2116982 9305476 PCTABS00020 A method which applies the critical path method to repetitive tasks having constant rates of production allows a user to plan a schedule and to track progress of repetitive tasks for large and complex jobs, with minimal data entry, and which is updatable to reflect actual job progress. Data for a template unit is transformed into a critical path method (CPM) network for an entire job by determining repetitive tasks (2) with their respective durations and precedence relationships for each additional unit in the job.. Precedence relationships between same tasks but different units are also considered (1100-1145). These latter precedence relationships take into account the movement of crews through units and/or the movement of units through work stations. Special constraints may be incorporated into the network in order to provide continuous work for the crews (1201-1213). The CPM network is used to calculate earliest and latest possible starting and finishing dates for each task performed on each unit (6). The planning schedule is produced in a concise, easily-interpreted format which is an improvement over traditional Gantt bar charts (7).
