An organization as big as Unilever (1975 sales were Pound 7000 million) needs to consider the balance of interest between shareholders, employees, customers, government and the environment. Many routine decisions are computerized and no longer of scientific interest. The talk will be concerned with some more complex problems. Decision trees are being used on investment and withdrawal problems. Systems analysis helps us to study the long-term effects of effluents on wild life in rivers. We have the world's largest private telecommunications network so that managers can have access to current information and we have computer based financial models to enable us to explore the effects of decisions on cash and profit flows.
