated and Joint Ordering Policies for Two Commodity Inventory System

A multiple objective approach for joint ordering and pricing planning problem with stochastic lead times

The integration of marketing and demand with logistics and inventories (supply side of companies) may cause multiple improvements; it can revolutionize the management of the revenue of rental companies, hotels, and airlines. In this paper, we develop a multi-objective pricing-inventory model for a retailer. Maximizing the retailer's profit and the service level are the objectives, and shorta...

Constraint multiproduct joint-replenishment inventory control problem using uncertain programming

An uncertain economic order quantity (UEOQ) model with payment in advance is developed to purchase high-price raw materials. A joint policy of replenishments and pre-payments is employed to supply the materials. The rate of demand is considered LR-fuzzy variables, lead-time is taken to be constant, and it is assumed that shortage does not occur in the cycles. The cycle is divided into three par...

An Evolutionary Algorithm for the Joint Replenishment of Inventory with Interdependent Ordering Costs

The joint replenishment of inventory problem (JRP) requires independence of minor ordering costs. In this paper we propose an evolutionary algorithm (EA) for a modification of the JRP. The modified JRP allows for interdependence of minor ordering costs. Our proposed EA (EARP) is a nested EA that searches for a solution to minimize the total cost of inventory replenishment. It combines an EA whi...

Joint Ordering and Inspection Policy for a Multi-period Inventory System Subject to Shrinkage Errors

One of the implicit assumptions considered in the majority of investigations performed in the area of inventory management is that the physical flow of products that passes through an inventory system as well as the associated information flow are free from defects, i.e. for a given type of product, the quantity received matches exactly the quantity ordered or there are no errors occurring duri...
