This paper deals with phase II, univariate, statistical process control when a set of in-control data is available, and when both the in-control and out-of-control distributions of the process are unknown. Existing process control techniques typically require substantial knowledge about the in-control and out-of-control distributions of the process, which is often difficult to obtain in practic...

The earned value method is an internationally recognized project management tool for tracking progress on projects. It periodically calculates the earned value of their completed project tasks, discovers the schedule and cost variances of the projects from the baseline, and thus helps to timely take measures to adjust and control the projects. Despite its popularity, it has not been widely appl...

In many processes in real practice at the start-up stages the process parameters are not known a priori and there are no initial samples or data for executing Phase I monitoring and estimating the process parameters. In addition, the practitioners are interested in using one control chart instead of two or more for monitoring location and variability of processes. In this paper, we consider a s...

This paper deals with the simultaneous statistical process control of several Poisson variables. The practitioner of this type of monitoring may employ a multiple scheme, i.e. one chart for controlling each variable, or may use a multivariate scheme, based on monitoring all the variables with a single control chart. If the user employs the multivariate schemes, he or she can choose from, for ex...

Planning and controlling costs time is part of the overall construction project management. In addition to assessment in terms quality, achievement a can also be assessed cost time. The that have been incurred spent completing job must measured continuously for deviations from plan. presence significant indicates poor With existence performance indicators this allows preventive actions so imple...

The earned value method (EVM) is an internationally known technique for project management that emphasizes the control of cost performance and duration, thus allowing trends to be identified during execution warning manager variances may affect so they can take necessary corrective measures. In this research, finished projects a construction company in city Cuenca, Ecuador, were assessed. EVM w...

A complex electrical engineering project, Dronenet, is a design and system integration of four major subsystems: an unmanned aerial vehicle (UAV), a control terminal for the UAV, a mobile UAV carrier, and a control terminal for the mobile UAV carrier. Dronenet has a unique regenerative charging system based on the design of a Bedini motor to extend the duration of Pb and LiPo batteries. This pr...

background: assessment of national children's growth indicated a high prevalence of growth failure among them. many previous projects have studied the children’s growth & nutrition status but most of them have not evaluated. the aim of this study was to evaluate the mothers' participation project after passing two years. methods: in this descriptive and summative evaluation study, 90 mother and...
