Gross Development Value (GDV)

1. Gross Development Value (GDV) is the forecast revenue or sale that is anticipated from the completed development scheme.

2. This calculation is effectively whether a development has, or will, turn a profit at completion. 

3. Profit on Gross Development Value is calculated by assessing the cost of development versus the sale of the completed properties to create a total profit value which is then calculated into percentage terms.

SCADA - Part 2- SCADA vs PLC vs DCS and Exploring PLC-SCADA Solutions

1. Currently there are two main stream types of control systems – PLC-SCADA and Distributed Control Systems (DCS).

2. DCSs were traditionally used to control large processes, while PLC systems were used to control machines. Since the introduction of PC Windows-based SCADA systems and Ethernet networks, the dividing lines between DCS and PLC-SCADA systems have become blurred.

SCADA - Part 1 - Supervisory control and data acquisition Introduction

 1. SCADA, or supervisory control and data acquisition, is a system comprised of hardware and software components used to monitor and control industrial processes.

2. With a SCADA system, manufacturers are able to collect and analyze real time production data, monitor and manage alarms, and program automatic control responses triggered by certain events or system parameters.

3. There are different types of SCADA systems that can be considered as SCADA architectures of four different generations:

- First Generation: Monolithic or Early SCADA systems
- Second Generation: Distributed SCADA systems
- Third Generation: Networked SCADA systems and
- Fourth Generation: Internet of things technology, SCADA systems

Rail and Air Co-operates to Provide Seamless Service

1. The Dutch carrier is taking more concrete steps towards a greener future with the announcement of a high-speed rail replacement service for one of its popular short-haul routes between Amsterdam Airport Schiphol (AMS) and Brussels (BRU).

2. KLM has teamed up with NS Dutch Railways and French-Belgian high-speed train operator Thalys to promote the service to connecting passengers who would otherwise take what Business Traveller dubbed Europe’s most expensive (on a per-mile basis) flight.
