The home appliance department in a large department store is using a (Q, R) system to control the replenishment of a model of FM radio. The store sells an average of 12 radios each week. Weekly demand follows a normal distribution with variance 30. (Assume that there are 52 weeks in a year.) The store pays $20 for each radio, which it sells for $85. Fixed order cost is $30 per order. The accounting department recommends a 20% interest rate for the cost of capital. Storage costs are 3% and breakage 2% of the purchasing cost of each item. If a customer demands the radio when it is out of stock, the customer will generally go elsewhere. Loss-of-goodwill costs are estimated to be about $25 per radio. Order lead time is 13 weeks. (The penalty cost includes loss of profit and loss of goodwill.) Find the optimal values of (Q, R) based on the penalty cost. What are the values for Q and R if the stock-out cost is replaced with a 95% Type 1 service level?
Critical Path Method
The critical path is the longest succession of tasks that has to be successfully completed to conclude a project entirely. The tasks involved in the sequence are called critical activities, as any task getting delayed will result in the whole project getting delayed. To determine the time duration of a project, the critical path has to be identified. The critical path method or CPM is used by project managers to evaluate the least amount of time required to finish each task with the least amount of delay.
Cost Analysis
The entire idea of cost of production or definition of production cost is applied corresponding or we can say that it is related to investment or money cost. Money cost or investment refers to any money expenditure which the firm or supplier or producer undertakes in purchasing or hiring factor of production or factor services.
