Optimal asymmetric tolerance design
Tập 32 - Trang 1127-1137 - 2000
An asymmetric tolerance design occurs when deviation (from the ideal target) of
a quality characteristic in one direction is more harmful than in the opposite
direction. Asymmetric tolerances are common in many manufacturing processes.
Traditionally, the designer of a manufactured component either would choose the
smaller tolerance as the tolerance for both sides of the ideal target, or would
set ...
Negotiating price/delivery date in a stochastic manufacturing environment
Tập 31 - Trang 255-270 - 1999
We study a make-to-order manufacturing system consisting of several processing
centers that are subject to failures and repairs. Our objective is to build a
model that can be used as a tool for negotiating the delivery date and the price
of a certain upcoming order. The model takes into account the congestion level
of the shop floor at the time the order is placed. Based on the workload of the
pro...
Assessing multivariate process/product yield via discrete point approximation
- 1998
The assessment of multivariate yield is central to the robust design of
products/processes. Currently, yield is evaluated via Monte Carlo simulation.
However, it requires thousands of replications per simulation to achieve an
acceptably precise estimate of yield, this is often tedious and time consuming,
thereby rendering it unattractive as an evaluation tool. We propose a discrete
point approxima...
Allocation of test times in multi-state systems for reliability growth testing
- 2002
This paper generalizes a reliability growth test allocation problem to
series–parallel multi-state systems. An algorithm, which determines the testing
time for each system element in order to maximize the entire system reliability
when total testing resources are limited, is suggested. The algorithm can handle
both repairable and non-repairable multi-state systems. The Crow/AMSAA
reliability growt...
A methodology for quantifying the effects of product development on cost and time
Tập 31 - Trang 365-378 - 1999
This paper demonstrates a methodology to quantify past product development
efforts in an attempt to better utilize past experiences. The methodology is
centered around conducting an observational study, using regression analysis, to
expose relationships between various aspects of past product development
efforts, including cost and time. The applicability of the methodology is
demonstrated by pres...
A Flexible Simulation Tool for Manufacturing-cell Design
Tập 33 - Trang 837-846 - 2001
We present a two-phase approach to design and analysis of manufacturing cells
based on simulated experimentation and response surface methodology using a
general manufacturing-cell simulation model. The first phase involves
factor-screening simulation experiments to identify design and operational
factors that have a significant effect on cell performance as measured by a
comprehensive annual cost...
A comparison of existing grouping efficiency measures and a new weighted grouping efficiency measure
Tập 33 - Trang 11-27 - 2001
Grouping efficiency is an evaluative measure of the machine-part groups in
cellular manufacturing systems. This paper presents briefly both a critical
review and a comparative study of different measures of grouping efficiency.
Special emphasis is given to the evaluation of the goodness of clustering
solutions in the block-diagonalization of the machine-part incidence matrix. The
measures are repo...
Lot streaming with attached setups in three-machine flow shops
Tập 30 - Trang 1075-1084 - 1998
Lot streaming is the process of splitting a job or lot to allow overlapping
between successive operations in a multistage production system. This use of
transfer lots usually results in a significantly shorter makespan for the
schedule. We study the structural properties of schedules which minimize the
makespan for a single job with attached setup times in a flow shop. The
structure of the optimal...
Do people choose an optimal response criterion in an inspection task?
Tập 30 - Trang 257-266 - 1998
In order to provide models of human behavior useful in selecting tradeoffs in
function allocation of inspection systems, an experiment was performed to test
five optimization models of the decision component of inspection tasks. Ten
subjects examined numbers printed on computer-generated Integrated Circuit (IC)
chips to decide whether to accept or reject the ICs under different conditions
of defec...
