CHAPTER I THE PROBLEM: rationale and background Introduction There has been no era that can be read in the history books that connecting mankind through internet has made its greatest significance than it is today. The Internet‚ sometimes called simply “the Net‚” is a worldwide system of computer networks – a network of networks in which users at any one computer can‚ if they have permission‚ get information from any other computer (and sometimes talk directly to users at other computers)

suggesting that we have not found and exploited all of the pattern in the demand data. This in turn would suggest that the forecasting procedure being used is inappropriate. For example‚ suppose our forecasting system always gave us a forecast that was on average ten units below the actual demand for that period. If we always adjusted this forecast by adding ten units to it (thus correcting for the bias)‚ the forecasts would become more accurate as well as more unbiased. Logistics managers sometimes prefer

Measure of Central Tendency The following are the important measures of Central Tendency a)Mean b) Median and c) Mode Mean can be classified as three types: i) Arithmetic mean ii) Geometric mean iii) Harmonic mean. Measure of Central Tendency An average (mean) is a single value which is considered as the most representative or typical value for a given set of data. Such a value is neither the smallest or the largest value‚ but is a number whose value is somewhere in the middle of the group. Measure
