this paper is focused on the tactical design of steel supply chain (ssc). a general mathematical model is proposed to integrate production and transportation planning in multi-commodity ssc. the main purpose is to prepare a countrywide production and distribution plan in an ssc with three layers consisting of iron ore mines as suppliers, steel companies as producers, and subsidiary steel compan...

This paper proposes an approach to generate blending plans using a cooperative multi-agent system. First, a model for the blending problem in batch manufacturing is developed based on operations research principles, which takes into consideration of factors involved in blending plan generation. Second, the architecture of the system is introduced. We describe the structures of control agent and...

Blending sharp edges in solid models is an important task of Computeraided design. The prominent algorithms for producing blending fillet surfaces relay mostly on the rolling-ball method. These algorithms are applied on B-Rep solid models that are used in many CAD/CAM systems. Such solid models allow for a hierarchical approach of modeling which can incorporate blending operations within its st...

Coal blending is a critically important process in the coal mining industry as it directly influences the number of product tonnes and the total revenue generated by a mine site. Coal blending represents a challenging and complex problem with numerous blending possibilities, multiple constraints and competing objectives. At many mine sites, blending decisions are made using heuristics that have...

Automatic blending between surfaces surrounding skeletal elements has been cited as one of the chief advantages of using implicit surface modeling techniques. However, achieving control so that blending occurs only when it is desirable is a di cult problem. In this paper we look at using a graph to specify the blending between objects. We propose a new method which produces a C(0) continuous fu...

Blending biomass materials of different physical or chemical properties provides an opportunity to adjust the quality feedstock meet specifications conversion platform. We propose a model which identifies right mix optimize performance thermochemical process at minimum cost. This is chance-constraint programming (CCP) takes into account stochastic nature quality. The proposed CCP ensures that r...
