Feasibility Study on the Design of a Computer System for Piping Layout Bills of Material.

Abstract

<p>A computer system has been designed to produce piping layout bills of material. Information from two major sources is required for the Bills of Material and the associated Isometric Drawing System. These two sources are the design specifications and design drawings. Design specification data is written and maintained, on a mass-storage device, as a master file. System input sheets are used to introduce the design drawing data to the -Isometric System which in turn stores such information on a massstorage device as a data file.</p> <p>The main computer programme of the Bills of Material System performs the following functions: (1) Retrieves the relevant data from the system input storage, based on the type of bill of material required. (2) Accumulates like items based on line service and on line size. (3) Matches and retrieves relevant specifications from storage. (4)Writes the bill of material. Bills of material of four types are possible in the designed system. These are: by bulk, by area (and sub-area), by line number, and by isometric drawing number. The bill of material may be printed on pre-printed forms. The flexibility of output and arrangement of data on a bill of material is a design characteristic of this system. Information flow charts and logic flow charts of the software developed for' the system are included. Complete documentation for the computer programmes developed, is submitted along with this thesis, as a "Detail Documentation Package".</p>
