<p>Sorry it took me a while to get back to your questions. Summer vacation with the family and all...</p>
<p>New topics in OR: There are several broad fields of new work. One is in the area of 'computational' science. This means, normally, simulations of systems or processes that are too complex for a mathematical, closed-form solution. There is computational statistics -- the determination of underlying stats using a simulation. There is computational social science, which uses agent-based models and simulations to evaluate system performance and behavior when the interactions between individual elements is important to overall changes in state. OR can be part of an analysis of social network theory, which helps in marketing, technology development, land use, or, in the military domain, counterinsurgency. </p>
<p>Moving toward more traditional techniques applied innovatively, there is a lot being done to help understand supply chain and logistic decisions. OR helps model risk and describe, for the decision-maker, the impact of various courses of action. </p>
<p>There are a lot of research processes that use OR to operate more efficiently. OR methods can help design experiments so that the best conclusions can be reached with the least amount of research or the fewest trials. </p>
<p>Large organizations such as the military often use OR experts for long-term force structure decisions. And, manpower planning is an important process that needs people to do quantitative analysis. OR experts often participate and sometimes lead organizational reform efforts within the company. </p>
<p>The optimization tools can be used by financial decision makers and senior executives for 'balance of investment' or 'portfolio management' decisions. This is not always choosing the right stocks to buy. It can be a decision by a manufacturer to open or close a particular line of business. </p>
<p>While this might be the province of business managers or MBAs, I've seen such people fail completely due to a lack of quantitative and statistical firepower. Often, the MBA might be the consultant, but the real work is done by an OR practitioner or a statistician behind the scenes.</p>
