1 The Economic Lot Scheduling Problem
Economies of scale often dictate the choice of a single high speed machine capable of producing a given set of items over the choice of one dedicated machine for each item in the set. A scheduling problem arises when the high speed machine can only produce one item at a time. The problem is further complicated when the machine needs to be setup (often at a cost of both time and money) before a ...
متن کاملThe Economic Lot Scheduling Problem in Flow Lines with Sequence-Dependent Setups
The problem of lot sizing, sequencing and scheduling multiple products in flow line production systems has been studied by several authors. Almost all of the researches in this area assumed that setup times and costs are sequence –independent even though sequence dependent setups are common in practice. In this paper we present a new mixed integer non linear program (MINLP) and a heuristic me...
متن کاملThe Finite Horizon Economic Lot Scheduling in Flexible Flow Lines
This paper addresses the common cycle multi-product lot-scheduling problem in flexible flow lines (FFL) where the product demands are deterministic and constant over a finite planning horizon. Objective is minimizing the sum of setup costs, work-in-process and final products inventory holding costs per time unite while satisfying the demands without backlogging. This problem consists of a combi...
متن کاملAn Evolutionary Computation Approach to the Economic Lot Scheduling Problem
The economic lot scheduling problem (ELSP) addresses the problem of scheduling several items each with its own static, deterministic demand at a single facility, where only one item can be produced at any time. This classical production planning problem has been studied extensively over the last three decades and various heuristic solution methods have been proposed, most of them based on the c...
متن کاملSimulation Optimization for the Stochastic Economic Lot Scheduling Problem
We study simulation optimization methods for the stochastic economic lot scheduling problem. In contrast to prior research, we focus on methods that treat this problem as a black box. Based on a large-scale numerical study, we compare approximate dynamic programming with a global search for parameters of simple control policies. We propose two value function approximation schemes based on linea...
