摘要：The utility system design would consider the reliability to respond to boiler failure even shut down. The design would ensure system flexibility for the fluctuation of process steam demand as well. In this work, boiler system design was studied considering both the uncertainty of process steam demand and equipment failure based on mathematical programming. Probability distribution was used for fluctuation of process steam demand and the Markov model was used to deal with boiler failure to express uncertain parameter with probability. The approach of two-stage stochastic programming was to compensate the constraint violations caused by uncertain steam demand and boiler failure to reduce the effect on optimization and constraints. A mixed integer linear programming model (MILP) was formulated with the objective of minimum annual cost to design system configuration, equipment modes and operation of compensating flexible steam demand and equipment failure.
