Research paper thumbnail of Creating A Green Supply Chain: A Simulation and Modeling Approach

The paper creates a green supply chain by integrating the concerns of transport pollution, marketing costs, time to market, recycling of scrap metal and energy conservation. Simulation and modelling tools are introduced to aid in the decision-making process of distance selections and choices of transportation in the case study. Based on a series of user-input selections, the simulation results are used to determine a range of optimal plant locations that will balance economic benefits (highest scrap values, least total costs, etc.) as well as environmental stewardship (least pollution). Ian Bainbridge has degrees in metallurgy and commerce from Melbourne and is currently undertaking a PhD degree at the University of Queensland, Australia. He has been involved in the aluminium industry for over 40 years and presently operates his own metallurgical consulting business specialising in aluminium and magnesium casting and specialty products production.

The expert system directs the user through advice on likely causes and effects of surface features for a variety of engineering applications. The expert system furnishes details concerning the effects of surface features on the functional performance of surfaces and then relates these features to the machining conditions that are likely to produce the given characteristics. The analytical details of the surface characterisation scheme which actually links the information together remains invisible throughout. By presenting only information and results which are required by the practising engineer and not the analysis necessary to arrive at those results, the expert system provides a powerful natural language tool, in a terminology readily understood by the engineer in a manufacturing and design environment. The expert system thus provides a medium by which the \u27loop\u27 between manufacture and performance can be completed

The simulation model is able to undertake real-time forecasting of the expected behaviour of the cell, and also able to display in real time the current status of the assembly cell. The potential of integrating artificial neural networks into simulation together with an on-line real-time interface between the simulation model and the real-world system is investigated in this study. A simulation model was built in SIMAN with a neural network written in NeuralWork Professional II Plus embedded in the model to allow training and testing of the network. The control of the cell was achieved through a third-party program written in C that interfaces directly to the cell.

This is especially true in process industries where once infrastructure is in place, supply chain performance is largely bound by the operational policies used to manage day to day operations. Linking performance outcomes to a change in operations policies is difficult, as key policy choices interact in non-linear and counterintuitive ways. In this study, we measure the variance induced by changes in operations policy to develop a proxy measure that captures the utility of individual performance metrics and a composite index. Results provide a deeper understanding of how performance measurement systems can be designed to better capture the influence of day-to-day managerial choices on supply chain operations.
