Objectives can be set in all domains of activities, such as production, marketing, services, sales, R&D, human resources, finance, and information systems. Some objectives are collective, and some can be goals for each worker. Both make the task at hand seem attainable and enable the workers to visualize what needs to be done and how.
A large amount of work done in society is not captured in national accounts, because it is unpaid voluntary labour or unpaid household labour. The monetary value of this work can be estimated only from time use surveys. Thus, national accounting definitions of "production" are strongly biased towards activities which yield a money-income.
The main objective of TPM is to increase the overall equipment effectiveness (OEE) of plant equipment. TPM addresses the causes for accelerated deterioration and production losses while creating the correct environment between operators and equipment to create ownership. OEE has three factors which are multiplied to give one measure called OEE:
For example, an objective might be increasing sales revenue by ten percent. This would prevent the confusions and conflicts on whether it has been met between different stakeholders. Thirdly, an objective should be achievable and feasible. It also should be agreed by stakeholders, especially by employees. If they think it is un-achievable, it ...
An individual production system can be both push and pull; for example activities before the CODP may work under a pull system, while activities after the CODP may work under a push system. Classic EOQ model: trade-off between ordering cost (blue) and holding cost (red). Total cost (green) admits a global optimum.
The production function is a graphical or mathematical expression showing the relationship between the inputs used in production and the output achieved. Both graphical and mathematical expressions are presented and demonstrated. The production function is a simple description of the mechanism of income generation in production process.
Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. [1] The most common example is the (aggregate) labour productivity measure, one example of which is GDP per worker ...
The inputs to such problems are a list of jobs (also called processes or tasks) and a list of machines (also called processors or workers). The required output is a schedule – an assignment of jobs to machines. The schedule should optimize a certain objective function.
