In the integrated uncapacitated lot sizing and bin packing problem, we have to couple decisions of replenishment from single product suppliers with in delivery client orders. A order is composed quantities each product, such an must be delivered all together no later than a given period. The packed same bin, may advance if it advantageous terms costs. We assume large enough set homogeneous bins...

This paper addresses the independent multi-plant, multi-period, and multi-item capacitated lot sizing problem where transfers between the plants are allowed. This is an NP-hard combinatorial optimization problem and few solution methods have been proposed to solve it. We develop a GRASP (Greedy Randomized Adaptive Search Procedure) heuristic as well as a pathrelinking intensification procedure ...

Coordination of market decisions with other aspects of operations management such as production and inventory decisions has long been a meticulous research issue in supply chain management. Generally, changes to the original lot-sizing policy stimulated by market prices may impose remarkable deviation revenue throughout the supply and demand chain system. This paper examines how to set the chan...

The aim of lot sizing problems is to determine the periods where production takes place and the quantities to be produced in order to satisfy the customer demand while minimizing the total cost. Due to its importance on the efficiency of the production and inventory systems, Lot sizing problems are one of the most challenging production planning problems and have been studied for many years wit...

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...

The current trend among manufacturers is to reduce WIP by decreasing the lot size. Reducing the lot size in some cases may have an adverse effect on system performance because more setup time is incurred. In this paper, we propose the use of queueing network models to determine the best lot-sizing policy that minimizes the WIP. The queueing network model is validated by comparing its results to...

A comparison of methods for lot-sizing in a rolling horizon environment Wilco van den Heuvel • Albert P.M. Wagelmans Econometric Institute and Erasmus Research Institute of Management, Erasmus University Rotterdam, PO Box 1738, 3000 DR Rotterdam, The Netherlands September 2004 We argue that the superior performance of a recent method for lot-sizing in a rolling horizon scheme is to a large exte...
