Workforce Modeling
Workforce modeling is the process of aligning the demand for skilled labor with the availability and preferences of skilled workers (Supply and demand, supply). It uses Mathematical model, mathematical models to support tasks such as sensitivity analysis, scheduling, and workload forecasting. This approach is commonly applied in industries with complex labor regulations, certified workers, and varying levels of demand, including healthcare, Public security, public safety, and retail. Workforce modeling solutions often include software tools that help determine staffing needs based on workload volume across different periods, such as times of day, days of the week, or seasonal cycles. Definition The term can be differentiated from traditional staff Schedule (workplace), scheduling. Staff scheduling is rooted in time management. Besides demand orientation, workforce modeling also incorporates the forecast of the workload and the required staff, the integration of workers into the s ...

Demand
In economics, demand is the quantity of a goods, good that consumers are willing and able to purchase at various prices during a given time. In economics "demand" for a commodity is not the same thing as "desire" for it. It refers to both the desire to purchase and the ability to pay for a commodity. Demand is always expressed in relation to a particular price and a particular time period since demand is a flow concept. Flow is any variable which is expressed per unit of time. Demand thus does not refer to a single isolated purchase, but a continuous flow of purchases. Factors influencing demand The factors that influence the decisions of household (individual consumers) to purchase a commodity are known as the determinants of demand. Some important determinants of demand are: The price of the commodity: Most important determinant of the demand for a commodity is the price of the commodity itself. Normally there is an inverse relationship between the price of the commodity and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skilled Workers
A skilled worker is any worker who has special skill, training, or knowledge which they can then apply to their work. A skilled worker may have learned their skills through work experience, on-the-job training, an apprenticeship program or formal education. These skills often lead to better outcomes economically. The definition of a skilled worker has seen change throughout the 20th century, largely due to the industrial impact of the Great Depression and World War II. Further changes in globalisation have seen this definition shift further in Western countries, with many jobs moving from manufacturing based sectors to more advanced technical and service based roles. Examples of formally educated skilled labor include engineers, scientists, doctors and teachers, while examples of less formally educated workers include crane operators, CDL truck drivers, machinists, drafters, plumbers, craftsmen, cooks and bookkeepers.

Supply And Demand
In microeconomics, supply and demand is an economic model of price determination in a Market (economics), market. It postulates that, Ceteris_paribus#Applications, holding all else equal, the unit price for a particular Good (economics), good or other traded item in a perfect competition, perfectly competitive market, will vary until it settles at the market clearing, market-clearing price, where the quantity demanded equals the quantity supplied such that an economic equilibrium is achieved for price and quantity transacted. The concept of supply and demand forms the theoretical basis of modern economics. In situations where a firm has market power, its decision on how much output to bring to market influences the market price, in violation of perfect competition. There, a more complicated model should be used; for example, an oligopoly or product differentiation, differentiated-product model. Likewise, where a buyer has market power, models such as monopsony will be more a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Model
A mathematical model is an abstract and concrete, abstract description of a concrete system using mathematics, mathematical concepts and language of mathematics, language. The process of developing a mathematical model is termed ''mathematical modeling''. Mathematical models are used in applied mathematics and in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in non-physical systems such as the social sciences (such as economics, psychology, sociology, political science). It can also be taught as a subject in its own right. The use of mathematical models to solve problems in business or military operations is a large part of the field of operations research. Mathematical models are also used in music, linguistics, and philosophy (for example, intensively in analytic philosophy). A model may help to explain a system and to study the effects of different components, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensitivity Analysis
Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be divided and allocated to different sources of uncertainty in its inputs. This involves estimating sensitivity indices that quantify the influence of an input or group of inputs on the output. A related practice is uncertainty analysis, which has a greater focus on uncertainty quantification and propagation of uncertainty; ideally, uncertainty and sensitivity analysis should be run in tandem. Motivation A mathematical model (for example in biology, climate change, economics, renewable energy, agronomy...) can be highly complex, and as a result, its relationships between inputs and outputs may be faultily understood. In such cases, the model can be viewed as a black box, i.e. the output is an "opaque" function of its inputs. Quite often, some or all of the model inputs are subject to sources of uncertainty, including errors of measurement, er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Security
Public security or public safety is the prevention of and protection from events that could endanger the safety and security of the public from significant danger, injury, or property damage. It is often conducted by a state government to ensure the protection of citizens, persons in their territory, organizations, and institutions against threats to their well-being, survival, and prosperity. The public safety issues that a municipality, county, regional, or federal jurisdiction may handle include crimes (ranging from misdemeanors to felonies), structure fires, conflagrations, medical emergencies, mass-casualty incidents, disasters, terrorism, and other concerns. Public safety organizations are organizations that conduct public safety. They generally consist of emergency services and first responders such as law enforcement, fire services, emergency medical services, security forces, and military forces. They are often operated by a government, though some private p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schedule (workplace)
A schedule, often called a rota or a roster, is a list of employees, and associated information e.g. location, department, working times, responsibilities for a given time period e.g. week, month or sports season. A schedule is necessary for the day-to-day operation of many businesses e.g. retail store, manufacturing facility and some offices. The process of creating a schedule is called scheduling. An effective workplace schedule balances the needs of stakeholders such as management, employees and customers. A ''daily'' schedule is usually ordered chronologically, which means the first employees working that day are listed at the top, followed by the employee who comes in next, etc. A ''weekly'' or ''monthly'' schedule is usually ordered alphabetically, employees being listed on the left hand side of a grid, with the days of the week on the top of the grid. In shift work, a schedule usually employs a recurring shift plan. A schedule is most often created by a man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Management
Time management is the process of planning and exercising conscious control of time spent on specific activities—especially to increase effectiveness, efficiency and productivity. Time management involves demands relating to work, social life, family, hobbies, personal interests and commitments. Using time effectively gives people more choices in managing activities. Time management may be aided by a range of skills, tools and techniques, especially when accomplishing specific tasks, projects and goals complying with a due date. Initially, the term time management encompassed only business and work activities, but eventually the term comprised personal activities as well. A time management system is a designed combination of processes, tools, techniques and methods. Time management is usually a necessity in managing projects, as it determines the project completion time and scope. Cultural views Differences in the way a culture views time can affect the way their tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Programming
Linear programming (LP), also called linear optimization, is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements and objective are represented by linear function#As a polynomial function, linear relationships. Linear programming is a special case of mathematical programming (also known as mathematical optimization). More formally, linear programming is a technique for the mathematical optimization, optimization of a linear objective function, subject to linear equality and linear inequality Constraint (mathematics), constraints. Its feasible region is a convex polytope, which is a set defined as the intersection (mathematics), intersection of finitely many Half-space (geometry), half spaces, each of which is defined by a linear inequality. Its objective function is a real number, real-valued affine function, affine (linear) function defined on this polytope. A linear programming algorithm finds a point in the po ...

System Dynamics
System dynamics (SD) is an approach to understanding the nonlinear behaviour of complex systems over time using stocks, flows, internal feedback loops, table functions and time delays. Overview System dynamics is a methodology and mathematical modeling technique to frame, understand, and discuss complex issues and problems. Originally developed in the 1950s to help corporate managers improve their understanding of industrial processes, SD is currently being used throughout the public and private sector for policy analysis and design. Convenient graphical user interface (GUI) system dynamics software developed into user friendly versions by the 1990s and have been applied to diverse systems. SD models solve the problem of simultaneity (mutual causation) by updating all variables in small time increments with positive and negative feedbacks and time delays structuring the interactions and control. The best known SD model is probably the 1972 ''The Limits to Growth''. This model fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
