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......
Computer-aided optimization of multi-pass turning operations for continuous forms on CNC lathes
Tập 31 - Trang 583-596 - 1999
The Computer Numerical Control (CNC) machine is one of the most effective production facilities used in manufacturing industry. Determining the optimal machining parameters is essential in the machining process planning since the machining parameters significantly affect production cost and quality of machined parts. Previous studies involving machining optimization of turning operations concentra......
Performance comparison between on-line sensors and control charts in manufacturing process monitoring
- 1999
The rapid evolution of sensor technology, using techniques such as lasers, machine vision and pattern recognition, provides the potential to greatly improve the Statistical Process Control (SPC) method for monitoring manufacturing processes. This paper studies the method of using on-line sensors to monitor manufacturing processes and compares that method with the control chart method, a widely use......
Spare parts management for technical systems: resupply of spare parts under limited budgets
- 2000
In this paper, we study the operational availability of a complex technical system consisting of several components. The components are subject to breakdowns, and hence for each component a limited number of spare parts are held in stock. If a system's component fails and it can not be replaced immediately, due to a lack of spares, the system becomes unavailable until a new component is installed.......
Incorporating Physical Demand Criteria into Assembly Line Balancing
Tập 33 - Trang 875-887 - 2001
Many assembly line balancing algorithms consider only task precedence and duration when minimizing cycle time. However, disregarding the physical demands of these tasks may contribute to the development of work-related musculoskeletal disorders in the assembly line workers. Three line balancing heuristics that incorporate physical demand criteria were developed to solve the problem of finding asse......
The dynamic T 2 chart for monitoring feedback-controlled processes
Tập 34 - Trang 1043-1053 - 2002
As manufacturing quality has become a decisive factor in global market competition, statistical quality techniques such as Statistical Process Control (SPC) are widely used in industry. With advances in information, sensing, and data collection technology, large volumes of data are routinely available in processes employing Automatic Process Control (APC) and Engineering Process Control (EPC). Alt......
On scheduling project activities with variable expenditure rates
- 1998
Commercial projects are undertaken with the expectation of maximizing financial returns. There are a variety of cash flow models in the literature in which payments, whose amounts depend on the type of contract quoted between the contractor and the client, are tied to the project events or to the completion times of activities. These models are of deterministic nature with respect to cash inflows,......
