An overview of the optimization modelling applications

SummaryThe optimal use of available resources is of paramount importance in the backdrop of the increasing food, fiber, and other demands of the burgeoning global population and the shrinking resources. The optimal use of these resources can be determined by employing an optimization technique. The comprehensive reviews on the use of various programming techniques for the solution of different optimization problems have been provided in this paper. The past reviews are grouped into nine sections based on the solutions of the theme-based real world problems. The sections include: use of optimization modelling for conjunctive use planning, groundwater management, seawater intrusion management, irrigation management, achieving optimal cropping pattern, management of reservoir systems operation, management of resources in arid and semi-arid regions, solid waste management, and miscellaneous uses which comprise, managing problems of hydropower generation and sugar industry. Conclusions are drawn where gaps exist and more research needs to be focused.

► A comprehensive review of various optimization techniques has been provided.
► Application of LP and DP techniques has been very popular in irrigation management.
► NLP has not been widely used because of rigorous mathematics involved.
► DP, MIP, DDP, CDDP, GA, and QP have extensively been used for groundwater management.
► Combined used of optimization and simulation models have been preferred recently.
