According to the characteristics of industrial robots, user-customized configuration design pattern is showing to achieve rapid development of industrial robotics. In this paper, the definition of usercustomized configuration design pattern is determined. The implementation approach of this pattern is given through introducing what role industrial robot stakeholders including suppliers, manufac...

In this paper we focus on the modeling and simulation of a distribution service network (DSN) for urban rail transit hub (URTH). Firstly, using the method of complex networks, the concept of DSN is proposed. Secondly, a model of DSN is formulated which consists of: i) a distribution entity topology network, ii) a distribution transport function network and iii) a distribution service function n...

با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

Ship maintenance requires the use of a lot resources, and schedule risk caused by resource factors is an important reason for long time easy delay projects. This paper adopts system dynamics theory to analyze dynamic relationship between activity allocation factors, establishes assessment model. Use anylogic software simulate implementation process activities, effectively mutual influence chang...

At the end of 2019, COVID-19 outbreaks occurred one after another in countries worldwide. Managing outbreak efficiently and stably is an essential public health issue facing In this paper, based on SEIR model, we propose a SCEIR model that incorporates close contacts (C) self-protectors (P). Firstly, epidemic data China, USA, Italy are predicted compared with actual data. Secondly, sensitivity ...
