Queueing Theory: A Problem Solving Approach

A Constraint Programming Approach for Solving a Queueing Control Problem

In a facility with front room and back room operations, it is useful to switch workers between the rooms in order to cope with changing customer demand. Assuming stochastic customer arrival and service times, we seek a policy for switching workers such that the expected customer waiting time is minimized while the expected back room staffing is sufficient to perform all work. Three novel constr...

A Problem-Solving Approach

A balance theory approach to group problem solving

This paper presents a view of group problem solving based on Heider’s balance theory (Cartwright & Harary, 1956; Doreian, Kapuscinski, Krackhardt, & Szczypula, 1996; Heider, 1946, 1958), which conceptualizes the problem solving process as a progression towards increasing structural balance. Balance theory provides a means of representing problems in ways that capture both gestalt restructuring ...
