Network Scheduling of Shipyard Production, Engineering, and Material Procurement
Abstract
My role here is to present the rationale behind the shipyard's recent decision to upgrade its N/C burning facilities and develop inhouse programming capabilities. Credits for developing and implementing the proposed changes belong to Jim Wilson in the Engineering Department at Marinette Marine Corporation (MMC) and Filippo Cali of Cali and Associates (Cali) who spent many hours researching the alternative ways of generating and transmitting N/C images for shipyard use. In addition, Russel Morgan and Douglas Gifford of the Linde Division of Union Carbide as well as Duane Holloway of Calcomp must be recognized for their active support to provide the necessary software and hardware against a tight schedule once a "GO" decision was made.In order to present the technical side of Marinette Marine's Installation, I think it is proper to review the past events that led to it. It was in 1976 that Cali & Associates developed, jointly with Avondale Shipyards, the interactive graphics version of the Spades System. A paper on the subject was presented and a movie shown at the 1976 Reaps Symposium. While this software has been used successfully by Avondale, the requirement of a large IBM/370 Main Frame and expensive IBM 2250 CRT's has prevented us to use it in the course of our N/C service work or to make it available to any other Spades user. During the fall of 1978 we started looking for alternatives that would allow us to continue Interactive Graphics Development and not require a large capital investment in hardware. The present I/G version of Spades includes: Part generation; Nesting; Shell Development; Data Base access and display. It is our intention to further improve the nesting by combining with it an automatic nesting capability utilizing the Bill of Material, Modules Breakdown and N/C information collected by the "SPAC" (Shipbuilding Production and Control) module of Spades.
