- Table 2 contains information about an environmental cleanup
project in the township of Hiles. Shorten the project 3 weeks by
finding the minimum-cost schedule. Assume that project indirect
costs and penalty costs are negligible. Identify activities to
crash while minimizing the additional crash costs.
- What is the project’s duration if only normal times are used?
- What is the minimum-cost schedule?
- What is the critical path for the minimum-cost schedule?
