In the realm of personnel scheduling, where demand is subject to variability, the creation of a work schedule for irregular worker presents a significant challenge. This difficulty is amplified when the specific shift types are not predefined and when workers possess varying levels of availability and distinct skill sets. Additionally, due to legal and cost constraints, personal preferences, and fairness considerations, the scheduling problem becomes even more complex. The typical personnel scheduling process generally consists of two main stages: shift design and shift assignment. During the shift design stage, a scheduler designs a set of shifts and calculates the required number of workers to meet the demand. The shift assignment stage involves allocating workers to each individual shift, while satisfying various constraints to achieve certain objectives.The shift design and assignment stages can be approached as a single problem or solved as two separate problems. In this paper, a two-phase method is investigated, where the first phase is addressed by an integer programming approach, and the second phase is solved using a memetic approach. Real-world retail store scheduling instances are used to test and compare these methods. The solution time and quality suggest that the proposed methods can be effectively applied to solve the irregular scheduling problem commonly encountered in retail stores.

“…Günther and Nissen [20,21] scheduled workers on workstations (jobs) in one German logistics provider, where most of the jobs are related to the warehouse. Both papers have solved the same problem, but used different techniques to do so, with both aimed at improving the existing schedule of workers during the day.…”

“…Bard and Wan [22] scheduled workers on workstations in a way that the demand for workers of every workstation was defined in half-hour intervals, every day, five days a week. The scheduling of workers on workstations, which corresponded to the activities, was conducted in a study by Günther and Nissen [21]. The results of the study indicate that on each workstation, in each interval of the day, a certain number of workers are needed.…”

A New Sustainable Warehouse Management Approach for Workforce and Activities Scheduling

et al. 2021

Sustainable engineering is very important for logistics systems. Nowadays, sustainable warehouse management is a key factor in market success. Workforce fluctuation and inverting the number of customers’ demands make a lot of problems in distribution warehouses. This study addresses a sustainable approach for the workforce scheduling problem recognized in a real distribution warehouse. The problem arises from the high variability of demand for workers over one workday, which causes workforce surplus in some periods of the workday and shortages in others. Engineering managers of the distribution warehouse already use different full-time and part-time shifts, and schedule workers on different activities, but they still have significant workforce surpluses or shortages in some periods. This study proposes the scheduling of activities’ execution together with workers to face that variability and decrease the cost of the workforce. This idea comes from the fact that some activities in a distribution warehouse can be done in a specific time period after the need for them occurs. In this way, the variability of demand for workers can be decreased, and a lower workforce cost may be ensured. Based on this idea, the entire problem is modeled as integer linear programming. The real example of the problem is solved, and the proposed model is tested on randomly generated instances of the problem in Python by means of the PuLP linear programming package. The results indicate different positive effects in the manner of sustainable warehouse management: lower workforce costs, time savings, better utilization of all types of resources and equipment, increased employee satisfaction, and so on. For even 61% of instances of the introduced problem, the obtained cost of the workforce is lower by more than 20% if activities’ executions are scheduled together with employees.
