Abstract


Optimization also known as mathematical programming has been introduced and used since the beginning of the 20th century. Since then, many techniques and algorithms have been developed and applied in various fields. The past overviews of optimization modelling applications have been grouped in nine sections based on the solution to the theme-based real world problems, including Solid Waste Management (SWM). The objective of this paper is to analyse the various applications of optimization modelling and to determine their advantages and pitfalls, if any, in Solid Waste Management systems (SWMS). The method used is extensive literature survey and comparative analysis. Although other parameters such as environmental and social concerns cannot easily be modelled in the optimization process, it has been found that mathematical programming, along with simulation techniques, has been extensively used and has provided substantial benefits for the optimization of solid waste management systems around the world. The paper concludes by determining the optimization approaches that have been mostly used to optimize the SWMS by minimizing the total design and operations cost of different waste management infrastructures and resources; it describes the pros and cons of these methods, and it also identifies the gaps that exist in the application of optimization techniques and simulation in waste management.
