Book Description
The use of computers to improve the productivity of U.S. shipyards has never been as successful as hoped for by the designers. Many applications were simply the conversion of an existing process to a computerized process. The manufacturing data base required for the successful application of Computer Aided Process Planning (CAPP) to the shipyard environment requires a "back to basics" approach. An approach that can lead to control of the processes occurring in the fabrication and assembly shops of a shipyard. The manufacturing data base will not provide management feedback designed for the financial segment of the shipyard (although it can be converted to be fully applicable) it provides "real time" manufacturing data that the shop floor manager can utilize in his day to day decisions - not historical data on how his shop did last week or last month. The computer is only a tool to be used to organize the mountains of manufacturing data into useful information for today's shop manager on a "real time" basis. The use of group technology to collect similar products, the use of parameters to clearly identify work content, the use of real time efficiency rates to project capacity and realistic schedules and the use of bar codes to input "real time" data are all tools that are part of the process. Tools for the shop floor manager of tomorrow.

Book Description
One of the key elements of the 1930's concept of Group Technology (OT) is the classification of individual parts into families of parts with similar attributes. Prior to the advent of zone construction in ship- building similar products, such as franes, floors and shell plates, were presented on separate drawings, which resulted in the grouping of similar materials on each drawing. The assembly process followed a similar logical pattern using each of the drawings in each stage of construction. The introduction of zone construction has applied these OT concepts to the unit assembly process. Computer Aided Process Planning (CAPP) and its requirement to organize manufacturing data in a logical, structured manner has brought the shipbuilding industry back to the GT concept in the structural fabrication shop . The subdivision of a ship into manageable subsets of interim products allows for the further grouping of interim products into families requiring similar manufacturing processes.

Book Description
Computer assisted process planning can be a first step toward the integrated use of computers in the design and manufacturing process to improve productivity in batch manufacturing. The key to the process of integration is a part feature recognition method to analyze and retrieve manufacturing processes and arrive at least-cost designs consistently linked to "best" manufacturing processes. Major problems are incompatible computers, software; and people.

Book Description
The planning environment in American shipyards has undergone a change[of technique and attitude with the upswing in use of computers. Traditional planning mechanisms have given way to PERT networks and sophisticated data collection and reporting computer systems. This transition has not been as successful as was intended as evidenced by the planning and scheduling problems faced by many of these computerized yards. Data processing was moved from the basic accounting arena into operations research and massive production-oriented systems which has diluted the planning effort. This is caused by planners which have not evolved from production, a planning attitude that the computer can solve all problems. and management's inability to recognize the shortcomings of computer software. Technology is available to assist the shipyard with total planning and complete ship's plans and schedules. However planning. in itself, must be adapted to use this computer technology and not be driven by it.
