Gerber Project For Lockheed Martin, Andrew Callahan, Sean Lawyer
Gerber Project For Lockheed Martin, Andrew Callahan, Sean Lawyer
Industrial Technology and Packaging
Lockheed Martin, the world’s premier aerial combat vehicle manufacturer was pressed to find an eco-friendly way to package their impregnated epoxy. In the current system, the epoxy would be cut on the Gerber table to a pre-determined length and then sandwiched inside of two corrugated fiberboard sheets for storage inside of a freezer. The current process was not only labor intensive, but the corrugated fiberboard had to be disregarded after one use. In conjunction with the Cal Poly San Luis Obispo Packaging program and Melmat Incorporated, we were able to find a corrugated plastic substrate to replace the currently non-reusable …
A Computer-Based Economic Analysis For Manufacturing Process Selection, Manocher Djassemi
A Computer-Based Economic Analysis For Manufacturing Process Selection, Manocher Djassemi
Industrial Technology and Packaging
An important part of financial planning in product development is considering whether the capital expenditures meet volume and cost goals. A good business plan should provide investors with the implications of process selection on the company's bottom line. It is estimated that there are least 1000 manufacturing processes and sub-processes. Considering the number of process choices and quantity of cost data, an economic analysis for process selection may pose a challenge for decision makers. This paper provides an insight to Ashby’s cost modeling method for generating an estimate of unit product cost. The cost model provides a broad indicator for …
Merits Of The Production Volume Based Similarity Coefficient In Machine Cell Formation, Hamid Seifoddini, Manocher Djassemi
Merits Of The Production Volume Based Similarity Coefficient In Machine Cell Formation, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
In this paper, two types of similarity coefficients are compared: (1) the Jaccard's coefficient and (2) the production volume based coefficient. Each is used to form a cellular manufacturing system whose performance will be used as a measure of effectiveness of the similarity coefficient. The sum of intercellular and intracellular material handling costs is used as a criterion for performance evaluation.
Analysis Of Efficiency Measures For Block Diagonal Machine-Component Charts, Hamid Seifoddini, Manocher Djassemi
Analysis Of Efficiency Measures For Block Diagonal Machine-Component Charts, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
Group efficiency measures have been developed to evaluate machine-component charts for the formation of cellular manufacturing systems. In this paper the existing grouping efficiency measures will be evaluated by determining the relationship between the values of a grouping efficiency measure and the performance of the corresponding cellular manufacturing system.
A Dynamic Part Assignment Procedure In Machine Cell Formation, Hamid Seifoddini, Manocher Djassemi
A Dynamic Part Assignment Procedure In Machine Cell Formation, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
A major contributing factor to the under utilization of machines in cellular manufacturing is the development of long queues in front of some machines in machine cells. This paper presents a procedure which identifies such machines and redistributes their loads to alternative machines whenever feasible.
The Production Data-Based Similarity Coefficient Versus Jaccard's Similarity Coefficient, Hamid Seifoddini, Manocher Djassemi
The Production Data-Based Similarity Coefficient Versus Jaccard's Similarity Coefficient, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
This paper compares the performance of Jaccard's similarity coefficient with the production data-based similarity coefficient. A number of machine-component charts taken from the literature or randomly generated are used to form machine-component groups. Then, the sum of intercellular and intracellular material handling costs for each machine-component group is calculated and used as a basis for performance evaluation of the two similarity coefficients.
