In this study we use a thermodynamic framework to characterize the material and energy resources used in manufacturing processes. The analysis and data span a wide range of processes from "conventional" processes such as machining, casting, and injection molding, to the so-called "advanced machining" processes such as electrical discharge machining and abrasive waterjet machining, and to the va...

in the present paper, the study has been made to optimize the process parameters during machining of Inconnel-600 by wire electrical discharge machining (WEDM) using response surface methodology (RSM). Four input process parameters of WEDM (namely Peak Current (IP), Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Feed rate (WF)) were chosen as variables to study the process performance in t...

Enhancing energy efficiency is the key to realizing green manufacturing. One major area of interest in this regard improvement machine tools during production building materials. This project focuses on spiral milling wood plastic composites. To end, a response surface method was adopted develop model and establish relationship between conditions. Analysis variance based individual factors as w...

This paper presents a multi-player multi-issue negotiation model to solve a resource allocation problem. We design a multilateral negotiation protocol, by which rational players bid sequentially in consecutive rounds till a deadline. Every player’s bid is a combination of all resource allocations for himself. In this framework, we perform a thorough theoretical analysis of the negotiation with ...

This work explores the historical effectiveness of efficiency improvements in reducing mankind’s impact on the earth. Ten activities are analyzed, including pig iron production, aluminum production, nitrogen fertilizer production, electricity generation from coal, oil, and natural gas, freight rail travel, passenger air travel, motor vehicle travel, and refrigeration. The data and analyses pres...

This paper examines the allocation of productive resources within rural households of poor countries. Building upon the existing literature, it provides a consistent framework from which to study productive efficiency and intrahousehold equity. The topics discussed include returns to scale and household centralization; specialization and gender casting; separate spheres and commitment failure; ...

This paper is an endeavour to critically appraise the existing methods used for real-time simulation of machine tool dynamics with the emphasis on modelling and simulation of the dynamic behaviour of CNC machine tool feed drives and mechatronic systems for machine tools. The actual approaches for linking the feed drive models with structural models for CNC machine tools are examined. Also the f...
