Most of the pre-existing modeling approaches for Automatic machining line (AML) concentrate on the equipment failure, but ignore some factors greatly influencing the performance of AML in production process, like the tool life, quality abnormality etc. Considering the above complex factors, a GSPN-based modeling approach is proposed to model the AML based on the fundamental principle of generalized stochastic petri nets (GSPN), which contributes to quantitatively analyze the relations between those factors and productivity of AML. The proposed modeling approach is applied in the automatic gear hobbing and shaving line in a gearbox factory. Some factors including equipment failure, cutting tool and quality abnormality are simulated to analyze the affections on the productivity, and the results show the validity of the approach.

In the framework of asset management, the effectiveness of an integrated process that manages reliability and maintenance should be adequately and timely evaluated based on a thorough analysis of a series of contributing factors, which should respond entirely to the result of maintenance activities on the performance of assets that make up the production process. According to the above, then arises the motivation for the design and application of tools to determine the effectiveness of such activities in asset management, understanding the latter as a holistic process that involves a diversity of functions and areas within an organization

For the first time, a steady state computational simulation for the production of biodiesel from meat processing dissolved air flotation sludge via an integrated process of in-situ hydrolysis and esterification technologies has been investigated. Important thermophysical properties of the intrinsic lipids of dissolved air flotation sludge were estimated using chemical constituent fragment methods. The environmental performance and the economic performance of the biodiesel production process were assessed via the estimation of the net energy ratio (NER) and the unit production cost, respectively. Since electrical energy requirements may be satisfied via either non-renewable (case A) or renewable sources (case B), the NER was determined for both scenarios. To enhance the robustness of the study results, uncertainties in the NER and the unit cost of the biodiesel production process due to the variability of the underlying study assumptions were also assessed. Uncertainty analysis indicated that the likely range of the NER for the biodiesel production process for cases A and B are 1.76 to 3.32 and 1.82 to 3.36, respectively, at 95% probability. Uncertainty analysis also showed that the likely range of the unit production cost for biodiesel is $US0.41/kg-biodiesel to $US0.71/kg-biodiesel at 95% probability. The results that were obtained in this study therefore provide evidence of both the environmental sustainability and the economic viability of biodiesel production from dissolved air flotation sludge via the proposed integrated process of in-situ hydrolysis and esterification.
