“…Substitution possibilities can also be obtained through cross-training. Campbell (1999) investigates the impact of the cross-utilisation of employees for different levels of demand variability (uncertainty of demand) and employee cross-training. Similarly, Olivella and Nembhard (2016) determine the optimal level of cross-training in work teams to deal with variations in the demand mix and employee availability.…”

Employee substitutability as a tool to improve the robustness in personnel scheduling

Organisations usually construct personnel rosters under the assumption of a deterministic operating environment. In the short term, however, organisations operate in a stochastic environment as operational variability arises. This variability leads to the occurrence of unexpected events such as employee absenteeism and/or a demand for personnel that is higher or lower than expected. In order to deal with these uncertainties, organisations need to adopt proactive and reactive scheduling strategies to protect the personnel roster and to respond to this operational variability, respectively. In this paper, we discuss a proactive approach that exploits the concept of employee substitutability to improve the flexibility of a personnel shift roster to respond to schedule disruptions. We propose a pre-emptive programming approach to construct a medium-term personnel shift roster that maximises the employee substitutability value. Moreover, we assess different proactive strategies to introduce robustness with respect to the definition and formulation of employee substitutability and different reactive strategies that impact the decision freedom for schedule recovery. The robustness of the generated personnel shift rosters is evaluated using a three-step methodology of roster construction, daily simulation and optimisation, and evaluation.

“…In this respect it touches on a significant body of literature that treats the problem of cross-trained workers from various perspectives. Campbell and Diaby (2002) develop heuristics for the model of Campbell (1999) which assigns cross-trained workers across different departments at the beginning of a shift. The departmental utility function is non-linear and the resulting model can be viewed as a variant of the GAP.…”

“…The second-stage is a recourse on realized demands. Sayın and Karabatı (2007) also build a framework based on the non-linear nature of the departmental objective function of Campbell (1999). They propose a two-stage model, where two objective functions, departmental utility and skill improvement, are considered in the assignment of cross-trained workers.…”

Management of Emergency Response Teams under Stochastic Demands

Abstract:We propose a stochastic optimization model for the composition of emergency response teams. An emergency intervention requires first an evaluation of the situation which results in the need of different skills. People involved in the response team must therefore comply with the required skills, be available, with a past and future workload respecting contractual compliance. In addition, we must also anticipate the possibility of future interventions that will require rare skills. It is the uncertain future demand for these skills that introduces stochasticities to the system. Since shifting agents between emergencies may be impossible or impractical, we would like to ensure that rare skills are not wasted but assigned to the emergency that most needs them. We model this with a mixed integer linear program implemented in AMPL and capable of being solved in real-time on common solvers.
