Using an Evolutionary Algorithm in Multiobjective Geographic Analysis for Land Use Allocation and Decision Supporting

Usually, allocation of resources is an optimization problem which involves a variety of conflicting economic, social, and ecological objectives. In such a process, advanced geographic analyst tool for manipulation of spatial data and satisfaction of multiple objectives is essential to the success of decision‐making. The present research intends to demonstrate the application of a multiobjective optimization method based on NSGA‐II 1 (we call it HNSGA‐II), along with Geographical Information System (GIS) 2 to select suitable sites for the establishment of large industrial units. Having defined the elements of HNSGA‐II for the site selection of industrial units, the method is tested on the data of Zanjan province, Iran, as the case study. The results showed that the proposed approach can easily find a variety of optimized solutions, giving the decision‐makers the possibility to opt for the most propitious solution. Using this method, the achievement level regarding each objective function can be studied for any of the nondominated solutions.     

Cerita Kentrung Sebagai Warisan Tradisi

Kentrung stories as a traditional heritage

Kentrung stories are performed orally by a story‐teller (dhalang kentrung), who is accompanied on simple instruments. Some stories take several nights to complete. The story is mostly spoken and in prose, but is interspersed with sung metrical passages not essential to the plot. Kentrung is performed on special occasions, including circumcisions, marriages, and ruwatan (ceremonies to avert disaster). A trainee dhalang learns the story's framework and certain passages by heart, but most of the story is not memorized verbatim. Hence variations occur between a dhalang's performance and his pupil's, and between different performances by one dhalang. Some pupils learn by imitation while working as servants for the dhalang, others while acting as his instrumental accompanists, and others receive direct teaching (this, however, is confined to members of the dhalang's family).
