Linear regression tools have applied in many organisations to forecast for the observed variables. The military may want to determine whether there is a relationship between warring period and weapons use. To do so, the observed data is analysed and the simple line equation is used.The simple regression analysis can be determined by plotting a graph using the same variable to obtain the line of best fit. This can be then be used to forecast on future needs of weapon acquisition for the military. The relationship between the period the war takes the higher the number of weapons needed. The relationship is linear. This model works best when there are two variables under consideration.Scatter diagrams are used to analyze the relationship between two variables. The variables are plotted in the graph and the line of best fit cuts through the majority of the variables. As the case of simple regression analysis, the scatter diagrams are used for predicting variables and relationship between variables is also assessed.Inventory control allows managers to determine the lead time i. the time between the supply of raw materials and production time. The lower the lead time the more effective the company operates because it is will always be on time in production and meeting the consumers demand (Donald, 2003).Just in time module is applied when the production is made on delivery of raw materials.
