comin the present study, co2 removal from natural gas stream has been studied using a flat sheet membrane contactor. a three dimensional mathematical model is developed to describe the process. the model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. the model is based on the non-wetted mode of operation, in which t...

This paper is the result of the work carried out to study the performance analysis of two stage supply chain network using simulation. The objective of study is to model an integrated system for a two stage supply chain network of an automobile company and measuring the performance parameters and establishing the priority decision and queuing rules for improving the utilization of resources. Th...

water conveyance systems (wcss) are costly infrastructures in terms of materials, construction, maintenance and energy requirements. much attention has been given to the application of optimization methods to minimize the costs associated with such infrastructures. historically, traditional optimization techniques have been used, such as linear and non-linear programming. in this paper, applica...

We discuss SISCO, the Simulator for Integrated Supply Chain Operations, a Java-based tool that simplifies supply chain simulation model development. SISCO maps supply chain descriptions stored in the XML-based Supply Chain Modeling Language (SCML) format to a set of supply chain “building blocks” developed with ThreadTec’s SilkTM simulation classes. The resulting system combines the ease of a v...

In this work, different procedures for sensor Fault Detection and Isolation (FDI) applied to a simulated model of a commercial aircraft are presented. The main point of the paper regards the design of two FDI schemes based on a linear Polynomial Method (PM) and the NonLinear Geometric Approach (NLGA). The obtained results highlight a good trade–off between solution complexity and achieved perfo...

always allocate man - machine is considered as one of the main concerns of operation planners. utilize an appropriate using of workforce in situations that the operation is dependent on the capabilities of the workforce, can lead to improve the systems efficiency and productivity indicators. since these issues, categories in np-hard problems, so optimization and solving the mathematical model o...

organizations in order to capture sustainability and competitive advantage need to pay attention to environmental issues throuoghout their supply chain. by decreasing costs, improving image and being protected against environmental laws it can lead to organizational competitive advantage. current research has been done investigating the relationship between green supply chain and capturing cope...
