Multi-Objective Combinatorial Optimization (MOCO) problems find a wide range of practical application problems, some of which involving Boolean variables and constraints. This paper develops and evaluates algorithms for solving MOCO problems, defined on Boolean domains, and where the optimality criterion is lexicographic. The proposed algorithms build on existing algorithms for either Maximum S...

| We describe a general method for optimized design of CMOS operational ampli ers. We observe that a wide variety of design objectives and constraints have a special form, i.e., they are posynomial functions of the design variables. As a result, the ampli er design problem can be expressed as a special form of optimization problem called geometric programming, for which very e cient global opti...

Today’s dilemma of the manufacturing system is to realize stable processes while manufacturing’s environment is affected by global competition, high degree of complexity and autonomy, short delivery times and high product variety. In order to guarantee the requested product quality and reduce downtime, the smart manufacturing (SM) which is considered as a new trend helps to meet objectives asso...

This paper provides an empirical assessment of the implications of delegating monetary policy to a central bank. We argue that the theoretical literature justifying central bank independence is highly stylised and is deficient in that it assumes there is only a single policy instrument under the control of a single policymaking authority and it typically assumes rational expectations. We are ab...

Natural gas is a main source of energy in Iran, and optimal allocation to different sectors crucial, based on realities, geopolitical considerations, national security concerns. In this paper, multi-objective goal programming model developed study the resource various consumption sectors, including household business, industry, petrochemical power plants, injection oil fields, export from Iran ...

The first step in studying the behavior of a pipe network is to identify the objectives that must be attained and the physical and logical problems that must be solved; this aim can be achieved by building a suitable model of the network. The next step must be the operation of the model (which, for example, in the case of numerical models consists of using an appropriate algorithmic procedure) ...
