Negative valuation of undesirable outputs in evaluating the efficiency of production systems
MATEC Web of Conferences, 2017 This paper extends a data envelopment analysis (DEA) model that considers only desirable outputs in measuring efficiencies to incorporate undesirable outputs by requiring the associated multipliers to be negative.

Marginal productivity in two – stage network processes in the presence of undesirable outputs [PDF]
Muṭāli̒āt-i Mudīriyyat-i Ṣan̒atīIn production technology, studying the effect of an indicator on one or more other indicators while maintaining efficiency, named marginal rate, can provide valuable information to managers for better management of the system.

Analyzing for profit efficiency of banks with undesirable output
African Journal of Business Management, 2013 The primary objective of commercial banks is to maximize profit, but the usual ratio approach may encounter a problem when observed profit equals zero. This study uses the Nerlovian profit indicator, based on the difference rather than the ratio approach, to measure a profit efficiency indicator.

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
