Methodology | Student Resources | Variables. f you are on this path, you have decide that the overall design of your project will take a quantitative approach. As described before in Elements of the Proposal, there are four main types of quantitative research designs. You will need to decide which one is most appropriate for your research questions. While there are many different investigations that can be done, a study with a quantitative approach generally can be described with the characteristics of one of the following four types:
Performance Based Contracting. From Wikipedia, the free encyclopedia. Performance Based Contracting (PBC), also known as performance-based logistics (PBL) or performance-based acquisition, is a product support strategy used to achieve measurable performance outcomes, for example in the defense industry.
The term SCADA (Supervisory Control and Data Acquisition) usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas (anything from an industrial plant to a nation). Most control actions are performed automatically by RTUs or by PLCs.ata acquisition begins at the RTU or PLC level and includes meter readings and equipment status reports that are communicated to SCADA as required. Data is then compiled and formatted in such a way that a control room operator using the HMI can make supervisory decisions to adjust or override normal RTU (PLC) controls.
