Development Of A Knowledge-Based System For Human Error Analysis, Bang-Chiang Sung

Theses

Human Factors is one of several essential issues in a discussion of system productivity. Its consideration must be included in the design, development, operation, and maintenance of any human-machine system. In order to maximize the system productivity, humans must perform with their maximum possible efficiency. To achieve this, all human-related activities must be evaluated to determine their possible causes of errors and the consequences. Then, if unable to completely remove, the causes of human errors must be minimized.

This thesis integrates a knowledge of expert system into an analysis of human errors. Its objective is to develop a knowledge-based system …

Utilization Of The Theory Of Constraints Approach For Improving A Manufacturing Enterprise Profitability : A Case Study, Yaron Chaut

Theses

The past two decades have been a difficult period for the U.S. as it lost its dominant position in one manufacturing industry after another to Japan. The American worker was initially blamed for this phenomenon - he was too expensive, was less productive, and produced lower quality products then the Japanese worker. The opening of factories in the U.S. managed by Japanese with American workers proved this claim to be wrong, as their products were competitive and often even better then the original Japanese products. It also indicated that the Japanese production planning and control methods are the primary reason …

A Methodology For Evaluating Prospective Investments In Flexible Automation, Werner A. Eikenbusch

Theses

The flexible automation of production systems (FA) provides the technology necessary for competitive success. However, the use of traditional budgeting methods has proved unsatisfactory when evaluating this type of investment, primarily because of the inadequate consideration being given to the resultant strategic benefits.

A methodology considered suitable for evaluating FA investments is proposed together with an illustrative application. To determine its industrial usefulness, manufacturing managers of North American and West German companies were surveyed both via interviews and via questionnaires. Their response confirms the merit of the procedure, despite the differences in competitive foci found between the American and the …

The Evaluation Of Efficiency Determination Of Screening Device (Pressure Screen) By Image Analysis, Rajeev Kumar Goyal

Masters Theses

The Omnicon 3600 image analyzer was used in the study of the evaluation of screening efficiency determination methods. It is very difficult to get a good over all contaminant mass balance across a pressure screen because of the factors involved such as sampling around a screen, time spent in collecting the samples, and possible size reduction of the contaminants by the pump and screen. The image analyzer gives the contaminant analysis in terms of the total number of particles, total area of all the particles, the mean particle area and a histogram of the contaminant size distribution. The histogram data …

Proposed Scheduling Methods For Printed Circuit Board Assembly, Tali Freed, Ezey M. Dar-El, Oded Z. Maimon

Industrial and Manufacturing Engineering

The current practice in the assembly of electronic components on printed circuit boards (PCB's) is serial production, a process characterized by very long set-up times.

However. with the advent of efficient on-line process information, new production control methods are now possible. This paper proposes two new production methods - the Grouped Set-up (GSU) method and the Sequence-Dependent Scheduling (SDS) method, which can significantly reduce set-up times.

It is shown that the GSU always performs better than the SDS method in terms of total production flow (throughput). while the SDS performs better than the GSU method in terms of work-in-process (WIP) …

Learning Curve Model For Interrupted Production, Behzad Zarkoob

Retrospective Theses and Dissertations

Traditionally the learning curve technique has been applied to the case of continuous production. In such cases the cost par unit declines by a constant or staged percentage due to the learning phenomenon. Although this technique has been an important management tool to predict cost and productivity, there are other factors that wil~ affect the learning curves and its forecasts. One of these factors is "forgetfulness," which is caused by program interruptions for a significant period of time. It is expected that due to the interruption a relearning process may have to take place. The objective of this report is …

Efficient Algorithms For The Fixed Charge Problem, Ahmad Abdulah Moreb

Retrospective Theses and Dissertations

The main thrust of this research is to develop four solution procedures for the Fixed Charge Problem. All are based on approximating the fixed charge component by strictly polygonal linear components. The first procedure uses the functions technique to approximate the fixed charge; then linear programming with the restricted-basisentry technique is used to arrive at the final solution. Although this method starts with an approximated version of the fixed charge component, it arrives at an exact value to the objective function without the need for re-evaluating the objective function. The other three solution procedures are based on approximating the fixed …

Economic Design Of Lot-By-Lot Acceptance Sampling By Attributes, Michael S. Wall

Retrospective Theses and Dissertations

Risk-based sampling plans have long been the accepted standards in the practice of acceptance sampling for quality control. Usually the economic consequences of a given sampling plan are assessed by experience and intuition at best. With the availability of high speed computers and well-proven statistical methods, economically-optimal sampling pl a ns can now be developed so that much of the guesswork is removed. This study first surveys these methods for deriving economically-optimal sampling plans. Then, recognizing the reluctance in government and industry to abandoning ris k-based design of sampling plans, a method is explored which poses a compromise between the …
