A multi-hierarchical framework for ranking maintenance sustainability strategies using PROMETHEE and fuzzy entropy methods

Abstract: Today, maintenance plays a significant responsibility in all stages of equipment life due to strong government interests in environmentally conscious manufacturing. The need of the hour is to ignore the sparse attention to sustainable maintenance research and pursue valuable links between maintenance strategy and sustainable maintenance. In maintenance strategy choice, available reports have not sufficiently addressed the imbalance caused by uncertainties in maintenance practices. In addition, current reports on maintenance strategy sustainability focus on technical and economic aspects of maintenance and scantily treat environmental, social and safety criteria. This affects the quality of decisions in maintenance systems. To remedy this situation, this study applies fuzzy entropy weight and PROMETHEE (Preference Ranking Organisation Method for Enrichment Evaluation) in ranking maintenance sustainability strategies. The proposed approach is tested in a cement plant. Based on the choice criteria, the PROMETHEE methods results identified the best maintenance strategy as maintenance optimisation strategy. Workforce training strategy was identified as the worst maintenance sustainability strategy. These obtained results were compared with fuzzy TOPSIS (Technique of Preference Order by Similarity to Ideal Solution) approach and the practical application of the approach was verified. The results serve as a basis and a platform for further application of the approach in other manufacturing companies.

Nutraceuticals and Diet-based Phytochemicals in Type 2 Diabetes Mellitus: From Whole Food to Components with Defined Roles and Mechanisms

Abstract: Background Over the past decades, the development and use of an array of prescription medications have considerably improved the clinical management of type 2 diabetes mellitus and the quality of life of patients. However, as our knowledge of the associated risk factors and approaches to its management increases, the increasing roles of diet and the composition of the diet in the etiology and successful management of diabetes mellitus are being illuminated. Presently, a lot of attention is being given to nutraceuticals and certain phytochemicals that are integral parts of the human diet. It is believed that a clearer understanding of their roles may be crucial to 'non-invasive' or minimallyintrusive management, with regards to daily living of patients. In this review, an overview of nutraceutical components and phytochemicals that may be of benefit, or had been known to be beneficial in diabetes mellitus is given. Also, how the roles of such dietary components are evolving in the management of this disorder is highlighted. Lastly, the obstacles that need to be overcome before nutraceuticals can be considered as options for the clinical management of diabetes mellitus areconsidered. Conclusion Despite studies that demonstrate their efficacy, no nutraceutical or food-derived compound has been formally adopted as a direct replacement for any class of antidiabetic drugs.

Criteria Air Pollutants from Some Anthropogenic Combustion Processes in Lagos, Nigeria

Abstract: On October 12, 2005, a mysterious fog engulfed some parts of Lagos, the cause of which is yet to be identified As part of the on-going scientific attempts to identify its cause, this article examines the contribution of anthropogenic combustion processes to oxides of nitrogen (NOx), carbon monoxide (CO), sulphur dioxide (SO2), and particulate matter (PM10) in Lagos On the average, predicted emissions are: NOx, 343 × 104; CO, 146 × 106; SO2, 124 × 103; and PM10, 784 × 1013 ton/annum Vehicular emissions from road transportation is an identified major source of criteria air pollutants in the city because combustion of gasoline in buses generated about 32% and 77% of the predicted NOx and CO emissions, respectively Similarly, significant portions of predicted SO2 emissions (57%) come from low pour fuel oil (LPFO) combustion The highest emission of PM10 from wood fuel combustion, which is 83%, raises some concern due to its potential impact on indoor air quality Some control measures and ide
