value added is a criterion for evaluating the performance of economic units. statistics related to various economic indicators of industrial workshops located in iranian provinces with their value added are annually obtained by statistical centre of iran via “industrial workshops survey” program. this study is going to find the most important factors affecting the value added of the workshops, ...

The production and profit impacts of recombinant Bovine Somatotropin (rbST) on select New York dairy farms were estimated using data over the years 1994 through 2004, by comparing matching farms which use and do not use rbST. The use of rbST increases milk production per cow and decreases the cost of production per hundredweight of milk. The cost penalty (cost reduction) is $0.39 per hundredwei...

We present two approaches for conflict resolution between two fault detection schemes, detecting the same fault, via optimization with bounded adjustment of detection thresholds. In our first method, we assume initially that there is no conflict and optimize the thresholds of both schemes with respect to a partial cost function that penalizes false alarms and missed detections. Then we continuo...

Owing to rising intentional events, supply chain disruptions have been considered by setting up a game between two players, namely, a designer and an interdictor contesting on minimizing and maximizing total cost, respectively. The previous studies have found the equilibrium solution by taking transportation, penalty and restoration cost into account. To contribute further, we examine how incor...

We present a novel approach to the modeling of motor responses based on statistical decision theory. We begin with the hypothesis that subjects are ideal motion planners who choose movement trajectories to minimize expected loss. We derive predictions of the hypothesis for movement in environments where contact with specified regions carries rewards or penalties. The model predicts shifts in a ...

We propose a new class of Foundation-Penalty (FP) cuts for GUB-constrained (and ordinary) mixed-integer programs, which are easy to generate by exploiting standard penalty calculations that are routinely employed in branch-and-bound contexts. The FP cuts are derived with reference to a selected integer variable or GUB set, and a foundation function that is typically a reduced cost function corr...

This work proposes a formulation for coordinating between collection and disassembly planning for an End-of-Life (EOL) product. The coordination deals with the balance between the number of products collected, the inventory level and the number of products disassembled. The objective function aims to minimize the total cost including the disassembly cost, the penalty cost, the holding cost and ...
