- The analyst in the Dorben Company wishes to assign a number of like facilities to an operator based on minimizing the cost per unit of output. A detailed study of the facilities revealed the following: Loading machine standard time = 0.30 minutes Unloading machine standard time = 0.25 minutes Walk time between two machines = 0.09 minutes Operator rate = $12.00 per hour Machine rate (both idle and working) = $18.00 per hour Machine cycle time = 1.55 minutes TEC = The Expected Cost a) With your initial estimation, how many machines can be serviced exactly?(please keep a non-integer with three decimal places) b) How much is your TEC per piece if the operator has idle time? (please keep three decimal places) c)How much is your TEC per piece if the machine has idle time? (please keep three decimal places) d) How many of these machines should be assigned to each operator?(please write down a numerical number)A car repair shop has 3 stages of process serially to performcare of its customers' cars.

What is System Reliability now? Is able to meet System standardsReliability workshop? Explain your answerUsing signavio or any PBM tools and must Use pool and lane and object. Model the following business process at a supplier. After a supplier notifies a retailer of the approval of a purchase order, the supplier can receive an order confirmation, an order change, or an order cancelation from the retailer. It may happen that no response is received at all. If no response is received after 48 h, or if an order cancelation is received, the supplier will cancel the order. If an order confirmation is received within 48 h, the supplier will process the order normally. If an order change is received within 48 h, the supplier will update the order and ask again the retailer for confirmation. The retailer is allowed to change an order at most three times. Afterwards, the supplier will automatically cancel the order.

- For Problem 19.27 , determine the probability (assuming normal distribution) that a car would need engine maintenance between 70,000 and 90,000 kilometers.Best Buy sells three models of computers, the Litepro, Medpro, and Heavypro, and they are managed by three independent product managers. Annual demands for the three products are as follows: DL = 120,00 units for the litepro, DM = 1,200 units for the Medpro, and DH = 120 units for the Heavy pro. Assume that each model costs Best Buy $500. A fixed transportation cost of $4,000 is incurred each time an order is delivered. For each model ordered and delivered on the same truck, an additional fixed cost of $1,000 is incurred for receiving and storage. Best Buy incurs a holding cost of $100 per year. Evaluate the lot sizes that each Best Buy manager should order if lots for each product are ordered and delivered independently. Also evaluate the annual cost of such a policy. (Use the EOQ formula.)(a) A very important component of a system has a mean time between failures of 100 hr and a mean time to repair of 10 hr. Determine the inherent availability of the system.
