MIE562: Scheduling

Overview: This course takes a practical approach to scheduling problems and solution
techniques, motivating the different mathematical definitions of scheduling with realworld scheduling systems and problems. The linking theme for the course is the use of
search (partition, relaxations, and inference) to solve hard combinatorial problems.
Topics covered include: job shop scheduling, timetabling, project scheduling, and the
variety of solution approaches including constraint programming, local search, heuristics,
and dispatch rules. Also covered will be information engineering aspects of building
scheduling systems. A group project will require the creation a scheduling system using
the Warp Shoes database. Evaluation will be based on three terms tests, the project, and
the final exam. Students should have a basic knowledge of standard optimization
techniques as taught in second and third year MIE courses.
Syllabus
MIE562 is a senior undergraduate and junior graduate course. The students are primarily
in their fourth year of an Industrial Engineering degree having already specialized in
Operations Research or Information Engineering. The course takes a modeling and an
algorithmic approach, emphasizing different types of scheduling problems, common
models for them, and common algorithms and solving frameworks (i.e., heuristics, tree
search within MIP and Constraint Programming, and local search/metaheuristics).
1. Project Planning: CPM, PERT, Graph theory concepts, Time/cost trade-off.
Emphasis is on the mechanics of CPM and PERT as they appear repeatedly in all
types of scheduling algorithms as well as some of the connections with graph
theory. (Students are not expected to know any graph theory).
Four lectures (Lec 3 – Lec 6)
2. Heuristics for Scheduling: Dispatch rules, Shifting bottleneck. Emphasis is
again on the mechanics with some mentions of restricted scheduling models
where dispatch rules guarantee optimality.
Three lectures (Lec 8 – Lec 10)
3. Search: Tree search (Partitioning, Relaxation, Inference, MIP solving,
Constraint Programming), Local search (Tabu search). The primary conceptual
content of the course are the ideas underlying search. These ideas are illustrated
by solving manufacturing scheduling problems. Some treatment of problem
modeling.
Seven lectures (Lec 11 – Lec 17)
4. Service Scheduling: Timetabling (Workforce Capacity, Operator Constraints,
Shift scheduling, Graph coloring, Bin packing), Sports scheduling (Problem
Decompositions), Hospital scheduling (Operating room scheduling, Nurse
Rostering). Search and modeling concepts are revisited and reinforced using
applications from the service sector. The text is supplemented with a number of
journal papers that students are expected to read and understand.
Nine lectures (Lec 18 – Lec 26)
5. Supply Chain and Distributed Scheduling: Concepts, Discrete vs.
Continuous Manufacturing, Problem and data aggregation,
Distributed/multi-agent scheduling. Manufacturing scheduling problems are
seen in the context of wider supply chain optimization goals and as local
problems in a network of self-interested agents.
Four lectures (Lec 27 – Lec 30)
6. Scheduling Systems: System architecture, A non-optimization perspective,
Scheduling and the web. The systems side of scheduling is presented with a
perspective on how real scheduling systems are used.
Three lectures (Lec 31 – Lec 33)
