Abstract: This paper studies multi-product production manufacturing systems with in-line quality control. Quality control is carried at inspection stations located within a production line. Quality control has an impact on performance of the system: throughput decreases and resource utilization increases. Production lines are modeled as a multi-product Open Jackson Network, where stochastic cha...
Inspection planning is an important activity in process industries, and one of the key tools used for such planning is the risk based inspection (RBI) methodology. The RBI is commonly used in planning of inspections for static mechanical equipment, in particular piping networks. The inspections are prioritized based on risk, expressed as expected values, integrating the likelihood and consequen...
The purpose of this article is to propose both state and time-dependent preventive maintenance policy for a multi-state deteriorating system, which is equipped with inspection equipment(s) connected to a computer center. After the system being identified as state x at nd through computation by the computer center after inspection (or measurement) via equipment(s), one maintenance action with th...
Inspection engines that can inspect network content for application-layer information are urgently required. In-depth packet inspection engines, which search the whole packet payload, can identify the interested packets that contain certain patterns. Network equipment then utilizes the searching results from the inspection engines for application-oriented management. The most important technolo...
We have developed a laser ultrasonic visualization(LUV) equipment. It can be used to study the ultrasound propagation in an arbitrary-shaped object, and also be used to the nondestructive inspection of materials and structures. The LUV equipment consists of the hardware and the software. The hardware consists of a pulsed laser, a scanning mirror (galvanometer scanner), an ultrasound sensor, a l...
In this paper, we focus on a continuously deteriorating critical equipment which its failure cannot be measured by cost criterion. For these types of systems like military systems, nuclear systems, etc it is extremely important to avoid failure during the actual operation of the system. In this paper we propose an approach which constrains failure probability to a pre-specified value. This valu...
