Material flow modeling constitutes an important approach to predicting and understanding the flows of materials through the anthroposphere into the environment. The new “Dynamic Probabilistic Material Flow Analysis (DPMFA)” method, combining dynamic material flow modeling with probabilistic modeling, is presented in this paper. Material transfers that lead to particular environmental stocks are...

This Supplementary Material is intended to provide a detailed description of the material flow analysis (MFA) model and to report the main data sources utilized to characterize the lifecycle of Cu in the EU-28. More details on accounting equations can be found in [1,2]. As shown in Figure S1, lifecycle processes of a substance are linked by materials flows that describe the transformation from ...

The management and control of material flow forms the core of manufacturing execution systems (MES) in the petrochemical industry. The bottleneck in the application of MES is the ability to match the material-flow model with the production processes. A dynamic material-flow model is proposed in this paper after an analysis of the material-flow characteristics of the production process in a petr...

Previous researchers have developed ways of managing forward-oriented supply chains, and gave insight to solve single-stage inventory systems. In this study, we analyze an inventory system with traditional forward-oriented material flow as well as a reverse material flow supply chain. In the reverse material flow, the used products are returned, remanufactured and shipped to the retailer for re...

Combining modern thermodynamics theory branches, including finite time thermodynamics or entropy generation minimization, constructal theory and entransy theory, with metallurgical process engineering, this paper provides a new exploration on generalized thermodynamic optimization theory for iron and steel production processes. The theoretical core is to thermodynamically optimize performances ...

The bullwhip effect is a well-known phenomenon of demand information distortion in supply chains. To measure the bullwhip effect in a supply chain, researchers often resort to material flow data, i.e., shipments and sales data, as proxies for order and demand information. In this paper, we study the accuracy of such an approximated bullwhip measure and provide remedies for correcting the estima...

This paper describes the application of discrete event simulation to study continuous material flow. Logistics is an integrated part of most manufacturing companies. The purpose of this study is to determine the required logistics operations to allow continuous operations of a chemical manufacturing plant. The application has been used to provide critical decision support.
