A new approach to robust performance problems is proposed in this paper. The approach involves the optimisation of so-called performance weights subject to a constraint, formulated in terms of the structured singular value, which ensures the existence of a stabilising feedback compensator that achieves robust performance with respect to the optimised performance weights and an uncertain plant s...

This paper deals with the performance enhancement for crystallization unit of a sugar plant using genetic algorithm. The crystallization unit of a sugar industry has three main subsystems arranged in series. Considering exponential distribution for the probable failures and repairs, the mathematical formulation of the problem is done using probabilistic approach, and different...

This study examines the effects of the fit between generic manufacturing strategies (GMS) and manufacturing objectives upon strategically relevant plant level performance outcomes (e.g. cost-efficiency, quality, delivery, flexibility, and innovation). The proposition that plants with generic manufacturing strategies that are consistent (fit) with operational objectives will experience relativel...

The performance of every plant in an environment is an indicator of how the plant can withstand the various environmental conditions. This study investigated the toxicity of crude oil on the growth performance, chlorophyll contents, enzymatic activities and oxidative stress biomarkers of eight accessions of Zea mays. The growth enzyme (amylase and invertase) activities, as well as oxidative s...

This paper deals with the performance analysis of the screening unit in a paper plant using Genetic Algorithm. The screening unit in the paper plant has four main subsystems. These subsystems are arranged in series and parallel configurations. Considering exponential distribution for the probable failures and repairs, the mathematical formulation of the problem is done by Markov birth-death pro...

The energy saving and emission reduction in thermal plant is complex, with the open, non-equilibrium and interoperability features. In order to identifying the order parameters affecting plant system, a co-evolution model of energy saving and emission reduction in thermal power plant was built based on synergetic theory. According to the feathers of potential function based on mutation theory, ...

What is the role of information technology (IT) in enabling the outsourcing of manufacturing plant production processes? Do plant strategies influence production outsourcing? Does production process outsourcing influence plant performance? This research addresses these questions by investigating the role of IT and plant strategies as antecedents of production outsourcing, and evaluating the imp...

How insect herbivores affect plant performance is of central importance to basic and applied ecology. A full understanding of herbivore effects on plant performance requires understanding interactions (if any) of herbivore effects with plant density and size because these interactions will be critical for determining how herbivores influence plant population size. However, few studies have cons...
