Scheduling the availability of order pickers is crucial for effective operations in a distribution facility with manual pickers. When order-picking activities can only be performed specific time windows, it essential to jointly solve picker shift scheduling problem and planning assigning sequencing individual orders This requires decisions regarding number schedule, start end times, break as we...

This paper introduces a new method for shift scheduling in multi-skill call centers. The method consists of two steps. First, staffing levels are determined and next, in the second step, the outcomes are used as input for the scheduling problem. The scheduling problem relies on a linear programming model that is easy to implement and has short computation times, i.e., a fraction of a second. Th...

Consider a production system that consists of m assembly stations arranged in series. All jobs enter the assembly line at station 1 and proceed with subsequent stations in the same order as in a ßow shop. Each job spends a Þxed amount of time c in each station, known as the production cycle. This production system is synchronous or paced because jobs move one station forward synchronously, ever...

The Workforce Scheduling and Routing Problem (WSRP) is a combinatorial optimisation problem that involves scheduling and routing of workforce. Tackling this type of problem often requires handling a considerable number of requirements, including customers and workers preferences while minimising both operational costs and travelling distance. This study seeks to determine effective combinations...

Labor costs are amongst the most important costs for companies in highly developed countries. While manufacturers move their production units en masse to low wage countries, service companies are often tied to their current locations. Unlike production, the service surplus value is often directly related to the place where the service is provided. Moreover, service companies generally require m...

In this paper, we define a set inequalities that are satisfied by stable multi-skill workforce schedules. In our analysis, a schedule is said to be stable if it does not contain a blocking pair, extending the notion of blocking pair in the Marriage Model of Gale-Shapley. Skill efficiency is chosen as the criterion in the preference structure. The proposed algorithm either constructs a stable mu...
