DEMAND FORECASTING The Context of Demand Forecasting The Importance of Demand Forecasting Forecasting product demand is crucial to any supplier‚ manufacturer‚ or retailer. Forecasts of future demand will determine the quantities that should be purchased‚ produced‚ and shipped. Demand forecasts are necessary since the basic operations process‚ moving from the suppliers’ raw materials to finished goods in the customers’ hands‚ takes time. Most firms cannot simply wait for demand to emerge and then

Systems of linear equations‚ or a set of equations with two or more variables‚ are an essential part of finding solutions with only limited information‚ which happens to be exactly what algebra is. As a required part of any algebra student’s life‚ it is best to understand how they work‚ not only so an acceptable grade is received‚ but also so one day the systems can be used to actually find desired information with ease. There are three main methods of defining a system of linear equations. One way is

Without knowing something about differential equations and methods of solving them‚ it is difficult to appreciate the history of this important branch of mathematics. Further‚ the development of differential equations is intimately interwoven with the general development of mathematics and cannot be separated from it. Nevertheless‚ to provide some historical perspective‚ we indicate here some of the major trends in the history of the subject‚ and identify the most prominent early contributors. Other

By rearranging this equation and taking logs we can form “log(Par/(1-Par))=[A]-logKA” from which we can see that plotting log (Par/1-Par)) against log [A] forms what is known as a hill plot‚ which consists of a straight line with a slope of unity. If the relationship between drug concentration and tissue response is directly proportional‚ the relationship between occupancy and response can be denoted as Y/100= Par which can be substituted into the previous equation to provide log(y/(100-y))=log[A]-log[KA]

A generalized logistic curve can model the "S-shaped" behaviour (abbreviated S-curve) of growth of some population P

The law of supply and demand describes how prices will vary based on the balance between the supply of a product and the demand for that product (Wikipedia‚ 2005). If there is a balance between the supply‚ (the availability of the product)‚ and the demand‚ (how much product the consumers want)‚ then the price for the product would be considered good. If there is an imbalance‚ the price will change. According to Adam Smith‚ the invisible hand is a self-adjusting force in the market that corrects
