Economic tradeoffs in sizing warehouse reserve storage area

The forward reserve warehouse sizing and dimensioning problem

The discrete forward-reserve problem - Allocating space, selecting products, and area sizing in forward order picking

To reduce labor-intensive and costly order picking activities, many distribution centers are subdivided into a forward area and a reserve (or bulk) area. The former is a small area where most popular stock keeping units (SKUs) can conveniently be picked, and the latter is applied for replenishing the forward area and storing SKUs that are not assigned to the forward area at all. Clearly, reduci...

Economic lot-sizing games

In this paper we introduce a new class of OR games: economic lot-sizing (ELS) games. There are a number of retailers that have a known demand for a fixed number of periods. To satisfy demand the retailers order products at the same manufacturer. By placing joint orders instead of individual orders, costs can be reduced and a cooperative game arises. In this paper we show that ELS games are bala...

Economic Lot Sizing and Scheduling in Distributed Permutation Flow Shops

This paper addresses a new mixed integer nonlinear and linear mathematical programming economic lot sizing and scheduling problem in distributed permutation flow shop problem with number of identical factories and machines. Different products must be distributed between the factories and then assignment of products to factories and sequencing of the products assigned to each factory has to be d...

Energy Storage Siting and Sizing in the WECC Area and the CAISO System

Spatio-temporal arbitrage using energy storage systems reduces the cost of operating a power system. However, since the cost of deploying storage is significant, it is essential to determine the optimal locations and ratings of these systems. This paper proposes a stochastic storage siting and sizing method that determines the optimal locations and ratings. This is first done from a centralized...
