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...
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...
The development and evaluation of CUSUM-based control charts for an AR(1) process
Tập 30 - Trang 525-534 - 1998
An important component of the quality program of many manufacturing operations
is the use of control chart for variables. Inherent in the construction of these
control charts is the assumption that the sampled process is a normal
distribution whose observations are independent and identically distributed
(iid). Many processes such as those found in chemical manufacturing, refinery
operations, smel...
On combinatorial auction and Lagrangean relaxation for distributed resource scheduling
Tập 31 - Trang 813-826 - 1999
Most existing methods for scheduling are based on centralized or hierarchical
decision making using monolithic models. In this study, we investigate a new
method based on a distributed and locally autonomous decision structure using
the notion of combinatorial auction. In combinatorial auction the bidders demand
a combination of dependent objects with a single bid. We show that not only can
we use...
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...
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 non-interfering selective disassembly sequence for components with geometric constraints
Tập 34 - Trang 349-361 - 2002
This paper analyzes the problem of global disassembly of a selected component
from a geometrically constrained assembly. The geometric constraints are: (i)
spatial constraints due to the three-dimensional geometric interactions between
the components in an assembly; and (ii) user-defined constraints, such as
grouping of components as subassemblies and directional constraints on component
geometry....
