This book was released on 1976 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: For enhancement of the SPADES System, three new modules are currently planned and under development: 1) Ship Production and Control Module (SPAC) - A management information system which utilizes the information collected on the SPADES data base. 2) Detail Engineering Module (DEMO) - A module that is designed not only to produce engineering drawings, but to aid in data collection and consequent loading of the data base with information generated by the Engineering Department. 3) Pipe Length and End-Cuts Program (PLEC) - A special program to aid in fabrication of complex three-dimensional pipe structures, which is of special interest to manufacturers of oil rig structures. Like all other modules of SPADES, these new modules will directly access the SPADES data base, utilizing information that has been generated by other modules, and in turn making it. Thus, information is available to the other modules information gathered by collected and stored where it is generated. There will be no need to recreate information by other departments downstream with the duplication of effort and a high probability of errors. The three new modules will continue the expansion of SPADES from an Numerical Control manufacturing method to a computer-controlled information flow throughout the entire design and construction period.

This book was released on 1977 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major shipyards that utilize SPADES and Call and Associates have organized a user group. Annual two-day SPADES user meetings are held in danuary of each year to discuss problems and improvements to the system. The SPADES steering committee meets just after the user meeting and again in dune (in conjunction with the REAPS meeting) to make official decisions on problems improvements or changes. At these sessions, priorities for Call and Associates to work toward are established. A problem identification form and a suggestion and improvement form were designed and adopted with a procedure for informing Call and Associates and all SPADES users about changes or problems within the system. Call and Associates assigns a unique identification number to these forms and submits comments. The Steering Committee serves as a catalyst to Call and Associates for constant improvement of the SPADES System.

This book was released on 1976 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the decision was made to proceed with the development of the Interactive Graphics version of the SPADES System, a list of requirements and goals was made. One of the major considerations was to have total interchangeability between the graphic and the batch mode of the System such that rework could be processed easily, whether the original work had been done through the 'CRT' or in batch. As much as we would like to think otherwise, experience has taught us that changes and revisions are an ever present way of life during the ship design and construction process. The requirement was also set that none of the SPADES management and control features would be compromised because of the graphic. In order for the graphic version to be a useful production tool, the user would have the capability of totally checking parts and/or burning tapes generated through the CRT without having to wait for a drafting machine drawing and/or computer printout. It was also decided that the user would have the capability of switching from one program to another directly from the tube without re-initializing any program at the central computer. The plans called for four CRTs to be on simultaneously, and for at least one batch SPADES program to be also running at the same time. This requirement caused the only major modification of the then existing SPADES System in order to allow different programs to read and write records from the same data base at the same time. By combining the use of virtual memory capability of the computer and judicious use of overlay, all the applicable programs have been linked together in one executable module.

This book was released on 1976 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the National Steel and Shipbuilding Company (NASSCO) set out to use SPADES, an internal company organization for its use emerged, resulting in an effective working relationship among the various departments of the company. These departments are Engineering, Production, and Computer Services. The NASSCO organization for SPADES evolved along regular functional lines within the departments affected. Loftsmen, who used to make full size wooden templates on the mold loft floor, are now the Numerical Control (N/C) programmers who cause the N/C tapes to be made. Engineers, who issue preliminary unfaired ships lines, are now able to complete the job, since the fairing operation does not require a drafting board the size of the mold loft floor. Computer service personnel, who run the company computer, have added SPADES to the services they provide. And finally, the responsibility for control of the SPADES system is assigned to the Computer Support Group in the Engineering Department, which has charge of all scientific and engineering programs used by the Engineering Department. The user functions are divided between engineering and production. There are eight SPADES modules, three of which are used by the Engineering Department, three used by the Mold Loft, and two used jointly or by either as needed. The three engineering modules are: the Fairing and Drawing module; the Hulload module; and the Hullcal module, which is a package of naval architecture routines. The three modules used by the Mold Loft are: Part Generation module, which produces information and a tape for drawing the part; Nesting module, which produces a tape of nested parts for the burning machine; and Plate Development module, which produces tapes for burning shell plates. The Manufacturing Aids module is used jointly by Production and Engineering. Another joint-use module is the Utility module. This is a group of five programs used for direct access to the data base.

This book was released on 1976 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: SPARDIS provides NASSCO with a tool to use one of its most valuable resources - information. SPARDIS is designed to provide various levels of management with the information they need to better perform their function. It is intended that the task of providing this information be accomplished with the least amount of paper work. To do this, all of the SPARDIS information is in the form of on-line, real time, data inquiry and update. Data is collected, updated and maintained for the system through a network of communications terminals. These terminals are located where data is originated, the system user area. The communications terminals are located throughout the shipyard at strategic locations for both inquiry and update. Responsibility for data input is placed in the area organizationally responsible for its creation and maintenance. The teleprocessing system permits decisions to be made based on the latest information available. As a management tool for planning and scheduling SPARDIS provides: .Explicit Schedule and instructions to make parts, assemble components install. equipment, etc.

This book was released on 1977 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: With shipbuilding capacity worldwide well in excess of demand and competition for orders extremely fierce, shipyards must ensure that all resources are used effectively. Each man on the shop floor, each foreman and manager must be able to carry out the work required of him - which means that he must be provided with all the required information on the work to be done and the means to carry it out. The competition for orders, quite apart from resulting in shorter lead times, has resulted in shipyards building a wider range of products than was envisaged even a short time ago. The potential. variety of individual operations within a shipyard in this situation is much higher than in the case of a single product facility. The information channels used in this production system are similarly going to require greater capacity, speed and accuracy. SPCS is a flexible and uncomplicated approach to production control, aiming to supplement management rather than to replace management decision making by black-box decision rules. It consists of a set of inter-tied modules, each of which is executed either manually or by batch computer processing or on-line, depending on local circumstances.

This book was released on 1981 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the growth of a shipbuilding concern, a time arrives when manual efforts to control cost and report status become undesirable. However, when an attempt is made to apply readily available software, many obstacles are presented. One approach to avoid many of these obstacles is addressed. By describing vessel construction through a network of dated work orders, and the treating of this network as a structured bill of material, standard software packages can be used to manipulate the data necessary to provide material requirements planning and job cost accounting. Critical issues impacting the selection and successful implementation of computerized systems are also discussed.
