“…Multiple contract types are considered by [12,19,20], who distinguish full-time and part-time employees, i.e., they consider employees with different contract hours. In addition to full-time and part-time contracts, [4,[6][7][8][9] also consider subcontractors. In this paper, we consider full-time contracts, part-time contracts, min-max contracts and subcontractors.…”

We propose a mathematical programming formulation that incorporates annualized hours and shows to be very flexible with regard to modeling various contract types. The objective of our model is to minimize salary cost, thereby covering workforce demand, and using annualized hours. Our model is able to address various business questions regarding tactical workforce planning problems, e.g., with regard to annualized hours, subcontracting, and vacation planning. In a case study for a Dutch hospital two of these business questions are addressed, and we demonstrate that applying annualized hours potentially saves up to 5.2% in personnel wages annually.

“…The objective is to minimize expected mismatch between planned hours and realized requirement on capacity. Corominas and Pastor [34] proposed a method for re-planning working time under annualized hours when demand is uncertain. A MILP model was developed for the replanning problem with an objective to minimize the cost of new plan as well as the change of worker schedules.…”

“…Corominas et al [21] provided a scheme for classifying annualized working-hour problems, which leads to thousands of cases. These problems have, thus far, been addressed in one of two ways, either using simple heuristics [22][23][24], or more elaborate optimization approaches such as Integer Programming (IP), Mixed Integer Linear Programming (MILP), and Stochastic Programming (SP) [25][26][27][28][29][30][31][32][33][34][35].…”

Abstract. We have considered the problem of annualized hours (AH) in workforce management. AH is a method of distributing working hours with respect to the demand over a year. In this paper, the basic Manpower planning problem with AH flexibility is formulated as a fuzzy mathematical programming problem with flexible constraints. Three models of the AH planning problem under conditions of fuzzy uncertainty are presented using different aggregation operators. These fuzzy models soften the rigidity of the deterministic model by relaxing some constraints with the use of flexible programming. Finally, an illustration is given with a computational experiment performed on a realistic-scale case problem of an automobile company to demonstrate and analyze the effectiveness of the fuzzy approach over a deterministic model.
