Supplier dependence and innovation: a contingency model of suppliers' innovative activities
(Elsevier, 1990-09)
The management of innovation is a complex task and the management of suppliers' innovative activities is especially so because it involves managing technological factors across the traditional boundaries of the firm. This ...
New iterative methods for linear inequalities
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1992-01)
New iterative methods for solving systems of linear inequalities are presented. Each step in these methods consists of finding the orthogonal projection of the current point onto a hyperplane corresponding to a surrogate ...
Estimating the throughput of an exponential CONWIP assembly system
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1993-03)
We consider a production system consisting of several fabrication lines feeding an assembly station where both fabrication and assembly lines consist of multiple machine exponential workstations and the CONWIP (CONstant ...
Segments in enumerating faces
(Springer-Verlag; The Mathematical Programming Society, Inc., 1995-10)
We introduce the concept of a segment of a degenerate convex polytope specified by a system of linear constraints, and explain its importance in developing algorithms for enumerating the faces. Using segments, we describe ...
Examination of the effect of tool mass and work postures on perceived exertion for a screw driving task
(Elsevier, 1993-08)
Eighteen subjects with industrial work experience drove screws into perforated sheet metal at three vertical (64, 114 and 165 cm) locations with a pistol-shaped tool, and at two horizontal (13 and 63 cm) work locations ...
Optimal Sequencing of Inspection of Dependent Characteristics
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1999-12)
We address the problem of sequentially inspecting the dependent characteristics of a product, where the dependency is expressed in terms of the joint probabilities of the fitness of the characteristics. We show that, even ...
Dynamic system-optimal traffic assignment using a state space model
(Elsevier, 1993-12)
We propose a new mathematical formulation for the problem of optimal traffic assignment in dynamic networks with multiple origins and destinations. This problem is motivated by route guidance issues that arise in an ...
Improving Hit-and-Run for global optimization
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-06)
Improving Hit-and-Run is a random search algorithm for global optimization that at each iteration generates a candidate point for improvement that is uniformly distributed along a randomly chosen direction within the ...
The effectiveness of a joint labor-management program in controlling awkward postures of the trunk, neck, and shoulders: Results of a field study
(Elsevier, 1993-01)
Awkward working posture at the trunk, neck and shoulders may be caused by a number of factors, including: workstation layout, visual demands of the job, design of equipment and tools, and work methods. Because awkward ...
