Auction Algorithms on Job Shop Scheduling Problem

Job Shop Scheduling Problem
  • A set of job is to be completed and each job
    requires a set of machines for a certain period
    of time for processing .
  • Each job consists of a series of operations that
    represent the production steps of the job .
  • Each operation needs a certain machine for a
    certain time period called processing time .

3
Constraints
  • Non-preemption constraints
  • Precedence constraints
  • Capacity constraints
  • Scheduling Objective
  • To minimize total weighted tardiness

Job(Bidder) operations

Bid for the time slots of each machine
Broker(Auctioneer)
Resources allocation

non-preemption constraints
precedence constraints
capacity constraints
integrality constraints

Combinational Auction
is a subset of
is a subset of
Non-preemption constraints
job is overall bid
7
job js utility function is defined as follows
the best bid for job is one that
maximizes the utility function
8
A strategy is to have the auctioneer raise the
prices in proportion to the excess demand as
follows
