LINEAR SCHEDULING AND VISUALIZATION

Abstract

There has been a resurgence of interest in linear scheduling as a practical and visual tool for use in planning transportation construction projects. Network analysis techniques and bar charts do not provide the planner with an adequate means of analyzing the way in which crews move through time and space. Linear schedules can be used to overcome this problem. A review of linear scheduling research is presented to show the need for a standard format that combines the best of prior research and experience. Recommendations covering this format and the methodology to be used in a proposed standard format are presented. Three basic symbols--bars, lines, and blocks--are developed for use in drawing linear schedules. Some thoughts on specialized linear scheduling nomenclature are provided. It is concluded that the process of drawing bars, lines, and blocks on a linear schedule places the primary focus on planning and returns a measure of credibility to scheduling.
