Resource Smoothing
In project management, resource smoothing is defined by '' A Guide to the Project Management Body of Knowledge'' (''PMBOK Guide'') as a "resource optimization technique in which free and total float are used without affecting the critical path" of a project. Resource smoothing as a resource optimization technique has only been introduced in the Sixth Edition of the PMBOK Guide (since 2017) and did not exist in its previous revisions. It is posed as an alternative and a distinct resource optimization technique beside resource leveling. The main difference between resource leveling and resource smoothing is that while resource leveling uses the available float, thus may affect a critical path, resource smoothing uses free and total float without affecting any of the critical paths. 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 consid ...

Project Management
Project management is the process of supervising the work of a Project team, team to achieve all project goals within the given constraints. This information is usually described in project initiation documentation, project documentation, created at the beginning of the development process. The primary constraints are Scope (project management), scope, time and budget. The secondary challenge is to operations research, optimize the Resource allocation, allocation of necessary inputs and apply them to meet predefined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are established, they should influence all decisions made by other people involved in the project– for example, project managers, designers, contractors and subcontractors ...

A Guide To The Project Management Body Of Knowledge
The Project Management Body of Knowledge (PMBOK) is a set of standard terminology and guidelines (a body of knowledge) for project management. The body of knowledge evolves over time and is presented in ''A Guide to the Project Management Body of Knowledge'' (''PMBOK Guide''), a book whose seventh edition was released in 2021. This document results from work overseen by the Project Management Institute (PMI), which offers the CAPM and PMP certifications. Much of the ''PMBOK Guide'' is unique to project management such as critical path method and work breakdown structure (WBS). The ''PMBOK Guide'' also overlaps with general management regarding planning, organising, staffing, executing and controlling the operations of an organisation. Other management disciplines which overlap with the ''PMBOK Guide'' include financial forecasting, organisational behaviour, management science, budgeting and other planning methods. History Earlier versions of the ''PMBOK Guide'' were recogni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Path Method
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for schedule (project management), scheduling a set of project activities. A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish. It is commonly used in conjunction with the program evaluation and review technique (PERT). History The CPM is a project-modeling technique developed in the late 1950s by Morgan R. Walker of DuPont and James E. Kelley Jr. of Remington Rand. Kelley and Walker related their memories of the development of CPM in 1989. Kelley attributed the term "critical path" to the developers of the PERT, which was developed at about the same time by Booz Allen Hamilton and the U.S. Navy. The precursors of what came to be known as critical path were developed and put into practice by DuPont between 1940 and 1943 and contributed to the success of the Manhattan Project.

Project
A project is a type of assignment, typically involving research or design, that is carefully planned to achieve a specific objective. An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system (work system), possibly staffed by teams (within or across organizations) to accomplish particular tasks under time constraints. A project may form a part of wider programme management or function as an ''ad hoc'' system. Open-source software "projects" or artists' musical "projects" (for example) may lack defined team-membership, precise planning and/or time-limited durations. Overview The word ''project'' comes from the Latin word ''projectum'' from the Latin verb ''proicere'', "before an action", which in turn comes from ''pro-'', which denotes precedence, something that comes before ...

Resource Leveling
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." Resource leveling problem could be formulated as an optimization problem. The problem could be solved by different optimization algorithms such as exact algorithms or meta-heuristic methods. When performing project planning activities, the manager will attempt to schedule certain tasks simultaneously. When more resources such as machine A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromol ...s or people are needed than are available, or perhaps a specific person is needed in both tasks, the tasks ...

Float (project Management)
In project management, float or slack is the amount of time that a task in a project network can be delayed without causing a delay to: * subsequent tasks ("''free float''") * project completion date ("''total float''"). ''Total float'' is associated with the path. If a project network chart/diagram has 4 non-critical paths, then that project would have 4 ''total float'' values. The ''total float'' of a path is the combined ''free float'' values of all activities in a path. The ''total float'' represents the schedule flexibility and can also be measured by subtracting early start dates from late start dates of path completion. Float is core to critical path method, with the total floats of noncritical activities key to computing the critical path drag of an activity, i.e., the amount of time it is adding to the project's duration.* Example Consider the process of replacing a broken pane of glass in the window of your home. There are various component activities involved in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optimization
Mathematical optimization (alternatively spelled ''optimisation'') or mathematical programming is the selection of a best element, with regard to some criteria, from some set of available alternatives. It is generally divided into two subfields: discrete optimization and continuous optimization. Optimization problems arise in all quantitative disciplines from computer science and engineering to operations research and economics, and the development of solution methods has been of interest in mathematics for centuries. In the more general approach, an optimization problem consists of maxima and minima, maximizing or minimizing a Function of a real variable, real function by systematically choosing Argument of a function, input values from within an allowed set and computing the Value (mathematics), value of the function. The generalization of optimization theory and techniques to other formulations constitutes a large area of applied mathematics. Optimization problems Opti ...

Metaheuristic
In computer science and mathematical optimization, a metaheuristic is a higher-level procedure or heuristic designed to find, generate, tune, or select a heuristic (partial search algorithm) that may provide a sufficiently good solution to an optimization problem or a machine learning problem, especially with incomplete or imperfect information or limited computation capacity. Metaheuristics sample a subset of solutions which is otherwise too large to be completely enumerated or otherwise explored. Metaheuristics may make relatively few assumptions about the optimization problem being solved and so may be usable for a variety of problems. Their use is always of interest when exact or other (approximate) methods are not available or are not expedient, either because the calculation time is too long or because, for example, the solution provided is too imprecise. Compared to optimization algorithms and iterative methods, metaheuristics do not guarantee that a globally optimal sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Allocation
In economics, resource allocation is the assignment of available resources to various uses. In the context of an entire economy, resources can be allocated by various means, such as markets, or planning. In project management, resource allocation or resource management is the scheduling of activities and the resources required by those activities while taking into consideration both the resource availability and the project time. Economics In economics, the field of public finance deals with three broad areas: macroeconomic stabilization, the distribution of income and wealth, and the allocation of resources. Much of the study of the allocation of resources is devoted to finding the conditions under which particular mechanisms of resource allocation lead to Pareto efficient outcomes, in which no party's situation can be improved without hurting that of another party. Strategic planning In strategic planning, resource allocation is a plan for using available resources, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
