Optimization modeling and simulation of the autothermal reactor in the methanol production process was effectively done using the quasi –Newton scheme of optimization in Aspen Hysys 2006.5. The primary variables selected for this modeling were heat flow value of the following: Steam1;steam2; coolant1; coolant2; coolant3. After running the process optimization simulation, total cost was minimize...

Development of agriculture depends on optimal land allocation. The development towards optimal utilization of land under cultivation and thereby increasing the production of crops and profit with less fertilizer consumption have to be taken into consideration in agriculture planning. In this paper different agriculture strategies are developed and accordingly, single objective optimization mode...

During transition, maintaining employment and providing a social safety net to the unemployed are important to social stability, which in turn is crucial for the productivity of the whole economy. Because independent institutions for social safety are lacking and firms with strong profit incentives have little incentives to promote social stability due to its public good nature, state-owned ent...

For some management programming problems, multiple objectives to be optimized rather than a single objective, and objectives can be expressed with ratio equations such as return/investment, operating profit/net-sales, profit/manufacturing cost, etc. In this paper, we proposed the transformation characteristics to solve the multi objective linear fractional programming (MOLFP) problems. If a MOL...

Computing utilities are emerging as an important part of the infrastructure for outsourcing computer services. One of the major objectives of computing utilities is to maximize their net profit while maintaining customer loyalty in accordance with the service level agreements (SLAs). Defining the SLAs conservatively might be one easy way to achieve SLA compliance, but this results in underutili...
