[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.
In project management, resource leveling is defined by A Guide to the Project Management Body of Knowledge (PMBOK Guide) as "A technique in which start and finish dates are adjusted based on resource limitation with the goal of balancing demand for resources with the available supply."
Consumption smoothing is an economic concept for the practice of optimizing a person's standard of living through an appropriate balance between savings and consumption over time. An optimal consumption rate should be relatively similar at each stage of a person's life rather than fluctuate wildly.
Project Management Professional (PMP) is an internationally recognized professional designation offered by the Project Management Institute (PMI). [1] As of 31 July 2020, there are 1,036,368 active PMP-certified individuals and 314 chartered chapters across 214 countries and territories worldwide. [2]
Having said that, dynamic analysis reveals that order smoothing can degrade performance in the presence of demand shocks. The opposite bias (i.e., over-reaction to mismatches), on the other hand, degrades the stationary performance but can increase dynamic performance; controlled over-reaction can aid the system reach its new goals quickly.
Production leveling, also known as production smoothing or – by its Japanese original term – heijunka (平準化), [1] is a technique for reducing the mura (unevenness) which in turn reduces muda (waste). It was vital to the development of production efficiency in the Toyota Production System and lean manufacturing. The goal is to produce ...
The project schedule is a calendar that links the tasks to be done with the resources that will do them. It is the core of the project plan used to show the organization how the work will be done, commit people to the project, determine resource needs, and used as a kind of checklist to make sure that every task necessary is performed.
The filter was popularized in the field of economics in the 1990s by economists Robert J. Hodrick and Nobel Memorial Prize winner Edward C. Prescott, [1] though it was first proposed much earlier by E. T. Whittaker in 1923. [2], see Whittaker-Henderson smoothing. The Hodrick-Prescott filter is a special case of a smoothing spline. [3]
