Designing Both Systems and Systems of Systems to Exhibit Resilience

In the world of the twenty-rst century, just about everything is going to be changing, and this change will be quite fast. According to the latest reports of the UN Intergovernmental Panel on Climate Change, we will be facing more extreme climatic events more frequently, all our systems which make use of energy and on

which we rely will be changing, and there are likely to be problems with food and water security (IPCC5-Synth-Rep 2014). This is not necessarily a benign environment; unexpected climate events will happen (heat waves, oods, severe gales, etc.), our transport systems will become electric, as will our homes, and the manufacturing systems that deliver most of our daily needs may change the most, accompanied by occasional disruptions not expected when the changes were planned.
