In theoretical economics, investment means buying (and therefore producing) capital goods - not being consumed but being used in future production. Examples include building railroads, or factories, cleaning the land, or allowing yourself to go to college. Strictly speaking, investment in formula GDP= C + I + G + NX is also part of gross domestic product. In that respect, the function of investment is divided into non-residential investments (such as factories, machinery, etc.) and residential investment (new homes). The correlation between I = (Y, I) is known to have a close relationship with income and interest rates. Higher incomes would boost higher investment, but higher interest rates would discourage investment because it would be more expensive to borrow. Even if companies choose to use their own funds to invest, interest rates represent the opportunity cost of investing in those funds rather than the interest that will lend out. As we strive to earn an incredible living and pay our charges, there are also crooks who generate a full time income by robbing from unsuspecting victims. Thus, we need to always be on guard from such individuals by securing our private data and making sure that they're not taken from us and useful for crooks' advantages. Having determined the sequence that work well is usually to be tackled in, some operations have to have a detailed timetable showing at what time or date jobs should start so when they must end ' this really is scheduling. Schedules are familiar statements of volume and timing in several consumer environments. For example, a bus schedule demonstrates more buses are put on routes at more frequent intervals during rush-hour periods. The bus schedule shows enough time each bus is because of go to each stage in the route. Schedules of training are widely-used in operations where some planning must be sure that customer demand is met. Other operations, including rapid-response service operations where customers arrive in an unplanned way, cannot schedule the operation in the short-term sense. They can only respond at some time demand is positioned upon them. The scheduling activity is one in the most complex tasks in operations management. First, schedulers must deal with several unique kinds of resource simultaneously. Machines will have different capabilities and capacities; staff can have different skills. More importantly, the quantity of possible schedules increases rapidly as the number of activities and processes increases. This sharp reversal contrasts with the flattening of the previous yield curve.
