یکی از موضوعات مورد بحث در مسائل بهینه سازی جانمائی مسئله استقرار و تخصیص می باشد. در حالت کلی در این مسئله محل استقرار بهینه و تخصیص بهینه چند خدمت دهنده برای تامین تقاضای چندین مشتری باید تعیین شود. این مسئله به دلیل طبیعت نامحدب آن معمولا دارای بهینه های محلی متعددی بوده و اسنفاده از روشهای دقیق ریاضی به تنهایی برای حل این مسائل بسیار پرهزینه و غیرممکن است . لذا همانگونه که در مقالات تحقیقی ...

This study proposes the model for interpolating time series to use them  to forecast effectively for future. This model is established based on the improved fuzzy clustering analysis problem, which is implemented by the Matlab procedure. The proposed model is illustrated by a data set and tested for many other datasets, especially for 3003 series in  M3-Competition data. Comparing  to the exist...
