resistance R1 with source pressure P1. F2 is output flow through resistance R2 and flowing out at pressure P2. As the flows into and out of the tank are both influenced by the tank pressure‚ both flow resistances affect the time constant. A typical control problem would be to manipulate one flow rate (either in or out) to maintain a desired drum pressure. Variables: Controlled variable: P Manipulated variable: F2 Disturbance variable: F1 Here we develop a model that describes how the tank pressure

Process Improvement Plan The first week of class a flowchart was created to show the process of my daily routine from getting up in the mornings to arriving to work. The purpose of creating the flowchart was to identify a more effective way to utilize time each day‚ also to identify potential reasons that may hinder the process and to maximize limited time that is available daily. The statistical process control plan is used to ensure that time management and operations will flow as effectively

Controlling measures the deviation of actual performance from the standard performance‚ discovers the causes of such deviations and helps in taking corrective actions. According to Brech‚ controlling is a systematic exercise which is called as a process of checking actual performance against standards or plans with a view to ensure adequate progress and also recording such experience as is gained as a contribution on to possible future needs.
