This book was released on 1982 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1982 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the premise of engineering standards, Standard planning Modules represent production work package arrangements which are predefined to simplify the creation of planning networks at the central planning level. The approach centers around the notion that a vast majority of production activities can be established without the aid of available, detailed engineering. The creation of workpackages under this approach is dependent solely upon historical production performance, adaptation of work from previous vessels of the same class, specific details provided by the vessel's specification, and general arrangement engineering drawings. Final production schedules, at the workpackage level, become a derivative of the planning schedule as detailed information becomes available from engineering, material procurement, and other sources. The nature of planning a ship's construction has historically dictated that most, if not all, of the ship's details be known. Working from production drawings, Planning generates the varied labor workpackages necessary to support the fabrication and installation of steel and systems, Since Planning waits for such detail to be available, the timing of the production schedule development tends to occur immediately before those schedules are needed by the yard. In fact, a common complaint of many shipyards is that the production schedules are often published after preliminary construction has begun, normally in the form of steel cutting and substructure assemblies.

This book was released on 1979 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the REAPS Technical Symposium. Paper No. 24: Group Technology and Automated Process Planning, a Change in Management Strategy. The trend toward increased customization is increasing the problems associated with batch manufacturing, both in design and manufacturing itself. Group technology helps to solve these problems and is thus attracting great interest. The benefits of group technology in such applications as design retrieval, design standardization, standardization of machine tool routings, automated process planning, and machine tool investment can bring about dramatic savings in the multibillion dollar manufacturing industry. Three or four years ago, only a handful of companies were interested in group technology. Today, many companies, including a number considered to be highly conservative, are seriously considering or have adopted group technology systems. This increased interest is a reflection of a growing awareness of the potential benefits of group technology, particularly for batch manufacturing. These advantages can apply to both design and manufacturing.

This book was released on 1982 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: American shipbuilding management and planning has become a topic of increasing discussion in recent years and various proposals for change have been advanced. Many of these propose adoption-of certain techniques and approaches successfully used --in other major shipbuilding countries such as Japan and Korea, where shipbuilding management is based on organizational, decision making, and operating structures and procedures founded on quite different cultural backgrounds, human relations, and traditions than those found in the U.S. While some of the techniques and approaches found successful in those countries may be transferrable, it must be recognized that the environment in the U.S. cannot be changed in the short run. This makes successful application of some of these methods difficult. Factors which make Japanese and Korean shipbuilding competitive include value engineering, quality circles, labor incentives, high productivity manufacturing processes; rationalized ship design and production, effective organization, labor relations and flexibility, good supplier and customer relations, and effective production planning management and control. There are some factors which are distinctly different, such as the lack of adversity between shipbuilder and client on one hand and management and labor on the other hand. There is a general recognition and acceptance in these countries that adversary relations and potential litigous actions hinder achievement of ship production efficiency and on schedule low cost (and therefore price) delivery. Similarly most supplier, client, and labor issues with shipbuilding management are resolved by various informal approaches with little if any delay. This is quite different from the generally formal approach used in the U.S.A., where procedure, documentation, and even conflict resolution methods are often defined.

This book was released on 1982 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past year and a half, five participating shipyards have been preparing labor time standards using MOST Computer Systems on a time sharing basis. The result has been the development of separate databases covering the following operating areas: blast and paint--platen and dock areas; Electrical--shop and outfitting; main assembly; fabrication shop; and staging erection and teardown--platen, dock and ways. The ability to transfer data from one yard to another is discussed, as well as the methodology for such transfer. The actual use of transferred data and its application is covered to the extent that it has occurred up to the date of the symposium.

This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper addresses the key functions of a closed-loop production and inventory, and planning control system generally applicable to the shipbuilding industry. A key feature of the shipbuilding closed-loop system is the application of made-to-order concepts not generally used in production and inventory planning, and control systems for other industries. The use of modular packaged software to make the system operational on a timely step-by-step basis are explored. Special considerations for tailoring the software to satisfy general shipbuilding requirements are reviewed. A summary of the potential benefits of a closed-loop system (i.e., "what if" planning) is also included.

This book was released on 1977 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: WORK-PAC, Work Planning and Control System, is a complete computer software package designed to improve shipyard labor planning and to monitor labor charges against planned estimates, measure job progress and give notice to both real and potential labor over-runs and schedule slippages. WORK-PAC permits a ship repair/conversion or new construction project to be broken down into discrete work orders, which can be classified under any given set of work cost account categories: steel work; piping, electrical and machinery systems; outfit; design/drawing; and yard support services. To further facilitate labor scheduling and control, WORK-PAC allows these work orders to be assignable to specific ship zones and shop work centers. The input of planned manhours (with or without trade estimate detail) and scheduled start and finish dates and the actual manhours from timecards as applied to these work orders completes the planning feedback cycle that is tailored to shipyard operations. WORK-PAC accumulates labor charges by individual trade, differentiating between regular and premium manhours. In addition, a special WORK-PAC feature provides for separate accounting of job repair end re-work efforts as required. WORK-PAC generates numerous reports and analyses for various. levels of the shipyard organization and at various levels of detail. WORK-PAC issues automatic warnings of data errors and signals areas of budget over-runs and/or schedule slippages early in the production cycle before they become critical and while they are still resolvable.

This book was released on 1993 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large manufacturing industries have been able to successfully reduce cost and cycle time through the use of Manufacturing Resource Planning (MRP II) systems and principles to control material flow and the production process. Ship construction can not be neatly classified as a manufacturing process. The complex relationships involved with the installation and activation of ship's systems more closely resembles a construction operation. Work of this type has traditionally been controlled through an activity based network scheduling system. However, MRP 11 principles offer numerous benefits for the shipbuilding industry. This paper discusses an approach to planning, scheduling, and management of ship construction which takes advantage of benefits from both approaches. By using both network scheduling and MRP II in an integrated scheduling system, a shipyard will be better able to plan and execute the ship construction process.

This book was released on 1980 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1976 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of this discussion is to introduce a new version of the REAPS Program. In 1971 a Maritime Administration (MarAd) Advisory Group recognized a void in the area of computer aided shipbuilding. In response, MarAd acquired rights to the AUTOKON-71 system, the most widely used system in Europe. MarAd and the participating shipyards recognized the need to provide maintenance and support for the AUTOKON system. That effort was sponsored and paid for jointly by the industrial users and the government. It soon became apparent to all concerned that there was much more to be gained from computer applications in the shipyard than just running the AUTOKON system. A total shipyard program for computer automation beyond AUTOKON was needed. It was this decision that gave birth to the Research and Engineering for Automation and Productivity in Shipbuilding (REAPS) program; a joint participation program involving five shipyards, MarAd, and IITRI. Its purpose was to identify and address common problems in ship construction. The advantages were obvious. Participants could pool both the technological know how in identifying and solving problems and their resources to solve a common problem only once not repetitively at every shipyard. The REAPS program, a new concept in cooperative developments among several shipyards, was working. One thing began to change--the objectives of our development projects. Originally, they were oriented to a specific computer system, AUTOKON; now they were becoming non-system oriented, standalone modules with no relationship to a specific computer system or software package. A new concept was needed. The "new" REAPS program as it has evolved to date is a non-systems oriented program with the separation of all AUTOKON related activities. The overall concept of the new REAPS Program consists of five basic elements: Advance Planning, Technology Assessment, Development Program, Technology Information Services and Discretionary Development.

This book was released on 1982 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
