Multi-objective optimization is known as a useful mathematical model in order to investigate some real world problems with connicting objectives, arising from economics, engineering and human decision making. In this paper, a convex composite multi-objective optimization subject to a closed convex set constraint is studied. New rst-order optimality conditions of a weakly eecient solution for th...

The paradigm of multi-criteria decision making considers not only many attributes in the decision-making process but also the optimization of a number of objectives to accomplish certain targets. A multi-objective programming problem is a problem involving the simultaneous optimization of various, often conflicting, objective functions under certain given constraints to find compromise solution...

The decision of information technology (IT) outsourcing requires close attention to the evaluation of supplier selection process because the selection decision involves conflicting multiple criteria and is replete with complex decision making problems. Selecting the most appropriate suppliers is considered an important strategic decision that may impact the performance of outsourcing engagement...

Until recently, the main focus of researchers that develop algorithms for evolutionary multi-objective optimization has been the creation of mechanisms capable of obtaining sets of solutions that are as close as possible to the true Pareto front of the problem and also as diverse as possible in the objective space, to properly cover such front. However, an adequate maintenance of diversity in t...

Traditional pavement maintenance, rehabilitation, and reconstruction (MRR) planning accounts for user cost by maximizing drivers’ comfort, reducing users’ travel delay, minimizing fuel consumption, while controlling the agency’s costs of undertaking necessary preservation activities. Safety performance is seldom considered in MRR pavements. However, condition has a large impact on crash frequen...

According to the characteristics of emergencies, a dynamic multi-objective emergency decisionmaking model is proposed. By introducing triangular fuzzy Numbers calculate correlation distance between selected solution, ideal solution and negative considering degree solutions, indexes highlighted. In addition, paper strengthens processing uncertain information in real world through comprehensive i...

Long-term planning is a challenging process for dealing with problems in big industries. Quick and flexible process of responding to the existing variable requirements are considered in such problems. Some of important strategic decisions which should be made in this field are, namely the way that manufacturing facilities should be applied as well as assignment and design the system of delivery...
