In this paper we consider a multiobjective optimization problem, and we prove Mond-Weir duality results under second-and higher-order conditions of the objective and constraint functions.
In this paper, we propose a new recombination operator and test its performance in the context of the multiobjective 0/1 knapsack problem (MOKP). The proposed recombination operator generates only one offspring solution from a selected pair of parents according to the two following stages. In the first stage, called genetic shared-information stage or… (More)
— Faced with new environmental constraints, firms decide to collaborate in collective entities and adopt new patterns of behavior. So, this firms' collaboration becomes an unavoidable approach. Indeed, our aim interest in our study is to propose a collaborative information system for supply chain. Our proposed platform ensures cooperation and information… (More)
Radio Frequency identification (RFID) is a new technology that can identify objects without physical contact using radio frequency waves. The RFID system consists of a Tag attached in objects (people, plants, equipments, etc) and contains a unique information. The tags are identifiable by a Reader, when they're located in its interrogation range. The… (More)
In this paper we study the orienteering problem with time windows (OPTW) and the impact of relaxing the time windows on the profit collected by the vehicle. The way of relaxing time windows adopted in the orienteering problem with soft time windows (OPSTW) that we study in this research is a late service relaxation that allows linearly penalized late… (More)
order V-invexity, generalized second order V-invexity. Abstract In this paper, we consider the multiobjective nonlinear programming problem with inequality constraints. We propose a class of generalized second order V-invex functions and establish duality theorems under generalized second order V-invexity conditions.
