Optimally Scheduling Resource Constraint Project Using SAS/OR®
Jeff Cai · 2010
This paper shares with SAS users an approach to effectively distribute programming resources in a clinical study project or among several projects by using procedures and macros in SAS/OR®. Considering some activities in a project may have precedence and time constraints, and each programmer may also have different time constraints, such as different start date and quit date on a project, personal vacation, etc., one effective method is to use constraint programming procedure CLP to optimally schedule these activities for project management. By incorporating a specific calendar, user can estimate the project target date with the constraint resource, or forecast the required programming resource with the constraint target date. Plot procedures NETDRAW and GANTT for visualizing activity data are described in this paper as well.
