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 1990 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any job, project, program, or complex undertaking there exists a need to understand all aspects of the work. This understanding is necessary to satisfy all requirements in the most effective and efficient way. The methods available to plan and accomplish these tasks are as vary as much as the tasks themselves. They range from job shop techniques to Material Requirements Planning (MRP) to Project-Based Management Information System (PBMS) to continuous manufacturing. This paper is a critical analysis aimed at classifying two of these system approaches as they relate to the ship repair equation. Material Requirements Planning (MRP I) tracks a need for material through a project. The production process on the material determines how labor is applied to transform raw materials into finished products. MRP material needs are determined by sales forecasting; while requirements are determined algorithmically from material take-offs. Another form is Manufacturing Resource Planning (MRP II). This form of MRP is a management process, supported by computers, which results in monthly production plans based outlooks, etc., and is far sales more comprehensive in scope and integration than MRP I.

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 1988 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Zone Logic Technology CAD/CAM and networked Database Management System is an integrated system of commercially available, off-the-shelf computer hardware and software products. These products have been carefully selected, tailored, and integrated to specifically satisfy and support the Philadelphia Naval Shipyard (PNSY) Zone Technology Program in support of work packaging development, computer aided graphics and an on line, real-time, distributive database management system. The process used publishing this paper serves as a small example of some of the capabilities of the system at PNSY. The entire document, including graphics, was generated on the system. Scanners, CAD and PC systems were utilized to input, develop and convert the graphics files into appropriate formats for import into a technical publications software package. LAN interconnection capabilities provided option developing portions of this document on different systems and at different locations with the ability IO access the appropriate files remotely. Philadelphia Naval Shipyard has thrust itself into the 21st century in both new management and automated technologies. Senior managers arc making bold business decisions necessary to the shipyard shipyard's survival. A pilot project has been initiated to develop and execute a transition phase to improve shipyard productivity. Major changes to management, workpackaging, production, planning, and design execution are currently ongoing Computer assistance has been developed and is being coupled with these changes, thus forming a Zone Logic Technology (ZLT) Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) and networked Data Base Management System (DBMS).

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 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 1981 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The over-riding concern in shipbuilding today is how to increase productivity. However, attention instead should be focused upon improving management policy. Quality of goods and services produced and the improvement of production operations from a controlled learning experience should be management's primary goals. By concentrating on these, increased productivity will be a by-product. The learning process, however, requires a basis from which management, can evaluate past performance and develop a program for avoiding failures and improving upon the successes. This basis does not evolve by happenstance. It must be the result of deliberate, careful and reasonably detailed planning and a means for capturing actual performance against the plan. This discussion addresses the vital need to consider and accommodate the impact of limited resources (manpower, floor space crane capacity, etc.) to the planning Problem. Often ignored by planning, resources, if not available in sufficient quantities, or not applied properly, will most definitely lead to higher costs and longer production schedules.

This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: NAVSEA Shipbuilding Support Office, Philadelphia, PA provides current Manufacturing Lead Time information to Navy planners, designers and acquisition managers responsible for the timely procurement of the latest design Navy ships. Lead time information is critical to effective budgeting and on-time delivery of basic material, hull mechanical and Electrical Components and Combat Systems. This paper will address the methodology for solicitation, statistical consolidation and final assessment of information provided by over 1300 domestic primary and secondary manufactures. Early detection of lead time change provides a basis for remedial action whereby critical paths may be selected, schedules altered, or substitutions provided. The paper will further address the status of the United States Industrial Base capacity to provide these materials, components and systems and compares the current industrial base with its status five and ten years ago. Loss of domestic capacity has resulted in sole or single source procurement and in some cases sole dependence upon a foreign source for critical subcomponents. The ability of United States manufacturers respond to peacetime programs and potential surge or mobilization requirements will also be examined.

This book was released on 1988 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Management in the United States often falls into the trap of invoking Theory Y programs in Theory X ways" Perhaps nothing conceptualizes the plight of American businesses implementing new programs and techniques quite as succinctly as the preceding statement. Many of the buzz words of celebrated methods and techniques used in Japan have been popularized in the U.S. Unfortunately, the implementation of these techniques is not given the careful consideration it demands. Although participative management did not achieve full potential in the U.S. with the introduction of quality circles, the foundation was laid and lessons were learned. The organization and operation of a company needs to be considered for a successful implementation. System Strategy Teams represent an adaptation of participative management developed specifically to function within Peterson Builders.

This book was released on 1985 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to address the problems inherent in a trade oriented production organization, and to develop a work force which will perform efficiently and effectively in a zone construction environment, NASSCO bas proposed to develop semiautonomous, multi-skilled work teams. The teams will be made up of a stable membership, be well trained, have multiple skills, and will have some degree of control over decisions necessary to complete work in their areas. One supervisor, rather than individual trade supervisors will be responsible for completion of work within the area. Employee participation will be encouraged to the greatest possible extent. Although ultimate authority for decisions within the work area will remain with the supervisor, it is envisioned that the traditional role of supervision will shift in emphasis from boss to facilitator acting as liaison between the work team and other parts of the organization.

This book was released on 1985 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management has been defined as the universal process of accomplishing work through others. It consists of handling and making decisions on many conflicting requirements at the same time. Because of this, management analysts try to eliminate the complexity by conveniently dividing it up into functions and then discuss each function and the relationships between them. The four functions that are always listed are: Planning, Organizing, Directing, and Controlling.
