| Title: |
XOPPS - OEL PROJECT PLANNER/SCHEDULER TOOL
|
| Author(s): |
Mulnix, C. L.
|
| Abstract: |
XOPPS is a window-based graphics tool for scheduling and project planning that provides easy and fast on-screen WYSIWYG editing capabilities. It has a canvas area which displays the full image of the schedule being edited. The canvas contains a header area for text and a schedule area for plotting graphic representations of milestone objects in a flexible timeline. XOPPS is object-oriented, but it is unique in its capability for creating objects that have date attributes. Each object on the screen can be treated as a unit for moving, editing, etc. There is a mouse interface for simple control of pointer location. The user can position objects to pixel resolution, but objects with an associated date are positioned automatically in their correct timeline position in the schedule area. The schedule area has horizontal lines across the page with capabilities for multiple pages and for editing the number of lines per page and the line grid. The text on a line can be edited and a line can be moved with all objects on the line moving with it. The timeline display can be edited to plot any time period in a variety of formats from Fiscal year to Calendar Year and days to years. Text objects and image objects (rasterfiles and icons) can be created for placement anywhere on the page. Milestone event objects with a single associated date (and optional text and milestone symbol) and activity objects with start and end dates (and an optional completion date) have unique editing panels for entering data. A representation for schedule slips is also provided with the capability to automatically convert a milestone event to a slip. A milestone schedule on another computer can be saved to an ASCII file to be read by XOPPS. The program can print a schedule to a PostScript file. Dependencies between objects can also be displayed on the chart through the use of precedence lines. This program is not intended to replace a commercial scheduling/project management program. Because XOPPS has an ASCII file interface it can be used in conjunction with a project management tool to produce schedules with a quality appearance. XOPPS is written in C-language for Sun series workstations running SunOS. This package requires MIT's X Window System, Version 11 Revision 4, with OSF/Motif 1.1. A sample executable is included. XOPPS requires 375K main memory and 1.5Mb free disk space for execution. The standard distribution medium is a .25 inch streaming magnetic tape cartridge in UNIX tar format. XOPPS was developed in 1992, based on the Sunview version of OPPS (NPO-18439) developed in 1990. It is a copyrighted work with all copyright vested in NASA.
