RISK MODELING

The assignment content discusses risk modeling and the probability distribution of total cost of demolition. It presents a simulation summary information table showing the statistics for the cost of contingencies and change in risk class, with minimum and maximum values indicating a huge difference between the two. The standard deviation value is high, reflecting significant deviation in overall cost across different locations. The total cost of demolition is £132, 81,470.59, higher than expected values, suggesting a need for cost-cutting measures to reduce the gap.

Interpretation
Maximum risk category for mitigation is 11. There are many areas where mitigation expenses are almost reduced to zero.
Moreover, expenditures are made within the limit. However, risk in many areas is very high and due to this reason simulation model
generate high risk category. It can be said that further steps need to be taken to reduce risk.

It can be observed from the table that maximum value of cost of demolition is 20,907,000.00 and min value of it is 7,951,000.00,
which indicate that there is huge difference between minimum and maximum cost of demolition. It can be said that cost of demolition
varied from one location to another to great extent. Standard deviation value is 4,099,656.97, which reflect that huge deviation is
observed in overall cost of demolition across different locations. In case risk is uncertain, cost of demolition may increase at fast rate.
Total cost of demolition is 132, 81,470.59 and sum of total expected value is 99619. It can be said that cost of demolition is higher
than expected values. It can be said that there is need to take some more steps to improve performance. New ideas must be identified
of cost cutting in order to reduce gap between total cost and expected value.

Probability distribution of total cost of demolition
Explanation
Probability distribution chart reflects that in case of each mitigation item expenditure will remain in range of £1, 00,000 to £6,
and 00,000 as reflected by the uniform distribution diagram. Huge part of demolition is equal to £1, 00,000. Chart that is given above
also reflects that most of the mitigation purchase values will remain in range of £1, 00,000. There will be moderate number of items
whose value will be equal to £ 2, 00,000. There are only few items in mitigation purchase whose value is equal to £ 5, 00,000 and £ 6,
00,000. Hence, it is concluded that value of the most of mitigation purchase items is in range of £1, 00,000.
