A Review of The Limits to Growth The Limits to Growth: a Report for the Club of Rome ’s Project on the Predicament of Mankind was published in 1972 predicting the future of exponential growth of economy and population in a finite world. Since 1972‚ more than 10 million copies in 37 languages have been sold by now (Gambino‚ 2011). This ambitious book is written by MIT researchers for Club of Rome which is an international think tank. The authors created a global computer model‚ Wolrd3‚ to simulate

constant service time model) assume‚ or require‚ that the arrival rate can be described by a Poisson distribution and that the service time can be described by a negative exponential distribution. Equivalently‚ we can say that the arrival and service rates must be Poisson‚ and the interarrival time and the service time must be exponential. In practice‚ one would check for this using a statistical Chi Square test: for problems provided here and in the textbook‚ assume that these distributions hold. Note

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique

Problem 1: A fast-food franchise is considering opening a drive-up window food service operation. Assume that customer arrivals follow a Poisson distribution‚ with a mean arrival rate of 24 cars per hour‚ and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive up to the service window to pay for and receive their order. Compute the following operating characteristics for each

This paper is a discussion of a debate between Julian L. Simon‚ author of The Ultimate Resource‚ and David Pimentel et al.‚ authors of the article "Impact of Population Growth on Food Supplies and Environment". The debate centers on the question: "Will the World Be Able to Feed Itself in the Foreseeable Future?" I will summarize each side’s argument‚ identify the key point over which they most basically disagree‚ and explain what I would like to know more about in order to arrive at my own position

forecasting. Planning for any event requires a forecast of the future. Whether in business or in our own lives‚ we make forecasts of future events. Based on those forecast‚ we make plans and take action. Forecasting is one of the most important business functions because all other business decision is based on a forecast of the future. Decisions such as which markets to pursue‚ which products to produce‚ how much inventory to carry‚ and how many people to hire all require a forecast. Poor forecasting results
