A data tree structure for a hierarchical structure processing

1994, Computers & Industrial Engineering

Abstract

In this electronic age, the manufacturing sector has been searching for a unique data structure scheme which can easily represent different data types relating to design, process and inventory management. In this paper, an efficient way of representing the hierarchically significant data, especially in manufacturing, is investigated. Unlike the contemporary tree structure representation using pointers, this approach adopts a unique arithmetic encoding scheme to represent individual paths. The encoded nodes will have the capability to regenerate the entire paths (of a tree) using simple arithmetic procedures. The most significant benefits of this approach are increased data processing efficiency and ease of navigation of data paths in hierarchical data structures. The preliminary testing of this approach on a simulated factory data have indicated significant improvement on data representation and processing efficiency. This structure promises application in Computer Aided Design, Manufacturing Resources Planning, and Hypermedia Data Structure.

Key takeaways

  • The Item Master File (IMF) is an an indexed file and includes one record for each end item, assembly, subassembly, piece, part, and raw material.
  • In order to implement the HSPN approach, all real end items are made assemblies of a pseudo end item.
  • Two of them have the item numbers '333333' and the other two have the item numbers as ' 1111111'.
  • Tables 7 and 8 show the performance results of the inverted HSPN approach for the explosion and implosion queries on product structure of the simulated factory, Fig. 6.
  • The remainder (2/19) is the encoded number of the next higher item in the bill (Clamp Assembly).
