This study focused on identifying various system boundaries and evaluating methods of estimating energy performance of biogas production. First, the output-input ratio method used for evaluating energy performance from the system boundaries was reviewed. Secondly, ways to assess the efficiency of biogas use and parasitic energy demand were investigated. Thirdly, an approach for comparing biogas...

The paper presents a holistic methodological approach for designing flexible production systems, integrating the management of the production resources, operations planning, internal logistics and quality. The proposed methodology relies on lean principles and encompasses a series of stages and tools that may be used to design and to assess the robustness of the production system for tackling s...

Based on the research project titled “AdaptivePlanningandControlofSupplyChaininOne-of-a-kind Production”, the research group performed a systematicreview ofsupply chain integration, riskprediction and control and traceability. Studies of a computer-aided and integrated production system for cost-effective OKP systemare included. Our efforts relevant to integration of supply chain in OKP, modeli...

W study inventory pooling in systems with symmetric costs where supply lead times are endogenously generated by a finite-capacity production system. We investigate the sensitivity of the cost advantage of inventory pooling to various system parameters, including loading, service levels, demand and production time variability, and structure of the production system. The analysis reveals differen...

This article presents an inquiry-research conducted in France (Cardoso 1996) which was aimed at identifying and analysing new forms of rationalisation of production employed in the building sector, both in France and Brazil, in the light of strategies of the building construction firms. The above mentioned research dealt with the issue of the productive competence of the building construction f...

As part of a project on adding value to farm operations with food-grade oils, the University of Vermont Extension and Pennsylvania State Extension teamed up to evaluate the design and operation of several small -scale oilseed presses. While there is a great deal of interest in the production of oilseeds, many questions arise about post-harvesting processing, and many of these concerns revolve a...

inventory management in production-remanufacturing system has been receiving a great deal of attention in recent years. in literature review, production environment is composed of two sections. the first section is included: production process, remanufacturing process and other options considered in reverse logistics. the second section is included: collection and sorting processes. determinati...

In recent years, farming section of South Khorasan Province faces different limitations such as increasing shortage of water resources and continuous reduction of weather showers.Considering consecutive droughts and water crisis in agricultural plain of the province, it is necessary to use water resources optimally and increase productivity of water shortage input. Comparison of water productiv...

Nowadays, production systems seek to integrate production and maintenance activities. An effective maintenance plan can improve maintenance stability and system performance. Machines that stop for repairing operation impose a high cost on the system. On the other hand, there are always some intangible situations during a production process in which repairing activities can be carried out. If th...
