Question

An architectural firm has three types of clients: "G" = "green/new": "EC" = experienced with a complex project, and "ES" = experienced with a simple project. The process flow for these types of projects and the staffing of each of the stages are provided below in the diagram: G- Needs assessment: 2 planners Design: 5 architects Structural engineering: 2 engineers The processing times for the different types of jobs (in days) are listed in the following table. Processing time (days) Needs Design Engineering Demand (clients/day) 0.25 0.10 0.05 15 25 EC ES 10

Answer 1

Solution:

$Implied\ Utilisation = \frac{Total\ Demand\ Inflow}{Total\ Capacity}$

Hence,

a)

- Implied Utilisation of Needs,

Total Demand = 0.25/day
Total Capacity = 1/7 per day.

$Implied\ Utilisation = \frac{0.25}{\frac{1}{7}} = 1.75 = 175\%$

Hence, the implied utilization of Needs is 175%

- Implied Utilisation of Design,

Total Demand = 0.40/day (sum of all 3 demands 0.25+0.10+0.05)
Total Capacity = 3/50 per day.

$Implied\ Utilisation = \frac{0.40}{\frac{3}{50}} = 6.66 = 666.66\%$

Hence, the implied utilization of Design is 666.66%

- Implied Utilisation of Engineering,

Total Demand = 0.35/day
Total Capacity = 0.2/day

$Implied\ Utilisation = \frac{0.35}{0.2} = 1.75 = 175\%$

Hence, the implied utilization of Engineering is 175%

b)

- Needs:

Actual Flow = 0.25/day
Maximum Flow = 0.25/day
