The optimal size of a transit operating work force is based on the appropriate amount of overtime that can be requested of the work force. Overtime is typically used to fill in for absent operators if no extra operators are available to do the work on regular time. However, relying more heavily on overtime has two risks. First, no operator may be willing and available to work overtime when it is needed. This will result in missed service and hence poor service quality. Second, operators may be absent more often because they can readily obtain overtime work at a significant wage premium. These interrelationships between overtime, absence, and service reliability are examined, and ways in which they influence the overall work force planning problem are shown. It was found that absence is more a habit than a result of a decision process based on past overtime worked. Strong linear relationship was found between absence and overtime. This result makes it possible to include reliability constraints in the strategic work force planning process by setting an upper limit on the amount of overtime that can be planned for a given period. In addition, a two-stage heuristic is developed for solving the strategic work force planning problem. This heuristic is used in a case study of the Massachusetts Bay Transportation Authority bus system to show the importance of various policies with respect to work force planning and management.
