A chance-constraint multi-objective model under uncertainty in the availability of subassemblies is proposed for scheduling in ATO systems. The on-time delivery of customer orders as well as reducing the company's cost is crucial; therefore, a three-objective model is proposed including the minimization of1) overtime, idletime, change-over, and setup costs, 2) total dispersion of items’ deliver...

Background and aim: Afterpain is a common phenomenon after vaginal delivery. Any factor that causes a delay in the process of uterus sub involution and consequently returning its size to pre-pregnancy status could affect the severity of afterpain. This study aimed to investigate the factors related to afterpain in multiparous women delivered in 17-Shahrivar Hospital, Mashhad, Iran.  Methods: In...

one of important problems in supply chains management is supplier selection. in a company, there are massive data from various departments so that extracting knowledge from the company’s data is too complicated. many researchers have solved this problem by some methods like fuzzy set theory, goal programming, multi objective programming, the liner programming, mixed integer programming, analyti...

Quality of Service (QoS) in Wireless Sensor Networks (WSNs) is a challenging area of research because of the limited availability of resources in WSNs. The resources in WSNs are processing power, memory, bandwidth, energy, communication capacity, etc. Delay is an important QoS parameter for delivery of delay sensitive data in a time constraint sensor network environment. In this paper, an exten...

Multihop routing is the advanced technology in wireless Networks. Multipath routing protocols for MANET are deemed superior over conventional single-path routing as the former to reduce end to end delay, increase consistency and provide toughness. Quality of Service (QoS) is an essential feature of networks. One of the main problems in Ad-hoc networking is the delivery of data packets to the no...

objective assessment of risk predictors for adverse neurodevelopmental outcome at 1 year of age in term and near-term infants. material & methods this case-control study was a representative sample of infants from different health-care centers of north and east of tehran. the association between risk factors and delayed motor development (developmental quotient below 70 indicating a significant...

Real-time routing is a basic element of closed-loop, real-time sensing and control, but it is very challenging due to dynamic, uncertain link/path delay. A basis of real-time routing is determining probabilistically guaranteed path delays, but this problem is NP-hard and it may well have to be solved by resource-constrained devices in a distributed manner; the highly varying nature of link/path...

Wireless data access for nomadic users is predicted to be a major growth direction for the future Internet. However, no single existing wireless technology fits all user requirements at all times. Instead, several overlaying wireless networks can provide best possible data delivery service. Nomadic users can run interactive, conversational, streaming, and background applications that rely on en...
