This article investigates a Cautious Minimum Variance (CMV) control approach for controlling industrial process variability when the model parameters are estimated from data and subject to uncertainty. CMV control has a number of advantages over traditional robust control methods. It incorporates probabilistic, as opposed to deterministic, measures of parameter uncertainty, which are more consi...

in statistical quality control a very widely used measure is average run length (arl) which may be worked out by different methods like integral equation, approximations, and monte carlo simulations. the arl measure and the other related measures are of major significance in every type of production process. an omission in its computation (and hence its related measures such as extra quadratic ...

This paper presented a mixed integer programming for integrated scheduling and process planning. The presented process plan included some orders with precedence relations similar to Multiple Traveling Salesman Problem (MTSP), which was categorized as an NP-hard problem. These types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...

When designing a system, first define what you need to accomplish. Will the system need to both control and monitor? Which unique business processes do you want to integrate into the system, for example, a purchasing database or quality tracking database? Identifying the integral processes up front is important to properly architect the system. Choosing the right tools can help you build common...

Manufacturing is a global activity that started during the industrial revolution in the late 19th century to cater for the large-scale production of products. Since then, manufacturing has changed tremendously through the innovations of technology, processes, materials, communication and transportation. The major challenge facing manufacturing is to produce more products using less material, le...

Third generation wireless systems can simultaneously accommodate flow transmissions of users with widely heterogeneous applications. As radio resources are limited, we propose an admission control rule that protects users with stringent capacity requirements (“streaming traffic”) while offering sufficient capacity over longer time intervals to delay-tolerant users (“elastic traffic”). Using tim...

n increasing number of software process and product standards emphasize the need for measurement. ISO 9001, for example, provides guidance for monitoring and controlling product and process characteristics during both production and installation. 1 However, standards provide little guidance as to what exactly users should measure and how to use the results to support the development of high-qua...

A control monitoring package can be designed to take advantage of the powerful technology in a PID optimization package. With an integrated optimization package, during normal analysis of plant data, the monitor is constantly scanning the data for special data features. These data features allow model identification and control performance calculations on a continual basis. The monitor is scann...

An increasing number of firms are marching to the drumbeat of business process redesign (BPR), alternatively called reengineering. The term reengineering may be new, but the idea of process redesign is familiar to most engineers involved in logistics and production control. Just-in-time (JIT), Total Quality Management (TQM), Flexible Manufacturing Systems (FMS), Computer Integrated Manufacturin...
