Optimization and sustainable development

In this opinion paper, I argue that “optimization and sustainable development” indicates a set of specific engineering techniques rather than a unified discipline stemming from a unique scientific principle. On the other hand, I also propose a mathematical principle underlying at least some of the concepts defining sustainability when optimizing a supply chain. The principle is based on the fac...

Streamlining the planning approval process for a sustainable urban development: A case study for unwinding man-made complexities

The urban development process displays regressive tacit-dominant knowledge areas and their tacit level would impede their movements during multi-level knowledge transfers among stakeholders. The accuracy of a knowledge may be distorted when recipient stakeholders fail to understand a specific knowledge for its purpose. Earlier studies by the authors had highlighted complex yet dynamic environme...

Implementation of flotation and gravity separation, to process Changarzeh sulfide-oxide lead ore

This study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% Pb, 1.91% Zn taken from Changarzeh mine, South Natanz, Iran. The effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, pH and solid content were investigated in relation t...
