Nowadays energy saving is one of the crucial aspects in decisions. One of the approaches in this case is efficient use of resources in the industrial systems. Studies in real manufacturing systems indicating that one or more machines may also act as the Bottleneck Resource/ Resources (BR). On the other hand according to the Theory of Constraints (TOC), the efficient use of resources in manufact...

Multi-criteria approaches to analysis of complex issues in coupled human-environment systems have found wide application across business, government and communities around the world. Increased attention has been paid to spatial implementations of multi-criteria analysis. Spatial capability is available in several GIS, such as IDRISI and ArcView, and is often customised for particular problems i...

_ ABSTRACT .w We study multi-Higgs models under the assumption that new physics exists at some high energy scale (RNP). If we perform the minimally required fine-tuning in order to set the electroweak scale (AEw), we find that the low-energy scalar spectrum is identical to that of the Standard Model with minimal Higgs content, up to corrections of order A$&/A&,. If, in addition, the model is su...

This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...

‎This paper proposes a multi-supplier multi-product inventory model in which the suppliers have unlimited production capacity, allow delayed payment, and offer either an all-unit or incremental discount. The retailer can delay payment until after they have sold all the units of the purchased product. The retailer’s warehouse is limited, but the surplus can be stored in a rented warehouse at a...
