Multiobjective problems usually contain conflicting objectives. Therefore, there is no single best solution but a set of solutions that represent different tradeoffs between these objectives. Knowledge of this front can help in understanding the optimization problem better, as promising designs can be identified, and it can be seen what the achievable tradeoffs between the objective values are....

a new integrated model is developed for information systems planning. in this model, entitled hisspm, a combination of the strengths of critical success factors (csf) method, analytic hierarchy process (ahp) technique and genetic algorithms (ga) is used to identify and prioritize the required information systems. this model considers both qualitative and quantitative factors, as well as the imp...
