A significant portion of shipyard steelwork can be mechanized through introduction of modern production line technology. The productivity improvements on such lines arise principally from more efficient material handling and a corresponding reduction of time lost between operations. Panel lines are undergoing exiting developments and are being installed even in very small shipyards. Efficient and affordable web line and beam line technology is now available but not yet adopted by shipyards in the United States.

The Institute for Research and Engineering for Automation and Productivity in Shipbuilding (IREAPS) is an organization which conducts an industry/government cooperative program for enhancing U.S. shipbuilding capabilities through development and implementation of improved systems and manufacturing technology. The primary thrust of the IREAPS program is the conduct of research and development projects for a variety of design and production processes in the shipyard. Such projects are initiated and pursued only upon consensus of the participating organizations and are not considered complete or successful until they have been implemented under actual shipyard production conditions.

Planning Research Corporation has been working with the U.S. Navy for the past 2 years in providing a unique production management system for Navy Intermediate Maintenance Activities (IMAs). This system, successfully adapted from commercially proved techniques and underpinned by engineered labor performance standards, is in use at the Shore Intermediate Maintenance Activities (SIMA) Norfolk, Virginia and Mayport, Florida. Additionally, implementation of the system is underway on an incremental basis at SIMA, San Diego, California. The engineered labor performance standards, developed as Engineered Time Values (E.T.V.), provide a means to accurately plan, schedule and progress work, to exercise production control on a real-time basis and to analyze factors affecting productivity in order to effect remedial action. A key feature of the Engineered Time Values (ETV) System is the Productivity Management Information Component (PMIC) which supports these functions through the use of interactive computer equipment. 197 In the planning function, ETV information resident in the PMIC is accessed by the assigned planner using a visual display terminal. The planner selects.

The authors describe the need for fully integrating all aspects of shipbuilding so that current resources can be utilized in the most effective and cost-efficient way possible. The integration of manpower, scheduling, and material control using mini-computer planning, and cost/ schedule control systems have proved to be extremely beneficial to small and medium sized shipyards. These systems have given management an added insight into areas that have been troublesome. Now, corrective action can be applied and the results measured quickly, directly, and accurately. By integrating all efforts of the shipyard plan, relative merits of new production techniques can be measured and evaluated. This extension of management visibility and control permits the shipyard to implement new technologies with far more confidence than possible before.

It can be taken as true that an organization which specializes in one area produces at lesser cost than an organization which, in one plant, produces and assembles in substantially different areas. Shipyards which manufacture and assemble many different products recognize the advantages of specialization; they try to purchase materials and equipment in as finished form as available for further assembly and installation. In some areas shipyards go further and subcontract the installation of material directly into ships. The thesis proposed here is that the productivity of U.S. shipyards would be increased and ships would cost less if a deliberate policy of extensive subcontracting of material and its installation labor within shipyards were adopted. In time, shipyard staff would become primarily specialized efficient organizations which coordinate the work of specialized, independent contractors. The organizations would be the same in principle as those which have developed for most large, land-based construction.

This paper addresses the problem of establishing meaningful work order labor budgets for use in a shipyard pipe fabrication shop. Two methods are described for developing planning or scheduling standards. The first builds upon an existing base of detailed fabrication labor standards, which may be engineered standards or measured standards. The second uses sampling and statistical analysis to develop the planning or scheduling standards in situations where there are no existing labor standards. The first approach was applied in a seven month pilot project sponsored by the Maritime Administration through the Ship Producability Research Program. The procedures and results of this pilot project are described. The primary result was a fifty percent increase in the perceived capacity of the shop, with no additional investment in equipment or labor.

Quality circles have been found to improve productivity an average of 12% in 3 to 6 months in a controlled research pilot study performed by Business Innovations, Inc. for the U.S. Department of the Navy. Human relations and job satisfaction were also found to improve within a few months of starting quality circles at four companies. Quality circles (QC's) have been adopted widely by U.S. and Japanese industry and are increasingly finding acceptance in U.S. industry, including shipbuilding. The average return on investment for quality circles is 6 to 1. QC's are a simple, but effective, technique for problem solving which involves employees and increases motivation, communication, and productivity. They are a phenomenon of group dynamics not quality control techniques. Implementation of quality circles needs to be carefully planned and should involve all levels of management and employees. An alternative to quality circles at foreman and management levels is "productivity teams". These involve more sophisticated training and the use of industrial engineering techniques. Productivity Panels and quality circles area low cost, high return investment for shipyards to cut costs and turn around companies with lagging sales due to decreased international competitiveness.

Private shipyards are under heavy pressure to improve productivity. So are the naval shipyards. Like the private shipyards, naval shipyards are focusing on improved production planning, scheduling, labor/progress data collection, and industrial engineering as the main thrust of their productivity improvement programs. Unlike the private shipyards, however, the naval shipyards are drawing heavily on the use of computers to support these functions. One project, the subject of this paper, is of particular interest since a computer is used to integrate planning, scheduling, work-in-process tracking and labor collection functions with engineered labor standards to provide a closed-loop production control system for a key production shop at the Portsmouth Naval Shipyard. This system achieved operational status during the spring of 1980. A complete economic history of its initial economic justification, development and operating costs and preliminary indications of payback are now available. Since the design of this system makes it quite appropriate for private shipyard use, the data included within this paper should be of interest to those concerned with the economics of computers in private shipyard production control functions. Results of this project are correlated with the objectives and results of the National Shipbuilding Research Program.

In 1960 B & W Shipyard commissioned new yard facilities introducing new building methods with large blocks (modules, sections) assembled in the building dock by gantry cranes. To ensure effective operation of such facilities, computer based sophisticated planning and control systems were developed. The anticipated improvements in production efficiency of the new system remained, however, for the first decade of operation as it was with traditional shipbuilding. Upon thorough analysis of the situation the yard management was forced to acknowledge that the excessive complexity of systems applied had made the understanding of fundamental parameters for successful planning and control of new systems ambiguous.
