This paper deals with a problem of minimizing total weighted tardiness of jobs in a real-world single batch-processing machine (SBPM) scheduling in the presence of fuzzy due date. In this paper, first a fuzzy mixed integer linear programming model is developed. Then, due to the complexity of the problem, which is NP-hard, we design two hybrid metaheuristics(More)
Data Envelopment Analysis (DEA) is a non-parametric technique for measuring the efficiency of Decision Making Units (DMUs) with multiple inputs and outputs. DEA for a large dataset with many input/output variables and/or many DMUs would need huge computer resources in terms of memory and CPU time. This paper proposed an Electromagnetism Algorithm (EA) for(More)
In this paper, we study a flow shop batch processing machines scheduling problem. The fuzzy due dates are considered to make the problem more close to the reality. The objective function is taken as the weighted sum of fuzzy earliness and fuzzy tardiness. In order to tackle the given problem, we propose a hybrid electromagnetism-like (EM) algorithm, in(More)
