Generalized column generation for linear programming
(Institute for Operations Research and the Management Sciences (INFORMS), 2002)
Column generation is a well-known and widely practiced technique for solving linear programs with too many variables or constraints to include in the initial formulation explicitly. Instead, the required column information ...
Dynamic lot sizing and tool management in automated manufacturing systems
The overall aim of this study is to show that there is a critical interface between the lot sizing and tool management decisions, and these two problems cannot be viewed in isolation. We propose "ve alternative algorithms ...
A new dominance rule to minimize total weighted tardiness with unequal release dates
We present a new dominance rule by considering the time-dependent orderings between each pair of jobs for the single machine total weighted tardiness problem with release dates. The proposed dominance rule provides a ...
A simulation based learning meachanism for scheduling systems with continuous control and update structure
A simulation based learning mechanism is proposed in this study. The system learns in the manufacturing environment by constructing a learning tree and selects a dispatching rule from the tree for each scheduling period. ...
Integrated scheduling and tool management in flexible manufacturing systems
(Taylor & Francis, 2001)
A multistage algorithm is proposed that will solve the scheduling problem in a flexible manufacturing system by considering the interrelated subproblems of processing time control, tool allocation and machining conditions ...
Tree network 1-median location with interval data: a parameter space-based approach
(Taylor & Francis, 2005)
We consider a family of 1-median location problems on a tree network where the vertex weights are ranges rather than point values. We define a new framework for making sound decisions under uncertainty which is primarily ...
