Liquid preparations are particularly susceptible to microbial growth because of the nature of their ingredients. Such preparations are protected by the addition of preservatives that prevent the alteration and degradation of the product formulation [1]. The finished product release specifications should include an identification test and a content determination test with acceptance criteria and...

A methodology for the design of fuzzy control laws for tracking control of mechanical systems is described. The approach uses Lyapunov’s stability theory to formulate a class of control laws that guarantee convergence of the tracking errors to within specification limits in presence of bounded parameter uncertainties and input disturbances. The proposed methodology results in control laws that ...

Capability indices compare the actual performance of a manufacturing process to the desired performance. In practice these indices are estimated using sample data, often with quite small sample sizes. Thus, it is of interest to obtain confidence limits for actual capability index given a sample estimate. Most of the traditional methods for assessing the capability of manufacturing process are d...

The rational agency assumption limits systems to domains of application that have never been observed. Moreover, representing agents as being rational in the sense of maximising utility subject to some well specified constraints renders software systems virtiually unscalable. These properties of the rational agency assumption are shown to be unnecessary in representations or analogies of market...

Consider a production system where products are continuously manufactured and their features inspected for conformance within specification limits. If produced above or below the limits, they either subject to rework product scrapped. Optimal mean setting may be applied adjust manufacturing means influence amount of scrap produced, maximising profit. Within system, then inspecting each feature ...
