We study a make-to-order manufacturing system consisting of several process
ing centers that are subject to failures and repairs. Our objective is to b
uild a model that can be used as a tool for negotiating the delivery date a
nd the price of a certain upcoming order. The model takes into account the
congestion level of the shop floor at the time the order is placed. Based o
n the workload of the processing centers, the model splits the order into l
ots and assigns them to the processing centers so as to determine the order
completion time associated with the minimum operating cost. The efficiency
of the solution method for the model allows real-time decision-making whil
e negotiating the price and delivery date of the order to be placed. Since
the decisions are made based on a snapshot of the congestion level at the s
hop floor, using this model will reduce the conflict between the marketing
and the production activities in manufacturing organizations.
