F = 12,000 + 40M
Where: F = Total monthly factory costs, and
M = Machine hour per month.
Regression sum of squares = 41,437,500

(a) Explain the role of strategic planning in performance management. (3 marks)
(b) Amadi hospital is organised into separate medical units offering specialized nursing care services such as maternity and pediatric services. Information for pediatric unit for 2020 has just been availed. Revenue earned was Sh. 4.400,000 and patients were charged a fee of Sh.2,000 per patient day for nursing care. The cost of running the unit consists of variable costs on catering and laundry services. These are based on the number of patient days spent in the hospital, direct staffing costs established from personnel requirements applicable to particular levels of patient days and allocated fixed costs such as security and administration that are based on bed capacity. The bed capacity currently stands at 80 beds.
The number of beds available for occupation is regarded as bed capacity and which is agreed and held constant for the whole year. There was an agreement that a bed capacity of 80 would apply to the pediatric for the 365 days of the year.
The table below shows the variable cost information in the pediatric unit based on patient days in 2020:
Catering                     4,500,000
Laundry                     1,500,000
Pharmacy                  5,000,000

Staffing cost: Each specialty recruits its own nurses, supervisors and assistants. The staffing requirements for the pediatric unit is on the actual patient days.
Patient days p.a                         Supervisors                Nurses                  Assistants
Upto 20,500                                                 4                             10                             20
20,501 – 23,000                                         4                              13                             24

As a consequence, in the 2021 budget, an increase in bed capacity has been agreed. 20 extra beds will be contracted for the whole year. It is assumed that the 100 beds will be fully occupied for the 100 days. An increase of 10% in employment costs due to a rise in wage rate is expected to occur in 2021 for all personnel. The revenue per patient day, all other cost factors and the remaining occupancy will remain the same as 2020.
(i) Determine the actual number of patient days, bed occupancy percentage, net profit or loss and break even number of patient days for the year 2021. (7 marks)

Ornella distributors are specialists in the distribution of a detergent manufactured SP Chemicals Ltd. The company buys the detergent from SP Chemicals Ltd. at Sh.160 per litre for distribution purposes. However, this has been a controversial issue and the management of the company has sought your expert advice on the following stock control policies:
(a) There is a recommendation the Managing Director (MD) that applying the economic order quantity (EOQ) model is the only optimal way of improving the stock holding policy. The company’s annual demand is estimated to be 432,000 litres which the MD assumes to be evenly distributed over 330 working days in a year. The cost of delivery is estimated to be Sh. 6,000 per order and the annual variable holding cost per litre at Sh. 2.4 plus 1% of the purchase price. The company’s policy is to order 20,000 litres each time and the lead time for an order is 3 working days.
(i) Calculate the EOQ, frequency of ordering and any annual cost savings if the company abandons the present inventory policy for the EOQ model. (6 marks)
(ii) The supplier has intimated that he will offer quantity discounts on purchases of quantities above 20,000 as follows:
20,001 – 37,000 litres Sh.150 per liter
37,001 litres and above Sh.140 per litre
Advice the distributor on the most optimal inventory policy. (4 marks)
(b) The company’s finance director (FD points out that demand within the ten days’ lead time has not been entirely even over the past year causing stock outs. In case of a stock-out, it would be necessary to obtain the detergent a special courier service at an additional cost of Sh.10 per litre. In this regard, he has given the frequency of the lead time demand over the last year as follows:
Lead time demand per day                 Frequency                   Probability
(No. of litres)
1,700                                                                   2                                        0.02
1,500                                                                 10                                       0.10
1,400                                                                20                                       0.20
1,300                                                                30                                       0.30
1,100                                                                25                                        0.25
1,000                                                               13                                        0.13
(i) Assuming that the stock out cost is reliable and that the order quantity will be constant for all the orders in a year, calculate the safety stock level the company should maintain throughout. (6 marks)
(ii) Assuming that stock out cost is unreliable but the management have established a service level of 90% that stock will always be available, calculate the optimal safety stock level. (4 marks)
NB: Ignore the supplier’s quantity discount offer.
