Scheduling Models

Model 1: The Simple Model. Suppose a manual scheduler has a certain probability of scheduling an employee's day correctly. Further, suppose that the scheduler completes each attempted schedule. If the attempted schedule is invalid, the scheduler begins another attempt at completing a valid schedule. There is an interactive script to illustrate this model.

Model 2. Suppose that after creating an invalid schedule, the scheduler returns to the position in the schedule at which the mistake was made, corrects the error, and continues.

Model 3. Scheduling an employee's day is considered successful if the scheduler then decides to continue rather than to restart the schedule creation process. The Scheduling Model 3 JavaScript estimates the time required to manually create a schedule for a given number of employees over a given number of weeks. The Total Time Cost of Manual Scheduling script calculates the total time cost of manual scheduling (including staffing and maintenance) using Model 3.


For more detail, see The return on investment of computerized scheduling and staffing, which is a PDF document. If you are unable to view PDF, you should go to the Adobe Acrobat Reader download page. Alternatively, you can download a Maple version, but this is probably only useful to those with version 5 or better of the Maple mathematics package.

Two other pages on this site are A comparison of real option valuation with traditional methods and a summary of "Marketing automation meets the capital budgeting wall". These two pages are cover the problems of valuing information technology (such as scheduling systems). If you wish, you can also see the resume, transcript, or home page of the author of these pages.
