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 کاملA Basic Period Approach for Solving the Economic Lot and Delivery Scheduling in Flexible Flow Lines
In this paper, the problem of lot sizing, scheduling and delivery of several items in a two-stage supply chain over a finite planning horizon is studied. Single supplier via a flexible flow line production system (FFL), produces several items and delivers them directly to an assembly facility. Based on basic period (BP) strategy, a new mixed zero-one nonlinear programming model has been develop...
متن کاملFinite Horizon Economic Lot and Delivery Scheduling Problem: Flexible Flow Lines with Unrelated Parallel Machines and Sequence Dependent Setups
This paper considers the economic lot and delivery scheduling problem in a two-echelon supply chains, where a single supplier produces multiple components on a flexible flow line (FFL) and delivers them directly to an assembly facility (AF). The objective is to determine a cyclic schedule that minimizes the sum of transportation, setup and inventory holding costs per unit time without shortage....
متن کاملThe Stochastic Economic Lot Scheduling Problem: Heavy Traffic Analysis of Dynamic Cyclic Policies
We consider two queueing control problems that are stochastic versions of the economic lot scheduling problem: A single server processes N customer classes, and completed units enter a 'nished goods inventory that services exogenous customer demand. Unsatis'ed demand is backordered, and each class has its own general service time distribution, renewal demand process, and holding and backorderin...
متن کاملThe Stochastic Economic Lot Scheduling Problem: Cyclical Base-Stock Policies with Idle Times
In this paper we discuss stochastic Economic Lot Scheduling Problems (ELSP), i.e., settings where several items need to be produced in a common facility with limited capacity, under significant uncertainty regarding demands, production times, setup times, or combinations thereof. We propose a class of production/ inventory strategies for stochastic ELSPs and describe how a strategy which minimi...
