Datamodellering og simulering

Videregående kvantitative metoder behandler avancerede emner inden for statistisk modellering af samfundsvidenskabelige fænomener primært med udgangspunkt i data på individniveau. Emnerne i de enkelte kapitler er udvalgte, så de er dækkende for de typer af data, som man oftest vil støde på i samfundsvidenskaberne.De teoretiske overvejelser i kapitlerne illustreres af grundige empiriske illustrationer fra det sociologiske, politologiske, økonomiske eller socialmedicinske område. Vægten er således lagt på anvendelsen af teorien og vil sætte læseren i stand til trinvist at løse et givet modelleringsproblem.Videregående kvantitative metoder henvender sig særligt til samfundsvidenskabelige forskere, master- og ph.d.-studerende, som med baggrund i en viden om elementær statistik har brug for at opruste sig på avancerede emner inden for området, men kan også anvendes af bachelorstuderende, som følger kvantitative fag, der ligger ud over basal kvantitativ metode.

Enterprise risk management has always been important. However, the events of the 21st Century have made it even more critical. The top level of business management became suspect after scandals at ENRON, WorldCom, and other business entities. Financially, many firms experienced difficulties from bubbles. The problems of interacting cultures demonstrated risk from terrorism as well, with numerous terrorist attacks, to include 9/11 in the U.S. Risks can arise in many facets of business. Businesses in fact exist to cope with risk in their area of specialization. Financial risk management has focused on banking, accounting, and finance. We have discussed several aspects of risk, to include information systems, disaster management, and supply chain perspectives. The bulk of this book is devoted to presenting a number of operations research models that have been (or could be) applied to enterprise supply risk management, especially from the supply chain perspective.
