In this paper the authors present a case study from the woodprocessingindustry. It focuses on a cutting process in which material fromstock is cut down in order to provide the items required by the customersin the desired qualities, sizes, and quantities. In particular, two aspectsmake this...

This paper presents a linear programming approach to analyze and optimizeow lines with limited buer capacities and stochastic processing times. The basic ideais to solve a huge but simple linear program that models an entire simulation run of amulti-stage production process in discrete time, to...

This paper shows that cycling of the simplex method for the m×n Transportation Problemwhere k-1 zero basic variables are leaving and reentering the basis does not occur once it doesnot occur in the k×k Assignment Problem. A method to disprove cycling for a particular k isapplied for k=2,3,34,5...

Providing a good formulation is an important part of solving a mixed integer program.We suggest to measure the quality of a formulation by whether it is possible tostrengthen the coefficients of the formulation. Sequentially strengthening coefficientscan then be used as a tool for improving...

Sharpe style regression has become a widespread analytic tool in the financial community. Thestyle regression allows one to investigate such interesting issues as style composition, style sensitivity, andstyle change over time. All previous methods to obtain the distribution and confidence...

Background: Traceability systems and carbon emissions are two important factors involved in production and distribution activities. The involvement of these two factors in production and distribution activities along the supply chain will ensure the safety and quality of food through the...

We consider consistent tests for stochastic dominance efficiency at any order of a given portfolio with respect to all possible portfolios constructed from a set of assets. We justify block bootstrap approaches to achieve valid inference in a time series setting. The test statistics are computed...

This paper treats the problem of setting the inventory level of closed-loop owlines operating under the constant-work-in-process (CONWIP) protocol. We solve ahuge but simple linear program that models an entire simulation run of a closed-loopow line in discrete time to determine a production...
