Seven energy sources usable for lighting in households have been evaluated against 12 (9 quantitative and 3 qualitative) objectives representing the energy-economy-environmental system using an integrated goal programming-AHP model. Sensitivity analysis has been performed. While photovoltaics, grid electricity, and electricity generated from diesel, biogas and fuelwood are preferred, the use of kerosene and biogas requires efficiency improvements of the lamps. © 1995.

Energy alternatives for lighting in households: An evaluation using an integrated goal programming-AHP model

Energy

AHP has been used for solving multi-criteria resource allocation problems by converting them into equivalent single objective, maximization-type LP problems. At least two approaches can be identified for such applications. In the first approach, the AHP priorities are used as coefficients in the objective function of the LP format, and in the second approach, the benefit-cost ratios are used as the coefficients. This paper evaluates the two approaches. It is shown here that both the approaches are suitable if the criteria (used in the AHP model) are sought to be maximized. However, they are shown to be inappropriate if the criteria are sought to be minimized. A new, simple approach is suggested for the latter case and an extension has been proposed to tackle problems with mixed criteria. The implications of the study on other preference elicitation methods have also been pointed out. © 1995.

Using AHP for resource allocation problems

Fifteen cooking energy sources have been evaluated using nine objectives representing the energy-economy-environmental system. Scenario development and a sensitivity analysis have also been performed. While lignite, LPG, natural gas, biogas, solar thermal, and decentralized electricity generation from fuelwood gasification are preferred, the use of kerosene and fuelwood requires efficiency improvements of cook stoves. Coal, soft coke, charcoal, photovoltaics, grid electricity, and electricity generated from biogas or diesel have not been preferred due to either high costs or low efficiencies. © 1994.
