Question One
Solai Ltd is a manufacturing Company that requires component GLB 50 in one of its
production lines. The components are bought from outside suppliers. From past
experience, the company has determined that the demand for the components can be
approximated by a normal distribution with a mean of 500 and a standard deviation of 10,
over the range 470 to 530.
There is an initial stock of 2000 components and the company has decided to order in
batches of 2,500 where never the stock level falls below 1,500 components. Again past
experience indicated that the time between the order being placed and delivery levels as
follows.

The unit cost of holding stock is Ksh 5 per week applied to the total stock held at the end
of each week. The cost associated with placing an order is Ksh 500 and the unit cost of
being out of stock is Kshs 200 per week. The company does all its accounting at the end
of the week and all ordering and delivery occur at the beginning of a week.
Required
Estimate the average cost per week of the above policy, using simulation analysis and the
following random numbers
For demand: 034743738636964736614698
6371623326168044560111410959
7742467662
For lead time: 957310765174
Hint:
• Use 15 trial runs
• Round off the demand probability to 3 decimal places and estimate in ranges of 5.

Question Two
Large service organization, such as banks and hospitals, used to be noted for their lack of
standard costing systems, and their relatively unsophisticated budgeting and control

accounting techniques.

Explain the features of large service organizations that encourage the application
of
