BT workforce scheduling problem considers technicians (with different skills) which are assigned to tasks which arrive (partially) dynamically during the day. In order to manage their workforce, BT divides the different regions into several areas. In the beginning of each day all the technicians in a region are assigned to one of these areas. During the day, tasks can only be allocated to techn...

With the economy continually moving towards retail and services, the size of the part-time workforce is increasing constantly. In this paper, we consider the problem of scheduling a workforce consisting entirely of part-time workers. The part-time workers have availabilities, preferences for the shifts, and also a seniority level. We propose an integer programming model to maximize employee sat...

The problem of designing workforce shifts and break patterns is a relevant employee scheduling problem that arises in many contexts, especially in service industries. The issue is to find a minimum number of shifts, the number of workers assigned to them, and a suitable number of breaks so that the deviation from predetermined workforce requirements is minimized. We tackle this problem by means...

Rotating workforce scheduling is a typical constraint satisfaction problem which appears in a broad range of work places (e.g. industrial plants). Solving this problem is of a high practical relevance. In this paper we propose the combination of tabu search with random walk and min conflicts strategy to solve this problem. Computational results for benchmark examples in literature and other rea...

Mathematical programming, constraint programming and computational intelligence techniques, presented in the literature in the field of operations research and production management, are generally inadequate for planning real-life production process. These methods are in fact dedicated to solving the standard problems such as shop floor scheduling or lot-sizing, or their simple combinations suc...

This paper explores the issue of choosing the best data to use when running a scheduling model to select a permanent workforce for a service facility. Because demand is assumed to vary over the day and throughout the week, the choice of the input data is crucial. If a week of low volume is selected, the solution might call for an insufficient number of workers; if a week of high volume is chose...

A four-day workweek days-off scheduling problem is considered. Out of the three days off per week for each employee, either two or three days must be consecutive. An optimization algorithm is presented which starts by utilizing the problem’s special structure to determine the minimum workforce size. Subsequently, workers are assigned to different days-off work patterns in order to minimize eith...

A workforce management problem in service industries is to determine how to allocate employees to jobs such that the service demand can be satis ed as much as possible at minimum cost. It has been studied in the Operations Research, Genetic Algorithms and other areas. Recently, Constraint Logic Programming (CLP) has provided a declarative and powerful tool which has been successfully used to so...

Sustainable engineering is very important for logistics systems. Nowadays, sustainable warehouse management a key factor in market success. Workforce fluctuation and inverting the number of customers’ demands make lot problems distribution warehouses. This study addresses approach workforce scheduling problem recognized real warehouse. The arises from high variability demand workers over one wo...
