[2]: 185 Thus, while resource leveling can be considered a constraint in order to adjust with certain resource supply limitation, for example, not to over-work some human resources, resource smoothing can be considered a useful method to solve the problem of a more flexible constraint if time of a deadline is a stronger constraint.

Aggregation differs from ordinary composition in that it does not imply ownership. In composition, when the owning object is destroyed, so are the contained objects. In aggregation, this is not necessarily true. For example, a university owns various departments (e.g., chemistry), and each department has a number of professors. If the ...
Resource-leveling can take the "work demand" and balance it against the resource pool availability for the given week. The goal is to create this weekly schedule in advance of performing the work. Without resource-leveling the organization (planner, scheduler, supervisor) is most likely performing subjective selection.
A resource-leveled schedule may include delays due to resource bottlenecks (i.e., unavailability of a resource at the required time), and may cause a previously shorter path to become the longest or most "resource critical" path while a resource-smoothed schedule avoids impacting the critical path by using only free and total float. [14]
In a project plan, the critical chain is the sequence of both precedence- and resource-dependent tasks that prevents a project from being completed in a shorter time, given finite resources. If resources are always available in unlimited quantities, then a project's critical chain is identical to its critical path method .
Determining Resource Cost rates: The cost of goods and labor by unit gathered through estimates or estimation. Bottom Up estimating: Using the lowest level of work package detail and summarizing the cost associated with it. Then rolling it up to a higher level aimed and calculating the entire cost of the project.

Exception safety is provided for stack resources (resources that are released in the same scope as they are acquired) by tying the resource to the lifetime of a stack variable (a local variable declared in a given scope): if an exception is thrown, and proper exception handling is in place, the only code that will be executed when exiting the ...
