Interpretation:
Theten year reliability of D. T.’s current satellite design.
Concept Introduction:
An overall consistency of a measure is known asreliability. If the measure produces similar results under consistent conditions then it is called a high reliability.

- A large city in the mid-West needs to acquire a street-cleaning machine to keep its roads looking nice year-round. A used cleaning vehicle will cost $85,000 and have a $20,000 market (salvage) value at the end of its five-year life. A new system with advanced features will cost $150,000 and have a $40,000 market value at the end of its five-year life. The new system is expected to reduce labor hours compared with the used system. Current street-cleaning activity requires the used system to operate 8 hours per day for 20 days per month. Labor costs $50 per hour (including fringe benefits), and MARR is 12% per year.]arrow_forward5. Meg Jones, the CEO of Ajax Computer Company, and Brad Smith, its Director of Operations, had been discussing how to increase the firm’s production of the company’s flagship XR58. The XR58 was particularly important because it sold 12,500 of them in the most recent year for $950, at a gross margin of 55%. After a lot of discussion, they decided to pursue an incentive system designed to increase production by 12% in the next year. After Brad discussed this possible incentive with the production team, the team determined that it could increase production by this amount without adding any more people or equipment. They believed they could accomplish this improvement primarily through process redesign. To incent them to do the hard work of process improvement, Brad told the team that it would receive 25% of the increased profits if it met the new production goal.

It consists of three major components: transport and storage equipment, training personnel, and efficient management procedures. The majority of the vaccine in the cold chain is typically maintained at a temperature of 2-8°C. Maintaining cold chain integrity is extremely important for healthcare product manufacturers. Especially for the vaccines, improper storage, and handling practices that compromise vaccine viability prove a costly, time-consuming affair. Vaccines must be stored properly from manufacture until they are available for use. Any extreme temperatures of heat or cold will reduce vaccines potency; such vaccines, if administered, might not yield effective results or could cause adverse effects.

- A company has two warehouses that store different products: Tashkent and Samarkand. When an order is received, it is distributed across these warehouses: if some of the relevant products are maintained in Tashkent, a sub-order is sent there; likewise, if some relevant products are maintained in Samarkand, a sub-order is sent there.

Mr Peter has recently joined the firm as the account payable clerk. Miss Emma is the accounting department head, and she is concerned about the cash disbursement system. Therefore, she has asked Mr Peter to analyse the firm's cash disbursement system and identify the internal control weaknesses from the system. Following is the description of the cash disbursement system. In the temporary file, the account payable clerk receives the supplier's invoice and reconciles it with the purchase order. The accounts payable clerk records the purchase in the purchases journal from the clerk's computer terminal and records the liability by adding a record to accounts payable subsidiary ledger. The clerk then updates the inventory control and accounts payable control accounts in the general ledger. The purchases order and invoice are later filed in the department.
