Integrated Workforce Planning Considering Regular and Overtime Decisions

We consider the integrated workforce planning and allocation problem for a high volume manufacturing facility that operates in two non-overlapping shifts of twelve hours each day, with twenty eight shifts for a two week planing period. In such facilities, operational workforce planning is typically carried out in two steps consisting of the multishift assignments and the single-shift allocation. The multi-shift decisions balance the regular and overtime worker assignments to individual shifts based on capacity plans and worker availability during the two week planning period. The single-shift decisions ensure the worker-machine group allocations satisfy the qualification and skill-level requirements. In this paper, we present an integrated workforce planning model that makes these decisions for all the shifts during the two week planning period. Analyzing the regular and overtime allocation report provides insights in designing the cross-training programs.
