A tabu search algorithm for the multi-stage parallel machine problem with limited buffer capacities
Bagas Wardono,Yahya Fathi +1 more
TL;DR: A tabu search algorithm is developed for the problem of scheduling N jobs on parallel machines in L successive stages with limited buffer capacities between stages, and a procedure to construct a complete schedule associated with every permutation vector is proposed.
Proceedings ArticleDOI
Exact and inexact methods for selecting views and indexes for OLAP performance improvement
TL;DR: This paper develops an algorithm that effectively and efficiently prunes the space of potentially beneficial views and indexes when given realistic-size instances of the OLAP view- and index-selection problem, and provides formal proofs that the resulting integer-programming model is guaranteed to find an optimal solution.
Journal ArticleDOI
On the sensitivity of project variability to activity mean duration
TL;DR: The main contribution of this paper is to study the impact of changing the mean duration of an activity on the variability of the project duration, and investigate the accuracy of Taguchi's sampling technique as a method for analyzing the network.
Journal ArticleDOI
A nonlinear programming approach to the parameter design problem
TL;DR: The Successive Quadratic Variance Approximation Method (SQVAM) as mentioned in this paper is based on conventional optimization techniques, and assumes that the functional relationship between the input parameters and the performance characteristic of interest is either known or could be well approximated.
Journal ArticleDOI
Generalized mixed integer rounding inequalities: facets for infinite group polyhedra
Kiavash Kianfar,Yahya Fathi +1 more
TL;DR: It is proved that the n-step MIR inequalities generate two-slope facets for the infinite group polyhedra, and hence are potentially strong.
