Clustering is one of the main methods of data mining. K-means algorithm is one of the most common clustering algorithms due to its efficiency and ease of use. One of the challenges of clustering is to identify the appropriate ...

Earthquake is common natural disaster in Iran, often accompanied by huge damages, losses and casualties. Therefore, focusing on earthquake response management, and improving its effectiveness is an important issue for the ...

The present paper examines the problems of stable and robust scheduling under disruptions with uncertain processing times. In order to handle such problems, in addition to exact solution approaches, a general predictive ...

Resource constrained project scheduling problem with multiple routes for flexible project activities (RCPSP-MR) is a generalization of the RCPSP, in which for the implementation of each flexible activity in main structure ...

In this paper, a flexible lifetime distribution with increasing, decreasing, increasing-decreasing-increasing and bathtub hazard function, called New Family of Kies Burr III (NFKBIII) distributions is proposed. The density ...

In this paper, a supply chain network system is viewed as a serial-parallel multistage process; and the application of a change point control chart based on likelihood ratio is explored to monitor this system. Firstly, ...

Under conditions of consumer panic buying, satisfying demand with the available products is a complex problem. In reality, most retailers accept alternative products during panic situations. This study considers the case ...

s an effective method for evaluating efficiency, the cross-efficiency evaluation method has been widely used to assess the performance of decision-making units (DMUs). However, the non-uniqueness of optimal weights problem has ...
