This paper describes models that estimate the cost and time of sheet metal punching when nesting (batching) orders. These models help decision-makers plan production and evaluate the impact of changing the nesting policy. ...

This paper describes a two-space genetic algorithm that finds solutions to minimax optimization problems. The genetic algorithm maintains two populations and searches both simultaneously. Each individual is evaluated with ...

The processing of a task on a machine often requires an operator to setup the job. In this paper we consider the problem of scheduling a finite set of jobs on a number of identical parallel machines. Each job has a setup ...

This paper considers the problem of designing a network to transport material from sources of supply to sites where demand occurs. However, the demand at each site is uncertain. We formulate the problem as a robust discrete ...

This paper considers the problem of minimizing the fixed cost of acquiring material handling transporters and the operational cost of material transfer in a manufacturing system. This decision problem arises during ...

This paper compares two gradient estimation methods that can be usedfor estimating the sensitivities of output metrics with respectto the input parameters of a stochastic manufacturing system.A brief description of the ...

In this paper we consider the design of material handling flow paths in a discrete parts manufacturing facility. A fixed-charge capacitated network design model is presented and two efficient heuristics are proposed to ...
