Computational experience with a backtracking algorithm for solving a general class of precedence and resource-constrained scheduling problems
(Elsevier, 1990-11-06)
In this paper computational results are presented with a very general, yet powerful backtracking procedure for solving the duration minimization and net present value maximization problems in a precedence and resource-constrained ...
A simple proof of a primal affine scaling method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
In this paper, we present a simpler proof of the result of Tsuchiya and Muramatsu on the convergence of the primal affine scaling method. We show that the primal sequence generated by the method converges to the interior ...
Measuring the hedonic and utilitarian sources of consumer attitudes
(Kluwer Academic Publishers; Springer Science+Business Media, 1991-04)
It has been suggested theoretically that consumer attitudes have distinct hedonic and utilitarian components, and that product categories differ in the extent to which their overall attitudes are derived from these two ...
Stochastic scheduling of parallel queues with set-up costs
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1995-12)
We consider the problem of allocating a single server to a system of queues with Poisson arrivals. Each queue represents a class of jobs and possesses a holding cost rate, general service distribution, and a set-up cost. ...
One-dimensional cutting stock decisions for rolls with multiple quality grades
(Elsevier, 1990-01-25)
This paper presents a procedure for solving one-dimensional cutting stock problems when both the master rolls and customer orders have multiple quality gradations.The procedure described here is a two-stage sequential ...
Evaluation and derivation of process plans in turning
(Springer-Verlag; Springer-Verlag London Limited, 1996-05)
The objective of this paper is to formalize process planning selection to minimise the total processing time and the total number of processing steps. The study is performed by defining the processes and part description ...
Interfacial adhesion and toughening mechanisms in an alloy of polycarbonate/polyethylene
(Elsevier, 1992)
Interfacial adhesion and toughening mechanisms in an alloy of polycarbonate/polyethylene (PC/PE) are investigated using transmission electron microscopy. In contrast to the general speculation, it is found that the PE ...
Planning and scheduling approaches to operate a particular FMS
(Elsevier, 1992-09-25)
This paper contains a detailed description of a thirteen machine COMAU FMS for a company in Torino, Italy. The monthly and daily problems that need to be addressed and the approaches that are suggested to operate this ...
