Setup Adjustment Under Unknown Process Parameters and Fixed Adjustment Cost
Consider a machine that can start production off-target where the initial offset is unknown and unobservable. The goal is to determine the optimal series of machine adjustments that minimize the expected value of the sum of quadratic off-target costs and fixed adjustment costs. Apart of the unknown initial offset, the process is supposed to be in a state of statistical control, so the process m...
متن کاملReducing the Setup Time of a One-Step FDTD Method
As society places greater demands on technology, it becomes increasingly important to be able to simulate that technology. While simulation tools can be very sophisticated and capable of handling very complex devices and structures, the cost paid in computation time can be prohibitive. To reduce this time, a number of one-step schemes have been developed, but these schemes suffer from a setup t...
متن کاملProcess setup adjustment with quadratic loss
A classic adjustment method, the harmonic adjustment rule, minimizes expected quadratic loss where adjustments are easy and cheap, and the items produced during the adjustment process should be as close to target as possible. This paper generalizes the harmonic adjustment rule by explicitly taking into account measurement and adjustment costs. The generalization is static, in that adjustments a...
متن کاملREDUCING SETUP COST BY AUTOMATED GENERATION OF REDESIGN SUGGESTIONSDiganta
All mechanical designs pass through a series of formal and informal redesign steps, involving the analysis of func-tionality, manufacturability, cost and other life-cycle factors. The speed and eecacy of these steps has a major innuence on the lead time of the product from conceptualization to launching. In this paper we propose a methodology for automatically generating redesign suggestions fo...
متن کاملThe Effect of Adjustment Costs and Organizational Change on Productivity in Canada: Evidence from Aggregate Data
A basic neoclassical model of production is often used to assess the contribution of investment to output growth. In the model, investment raises the capital stock and output growth increases in proportion to the growth in capital. It has been argued, however, that computers, as a “general purpose technology,” lead to process innovations and facilitate organizational coinvestments. Since there ...
