We consider a manufacturer who manages the end-of-life phase and takes one of three actions at each period: (1) place an order, (2) use existing inventory, (3) stop holding inventory outside/alternative source. Two examples this source are discounts for new generation product delegating operations. Demand is described by non-homogeneous Poisson process, decision to stopping time. After formulat...

This study dives deep into a lateral supply chain network for perishable food products and aims to determine optimal re-order order up levels multiple e-groceries within common using simulation-based optimization technique. The algorithm minimize the average inventory carried while accounting parameters like reduced wastage, improved customer satisfaction level, limited number of replenishments.

When an enterprise has thousands of varieties in its inventory, the use of a single management method could not be a feasible approach. A better way to manage this problem would be to categorise inventory items into several clusters according to inventory decisions and to use different management methods for managing different clusters. The present study applies DPSO (dynamic particle swarm opt...

This paper presents a solution method based on column generation for the Inventory Location Routing Problem. It chooses simultaneously the location of a set of depots to decide upon the inventory management and the set of routes to satisfy customers’ demands, in order to minimize the total system cost. The original problem is decomposed into a Master Problem (Location Problem) and an Auxiliary ...

We study a two-level uncapacitated lot-sizing problem with inventory bounds that occurs in a supply chain composed of a supplier and a retailer. The first level with the demands is the retailer level and the second one is the supplier level. The aim is to minimize the cost of the supply chain so as to satisfy the demands when the quantity of item that can be held in inventory at each period is ...

Reducing manufacturing lead times and minimizing work-in-process (WIP) inventories are the cornerstones of popular manufacturing strategies such as Lean, Quick Response, and Just-inTime Manufacturing. In this paper, we present a model that captures the relationship between facility layout and congestion-related measures of performance. We use the model to introduce a formulation of the facility...

We consider an inventory system in which inventory level fluctuates as a Brownian motion in the absence of control. The inventory continuously accumulates cost at a rate that is a general convex function of the inventory level, which can be negative when there is a backlog. At any time, the inventory level can be adjusted by a positive or negative amount, which incurs a fixed cost and a proport...

Market segmentation is an essential element of marketing in industrialized countries. Goods can no longer be produced and sold without considering customer needs and recognized the heterogeneity of these needs. In this paper, we use market segmentation approach in single product inventory system with deteriorating items. The objective is to make use of optimal control theory to solve the produc...
