We consider a berth allocation and quay crane assignment problem (BACAP) to concurrently optimize the two objectives: operation cost and customer satisfaction. We formulate the multi-objective BACAP as a mixed-integer nonlinear programming model. The latter objective is based on vessel departure tardiness which is measured from the perspective of behavioral operations research. A multi-objective genetic...
Multi-criteria human resource allocation involves deciding how to divide human resource of limited availability among multiple demands in a way that optimizes current objectives. This paper aims to solve the multi-criteria optimal allocation of human resources issues using multi-objective particle swarm optimization (MOPSO). In this paper, we tackled this problem via a multi-objective decision-making...
With the development of the global business and logisticspsila a container terminal (CT) system becomes more and more busy. Therefore, the available resources in the sea port get scarcer than before. In order to increase the operating efficiency of CT system, the resources planning problem has become a critical issue in the fields of operations research and logistics. In this paper, we introduce the...
The weapon-target assignment (WTA) problem is a fundamental problem arising in defense-related applications of operations research. The WTA problem can be formulated as a nonlinear integer programming problem and is known to be NP-complete. We present firstly a technique founded on the use weapon cell, which enables one-to-many mapping about weapon-target to become one-to-one mapping. Next, we introduce...
