A novel Lagrangian relaxation approach for a hybrid flowshop scheduling problem in the steelmaking-continuous casting process

Mao, Kun; Pan, Quan-ke; Pang, Xinfu; Chai, Tianyou - In: European Journal of Operational Research 236 (2014) 1, pp. 51-60

One of the largest bottlenecks in iron and steel production is the steelmaking-continuous casting (SCC) process, which consists of steel-making, refining and continuous casting. The SCC scheduling is a complex hybrid flowshop (HFS) scheduling problem with the following features: job grouping and...

A stochastic approximation method for the single-leg revenue management problem with discrete demand distributions

Kunnumkal, Sumit; Topaloglu, Huseyin - In: Mathematical Methods of Operations Research 70 (2009) 3, pp. 477-504

We consider the problem of optimally allocating the seats on a single flight leg to the demands from multiple fare classes that arrive sequentially. It is well-known that the optimal policy for this problem is characterized by a set of protection levels. In this paper, we develop a new...
