[ 1 ] - Monitoring Multinomial Logit Profiles via Log-Linear Models (Quality Engineering Conference Paper)
In certain statistical process control applications, quality of a process or product can be characterized by a function commonly referred to as profile. Some of the potential applications of profile monitoring are cases where quality characteristic of interest is modelled using binary,multinomial or ordinal variables. In this paper, profiles with multinomial response are studied. For this purpo...
[ 2 ] - Phase II logistic profile monitoring
In many industrial and non-industrial applications the quality of a process or product is characterized by a relationship between a response variable and one or more explanatory variables. This relationship is referred to as profile. In the past decade, profile monitoring has been extensively studied under the normal response variable, but it has paid a little attention to the profile with the ...
[ 3 ] - RTY-Based Model for Organizational Performance Measurement
Six sigma, Rolled throughput yield, Organizational performance Six Sigma is a well- established approach to improve the capability of business processes in order to gain satisfaction of customers. The performance assessment of a given process is essential to some phases of six sigma methodology. So far, different indicators are used to demonstrate the performance of a process, while many ...
[ 4 ] - Linear Profile Monitoring in the Presence of Non-Normality and Autocorrelation
In an increasing number of practical situations, the quality of a process or product can be effectively characterized and summarized by a profile. A profile is usually a functional relationship between a response variable and one or more explanatory variables which can be modeled frequently using linear or nonlinear regression models. In this paper, we study the effect of non-normality on pro...
[ 5 ] - Application of Analytic Network Process in Selection of Six-Sigma Projects
This research aims at presenting a fuzzy model to evaluate and select Six-Sigma projects. For this purpose, a model of fuzzy analytic network process (ANP) was designed to consider the relation and mutual impact among the factors. In order to evaluate the projects, nine sub-criteria were considered which were classified into three categories of business, finance and procedural ones. Also to co...
[ 7 ] - پایش بیماری، کاربردی جدید از پایش آماری پروفایل ها – مورد کاوی: بیماری ریوی
The application of statistical process control methods to health care is facing an expansion in the recent days. In some statistical process control applications, quality of a process or product is characterized by a relationship between two or more variables which is referred to as a "profile". Profile monitoring method plays a very important part in statistical control process. Unfortunatel...
[ 8 ] - ترکیب ماشین بردار پشتیبان و مدل‌های پیش آموزش دیده‌ی شبکه عصبی کانولوشن به منظور طبقه‌بندی تومورهای مغزی در تصاویر ام‌آر‌آی
به دلیل محل رشد تومورهای مغزی در سر انسان، معمولا احتمال مرگ بر اثر این تومورها، شش برابر بیشتر از تومورهای دیگر است. سیستم‌های کامپیوتری را می‌توان برای کاهش تجویز درمان‌های نامناسب و کمک به متخصصان در تشخیص این بیماری استفاده کرد. در این مقاله از یک الگوریتم جدید به‌منظور تشخیص تومورها در 900 تصویر ام‌آر‌آی استفاده شده است. این الگوریتم مشتمل بر چهار فاز اصلی است که در فاز اول بعد از ورود داد...
[ 9 ] - مدل‌سازی استراتژی‌های نفوذ در بازار با استفاده از شبیه‌سازی مبتنی بر عامل
پیش‌بینی نتایج معرفی محصول یا برند جدید به بازار، با توجه به هزینه‌های بالای توسعه محصول و تأثیر عمیق شکست احتمالی آن روی آینده سازمان، از دهه‌های گذشته مورد توجه بسیاری از محققان و مدیران حوزه بازاریابی و کسب و کار بوده است. در این میان، وجود عوامل متعدد و متغیر که رفتار بازار را در واکنش به ورود یک محصول یا برند جدید شکل می دهند، پیش بینی را دشوار و دستیابی به مدلی مناسب برای تصمیم گیری درست ...
[ 10 ] - A Statistical Method for Sequential Images – Based Process Monitoring
Today, with the growth of technology, monitoring processes by the use of video and satellite sensors have been more expanded, due to their rich and valuable information. Recently, some researchers have used sequential images for image defect detection because a single image is not sufficient for process monitoring. In this paper, by adding the time dimension to the image-based process monitorin...
[ 11 ] - Identifying patterns of the dynamic credit risk of banks customers and financial institutions: case study- an Iranian bank
Credit risk assessment has always been one of the most important concerns of banks. Widely used models such as financial models have been used to assess credit risk so far. But increasing non-performing loans indicates that today these models cannot assess the credit risk of customers. Inconstant and uncertain environmental, social and political factors affect customer behavior and change custo...
