Image Theses and Dissertations An investigation of the effects of non-normal random elements on the distribution of the optimal solution function in a long-range capacity planning model The focal point of this thesis will be the production-distribution cost component of Long-Range Capacity Planning Model. This component is dependent upon the production level at the plants, the demand requirements at the demand centers, and the level of outside purchases required by the demand centers to fulfill their needs.

Image Theses and Dissertations The reliability of simple progressive dies The stamping process, of which the punching process is a major division, is one of the most important metal parts production methods in industry. Punching dies are the heart of the punching process. Die performance, as measured by the number of strokes between sharpenings and/or repairs, determines the important per part costs of die depletion and maintenance. Existing quantitative studies are principally on tool wear and punchability. View Item
Image Theses and Dissertations Determination of influencing factors for aggregate in-process inventory The intent of this thesis is to identify the variables within a manufacturing environment that significantly influences investment in aggregate in-process inventory. A discussion of how the significant variables interact to control investment is also considered. View Item
Image Theses and Dissertations A computational procedure for the solution of the single-stage production sequencing problem with deadline and earliest start time constraints A computational procedure for the solution of the single stage facility with deadline and earliest start time constraints is presented. The procedure is a modification to the Pierce and Hatfield algorithm for the solution of this type of problem. The aim of the procedure is to reduce the number of nodes that will require evaluation for an optimal solution and thus reduce the total processor running time required to produce this optimal solution.

Image Theses and Dissertations Truck fleet optimization within a system A thorough study of the Hercules quarrying system was made to provide basic information for recommending a truck fleet that would transport rock in the quarry with the intent of minimizing the rock system costs. View Item
Image Theses and Dissertations An experimental investigation of loading preference factors in a job shop The objective of this study was to investigate the effects of various methods of loading a job shop from a backlog of orders. View Item
Image Theses and Dissertations On the hypothesis that a direct correlation exists between methods changes and related productivity changes in non machine-controlled work situations This hypothesis: a direct correlation exists between methods changes and related productivity changes in non machine-controlled work situations, appeared to be at the root of many problems in applied work measurement. Therefore, the author decided to conduct an objective, quantitative analysis of its validity. View Item
Image Theses and Dissertations Make versus buy A rather contgroversial subject is tghe question of make versus buy, with regard to component parts or aeemblies. This thesis is directed at the problem of inding practical answers to the following question: Should a certain process or group of processes be performed by a comapny or by an outside vendor or manufacturer?

Image Theses and Dissertations The utility of information a method of evaluation The fundamental relationships among the design parameters of an information system and the utility of the information that a system produces are analyzed in an effort to develop a methodology for measuring the utility of information. The utility of the information is defined as a measure of the effectiveness with which the information can be employed to attain the objectives of the using organization. View Item
Image Theses and Dissertations The training and retraining of personnel The introduction of automated machinery in industry and the new technological advancements have caused the labor force to abandon their working areas due to the lack of skills. Although new equipment has created new jobs, the working force has not been prepared to undertake them. View Item
Image Theses and Dissertations Priority dispatching in a labor and machine limited production system This study considers the effect of priority dispatching in a labor and machine limited production system. A simulation model of an actual shop is developed using GASP II. The shop is characterized as a flow shop with cycling in which lots are subject to stochastic yields and reworks. Five labor sections, each operating on three shifts, exist in the shop. View Item
Image Theses and Dissertations An investigation into the output distributions of gert networks by the use of simulation The purpose of this research was to further the investigation into GERT output distributions. From the family of GERT networks containing only Exclusive-Or nodes, a generally applicable network form was chosen for simulation. A generalized computer program was written to simulate any specific network of this form. View Item
Image Theses and Dissertations Application of a simulator for short term forecasting in a high volume multi-product production line The solutions to the problems of production forecasting, scheduling, and in-process inventory control for high volume multi-product manufacturing lines are not readily available in current industrial literature. This study proposes simulation as a general approach to solving these problems and proceeds to develop a simulator which is applied to just such a high volume line. View Item
Image Theses and Dissertations Utility sub-systems in the building industry The building industry is perhaps the most fragmented large industrial complex in the country today. Consumers are expressing needs for faster delivery for more functional and sophisticated space at more reasonalble prices. At the same time, the industry in itself is faced with growing internal problems which are making it increasingly more difficult to perform even as well as in the past. This study investigates the area of utility sub-systems in the building industry. View Item

Image Theses and Dissertations An investigation of the relationship between manufacturing policies and plant layout in a job shop Utilizing CRAFT an optimum plant layout with regard to all products manufactured can be realized. In addition, two manufacturing policies; related to production and inventory control, will be investigated with respect to the effect of said policies on plant layout. View Item
Image Theses and Dissertations A Monte Carlo simulation of a materuak handling system The United States Steel Corporation referred us to one of their operating plants where the Chief Industrial Engineer wanted help in solving the problem of how many ingot buggies should they have. It was decided that the first of two steps should be 1) to completely understand the physical operation. 2) to collect what information was available. View Item
Image Theses and Dissertations On the computational efficiencies of the primal-dual algorithm and the uv-method for solving transportation problems Computational efficiencies of the primal-dual algorithm and the uv-method in solving transportation problems are compared in this thesis. A computer program was written in Fortran IV and run on the CDC 6400 system; it generated random problems with integer constants ranging in the size from 5X10 to 30 X 50, and solved them by both methods.

Image Theses and Dissertations Influences of demand patterns and capital expenditure programs on manufactured progress: a progress function approach The main objective of this study was to determine if the production effectiveness of a manufacturing organization is influenced by demand and/or capital spending. With regard to the overall objective this investigation examined the possibility of an organization experiencing different degrees of production effectiveness in conjunction with the deman pattern it faces.

Image Theses and Dissertations Quantification of intangible factors in product design decisions This paper concerns itself with quantification of the intangible factors in Product Design Decisions where there is one very big supplier with one very big customer and a unique product. The product design is represented as a state diagram, or curve, with Time as one axis and Product or Material State as the other. Industry affects the product design curve with various levels of decisions. This paper describes four of these levels and investigates a case in which three levels are involved. View Item
